Answer:
Since both and , you can use a normal distribution to approximate the binomial distribution.
The mean is of 11.1 and the standard deviation is of 2.64.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Using the normal distribution to approximate the binomial distribution.
This is possible if:
A survey of U.S. adults found that 37% have been to court. You randomly select 30 U.S.
This means that
Test if it is possible:
Since both and , you can use a normal distribution to approximate the binomial distribution.
Mean and standard deviation:
The mean is of 11.1 and the standard deviation is of 2.64.
1. first we find how many defective capacitors are there out of 133, 450:
in 34 capacitors --------- 1 defective
in 133,450 capacitors --------- x defective
so
is the expected number of defective capacitors.
2.
So there are in total 133,450-3925=129,525 working capacitors.
3.
To assemble 1,987 smartphones the corporation needs 1,987*66= 131,142 working capacitors.
4.
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.

4 8/10 48/10, there ya go
Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3
