Answer:

Statistics;
Parameter;
Statistics;
Parameter.

Step-by-step explanation:

According to southeastern.edu,

parameters summarize data from an entire population, whereas
statistics summarize data from a sample of the population.

The first statement is true for the sample "those surveyed" the population but not necessarily the entire population. Statistic.

The second statement implies that the soccer team is the population. All members of the population are surveyed. Parameter.

The third statement states that a sample of 100 of all swimming teams are surveyed. Statistic.

The fourth statement implies that the population is all members of the golf team, and that all members of the population are surveyed. Parameter.

Find the perimeter

MAXImum [283]

Answer:

5 + 8 + 11 + 10 = 34

Step-by-step explanation:

The lengths of the horizontal and vertical sides are easily determined. The slant side is seen to be the hypotenuse of a 3-4-5 triangle (times 2), so is 10 units long. The perimeter is the sum of the side lengths:

5 + 8 + 11 + 10 = 34

_____

You can always estimate the length of the hypotenuse of a right triangle as being between 1 and 1.5 times the length of the longest side. Here, the longest side of the right triangle whose hypotenuse is of interest is 8 units, so the hypotenuse will be between 8 and 12 units long. That means the perimeter of the blue trapezoid will be between 32 and 36, a guess of sufficient accuracy to allow you to choose the correct answer.

In a figure like this, you can also measure the hypotenuse on the grid. Using a compass, ruler, or a piece of paper with a couple of marks, you can rotate the slant length so that it corresponds to a vertical or horizontal grid line. Then the length of it is easily estimated to good accuracy. (See the second attachment.) As we said in the previous paragraph, even poor accuracy is sufficient to choose the correct answer.

Answer:

rectangular prism: 288 ft³
triangular prism: 72 ft³
total: 360 ft³

Step-by-step explanation:

The volume of a rectangular prism is given by the formula ...

V = LWH . . . . . the product of length, width, height

This rectangular prism has a volume of ...

V = (12 ft)(6 ft)(4 ft) = 288 ft³ . . . . rectangular prism volume

The volume of a triangular prism is found from the formula ...

V = Bh

where B is the area of the triangular base, and h is the height of the prism (distance between the triangular bases). The triangular base area is found from ...

A = 1/2bh . . . . .where b is the base of the triangle, and h is its height.

Here, we have ...

B = 1/2(6 ft)(4 ft) = 12 ft²

V = Bh = (12 ft²)(6 ft) = 72 ft³ . . . . triangular prism volume

The total volume of the given geometry is the sum of the volumes of the parts:

aquarium volume = 288 ft³ +72 ft³ = 360 ft³
