Answer:
Option D. 75 miles
Step-by-step explanation:
Looking at the Yellowstone Park map we can see that Mrs. Folwer went from Old Faitful to the Canyon by covering a straight line of .
This tells us that we do not need extra calculations to find the distance covered on the map. We also know that the map scale is given as . So similarly we do not need to do extra ratio conversions.
Thus we know that if and she covered
on the map, we can just multiply covered distance with the equivalency of
in
as follow:
Thus Mrs. Folwer's actual distance from Old Faithful to Canyon in Miles is 75 miles. (<u>which is given in Option D</u>.)
Answer:
Step-by-step explanation:
This is a normal distribution question with
Mean = 153
Standard Deviation= 10
Since we know that score
a)
P(x > 150.0)=?
The z-score at x = 150.0 is,
This implies that
P(x > 150.0) = P(z > -0.3)
= 1 - P(z < -0.3) = 1 - 0.3820885778110474
P(x > 150) = 0.6179
