Answer:
10 x 4 = 40 square feet
40 Square Feet x $2 per square foot = $80.00
Step-by-step explanation:
Because the distribution (normal) is symmetric, you know that
, so
Now,
If
is the CDF of the normal distribution, so that
, then the z-score satisfies
so that
.
Answer= 40%
40% of call are for air conditioners
1/5 of calls are for heaters
First, lets convert 1/5 into a decimal, and then a percent value.
1/5=0.20=20%
20% of calls are for heaters
100% represents the amount of service calls Mike receives.
100%-40%-20%=
100%-60%=40%
40% of the service calls Mike receives are other calls.
Answer:
51
Step-by-step explanation:
I think the answer is 51 because you have to find the number between the first three to the middle
The point R has coordinates (-5,-5) and the image point R' has coordinates (2,-7).
If
- -5+a=2, then a=2-(-5)=2+5=7;
- -5+b=-7, then b=-7-(-5)=-7+5=-2.
Thus, the translation rule is
(x,y)→(x+7,y-2)
or 
If point U has coordinates (-5,1), then its image U' has coordinates (-5+7,1-2) that is (2,-1).
