Answer: 0.0227502
Step-by-step explanation:
Let x denote the random variable that represents the mileage of SUV.
As per given we have,
sample size : n= 36
We assume that the mileage of SUV is normally distributed.
Z-score value corresponds to x= 21.0,
Using standard z-value table ,
The probability that the sample average will be over 21.0 mpg:-
P(X>35)=P(z>2)=1-P(z<2)=1-0.9772498=0.0227502
Hence, the required probability = 0.0227502

Answer:
Step-by-step explanation:
The number to be added is the square of half of the linear term coefficient. Such coefficient in our case is "10" (the number accompanying the variable x). Then, half of it is 10/2 = 5, and that number squared gives 25.
Therefore, the number to add on bothsides of the equality is 25, which leads to the following:
This matches answer B) of your choices.
The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
