Answer:

Only the mean increased.

Step-by-step explanation:

The mean is the total divided by the number of scores, and since adding 21 will increase the total score significantly, the mean increases.

The median is still 7.

<h2>Writing the Inverse of a Function</h2><h3>Answer:</h3>

$f^{-1}(x) = \sqrt[3]{\frac{x +5}{3}}\\$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my Answer from this Questions to know more about Inverse Functions: <u>brainly.com/question/24619467</u></em>

Let $y = f(x)$ so that the inverse of $y$ is equal to $f^{-1}(x)$ .

Solving for $f^{-1}(x)$ :

$f(x) = 3x^3 -5 \\ y = 3x^3 -5 \\ x = 3y^3 -5 \\ 3y^3 -5 = x \\ 3y^3 = x +5 \\ y^3 = \frac{x +5}{3} \\ y = \sqrt[3]{\frac{x +5}{3}}$

Since the inverse of $y$ is equal to $f^{-1}(x)$ , $f^{-1}(x) = \sqrt[3]{\frac{x +5}{3}}\\$ .

3 times negative 11 is negative 33 and 3 times 2 is 6, so you have negative 33 divided by 6 and that is negative 5.5

Answer:

The vertex that maximize the problem is (2,000,4,000)

Step-by-step explanation:

we have

$z=10x+6y$

The vertex of the shaded region are

A(0,0), B(4,000,0),C(2,000,4,000), D(0,6,000)

Substitute the value of x and the value of y of each vertex in the z equation to find the solution

case A) A(0,0)

$z=10(0)+6(0)=0$

case B) B(4,000,0)

$z=10(4,000)+6(0)=40,000$

case C) C(2,000,4,000)

$z=10(2,000)+6(4,000)=44,000$

case D) D(0,6,000)

$z=10(0)+6(6,000)=36,000$

therefore

The vertex that maximize the problem is (2,000,4,000)
