Randomly selecting a seventh grader from a school that has 250 sixth graders, 225 seventh graders, and 275 eighth graders

The probability is P = 0.32

Step-by-step explanation:

Here i guess that the question is: "what is the probability of randomly selecting a seventh-grader".

The data that we have is:

We have 250 sixth graders, 225 seventh graders and 275 eight graders, this adds to a total of 700 options.

The probability of randomly selecting a seventh-grader is equal to the number of seventh-graders divided the total number of possible options, in this case, 700.

So we have P = 225/700 = 0.32

This means that the probability of randomly selecting a seventh-grader is equal to 0.32

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
