1. The first curve is [tex]y=x^2+16[/tex]

The area under this curve on the interval [-1, 5] is given by:

[tex]\int\limits^5_{-1} {x^2+16} \, dx[/tex]

We integrate to obtain:

[tex]\frac{1}{3}x^3+16x|_{-1}^5[/tex]

56​% of men consider themselves professional baseball fans. you randomly select 10 men and ask each if he considers himself a professional baseball fan. find the probability that the number who consider themselves baseball fans is​ (a) exactly​ five, (b) at least​ six, and​ (c) less than four.

Answers

(a) ≈ 0.202, (b) ≈ 0.878, (c) ≈ 0.376, calculated using binomial probability formula with 56% chance for baseball fans.

To solve this problem, we can use the binomial probability formula since we have a fixed number of trials (selecting 10 men) and each trial (man) has two possible outcomes (considering themselves a baseball fan or not).

The binomial probability formula is:

[tex]\[ P(X = k) = \binom{n}{k} \times p^k \times (1 - p)^{n - k} \][/tex]

Where:

- [tex]\( P(X = k) \)[/tex] is the probability of getting exactly \( k \) successes,

- [tex]\( n \)[/tex] is the number of trials (in this case, 10 men),

- [tex]\( k \)[/tex] is the number of successes we are interested in (number of men considering themselves baseball fans),

- [tex]\( p \)[/tex] is the probability of success on each trial (in this case, 56% or 0.56),

- [tex]\( \binom{n}{k} \)[/tex] is the binomial coefficient, representing the number of ways to choose [tex]\( k \)[/tex] successes from [tex]\( n \)[/tex] trials.

Let's solve each part of the problem:

(a) Finding the probability of exactly five men considering themselves baseball fans:

[tex]\[ P(X = 5) = \binom{10}{5} \times (0.56)^5 \times (1 - 0.56)^{10 - 5} \][/tex]

(b) Finding the probability of at least six men considering themselves baseball fans. This is the sum of probabilities of having 6, 7, 8, 9, or 10 successes:

[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \][/tex]

(c) Finding the probability of less than four men considering themselves baseball fans. This is the sum of probabilities of having 0, 1, 2, or 3 successes:

[tex]\[ P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) \][/tex]

Let's calculate each part:

(a)

[tex]$\begin{aligned} & P(X=5)=\left(\begin{array}{c}10 \\ 5\end{array}\right) \times(0.56)^5 \times(1-0.56)^{10-5} \\ & =\left(\begin{array}{c}10 \\ 5\end{array}\right) \times(0.56)^5 \times(0.44)^5 \\ & \approx 0.202\end{aligned}$[/tex]

(b)

[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \]\[ = \sum_{k=6}^{10} \binom{10}{k} \times (0.56)^k \times (0.44)^{10 - k} \]\[ \approx 0.878 \][/tex]

(c)

[tex]$\begin{aligned} & P(X < 4)=P(X=0)+P(X=1)+P(X=2)+P(X=3) \\ & =\sum_{k=0}^3\left(\begin{array}{c}10 \\ k\end{array}\right) \times(0.56)^k \times(0.44)^{10-k} \\ & \approx 0.006+0.034+0.111+0.225 \\ & \approx 0.376\end{aligned}$[/tex]

So, the probabilities are:

(a) [tex]\( \approx 0.202 \)[/tex]

(b) [tex]\( \approx 0.878 \)[/tex]

(c) [tex]\( \approx 0.376 \)[/tex]

Nicole runs a farm stand that sells bananas and peaches. Each pound of bananas sells for $2 and each pound of peaches sells for $3.25. Nicole sold 3 more pounds of bananas than pounds of peaches and made $231.75 altogether. Write a system of equations that could be used to determine the number of pounds of bananas sold and the number of pounds of peaches sold. Define the variables that you use to write the system.

Answers

Answer:

The required system of equations is:

2x + 3.25y = 231.75

x = y + 3

where x is the number of pounds of bananas and y is the number of pounds of peaches

Explanation:

1- Defining the variables:

Assume that the number of pounds of bananas sold is x

Assume that the number of pounds of peaches sold is y

2- Setting the system of equations:

We are given that:

i. Each pound of bananas sells for $2

  Money gained from selling x pounds of bananas is 2x

ii. Each pound of peach sells for $3.23

   Money gained from selling y pounds of peaches is 3.25y

iii. Nicole made $231.75 in total. This means that:

    2x + 3.25y = 231.75 .................> equation I

iv. Nicole sold 3 more pounds of bananas than pounds of peaches. This

    means that:

    pounds of bananas = pounds of peaches + 3

    x = y + 3 ..................> equation II

3- Solving the equations (if required):

In equation II, we have: x = y + 3

Substitute with equation II in equation I and solve for y as follows:

2x + 3.25y = 231.75

2(y+3) + 3.25y = 231.75

2y + 6 + 3.25y = 231.75

5.25y = 231.75 - 6

5.25y = 225.75

y = 43

Substitute with y in equation II to get x:

x = y + 3

x = 43 + 3 = 46

Based on the above:

Number of pounds of bananas = x = 46 pounds

Number of pounds of peaches = y = 43 pounds

Hope this helps :)

The coordinates of the vertices of triangle cde are c (-3, 1), d (-1, 4) and e (-6, 4). a transformation applied to triangle cde creates a congruent triangle sqr. the new coordinates of two vertices are q(-1, 6) and r(-6, 6). what are the coordinates of s?

Answers

Answer:

The coordinates of point s are (-3 , 3)

Step-by-step explanation:

* Lets revise some transformation

- If the point (x , y) translated horizontally to the right by h units

 then the new point  = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point  = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point  = (x  , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point  = (x  , y - k)

* Now lets solve the problem

∵ The vertices of triangle cde are c (-3 , 1) , d (-1 , 4) , e (-6 , 4)

∵ The new coordinates of two vertices are q (-1 , 6) , r (-6 , 6)

- The image of point d is q and the image of point e is r

∵ Point d = (-1 , 4) and point q = (-1 , 6)

∵ Point e = (-6 , 4) and point r = (-6 , 6)

- The x-coordinate has no change but the y-coordinate added by 2

∴ The triangle cde translated vertically up by 2 units to create the

  congruent triangle sqr

- Lets translate point c two units up to find the coordinates of point s

∵ Point c = (-3 , 1)

∴ Poin s = (-3 , 1 + 2) = -3 , 3)

* The coordinates of point s are (-3 , 3)

Answers

Answer:

The height of the cone is [tex]48\ in[/tex]

Step-by-step explanation:

step 1

Find the radius of the base of cone

we know that

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2} h[/tex]

we have

[tex]V=12,288\pi\ in^{3}[/tex]

[tex]tan(30\°)=\frac{r}{h}[/tex]  ---> remember that the vertex angle of the vertical cross section is 60 degrees

so

[tex]r=(h)tan(30\°)[/tex]

[tex]r=(h)\frac{\sqrt{3}}{3}[/tex]

substitute the values and solve for h

[tex]12,288\pi=\frac{1}{3}\pi ((h)\frac{\sqrt{3}}{3})^{2} h[/tex]

[tex]36,864=\frac{h^{3}}{3}[/tex]

[tex]h^{3}=110,592[/tex]

A) Dilation

B) Rotation

C) Reflection

D) Translation

Answers

Dilation since one image is bigger than the other

Final answer:

A dilation transformation must be included to result in quadrilateral T.

Explanation:

To result in quadrilateral T, a dilation transformation must be included. A dilation is a transformation that changes the size of the figure without changing its shape. In this case, the side lengths of quadrilateral T are twice as long as those of quadrilateral S, indicating a scaling factor of 2. Therefore, a dilation is needed to scale up the size of quadrilateral S by a factor of 2 to obtain quadrilateral T.

Of the 500000 people (age 16+) in a particular country 300000 people are in the labor force. of the 240000 are employed and 60000 are unemployed what is the unempoyment rate

Answers

Answer:

12%

Step-by-step explanation:

60000 people are unemployed, out of 500000 people.

That means that 60000/500000 of the population is unemployed.

Simplify: 60000/500000 = 6/50 = 0.12 = 12%

The overall unemployment rate is will be 12% based on the given data.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Total people = 5000000

40000 are employed and 60000 are unemployed out of 300000 people are in the labor force.

The % unemployment rate = (60000)/500000 x 100 = 12%

Hence "The overall unemployment rate is will be 12% based on the given data".

  B.  The sum of the squares of the two smaller sides is equal to the square of the third side.

Step-by-step explanation:

It can be helpful to recognize that the given side lengths, 12, 16, 20 are in the ratio 3:4:5, a recognizable Pythagorean triple. That is, you may know already that the triangle is a right triangle and the sum of squares of the short sides is equal to the square of the longest side (choice B).

In case you aren't aware of common Pythagorean triples, or didn't recognize these numbers, you can try the options to see which fits.

A. The sum of the two smaller sides is 12 +16 = 28. It is NOT equal to the third side, 20.

__

B. The sum of the squares of the two smaller sides is 12^2 + 16^2 = 144 + 256 = 400. This IS equal to the square of the third side: 20^2 = 400.

__

C. The absolute value of the difference between the squares of the two smaller sides is |256 -144| = 112. This is NOT equal to the square of the third side, 20^2 = 400.

Final answer:

To find the missing length, use the Pythagorean theorem by setting up an equation with the given lengths in a right triangle. Solve for the missing length using the equation and determine the correct answer.

Explanation:

To find the missing length, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Let's assume the missing length is represented by 'x'. Using the theorem, we can set up the equation as follows:

a = 16b = 30c = x

We can solve for 'x' by substituting the given lengths into the equation and solving for 'x'.

x2 = a2 + b2

x2 = 162 + 302

x2 = 256 + 900

x2 = 1156

x = √1156

x = 34

Therefore, the missing length indicated is 34. Option B) 36 is not the correct answer.

Answer:

Step-by-step explanation:

We know a maximum point on the height vs. time curve is at t=16 seconds. Then the height function can be written by filling in the known values in ...

  h(t) = (center height) + (wheel radius)·cos((frequency)·2π·(t -(time at max height)))

Since t is in seconds, we want the frequency in revolutions per second. That will be ...

  (3.2 rev/min)·(1 min)/(60 sec) = 3.2/60 rev/sec = 4/75 rev/sec

Then our height function is ...

  h(t) = 59 + 45·cos(8π/75·(t -16))

9 minutes is 9·60 sec = 540 sec, so we want to find the value of h(540).

  h(540) = 59 + 45·cos(8π/75·(540 -16))

The cosine function is a maximum when its argument is zero. We used the process of function translation to translate the maximum point to t=16 from t=0. That is, we replaced t in the usual cosine function with (t-16).

We can also evaluate the cosine function by subtracting multiples of 2π from the argument. When we do that, we find that Shirley's height at 9 minutes is the same as it is after 15 seconds. Some calculators evaluate smaller cosine arguments more accurately than they do larger argument values.

[tex]x-2 => f(x)=x^{3}-2x^{2}-x+2\\x+3=>f(x)=x^{3}-3x^{2} -13x+15\\x+4=>f(x)=-x^{3}+13x-12\\x+5=>f(x)=x^{4}+3x^{3}-8x^{2}+5x-25[/tex]

Step-by-step explanation:

The value of a function will be zero if the factor is put in it. In order to check whether a factor is of a function or not we will put the value of x from that factor in the function:

So

x-2 = 0 => x=2

Putting in first function

[tex]x^{3}-3x^{2} -13x+15\\=(2)^{3}-3(2)^{2} -13(2)+15\\=8-3(4)-26+15\\=8-12-26+15\\=23-38\\=-15 \neq 0\\[/tex]

So x-2 is not a factor of first function.

Putting in second function

[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(2)^{4}+3(2)^{3}-8(2)^{2}+5(2)-25\\=16+3(8)-8(4)+10-25\\=16+24-32+10-25\\=-7\neq 0[/tex]

So x-2 is also not a factor of second function.

Putting in third function:

[tex]f(x)=x^{3}-2x^{2}-x+2\\ =(2)^{3}-2(2)^{2}-2+2\\=8-2(4)-2+2\\=8-8-2+2\\=0[/tex]

So x-2 is factor of third function.

...........................

For x+3

x+3=0

x=-3

First function:

[tex]f(x)=x^{3}-3x^{2} -13x+15\\=(-3)^{3}-3(-3)^{2} -13(-3)+15\\=-27-3(9)+39+15\\=-27-27+39+15\\=-54+54\\=0\\[/tex]

So x+3 is a factor of first function.

.............................

For x+4

x+4=0

x=-4

As we have already found the factors of first and third function, we will now only check second and fourth function.

[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(-4)^{4}+3(-4)^{3}-8(-4)^{2}+5(-4)-25\\=256+3(-64)-8(16)-20-25\\=256-192-128-20-25\\-109\neq 0[/tex]

So x+4 is not a factor of second function.

Putting in fourth function:

[tex]f(x)=-x^{3}+13x-12\\ =-(-4)^{3}+13(-4)-12\\=64-52-12\\=64-64\\=0\\[/tex]

So x+4 is a factor of fourth function

..........................

For x+5=0

x=-5

Since only one function is remaining we'll only check for that.

[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(-5)^{4}+3(-5)^{3}-8(-5)^{2}+5(-5)-25\\=625+3(-125)-8(25)-25-25\\=625-375-200-25-25\\=0\\[/tex]

2(x + 7) + 3x = 12
What is the first step in solving this equation for x?
A) 2x + 14 + 3x = 12
B) 2x + 7 + 3x = 12
C) 2x + 14 = 9
Eliminate
D) 5x = -2

Answers

A would be the very first step in solving the equation for x

You have to distribute 2 to x and 7.

2(x + 7) + 3x = 12

2x + 14 +3x = 12

Answer:

A) 2x + 14 + 3x = 12

Step-by-step explanation:

The first step is to distribute the 2

2(x + 7) + 3x = 12

2x+14 +3x =12

Then we combine like terms

5x+14 =12

Subtract 14 from each side

5x+14-14=12-14

5x = -2

Then divide each side by 5

5x/4 = -2/5

x = -2/5

In the figure, m∠1 = m∠2 = 22 and m∠3 = m∠4 = 123. From this, you can conclude that m∠TKL = _____


a. 22.


b. . 57.


c. 35.


d. 47.

Answers

Answer:

57°

Step-by-step explanation:

Angle 3 is supplementary to angle TKL.  That means they add up to 180°.  Therefore, 180° - 123° = 57°

Answer:

57°

Step-by-step explanation:

You can notice that by putting ∠3 and ∠TKL together you have a flat angle.

A flat angle has 180 degrees.

so, you can say that m∠3 and m∠TKL add 180 degrees, then they are supplementary angles.

Remember: Two angles are supplementary if they add 180 degrees.

Then, as you know m∠3=123°:

m∠3 + m∠TKL=180°

123 + m∠TKL=180°

m∠TKL=180° - 123°

m∠TKL=57°

Vanessa bought a house for $268,500. She has a 30 year mortgage with a fixed rate of 6.25%. Vanessa’s monthly payments are $1,595.85. How much was Vanessa’s down payment? a. $9,314.45 b. $16,781.25 c. $40,275.00 d. $53,040.00

Answers

Answer:

Option a - $9,314.45

Step-by-step explanation:

Cost of the house = $268,500

Time of repayment = 30 years

Repayment is done monthly, so number of repayments = 30 X 12 = 360

Monthly Payment = $1595.85

Rate of interest per payment period = [tex]\frac{.0625}{12}[/tex]

So, Present value of monthly payments = 1595.85 X  [tex]\frac{(1+\frac{.0625}{12})^{360}-1}{(1+\frac{.0625}{12})^{360}*(\frac{.0625}{12})}[/tex]

= $259,185.55

So, Vanessa's down payment = $268,500 - $259,185.55 = $9,314.45

Hope it helps.

Thank you !!

A paint store offers 15 different shades of blue. how many different ways could you purchase 3 shades of blue

Answers

Answer:

3.9230231e+12

Step-by-step explanation:

15! is 15 times 14 times 13 times 12 times 11 times 10 times 9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1 then times 3 because 3 shades of blue.

The number of different ways to purchase 3 shades of blue from 15 options is 455 different ways.

The question is asking about the number of combinations of 3 shades of blue that can be chosen from a total of 15 different shades. To calculate this, we use the formula for combinations without repetition, which is C(n, k) = n! / (k! * (n - k)!), where n is the total number of items to choose from, and k is the number of items to choose. In this case, n is 15 and k is 3.

First, we calculate the factorial of n, which is 15! (15 factorial), then the factorial of k, which is 3!, and finally the factorial of n - k, which is 12!. Putting these into the formula gives us:

C(15, 3) = 15! / (3! * 12!) = (15 * 14 * 13) / (3 * 2 * 1) = 455

Therefore, there are 455 different ways to choose 3 shades of blue from 15 different shades.

Answers

Answer:

D. 1,344 in^2

Step-by-step explanation:

The area of the standard placemats is 84 in^2. To make 6 we need to multiply that by 6. 84 in^2*6 is 1,344 in^2. Please rate brainliest. It would really help!

Answer:

Option D

Step-by-step explanation:

The standard size of the rectangular placemat is 14 inches by 16 inches.

So fabric needed to make a placemat = Length × Width

                                                               = 14 × 16

                                                               = 224 inch²

Now for 6 placemats fabric required = 6 × 224

                                                             = 1344 inch²

Option D is the answer.
