The weights of cars passing over a bridge have a mean of 3,550 pounds and standard deviation of 870 pounds. Assume that the weights of the cars passing
over the bridge are normally distributed. Use a calculator to find the probability
that the weight of a randomly-selected car passing over the bridge is more than
4,000 pounds.
a) 50%
b) 39.34%
c) 30.42%
d) 69.58%

the answer is c

hope this !

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
