Step-by-step explanation:
Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.
X is N(85, 20)
To convert into std normal variate we use the following formula
a) the probability that he has spent more than $95 at the mall
=
b. the probability that he has spent between $95 and $115 at the mall
=
c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall
=product of two probabilities since independent
=
Answer:
25.6 minutes
Step-by-step explanation: add 11.7 and 2.2 then add 11.7 again
B = 44 degrees
a = 23
b = 12
use law of sines to solve for angle A:
b/sinB = a/sinA
12/sin44 = 23/sinA
12sinA = 23*sin44
sinA = (23*sin44)/12
sinA = 1.3314
since sinx is only defined for values between -1 and 1 it is impossible to form a triangle with given the dimensions. hence no possible solutions
