Please Help! I got an answer, but I think it's wrong.

Answer:

252 square yards.

Step-by-step explanation:

To find the square yardage of the roof of the building, we need to calculate the area of the shaded triangle and the area of the shaded rectangle.

First, let's calculate the area of the triangle:

Base of the triangle = 6 divisions = 6 x 2 yards = 12 yards

Height of the triangle = 5 divisions = 5 x 2 yards = 10 yards

Area of the triangle = (1/2) x base x height

= (1/2) x 12 yards x 10 yards

= 60 square yards

Next, let's calculate the area of the rectangle:

Length of the rectangle = 8 divisions = 8 x 2 yards = 16 yards

Width of the rectangle = 6 divisions = 6 x 2 yards = 12 yards

Area of the rectangle = length x width

= 16 yards x 12 yards

= 192 square yards

To find the square yardage of the roof, we add the area of the triangle and the area of the rectangle:

Total area = 60 square yards + 192 square yards

Step-by-step explanation:

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

This is most probably a trick question because when you solve the mean and median of both you can clearly see that their answers are averages are correct, even the rounding of decimals.

Answer:

  Michael is wrong

Step-by-step explanation:

You want to know which student has misunderstood their grade computation, given the mean and median scores shown.

The mean of the test grades is their sum, divided by their number. The values shown for the mean grades are correct.

"Average" is another name for "mean." Thus the students' grade average will be the value of their mean grade, not their median grade.

Michael in incorrect in assuming that his median grade of 70% earns him a C in the class.

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

(x, y) = (4, 11).

Step-by-step explanation:

We have two equations:

3(y-2x) = 9

x - 4 = 0

From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:

3(y-2x) = 9

3(y-2(4)) = 9 (substitute x = 4)

3(y-8) = 9

3y - 24 = 9

3y = 33

y = 11

Therefore, the solution to the system of equations is (x, y) = (4, 11).

Answer:

-12.5, DECREASE

Step-by-step explanation:

Jen usually gets 8 hours of sleep. Last night she got 7 hours of sleep. then the Percent of Change is Decrease by 12.5%.

Percent of change is a way to measure the relative difference between two values.

In this case, we're comparing Jen's usual sleep time (8 hours) to her sleep time last night (7 hours).

To calculate the percent of change, we use the formula:

\(\[ \text{Percent Change} = \frac{\text{New Value - Old Value}}{\text{Old Value}} \times 100 \]\)

Plugging in the values:

\(\[ \text{Percent Change} = \frac{7 - 8}{8} \times 100 \]\)

\(\[ \text{Percent Change} = -\frac{1}{8} \times 100 = -12.5\% \]\)

The negative sign indicates a decrease, and the magnitude of 12.5% represents how much Jen's sleep time decreased compared to her usual.

In this context, the percent of change tells us that Jen's sleep time decreased by 12.5% from her usual 8 hours.

This means she got less sleep than usual last night.

The negative sign signifies a decrease, and the magnitude (12.5%) quantifies the extent of this decrease.
