Answer:
14
Step-by-step explanation:
Substitute x = 2 into f(x)
f(2) = 7 × 2 = 14
no it actually the opinions you have
A nanometer (nm) is 10⁻⁹ m.
Therefore
10⁶ x 1 nm = 10⁶(10⁻⁹ m) = 10⁻³ m
By definition,
10⁻³ m = 1 mm (millimeter)
Answer: 1 millimeter
Answer:
Step-by-step explanation:
Leaving leap years, a year contains 365 days.
For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of

a) Probability that exactly 3 people have same birthday = 
Each day is independent of the other
And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p = 
Expected value of days = np = 
b) Distinct birthdays is binomail with p =1/365 and n = 365
Hence
expected value = np =1
