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
A (DE = GF)
In a isosceles trapezoid, one pair of segments are parallel, and another pair are equivalent in length.
The only choice that fits this criteria is A, where DE equals GF.
