Answer: 6 outcomes

Step-by-step explanation: Since the first outcome is 2 and the second is 4 2 times 3 is ix since it is multiplying by 2 (2,4,6,8)

Final answer:

To find the total number of experimental outcomes for the entire experiment, multiply the number of outcomes for each step together, resulting in 24 total experimental outcomes.

Explanation:

The total number of experimental outcomes for the entire experiment can be calculated by multiplying the number of outcomes for each step together:

Number of outcomes for the first step: 3

Number of outcomes for the second step: 2

Number of outcomes for the third step: 4

Multiplying these numbers: 3 outcomes x 2 outcomes x 4 outcomes = 24 total experimental outcomes.

ANSWER

-7

EXPLANATION

The only numbers that have a distance of 7 from zero on the real number line are -7 and 7.

-7 is to the left of zero while 7 is to the right of zero.

But this two numbers are all 7 units from zero.

In other words, the absolute values of this numbers is 7.

[tex] |x| = 7[/tex]

[tex]x = - 7 \: or \: 7[/tex]

Hence the number Renee wrote is -7

The number that is the same distance from 0 as 7 on a number line, but in the opposite direction, is -7. This is because on a number line, +7 is 7 units to the right of 0 and -7 is 7 units to the left of 0.

In the field of Mathematics, the concept of a number line is a tool to understand the placement of numbers and their relative distance to one another. If Renee writes a number that is the same distance from 0 as 7 on a number line, but in the opposite direction, the number she writes would be -7.

This is because on a number line, the positive direction (to the right) signifies adding and the negative direction (to the left) signifies subtracting from zero. So the number -7 is 7 units distance to the left of 0. Similarly, the number 7 is 7 units distance to the right of 0. Hence, both numbers -7 and +7 are equidistant from 0, but lie in opposite directions on the number line.

Answer:

The weight of the parcel is approximately 6 kilograms.

Step-by-step explanation:

The weight of the parcel is  12 lbs and 8 oz.

1 lb = 16 oz

So,  8 oz =  lb.

That means,  12 lbs and 8 oz = (12 + 0.5) lbs = 12.5 lbs

Now, 1 lb = 454 g

So,  12.5 lbs = (12.5 × 454) g = 5675 g

As,  1 kilogram = 1000 g

That means, 1 g = 0.001 kilogram

So,  5675 g  kilograms. (Rounded to the nearest whole kilogram)

Thus, the weight of the parcel is approximately 6 kilograms.

Option b

Step-by-step explanation:

To solve this problem we must test if the function is even.

If f(-x) = f(x) then the function is even and is symmetric with respect to the y-axis.

If f(-x) = -f(x) then the function is odd and has symmetry with respect to the origin.

We have the function:

[tex]f(x) = \frac{e^x + e^{-x}}{2}[/tex]

We make:

[tex]f(-x) = \frac{e^{-x} + e^{-(-x)}}{2}[/tex]

Rewriting the function we have

[tex]f(-x) = \frac{e^{-x} + e^{x}}{2} = \frac{e^{x} + e^{-x}}{2}\\\\f(-x) = f(x)[/tex]

Finally, the function has symmetry with respect to the y axis.

Answer:

62.5

Step-by-step explanation:

By dividing 50 by 10 and 10 by 2 we can find that r, or the common ratio is 1/5, meaning that this series converges, so it is solvable. The formula for a convergent series is [tex]\frac{a_{1}}{1-r}[/tex]. By plugging in 1/5 for r and 50 for  [tex]a_{1}[/tex] we can find that the sum of this infinite series is 62.5

x + x +1 + x +2 + x + 3 >= 244

=》 4x + 6 >= 244

=》 4x >= 238

=》 x >= 238/4 >= 59.5

since x is an integer...least value of x is 60

The least possible even integer is 58

Let's let x be an even integer. The next three would be shown by x+2, x+4 x+6 so now we can add all these to equal 244. Shown with an equation would look like:

x + x+2 + x+4 + x+6 = 244

Combine like terms will be:

4x+12=244

Subtract 12 from both sides we will get

4x=232

Now Divide each side by 4

x=58

So now put x in the above equation and we get  the numbers

x=58,

x+2= 60

X+4 =62

x+6= 64

The least one is 58

Choice D is correct

Step-by-step explanation:

The eccentricity of the conic section is 1, implying we are looking at a parabola. Parabolas are the only conic sections with an eccentricity of 1.

Next, the directrix of this parabola is located at x = 4. This implies that the parabola opens towards the left and thus the denominator of its polar equation contains a positive cosine function.

Finally, the value of k in the numerator is simply the product of the eccentricity and the absolute value of the directrix;

k = 1*4 = 4

This polar equation is given by alternative D.

The surface are of the prism will be the area of a each side added together. The work would look like this:

SA = 2[(l×h)+(l×b)+(b×h)]

SA = 2(lh+lb+bh)

But if you multiply each dimension by 5, the area becomes

SA = 2[(5l×5h)+(5l×5b)+(5b×5h)]

SA = 2(5²lh+5²lb+5²bh)

SA = 5²×2(lh+lb+bh)

SA = 5²area

Since 5² = 25, then the the surface area is multiplied in size by 25.

The discount is $37.50 and the sale price of the table is $212.50.

We have to calculate the discount and sale price

Discount

Discount amount =

Original price * Discount percentage

Discount amount = $250 * 15%

= $250 * 0.15

= $37.50

Sale price

Sale price = Original price - Discount amount

Sale price = $250 - $37.50

= $212.50

For this case we must find the area of a scalene triangle (different sides) by means of Heron's formula:

[tex]S = \sqrt {p (p-a) (p-b) (p-c)}[/tex]

Where:

S: It's the area

p: It is the semiperimeter

a, b, c: They are the sides:

[tex]p = \frac {a + b + c} {2}\\p = \frac {25 + 13 + 17} {2}\\p = 27.5 \ units[/tex]

So:

[tex]S = \sqrt {27.5 (27.5-25) (27.5-13) (27.5-17)}\\S = \sqrt {10467.1875}\\S = 102.309 \ units ^ 2[/tex]

[tex]\frac{48}{1369}[/tex]

Step-by-step explanation:

A bag contains 4 green marbles, 6 red marbles, 14 orange marbles, 5 brown marbles, and 8 blue marbles. You choose a marble, replace it, and choose again. Total marbles = 37 marbles

Probability (choosing red) = number of red marbles / total marbles

= 6/37

Red is replaces so total marbles again becomes 37

P( choosing blue)= 8/37

P(red, then blue)= [tex]\frac{6}{37} * \frac{8}{37} = \frac{48}{1369}[/tex]

Answer:

Option c

Step-by-step explanation:

We have two matrices, matrix A and matrix B.

Before doing the addition of matrices, we must multiply the matrix A by the scalar -7 and then multiply the matrix B by the scalar -6.

The multiplication of a matrix A by a scalar c, is done by multiplying all the elements of matrix A by the value c.

So

[tex]-7A = \left[\begin{array}{ccc}70&-70&-56\\14&7&-35\\28&-56&42\end{array}\right]\\\\\\-6B =\left[\begin{array}{ccc}-30&-36&24\\-60&36&60\\54&-6&-60\end{array}\right][/tex]

Now we add both matrices.

The sum of the matrices is done by adding each term [tex]a_{mn}[/tex] with each term [tex]b_{mn}[/tex]

For example: (70 - 40) , (-70 + (-36)), ...,    

Then:

[tex]-7A + (-6B) = \left[\begin{array}{ccc}40&-106&-32\\-46&43&25\\82&-62&-18\end{array}\right][/tex]

You can see that each term is twice the previous one, with inverted sign.

You double a number by multiplying it by two, and you change its sign by multiplying it by -1.

So, you multiply each term by 2 and by -1, which results in a multiplication by -2.

Since we start with 3, the terms are

[tex]a_1 = 3[/tex]

[tex]a_2 = 3\cdot (-2) = -6[/tex]

[tex]a_3 = -6\cdot (-2) = 12[/tex]

and so on. So, the general term is

[tex]a_n = 3\cdot(-2)^{n-1}[/tex]

=============================================

Explanation:

Start with the first equation. We'll plug in y = 2x+2

3x - y = 3

3x - ( y ) = 3

3x - ( 2x+2 ) = 3 ..... replace y with 2x+2

3x - 2x - 2 = 3 ..... distribute the negative through to all terms inside

x-2 = 3  ............ combine like terms

x-2+2 = 3+2 .... add 2 to both sides

x = 5

Use this x value to find the value of y. The easiest equation to use is the one in which y is already isolated for us

y = 2x+2

y = 2*5+2 ..... replace x with 5

y = 10+2

y = 12

Though we can use the other equation as well

3x-y = 3

3*5-y = 3 .... replace x with 5

15 - y = 3

15-y-15 = 3-15 ..... subtract 15 from both sides

-y = -12

y = 12 ..... multiply both sides by -1, or change the signs of both sides

We get the same result for y.

The solution is (x,y) = (5,12) meaning that the graphs of the two original equations cross at this point.

It’s 5 & 12. Just substitute them in and boom!

Answer:

f is not  defined at x = 3 ⇒ answer (b)

Step-by-step explanation:

∵ f(x) = x² - x - 6/x² - 9 is a rational function

∴ It will be undefined at the values of x of the denominator

∵ The denominator is x² - 9

∵ x² - 9 = 0 ⇒ x² = 9 ⇒ x = ±√9

∴ x = ± 3

∴ f(x) can not be defined at x = 3

∴ The f(x) can not be continuous at x = 3

∴ The answer is (b)

Answer:

b. f is not defined at x=3

Step-by-step explanation:

The given function is

[tex]f(x)=\frac{x^2-x-6}{x^2-9}[/tex]

One of the conditions for continuity is that; the function must be defined at [tex]x=a[/tex]

If we plug in [tex]x=3[/tex], we obtain;

[tex]f(x)=\frac{3^2-3-6}{3^2-9}[/tex]

[tex]f(x)=\frac{9-3-6}{9-9}[/tex]

[tex]f(x)=\frac{0}{0}[/tex]

Since the function is not defined at x=3, it is not also continuous at x=3

Where, r is the radius of the cylinder,

And, h is the height of the cylinder,

Here, r = 3 feet,

h = 5 feet,

Hence, the volume of the given cylinder is,

[tex]V=\pi (3)^2 (5)[/tex]

Answer:

Option A

Step-by-step explanation:

A relation can be defined as a function if there is only one output for each input.

In this case, the output is the cost of the fabric and the input is the number of yards of fabric.

Then, for each number of yards of fabric there will be a cost. But there will not be two different costs (outputs) for the same number of fabric yards (entrance)

Then the answer is the Option A: Yes, because one imput (number of yards of fabric) will always have the same output (costs)

We will need to picture for this.
