Suppose the force actice on a column that helps to support a building is normally distributed random variable X with mean value 1.5 kips and standard deviation 1.25
kips. Which of the following probabilities is the largest?
P(X>17)
P(13 P(X=15)
P(X<14)

step-by-step explanation: 4 cause 2+2=4

i dont get the question

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

i dont know what you want me to answer for this but im guessing 2: 11?
