Answer:
39 - 35 = $4
Step-by-step explanation:
mean: 19+42+35+40+39 = 175
175/5 = 35
add up all the cost then divide by how many numbers there are.
Median:
list the numbers from lowest to largest
19, 35, 39, 40, 42
then find the number in middle
39
last: 39-35=$4
Take the area and divide out what you know, so if you know (w) then divide (w) out from the area
Answer:
<em>Average rate of change is </em><em>-78.</em>
Step-by-step explanation:
A talent competition on television had five elimination rounds. After each elimination, only one-third of the contestants were sent to the next round.
The table that shows the number of contestants in each round of the competition is,
x f(x)
1 243
2 81
3 27
4 9
5 3
Average rate of change is the change in the y-value divided by the change in the x-value for two points on the graph.
i.e 
So, the average rate of change of 
from 
to 
is,
Since f(x) is decreasing, so rate of change is negative.
Answer: The answer is 3/8
Step-by-step explanation: For this problem you only need to multiply the fractions. So when you multiply the two fractions you first multiply both numerators so 1 X 3 = 3 then the denominators 4 X 2 = 8. So the fraction is 3 over 8 3/8.
