1. The distribution of the weights of Peruvian rams is approximately normal with mean 75 kg and standard deviation 7 kg. (Really-Someone weighed a lot of them.)
a. Sketch a graph of this distribution, with a scale on the horizontal axis.
of data
b. What percentage of Peruvian rams weigh more than 89 kg?
C. Would it be unusual for a Peruvian ram to weigh 65 kg?
Explain your

y > 1/3x

y < = -x + 4

hope this : )

there are no answer choices

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
