Answer:
speed of James is: 3.75 miles/hour.
Step-by-step explanation:
We need to find the speed of James in miles per hour(mi/hr)
we know that 1 mile=5280 feet
James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.
i.e. he takes 7200 steps in 1 hour.
also each step of James=2.75 feet
total distance covered by James in 1 hour=2.75×7200 feet=19800 feet
hence speed of James= (distance covered by james in 1 hour)/1 hour
speed of James=3.75 miles/hour.

Answer:
Step-by-step explanation:
Given that X no of students applying for Honors college is binomial with n =1500 and p = 0.13
a) Mean = E(x) = np =
b) Variance= npq =
Std dev =13.025
c) Var = 169.65
d) P(X<160)
=0.00261
e) P(X>200) = 1-F(200)=0.3336
is the formula used.
