A survey of 30 students each from three different high schools was conducted to find the number of hours they spent every month on volunteer work. Based on the median values of the data sets, represented here as dot plots, which conclusions are true? The students in school 2 generally spend more time doing volunteer work than the students in school 1.
The students in school 1 generally spend more time doing volunteer work than the students in school 2.
The students in school 1 generally spend more time doing volunteer work than the students in school 3.
The students in school 1 generally spend less time doing volunteer work than the students in school 3.
The students in school 3 generally spend more time doing volunteer work than the students in school 2.

part a

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

d is the answer
