Eva earned the following test scores in science: 82, 100, 96, 90, 91 Ms. Wade entered the next score as 0 because Eva was absent

on test day and hadn’t had a chance to make up the test. Which statements are true based on the data? Check all that apply. After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data. After adding the 0 test score, the mean would be affected. After adding the 0 test score, the median would be the most appropriate measure of center to describe the data. Before the missed test, Eva’s median score was 96. Before the missed test, Eva’s median score was 91. Before the missed test, Eva’s mean score was 91.8.

we know that

1) Before the missed test

a) mean=[82+100+96+90+91]/5=459/5------> 91.8

b) median

82,90,91,96,100-------> the median is 91


2) After adding the 0 test score

a) mean=[82+100+96+90+91+0]/5=459/6------> 76.5

b) median

0,82,90,91,96,100-------> the median is [90+91]/2-----> 90.5


therefore

a) After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data-------> is true


b) After adding the 0 test score, the mean would be affected-----> is true


c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data-----> is false


d) Before the missed test, Eva’s median score was 96-----> is false


e) Before the missed test, Eva’s median score was 91------ is true


f) Before the missed test, Eva’s mean score was 91.8-----> is true

Which equation is the inverse of y = 9x2 – 4? y = StartFraction plus-or-minus StartRoot x + 4 EndRoot Over 9 EndFraction y = plu
andre [41]

Option C: y=\pm\frac{\sqrt{x+4}}{3} is the inverse of the function

Explanation:

The given function is y=9 x^{2}-4

We need to determine the inverse of the function.

To determine the inverse of the function, we need to interchange the values of x and y and solve for y.

Let us interchange the variables x and y in the function y=9 x^{2}-4, we have,

x=9 y^{2}-4

Adding both sides of the equation by 4, we have,

x+4=9 y^{2}

Dividing both sides of the equation by 9, we have,

\frac{x+4}{9} =y^2

Switch sides, we have,

y^2=\frac{x+4}{9}

Taking square root on both sides of the equation, we have,

y=\pm\frac{\sqrt{x+4}}{3}

Thus, the inverse of the function is y=\pm\frac{\sqrt{x+4}}{3}

Therefore, Option C is the correct answer.

Photon Lighting Company determines that the supply and demand functions for its most popular lamp are as follows: S(p) = 400 - 4
BlackZzzverrR [31]
S(p) = 400 - 4p + 0.00002p^4
D(p) = 2800 - 0.0012p^3

S(p) = D(p)
400 - 4p + 0.00002p^4 = 2800 - 0.0012p^3
0.00002p^4 + 0.0012p^3 - 4p - 2400 = 0
p = $96.24

A rectangle has a height of w^2+3w+9w 2 +3w+9w, squared, plus, 3, w, plus, 9 and a width of w^2+2w 2 +2w, squared, plus, 2. Expr
Keith_Richards [23]

Answer:

w⁴+5w³+17w²+24w +18

Step-by-step explanation:

Area of a rectangle = length * width

Given

Length  = w²+3w+9

width = w²+2w+2

Area of the rectangle = (w²+3w+9)(w²+2w+2)

Area of the rectangle = w²(w²) + 2w(w²) + 2w² + 3w(w²) + 3w(2w) + 2(3w)+9w²+9(2w)+9(2)

Area of the rectangle = w^4+2w^3+2w²+3w^3+6w^2+6w+9w²+18w+18

Collect the like terms;

Area of the rectangle = w^4+2w^3+3w^3+2w²+6w²+9w²+6w+18w+18

Area of the rectangle = w⁴+5w³+17w²+24w +18

Hence the area of the entire triangle is w⁴+5w³+17w²+24w +18
