Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
Yeah B it’s B I’m pretty sure

Answer:
13/4
Step-by-step explanation:
Convert these numbers to a mixed fraction.
-5 3/4 => -23/4
-2 1/2 => -5/2
Make them have a common denominator
-5/2 => -10/4
-23/4 can stay the same.
To find the distance between the two numbers, subtract the lesser value from the greater value.
-23/4 is <u>less</u> than -10/4.
(-10 - (-23)) /4
= 13/4
Therefore the distance between -2 1/2 and -5 3/4 on a number line is 13/4.
(f o g)(x) = 1/(x - 13) +7
domain of the function is all real x except x = 13
