B(w) = 12; Katy will have read 12 books after w weeks
b(2) = 10; the number of books that Katy will have read in 2 weeks is 10
b(3) = f; the number of books that Katy will have read after 3 weeks is f
Remember w is just number of weeks!!
Answer:
The mean of x is close to 14.8.
The standard deviation of x is close to 3.78.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and each trial can only have two outcomes, with probabilities
and
.
For an experiment with n repeated trials and a probability of success
, we have that:
The mean is: 
The standard deviation is: 
In this problem
There are 400 employees, each with a probability of 3.7% of having food allergy. So
. So:

The mean of x is close to 14.8.

The standard deviation of x is close to 3.78.

Answer:
4.) y=x-16
Step-by-step explanation:
Here,
y=4,
x=20
Now,
putting the value of x and y.
or, 4=20-16
or, 4+16=20
∴20=20
