Answer:
16
Step-by-step explanation:
The mean of a group of values is calculated as
mean = 
Given 5 numbers with a mean of 12, then
= 12 ( multiply both sides by 5 )
sum = 60
let the number removed be x , then
= 11 ( multiply both sides by 4 )
60 - x = 44 ( subtract 60 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
The number removed was 16
Answer: The correct answer is 0.90, 90%, 9:10, and 9/10.
Step-by-step explanation:D
Answer:
0=0
Step-by-step explanation:
Answer:
y(0 | 0,4)
x(0,3 | 0)
As you may observe, it looks like:
x or y (x | y), so that means that in case that we look for y, x will be 0 and if we look for x, y will be 0!
Answer:
12, 7, 2, -3, -8
Step-by-step explanation:
I will only do the first one for an example.
If x was to equal -2 you would put it into the function like this.
f(x)=2-5x
f(-2)=2-5(-2)
f(-2)=2+10
f(-2)=12
