Answer:
Rate of change = 2.08%
Step-by-step explanation:
In 1995, 12,000 students
In 2000, 12,250 students
Rate of change = ((12,250 - 12,000)/12,000) × 100 .
= 250/12,000 × 100 = 2.08%
In decimal form its 0.64 and in fraction form its 16/25 :) (simplified from 64/100)
Answer:
11.1% change
Step-by-step explanation:
first find their differences
80-72 =8
secondly
set up a fraction to find the percentage change
because percentage deals with fractions
8/72 *100 ( because percentage is over 100)
lastly
you simply
0.111111*100
=11.11%. ans
Answer:
a) E(y) = 0.8
b) The average subcharge is $165
Step-by-step explanation:
We are given the following distribution in the question:
y: 0 1 2 3
P(y): 0.50 0.25 0.20 0.05
a) E(y)
b) Expected value of subcharge
Subcharge =
Expected value of subcharge =
Thus, the average subcharge is $165
B. (-2,1)
By checking the x coordinates, I saw there was two -2, but the output was different, so one of them had to be taken out to make it a function.
Function: Every input must have one out must.
