Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
Answer:
Explanation:
The time when they meet is t in hours
The general formula for both cars is d = r*t
t is unknown
r1 = 55 mph
r2 = 60 mph
60 mph * t + 55 mph*t = 100 miles
t * (60 mph + 55 mph) = 100 miles
t * 115 = 100 miles
t = 100 miles / 115 mph
t = 0.8696 hours
1 hour has 60 minutes
0.8696 hour = x
x = 0.8696 hours * 60
x = 52 minutes and 10 seconds
They will meet at 2:52:10

a and b represent the slopes in the equations. Use the y-mx+b formula to realize this. M is the slope, a or b in this question. The lines both have positive slopes so B or C cannot be the answer. I cant see the image properly, but if the y int is at 0 then A is the answer, but if it is above 0 then D will be your answer.
