A music teacher asked 23 students in the band how many hours they practiced playing their instrument each week. The results are shown in the dot plot. Which statement best describes the data?

Answer:

0%

Step-by-step explanation:

ITS A CUBE BRUH!!!!

The price per hour for the service business, based on a 75% profit with a cost per hour of $30, is $52.50.

To calculate the price per hour for a service business with 75% profit and a cost per hour of $30, we need to take into account the desired profit margin, which is 75%. This means that the total price per hour should be 175% of the cost per hour, since 100% covers the cost and 75% is the desired profit.

To calculate the total price per hour, we can multiply the cost per hour by 1.75 (175%). This gives us a total price per hour of $52.50. This means that for every hour of service provided, the business will charge $52.50, with $30 covering the cost of providing the service, and $22.50 (75% of $30) being the profit margin.

It is important to note that the price per hour may vary depending on factors such as competition, market demand, and value proposition. It is recommended to conduct a thorough market analysis and consider these factors when determining the pricing strategy for a service business.

Answer:

c = \(\frac{25}{4}\)

Step-by-step explanation:

To make a perfect square

add ( half the coefficient of the x- term )² to x² + 5x

x² + 5x + (\(\frac{5}{2}\) )²

= x² + 5x + \(\frac{25}{4}\)

= (x + \(\frac{5}{2}\) )² ← a perfect square

Answer:

x=5 and y=7

Step-by-step explanation:

x + 2 = y (equation 1)

x + 23 = 4y (equation 2)

(equation 2) - (equation 1)

This gives,21 = 3y

y = 21/3

y = 7.

Put y = 7 into equation 1 to find x

x + 2 = 7

x = 7 - 2

x = 5.

Answer:  A

Step-by-step explanation:

When multiplying: Numbers multiply with numbers and for the x's, add the exponents

If there is no exponent, you can assume an imaginary 1 is the exponent

2x⁴ (3x³ − x² + 4x)

= 6x⁷ -2x⁶ + 8x⁵

Answer:

A. \(6x^{7} - 2x^{6} + 8x^{5}\)

Label the parts of the expression:

Outside the parentheses = \(2x^{4}\)

Inside parentheses = \(3x^{3} -x^{2} + 4x\)

You must distribute what is outside the parentheses with all the values inside the parentheses. Distribution means that you multiply what is outside the parentheses with each value inside the parentheses

\(2x^{4}\) × \(3x^{3}\)

\(2x^{4}\) × \(-x^{2}\)

\(2x^{4}\) × \(4x\)

First, multiply the whole numbers of each value before the variables

2 x 3 = 6

2 x -1 = -2

2 x 4 = 8

Now you have:

6\(x^{4}x^{3}\)

-2\(x^{4}x^{2}\)

8\(x^{4} x\)

When you multiply exponents together, you multiply the bases as normal and add the exponents together

\(6x^{4+3}\) = \(6x^{7}\)

\(-2x^{4+2}\) = \(-2x^{6}\)

\(8x^{4+1}\) = \(8x^{5}\)

Put the numbers given above into an expression:

\(6x^{7} -2x^{6} +8x^{5}\)

Step-by-step explanation:

The surface area of the square pyramid with a side length of 6 cm and a slant height of 7 cm is 120 square cm.

To find the surface area of a square pyramid, we need to add up the areas of all its faces. A square pyramid has a square base and four triangular faces. We can use the side length of the square base and the slant height of the triangular faces to calculate the surface area.

First, let's find the area of the square base:

Area of square base = (side length)\(^2\)

Area of square base =\(6^2\)

Area of square base = 36 square cm

Next, let's find the area of one of the triangular faces. Since the pyramid is a square pyramid, all the triangular faces are congruent.

To find the area of a triangular face, we need to use the formula:

Area of one triangular face = (1/2) x base x height

Area of one triangular face = (1/2) x 6 x 7

Area of one triangular face = 21 square cm

Finally, we can calculate the surface area of the pyramid by adding the area of the square base and the total area of the triangular faces:

Surface area of square pyramid = area of square base + total area of triangular faces

Surface area of square pyramid = 36 + 84

Surface area of square pyramid = 120 square cm

Therefore, the surface area of the square pyramid with a side length of 6 cm and a slant height of 7 cm is 120 square cm.

The correct option regarding the linear regression equation is:

No, the equation is not a good fit because the sum of the residuals is a large number.

To find the equation, we need to insert the points (x,y) in the calculator.

In possession of the equation, the residuals are given by the difference of the predicted values(with the equation) and the actual values.

The model represents a good fit if the sum of the residuals is close to 0.

For this problem, the sum of the residuals is given by:

90 - 50  - 100 - 100 + 150 - 50 = -60.

The sum is a large number, hence the model is not a good fit.

Connective tissue bands called annular ligaments prevent flexor tendons of the forearm and leg from rising like bowstrings.

Annular ligaments are ring-like structures made of fibrous tissue that surround and hold tendons in place as they pass through tight spaces in the body. In the forearm, the annular ligaments hold the tendons of the flexor muscles in place as they pass under the wrist and into the hand.

In the leg, the annular ligaments hold the tendons of the hamstring muscles in place as they pass behind the knee.

Without annular ligaments, the tendons would be able to move too freely, causing them to bowstring and reducing their effectiveness in controlling movement. The annular ligaments help to keep the tendons in the correct position, allowing them to function properly and enabling smooth and efficient movement of the joints.

Answer: 27 feet per second

Step-by-step explanation:

The difference quotient evaluated in x = 2 gives:

[ f(2 + h) - f(2)]/h = h + 9

So the last option is the correct one.

Here we know the function:

f(x) = x^2 + 5x + 6

And we want to find the difference quotient:

[ f(2 + h) - f(2)]/h

Let's evaluate the function:

f(2 + h) = (2 + h)^2 + 5*(2 + h) + 6

            = 2^2 + h^2 + 4h + 10 + 5h + 6

            = h^2 + 9h + 20

f(2) = 2^2 + 5*2 + 6

f(2) = 4 + 10 +  6 = 20

Then we have:

[ f(2 + h) - f(2)]/h

[h^2 + 9h + 20 - 20]/h

[h^2 + 9h ]/h

Taking the quotient we get:

[h^2 + 9h ]/h = h + 9

So the correct option is the last one.

Hope that helped

Given:

The expression is:

\(10xy+3y+20ax+6a\)

To find:

The complete factor form of the given expression.

Solution:

We have,

\(10xy+3y+20ax+6a\)

By grouping, we get

\(=(10xy+3y)+(20ax+6a)\)

Taking out GCF from each parenthesis.

\(=y(10x+3)+2a(10x+3)\)

Taking out the common factors, we get

\(=(10x+3)(y+2a)\)

Therefore, the correct option is c.

well, since the y-intercept is at -5, or namely when the line hits the y-axis is at -5, that's when x = 0, so the point is really (0 , -5), and we also know another point on the line, that is (-1 ,6), to get the equation of any straight line, we simply need two points off of it, so let's use those two

\(\stackrel{y-intercept}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{-5})}\qquad (\stackrel{x_2}{-1}~,~\stackrel{y_2}{6}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{(-5)}}}{\underset{run} {\underset{x_2}{-1}-\underset{x_1}{0}}} \implies \cfrac{6 +5}{-1} \implies \cfrac{ 11 }{ -1 } \implies - 11\)

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{- 11}(x-\stackrel{x_1}{0}) \implies y +5 = - 11 ( x -0) \\\\\\ y+5=-11x\implies {\Large \begin{array}{llll} y=-11x-5 \end{array}}\)
