Answer:
b). There is little to no evidence to conclude the mean driving time for the alternative route is different from the mean driving time of the detour.
Step-by-step explanation:
The most adequate statement to examine the proposition is that 'there is lack of adequate evidence to substantiate the claim that the mean time taken for driving through the detour and the alternative route is distinct.' This will help in testing that <u>there is a lack of evidence to establish the validity or truth of the proposition that if the detour is actually shorter than the alternative route or not</u>. No data has been provided to clarify that the mean driving time in both routes traveled by Sarah was varied. Hence, <u>option b</u> is the correct answer.
Answer:
Step-by-step explanation:
Given:
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Stress, S = 30000 psi
Elongation, x = 0.50 in
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
= 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi × d^2)/4
0.3 = (pi × d^2)/4
= sqrt(1.2/pi)
diameter, d = 0.62 inches
