Answer:
Step-by-step explanation:
Given
Sample Size = 2500
Percentage = 30%
Required
Calculate Mean of Y
Mean or Expected Value is calculated as thus;
Where E(Y) represents the mean
n represents the sample size (or population)
p represents the success probability
%
So,
Hence, the mean value of Y is 750
You take the reciprocal of the original slope and negate it
Answer:
$220.875
Step-by-step explanation:
For 1 hour you get $7.75
To find how much money you make in 28.5 hours... you multiply the number of hours with the number of dollars.

<span>4 x 4 x 4 x 4 x 4 x 4 = 4^6
answer is 4^6</span>
Subtract -9 from both sides.
x2+6x−(−9)=−9−(−9)
x2+6x+9=0
Factor left side of equation.
(x+3)(x+3)=0
Set factors equal to 0.
x+3=0 or x+3=0
x=−3
Answer:
x=−3
