Answer:
22.3 minutes
Step-by-step explanation:
The computation of the travel time is as follows:
Given that
= 17
And, the standard deviation is 4.5
P(X≤C) = 0.88
P( x - ) ÷
≤ (C -
) ÷
= 0.88
(C - ) ÷
= 1.175
c = + 1.175 ×
= 17 + 1.175 × 4.5
= 22.3 minutes
Hence, the travel time is 22.3 minutes
Answer:
Step-by-step explanation:
Based on the information given we can say the two points are (-5, 4) and (-10, 0). An x-intercept is where the line crosses the x-axis giving us a y value of 0.
So, we will use the following formula, where m is equal to the slope.
Now we will plug in the x and y values given above, (-5, 4) and (-10, 0).
Note: In the denominator of the first line, the -5 was changed to a 5 because in the original equation, we are told to subtract. When you have two negatives they cancel each other out.
Hope this helps! <3
