Answer:
<u>PQ = 54</u>
Step-by-step explanation:
The rest of the question is the attached figure.
As shown:
triangle RPQ is similar to triangle RTS.
So, the corresponding sides are in proportion.
From the figure:
TS = 36 , RP = 42 AND RT = 28
∴
∴ PQ = 36 * 42/28 = 54
<u>So, the distance between P and Q = 54</u>
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
