Step-by-step explanation:
Answer:
mean=14, variance=9.1
Step-by-step explanation:
for binomial distribution
n=number of outcomes
p=probability of succcess
q=probability of faliure
p+q=1
any probability given is always 'p'
mean=np
n=40
p=0.35
mean=40*0.35
mean=14
variance=npq
p+q=1
q=1-p
q=1-0.35
q=0.65
variance=40*0.35*0.65
variance=9.1
The required expressions are both equations 1 and 2 as shown:

Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.
According to the question, if two complementary angles have measures of s and t then:

Twice of 's' is expressed as 
If t is less than twice s, this can be expressed as
