Answer: 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

A submarine is cruising 8 meters below the surface. The captain orders a dive of another 17 meters. What is the new cruising dep

swat32

Answer:

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by adding the initial depth of the submarine and the depth further increased upon the order of the captain.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.

Answer:

105, C

Step-by-step explanation:

16x + 1 + 40 = 27x - 3

This is because 180 - (27x - 3) = the missing angle in the triangle shown

16x + 1 + 40 = 27x - 3

1+ 40 = 41

16x + 41 = 27x - 3

+3 +3

16x + 44 = 27x

-16x -16x

44 = 11x

44/11 = x

x = 4

27x - 3 is equal to 27(4) - 3 = 108 - 3 = 105

Ans = 105
