Answer:

A.) 40(t) = E

B.) 520

Step-by-step explanation:

t is for time, E is the total, H is the hourly rate.

plug in the numbers to get 40(13) = h and solve for H and you get 520

-- Brainliest answer is much appreciated! :)

An equation is formed of two equal expressions. Mary's earnings after tutoring for 13 hours is $520.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that for each hour that Mary tutors she earns 40 dollars. Therefore, the equation to find marys earnings after tutoring for H hours can be written as,

Earnings = Hourly rate of tutoring × Number of hours

E = 40 × H

E = 40H

Now, Mary's earnings after tutoring for 13 hours will be,

E = 40(13)

E = 520

Hence, Mary's earnings after tutoring for 13 hours is $520.

Answer:

Its A) 23

Step-by-step explanation:

Its right, trust me

The possible value of the third side of the triangle is 23.

The range of third side c when two sides a and b of a triangle are known is given by the inequality:

[tex]a-b < c < a+b[/tex]

It is given that:

a =15

b = 9

So, by the triangle inequality

[tex]15-9 < c < 15+9[/tex]

6 <c <24

The third side will take the value between 6 and 24.

so, the possible value of the third side of the triangle i.e. c is 23.

Therefore, the possible value of the third side of the triangle is 23.

Line DF is parallel

In triangle ABC with midpoints D, E, and F on sides AB, BC, AC, respectively, segment DF is parallel to BC based on the Midline Theorem

In triangle ABC, if D, E, and F are the midpoints of sides AB, BC, and AC, respectively, then the line segment DE is parallel to BC as per the Midline Theorem.

This theorem states that if a line segment connects the midpoints of two sides of a triangle, that segment is parallel to (and half the length of) the third side of the triangle.

Considering our given scenario, the midpoints of AB and AC are D and F and the line segment formed is DF.

Following the Midline Theorem, this segment DF would be parallel to the third side of the triangle, i.e., BC.

So, the answer to the question 'which segment is parallel to BC?' is DF.

The residual value is -8

A residual value is the difference between the observed y-value and the predicted y-value( from the regression equation ) .

Here, the given regression equation of the line,

y = 5.2 x +18

Thus, for x = 10, the predicted value of

y = (5.2 × 10) +18

y = 52 + 18

y = 70

Now, by the given question,

For x = 10, the observed value of y = 62,

Hence, the residual for 10 = Observed value of y for 10 - Predicted value of y for 10

= 62 - 70

Final answer:

By setting up a system of equations based on the provided information and solving them, we can determine that there were 5 adults in the group that attended the circus.

Explanation:

To determine how many adults were in the group at the circus, let's use variables to represent the number of students and adults in the group. Let x be the number of students and y be the number of adults. We know there are a total of 9 people, so we have the equation:

x + y = 9

The total cost for all tickets is $60, and considering the cost for students is $5 and for adults is $8, we have the equation:

5x + 8y = 60

We now have a system of equations that can be solved using the substitution or elimination method. If we solve for x in the first equation (x = 9 - y) and substitute into the second equation:

5(9 - y) + 8y = 60

45 - 5y + 8y = 60

3y = 15

y = 15 / 3

y = 5

There are 5 adults in the group. Now, we can find the number of students by substituting y back into the first equation:

x + 5 = 9

x = 9 - 5

x = 4

So, there are 4 students in the group.

Answer:

[tex]f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})[/tex]

Step-by-step explanation:

The given function is

[tex]y=\frac{\pi}{2}+\sin x[/tex]

To find the inverse of this function, we interchange x and y.

[tex]x=\frac{\pi}{2}+\sin y[/tex]

we now solve for y.

[tex]x-\frac{\pi}{2}=\sin y[/tex]

Take the sine inverse of both sides to obtain;

[tex]\sin ^{-1}(x-\frac{\pi}{2})=y[/tex]

Hence the inverse of the given function is;

[tex]f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})[/tex]

where [tex]\frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1[/tex]

Answer:

Step-by-step explanation:

Answer:

the answers are interquartile range and mean absolute deviation

Step-by-step explanation:

In statistics, measures of variability are Interquartile Range and Mean Absolute Deviation, which indicate the degree of spread in a data set. However, the Mean is a measure of central tendency, not variability.

In the context of statistics, measures of variability are statistical data that highlight the degree of the spread in a data set. These are measures that can help us to identify how much the values in the data set differ from their mean value. Out of the options provided, II. Interquartile Range and III. Mean Absolute Deviation can be classified as measures of variability.

The Interquartile Range (IQR) is a measure of statistical dispersion and is calculated as the difference between the 75th and 25th percentiles. It’s the range within which the center half of a data set lies. The Mean Absolute Deviation (MAD) is the average distance between each data value and the mean.

However, I. Mean is not a measure of variability but rather a measure of central tendency. It helps to identify the central point or typical value of a data set but does not represent the dispersion of data points.

Answer:

A)$1667 in 7.5%, $833 in 6%

Step-by-step explanation:

You need to average 7% interest.

initial investment = $2500

7% of $2500 = [tex]\frac{7}{100}[/tex] × 2500  ⇒ (0.07 ) × (2500) ⇒ $175

so the combined interest from both accounts should be $175

Checking options:

A)$1667 in 7.5%, $833 in 6%                      ∵ 7.5 % = 0.075  

(1667 × 0.075) + (833 × 0.06)                             6 % = 0.06

125.025 + 49.98 ⇒ 175.005

B) $1833 in 7.5%, $667 in 6%

(1833 × 0.075) + (667 × 0.06)

137.475 + 40.02 ⇒ 177.495

C)$667 in 7.5%, $1833 in 6%

(667 × 0.075) + (1833 × 0.06)

50.025 + 109.98 ⇒ 160.005

D)$833 in 7.5%, $1667 in 6%

(833 × 0.075) + (1667 × 0.06)

62.475 + 100.02 ⇒ 162.495

Step-by-step explanation:

Answer:

Option A. $19,500

Step-by-step explanation:

A smart phone manufacturer uses 10 ounces of gold circuitry to make 5,200 smartphones.

We will solve this problem by unitary method.

In 5200 smartphones use of gold = 10 ounces

in 1 smartphone use of gold = [tex]\frac{10}{5200}[/tex] = 0.001923 ounces

In 7,800 smartphones, use of gold = 0.001923 × 7800 = 14.999 ounces rounded to 15 ounces of gold

Last month the value of 1 ounce gold is $1,300

The value of 15 ounces = 1,300 × 15 =  $19,500

The value of gold used last month is $19,500.

Answer:

C, (x,y) → (x + 8, y - 3)

Step-by-step explanation:

we can locate one point on the shape and use that as a reference point to see where it goes.

ABCD is the original shape, while A'B'C'D' is the translated shape

we start at ABCD, for this shape i picked the point B to follow

we count how many units the point B goes in order to get to B'. we start on the x axis, and see that it goes 8 units to the right. this is an increase, as its rising in value

from there, we follow the y axis, moving 3 units down. this is a decrease, as we are going 3 units down

so according to what we have moved in order to get from B to B', we moved 8 to the right so we have x + 8, with x being the x-coordinate the point was previously on. we have moved 3 units down to get from B to B', which is y - 3, with y being the y-coordinate the point was on previously

the answer to this is C, (x,y) → (x + 8, y - 3)
