Step-by-step explanation:
Answer:
River weight is 124.05 pounds
Step-by-step explanation:
We are given
Spot weights 75.25 pounds
so,
Spot =75.25 pounds
rover weights 48.8 pounds more than spot
so, we get
Rover = Spot +48.8
now, we can plug value
and we get
Rover = 75.25 +48.8
Rover = 124.05 pounds
So,
River weight is 124.05 pounds
Answer:
The expected number of sales of this store from this sample of 30 is 6.
Step-by-step explanation:
For each prospect, there are only two possible outcomes. Either there is a trade, or there is not. Prospects are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

A retail variety store that advertises extensively by mail circulars expects a sale with 20% probability.
This means that 
Suppose 30 prospects are randomly selected from a city-wide mailing.
This means that 
What is the expected number (mean) of sales of this store from this sample of 30?

The expected number of sales of this store from this sample of 30 is 6.
Answer:
Flooring: 155 | Cost: 968.75
Step-by-step explanation:
10 x 15 1/2 = 155
then multiply the 155 with the 6.25
you will get 968.75
so the cost is $968.75
The answer is 85 let me explain:
All you do for the mean is add all the values(numbers) together, and then divide by the amount o f numbers.
so your number set is
87,84,86,79,84,90
so all we do is add them all together
87 + 84 + 86 + 79 + 84 + 90
which equals 510
then we divide by the amount of values (numbers) there are.
since there are 6 numbers in this data set we have to divide 510 by 6
which gives us a quotient of 85
so 85 is your answer.
