Answer:
The expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.
Step-by-step explanation:
Given that a box contains 3 defective batteries and 7 good ones, and I reach in and pull out three batteries, to determine what is the expected number of defective batteries, the following calculation must be performed:
3 + 7 = 100
3 = X
10 = 100
3 = X
3 x 100/10 = X
300/10 = X
30 = X
3 x 3/10 = X
0.9 = X
Therefore, the expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

Step-by-step explanation:
We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.
To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:
Therefore, the net profit for the year was .
Answer:
You need to plug the values for d into the equation and find the values then plug them back into Range:
Example for first one:
f(3) = 321.65 x (3) - 567.37 = 397.58
I went ahead and did the other two for you to check your answers.
Domain = { 3 , 17 , 24}
Range = { 397.58, 4900.68 , 7152.23}
