The graph below shows the height through which an elevator travels, y, in x seconds: a graph is shown with x axis title as time in seconds. the title on the y-axis is height of elevator above ground in feet. the values on the x-axis are from 0 to 5 in increments of 1 for each grid line. the values on the y-axis are from 0 to 50 in increments of 10 for each grid line. a line is shown connecting points at ordered pairs 1,10 and 2, 20 and 3, 30 and 4, 40. the title of the graph is rate of ascent. what is the rate of change for the relationship represented in the graph? fraction 1 over 40 fraction 1 over 10 10 40

the answer is 10 or letter C

Step-by-step explanation:

C. 10

Step-by-step explanation:

We are given a graph representing the height of the elevator with respect to time.

Since, we know that,

X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.

As, the coordinate points on the graph are given by,

(1,10), (2,20), (3,30) and (4,40).

So, the rate of change can be found out by solving, .

Hence, the rate of change of the relationship is 10.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
