Answer: 240
Step-by-step explanation:
As per given ,
Number of choices for Receiver = 5
Number of choices for CD Player= 4
Number of choices for Speakers = 3
Number of choices for Cassette Deck =4
If a switch board display in the store allows a customer to hook together any selection of components , then by product rule
The number of ways one component of each type be selected = (Number of choices for Receiver) x (Number of choices for CD Player) x (Number of choices for Speakers )x (Number of choices for Cassette Deck)
= 5 x 4 x 3 x 4 = 240
Hence, the answer is 240.
The mean of the given sample data is 210, and the standard deviation is 7.937.
Given size 'n' = 300
The population proportion 'p' = 0.7
Let 'x' be the random variable of the binomial distribution
a) mean of the binomial distribution = n p = 300 × 0.7
μ = 210
b) variance of the binomial distribution
⇒ n p q
⇒ 300 × 0.7 ×0.3
⇒ σ² = 63
The standard deviation of the binomial distribution:
⇒ √n p q = √63 = 7.937
Thus, the mean of the given sample data is 210, and the standard deviation is 7.937.

The question seems to be incomplete the correct question would be:
describe the sampling of p hat. Assume that the size of the population is 25000 n= 300 p=0.7 a) Determine the mean of the sampling distributionb) Dtermine the standard deviation of the sampling distribution
Answer:
200 = c
Step-by-step explanation:
100/45=2.2.
2.2x90= 200.
I can't actually see it good can you do it over please.
C=5800+200(S) is a decent equation
