Answer:

Mean absolute deviation = 1.6.

Step-by-step explanation:

The  mean  =  (4+4+ 6+ 6+ 7+ 8+ 8 + 8 +9+ 10) / 10

= 7.

List the differences from the mean:

4 - 7 = -3

-3

-1

Sum of the absolute value of the difference

=  3 + 3 + 1 + 1 + 0 + 1 + 1 + 1 + 2 + 3

= 16.

So the Mean Absolute deviation = 16 / 10 = 1.6.

The big pine tree is approximately 64 feet tall, based on Trevor's estimates of its shadow and the building's shadow.

To find the height of the big pine tree, we can use proportions based on the relationship between the lengths of the shadows and the heights of the objects.

Let's denote:

[tex]- \( S_t \)[/tex] as the length of the shadow of the tree,

[tex]- \( H_t \)[/tex] as the height of the tree,

[tex]- \( S_b \)[/tex] as the length of the shadow of the building, and

[tex]- \( H_b \)[/tex] as the height of the building.

From Trevor's estimates:

[tex]- \( S_t = 48 \)[/tex] feet,

[tex]- \( S_b = 18 \)[/tex] feet, and

[tex]- \( H_b = 24 \)[/tex] feet.

We can set up a proportion to solve for [tex]\( H_t \):[/tex]

[tex]\[ \frac{H_t}{S_t} = \frac{H_b}{S_b} \][/tex]

Substituting the given values:

[tex]\[ \frac{H_t}{48} = \frac{24}{18} \][/tex]

Cross-multiplying:

[tex]\[ 18 \times H_t = 24 \times 48 \][/tex]

[tex]\[ 18H_t = 1152 \][/tex]

[tex]\[ H_t = \frac{1152}{18} \][/tex]

[tex]\[ H_t = 64 \][/tex]

Therefore, the big pine tree is approximately 64 feet tall.

The complete question is:

EVALUATE Trevor took big steps to find the length of the shadow of the big pine tree in front of the school. He estimated that the shadow was 16 yards long, or about 48 feet. He also stepped off the shadow cast by the two-story school building and estimated that its shadow was 18 feet long. Trevor thinks the building is 24 feet tall. About how many feet tall is the big pine tree?

Answer:

The area of the rectangle is given by the expression "20x² - 10x - 30".

Step-by-step explanation:

The area of a rectangle is given by the product of it's dimensions. This is shown in the formula bellow:

area = width*height

In this case the width is an expression, so we need to multiply the numeric part of each mnemonic

area = 5*(4x² - 2x - 6)

area = 20x² - 10x - 30

The area of the rectangle is given by the expression "20x² - 10x - 30".

The equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].

Step-by-step explanation:

Given,

x = 8t+3

y= 9t+3

First, convert both the equations in terms of t for comparison.

x = 8t + 3

x - 3 = 8t

t = [tex]\frac{x-3}{8}[/tex]

Similarly,

y = 9t + 3

y - 3 = 9t

t = [tex]\frac{y-3}{9}[/tex]

Now, comparing both equations

[tex]\frac{x-3}{8}[/tex] =  [tex]\frac{y-3}{9}[/tex]

9x -27 = 8y -24

9x - 3 = 8y

or

y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex]

Hence, the equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].

Answer:

x=2, y=12

STEP BY STEP-

Replace the Y in 2x+3y=40 for X+10, because y=x+10. You now have 2x+3(x+10)=40. Now multiply the X and the 10 by 3, so you have 2x+3x+30=40. Combine like terms to get 5x+30=40. Subtract the 30 on both sides so you get 5x=10. Divide by 5 and that gives you the solution for X (2). Then, plug 2 in for X in the equation y=x+10. You now have Y=2+10. Combine like terms and you get 12, so Y=12.

Sorry that I'm so bad at explaining things

Final answer:

Substitute y = x + 10 into 2x + 3y = 40, simplify to 5x = 10, solve for x, then substitute x into the second equation to find y. The solution is x = 2 and y = 12.

Explanation:

The solution to the system of equations 2x + 3y = 40 and y = x + 10 can be found by substituting the second equation into the first. This is a common method for solving systems of linear equations, which involves elimination and substitution. We substitute y from the second equation into the first to get 2x + 3(x + 10) = 40, which simplifies to 2x + 3x + 30 = 40. After combining like terms, we have 5x = 10, which gives us x = 2. We then substitute x back into the second equation to find y. If x = 2, then y = 2 + 10, which means y = 12.

5 hours.. 140 cupcakes. You divide the amount by the hours, showing you that 28 cupcakes per hour is the answer.

Answer: Per hour, Robin makes 28 cupcakes.

Step-by-step explanation:

To find the unit rate, you are essentially finding one of something. In this case you were finding out how many cupcakes you could make in ONE hour. To do this, you had to look at the information you already had. You knew that 140 cupcakes were made in 5 hours. So the fraction is 140/5. If you divide the bottom and top by five, your new equation would be 28/1.

Given : Lily provider a loan of $2500 to David that had an annual interest rate of 4.6%.

To find : The balance after 5 years if it compounded yearly ?

Solution :

Using compound interest formula,

Step-by-step explanation:

The positive difference between the maximums of functions g and f is 2

From the question, we have the following parameters that can be used in our computation:

f(x) = -x² + 4x + 6

So, the x of the vertex is

x = -4/2 * -1

x = 2

So, the maximum is

Max = -2² + 4(2) + 6

Max = 10

From the graoh, we have

Max = 12

So, we have

Difference = 12 - 10

Difference = 2

Hence, the positive difference is 2

Answer:

The circumference of the circle in terms of π is 8π.

If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.

If π is approximated to 3.14, the circumference of the circle is 25.12 cm.

Step-by-step explanation:

The circumference of the circle = 2*π*r

r = radius

r = d/2

r= 8cm/2 = 4cm

π = 3.14

The circumference of the circle = 2π(4)= 8π , so we have:

The circumference of the circle in terms of π is 8π.

Using pi = 22/7, we have:

The circumference of the circle = 2* 22/7 * 4 = 8* 22/7 = 25.14 cm, so we have:

If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.

Using pi = 3.14, we have:

The circumference of the circle = 2* 3.14 * 4 = 8* 3.14 = 25.12 cm, so we have:

The volume for the triangular prism is 40.5 cubic inches.

Step-by-step explanation:

Given:

The base of a triangular prism has an area of 18 square inches .  

And the height is 4.5 inches.

Now, to get the triangular prism volume.

The base area = 18 square inches.

Height = 4.5 inches.

Now, to get the volume of prism we put formula:

[tex]Volume=\frac{1}{2} \times base\ area\times height\\\\Volume=\frac{1}{2} \times 18\times 4.5\\\\Volume=40.5\ cubic\ inches.[/tex]

Therefore, the volume for the triangular prism is 40.5 cubic inches.

The volume of the triangular prism is 81 cubic inches.

To calculate the volume of a triangular prism, you can use the formula:
Volume = Base Area * Height
Given:
- The base area of the triangular prism is 18 square inches.
- The height of the prism is 4.5 inches.
Plug these values into the formula:
Volume = 18 square inches * 4.5 inches
Multiply these values:
Volume = 81 cubic inches

So, the volume of the triangular prism is 81 cubic inches.

Step-by-step explanation:

16.8 gallons of water is equal to 67.2 quarts and 134.4 pints.

Final answer:

To convert gallons to quarts, multiply the number of gallons by 4, which gives us 67.2 quarts (Option C). To convert gallons to pints, multiply the number of gallons by 8, resulting in 134.4 pints (Option C).

Explanation:

The question pertains to converting units of volume from gallons to quarts and pints. Given that the aquarium has a capacity of 16.8 gallons and knowing that there are 4 quarts in a gallon, we multiply 16.8 by 4 to find the capacity in quarts:

16.8 gallons × 4 quarts/gallon = 67.2 quarts

Next, to find the number of pints, we consider that there are 8 pints in a gallon (since each quart is equivalent to 2 pints, and there are 4 quarts in a gallon). Thus, we multiply:

16.8 gallons × 8 pints/gallon = 134.4 pints
