The anwser is C because your suppose to line it up like this, 4x+4=6x-14, then you solve for x. Once you have x then you plug it in and solve. For your x you will get 9.
Answer:
option A: 0.2357
Step-by-step explanation:
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39)
P(X < 1.76) = 0.0126 (as per the excel output)
P(X < 2.39) = 0.7769
Hence P( X> 2.39) = 1- 0.7769 = 0.223
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39) = 0.0126 + 0.223 = 0.2357
P( less than 1.76 or greater than 2.39) = 0.2357
The formula which relates Distance, av.Speed and Time is

The maximal Distance would be covered if the average speed was 6.3 miles per hour.
In that case D=6.3 (mi/h) * 2 h = 12.6 mi
thus, if x represents the number of miles, x≤12.6 mi
Answer: x≤12.6 mi
Second answe is the correct answer
