Answer:

The time a student learns mathematics is important for their score

Step-by-step explanation:

Observe the boxes diagrams. Where the horizontal axis represents the score obtained by the students in the test.

The vertical lines that divide the boxes in two represent the value of the median.

The median is the value that divides 50% of the data.

For the class of the morning the value of the median is 50 points, with a maximum value of 80 and a minimum value of 10.

For the afternoon class, the median value is 65 points with a minimum value of 30 and a maximum value of 100.

This indicates that in general, the highest number of high scores were obtained in the afternoon class.

Therefore it can be said that the time a student learns mathematics is important for their  score

Answer Sorry if this is too late but the answer is yes because the median test score of the afternoon class is 15 points above the morning class other wise the first option

Step-by-step explanation:

Kyra sold a car that cost $26,500

1325 = 0.05x

1) 0.05x = 1325

2) Divide both sides by 0.05 -—> 0.05x/0.05 = 1325/0.05

3) x = 26,500

Final answer:

Kyra's commission of $1,325, which is 5% of the car's cost, leads us to calculate the cost of the car by dividing the commission by the commission rate, resulting in a car cost of $26,500.

Explanation:

Kyra receives a 5% commission on every car she sells. We are given that her commission on the last car she sold was $1,325. To find the cost of the car, we use the formula:

Commission = (Commission Rate) × (Cost of the Car)

Therefore,

Cost of the Car = Commission ÷ Commission Rate

Cost of the Car = $1,325 ÷ 0.05

Cost of the Car = $26,500

So, the car that Kyra sold was worth $26,500.

Step-by-step explanation:

5! = 5*4*3*2*1

3! = 3*2*1

5!/3! = 5*4*3*2*1

           ----------------

           3*2*1

Canceling common factors

For this case we have that by definition, the factorial of a number is the product of the "n" consvutive factors from n to 1. The factors are in descending order, that is:

[tex]n! = n (n-1) (n-2) ... 3 * 2 * 1[/tex]

Then, we have the following expression:

[tex]\frac {5!} {3!}[/tex]

Applying the definition we have:

[tex]\frac {5!} {3!} = \frac {5 * 4 * 3 * 2 * 1} {3 * 2 * 1} = \frac {120} {6} = 20[/tex]

Answer:

1. 48 square feet

2. 308 square feet

Step-by-step explanation:

1.

The entry terrace is shaped as a trapezoid and the area of a trapezoid is given as:

Area of Trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

Where

b_1 and b_2 are the 2 parallel bases

and h is the perpendicular height

From the diagram, we see that the 2 bases are 16 and 8 and height is 4.

Plugging into the formula, we get:

Area of Entry Terrace = [tex]\frac{1}{2}(b_1+b_2)h=\frac{1}{2}(16+8)*4=\frac{1}{2}(24)(4)=48[/tex]

2.

The total area comprises of the area of entry terrace + playroom + back porch.

The area of the back porch is 6 * 6 = 36 (it is shaped like a square and square has area of side * side)

The area of the playroom is 14 * 16 = 224 (it is a rectangle and rectangle has area of base * height)

Total area of treehouse = 48 + 36 + 224 = 308 square feet

Answer:

The entry terrace has an area of

48

square feet. The total area of the tree house including the entrance, porch, and side deck is

350

square feet.

Answer:

After 3 hours, both the airplanes are at a distance of 938.9 meters from each other.

Step-by-step explanation:

Speed of plane A = 275 mph

Speed of plane B = 375 mph

Angle between their flight path = Ф = 55°

Let their paths after 3 hours make a triangle.

Path of plane A is side 'a' = 275*3 = 825

Path of plane B is side 'b' = 375*3 = 1125

Distance between both planes after 3 hours = side 'c'

Here, we have two sides and one angle of the triangle.

We can find the third side using the law of cosines which is given as:

c² = a² + b² - 2ab*cosФ

c² = 825² + 1125² - 2(825)(1125)(cos(55°))

c² = 680625 + 1265625 - 1064745             where cos(55°) = 0.5736

c² = 881,505

c = √881,505

c = 938.9

c = 938.9 meters

Answer:

x = 39.1

Step-by-step explanation:

Points to remember

Mean of a data set is given by

Mean = (sum of data set)/Total number of data

To find the value of x

It is given a data set

31.7, 42.8, 26.4, x

Mean = 35

Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x

(100.9 + x)/4 = 35

100.9 + x = 35 * 4 = 140

x = 140 - 100.9 = 39.1

Therefore x = 39.1

ANSWER

P(x)=2(f+g)(x)

EXPLANATION

The perimeter of a rectangle is calculated using the formula:

P=2(l+w)

From the table

The length is f(x)=x+3

The width is g(x)=x+2

This implies that the perimeter is

P(x)=2(f(x)+g(x))

This is the same as

P(x)=2(f+g)(x)

Answer: If you take the $8 service fee away from 38 you get 30. Then do 30/.12 and you get 250. To check it just do 250 x .12 and you'll get 30.

The answer is 250 minutes

Step-by-step explanation:

To find the number of minutes the customer used the phone, solve the equation c = 0.12m + 8 where c is the total cost for one month and m is the number of minutes used. Given that the customer's bill for the month is $38.00, substitute this value and solve for m. The customer used the phone for 250 minutes.

To find the number of minutes the customer used the phone, we can solve the equation

c = 0.12m + 8

where c is the total cost for one month and m is the number of minutes used.

Given that the customer's bill for the month is $38.00, we can substitute this value for c in the equation:

$38.00 = 0.12m + 8

Next, we can subtract 8 from both sides of the equation and then divide by 0.12 to isolate the variable m:

$38.00 - 8 = 0.12m

$30.00 = 0.12m

m = $30.00 / 0.12

m = 250 minutes

So, the customer used the phone for 250 minutes.

Final answer:

An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. In this case, the recursive formula for the arithmetic sequence is A1 = 5 and An = An-1 - 4.

Explanation:

An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. In this case, the recursive formula for the arithmetic sequence is A1 = 5 and An = An-1 - 4. Let's find some terms in this sequence:

A1 = 5

A2 = A1 - 4 = 5 - 4 = 1

A3 = A2 - 4 = 1 - 4 = -3

A4 = A3 - 4 = -3 - 4 = -7

...

So the first few terms in this arithmetic sequence are 5, 1, -3, -7, ...

Answer:

The correct answer option is A. y = 5x + 29.

Step-by-step explanation:

We are given the following equation of a line and we are to identify the equation of a line parallel to this line which passes through (-6, -1), in slope intercept form:

[tex]y = 5x+2[/tex]

Parallel lines have same slope, so the slope of this line will be 5.

Finding the y-intercept using the standard equation of line.

[tex]y=mx+c[/tex]

[tex]-1=5(-6)+c[/tex]

[tex]c=29[/tex]

Therefore, our equation will be:

[tex]y=5x+29[/tex]

The answer is:

The equation of the line that it's parallalel to the given line and passes through the point (-6,-1) will be:

A.

[tex]y=5x+29[/tex]

To find an equation in slope-intercept form for the linea paralallel to the given line, we must guarantee that the new line will have the same slope of the given line.

We are given the line:

[tex]y=5x+2[/tex]

Where its slope is equal to 5

[tex]m=5[/tex]

and the point (-6,-1)

The slopte-intercept form of a line, is given by the following equation:

[tex]y=mx+b[/tex]

Then, we know that the line that we are looking for, will have a slope equal to 5, so:

[tex]y=5x+b[/tex]

Now, substituting the given point in order to find "b", we have:

[tex]y=5x+b[/tex]

[tex]-1=5*(-6)+b[/tex]

[tex]-1=-30+b[/tex]

[tex]b=-1+30=29[/tex]

Hence, we have that the equation of the line that it's parallalel to the given line and passes through the point (-6,-1) will be:

[tex]y=5x+29[/tex]

Answer:

Step-by-step explanation:

The formula of an area of a parallelogram:

[tex]A=bh[/tex]

b - base

h - height

We have

[tex]b_1=36,\ h_1=24\\\\b_2=27,\ h_2=h[/tex]

Calculate the area:

[tex]A=(36)(24)=864[/tex]

[tex](27)(h)=864[/tex]           divide both sides by 27

[tex]h=32[/tex]

The highest peak is in the middle and both sides of it are fairly similar, so this would be a bell shaped distribution.

Answer: [tex]x[/tex]≈[tex]0.732[/tex]

Step-by-step explanation:

You need to find the value of the variable "x".

To solve for "x" you need to apply the following property of logarithms:

[tex]log(m)^n=nlog(m)[/tex]

Apply logarithm on both sides of the equation:

[tex]90^x=27\\\\log(90)^x=log(27)[/tex]

Now, applying the property mentioned before, you can rewrite the equation in this form:

[tex]xlog(90)=log(27)[/tex]

Finally, you can apply the Division property of equality, which states that:  

 [tex]If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}[/tex]

Therefore, you need to divide both sides of the equation by [tex]log(90)[/tex]. Finally, you get:

[tex]\frac{xlog(90)}{log(90)}=\frac{log(27)}{log(90)}\\\\x=\frac{log(27)}{log(90)}[/tex]

[tex]x[/tex]≈[tex]0.732[/tex]

Answer:

The probability is 0.0015

Step-by-step explanation:

We know that the mean [tex]\mu[/tex] is:

[tex]\mu=6:30\ p.m[/tex]

The standard deviation [tex]\sigma[/tex] is:

[tex]\sigma=0:15\ minutes[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

We seek to find

[tex]P(x>7:15\ p.m.)[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

[tex]Z=\frac{7:15-6:30}{0:15}[/tex]

[tex]Z=\frac{0:45}{0:15}[/tex]

[tex]Z=3[/tex]

The score of Z = 3 means that 7:15 p.m. is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

So

[tex]P(x>7:15\ p.m.)=P(Z>3)=0.0015[/tex]

3.73 in expanded form

3 + 0.7+ 0.03

Final answer:

The number 3.73 in expanded form is written as 3 + 0.7 + 0.03, showing the value of each digit according to its place value.

Explanation:

The question is asking to write the number 3.73 in expanded form which is a way of writing numbers to show the value of each digit. When a number is written in expanded form, we break apart the number by each digit's place value, isolating each digit to represent the total sum of each part.

So, for the number 3.73, we can expand it as follows:

Now, combining these values together, we can write 3.73 in expanded form as:

3 + 0.7 + 0.03

Answer:

(g+f)(x)=(2^x+x-3)^(1/2)

Step-by-step explanation:

Given  

f(x)= 2^(x/2)

And

g(x)= √(x-3)

We have to find (g+f)(x)

In order to find (g+f)(x), both the functions are added and simplified.

So,

(g+f)(x)= √(x-3)+2^(x/2)  

The power x/2 can be written as a product of x*(1/2)

(g+f)(x)= √(x-3)+(2)^(1/2*x)

We also know that square root dissolves into power ½

(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)

We can see that power ½ is common in both functions so taking it out

(g+f)(x)=(x-3+2^x)^(1/2)

Arranging the terms

(g+f)(x)=(2^x+x-3)^(1/2)  ..

Answer:
