Answer:

B. 60cm^3

Step-by-step explanation:

The volume of a right triangular prism is

V = BH where B is the area of the triangle and H is height

B = 1/2 bh where b =5 and h =8

B = 1/2 *40 = 20

V = (20) * 3

V = 60 cm^3

We need to be careful to do the area of the triangle first

Determine the number of outcomes in the event. Decide whether the event is a simple event or not.

Anna35 [415]

Answer:

<u>No</u>, The event B is not a simple event because event B has <u>more than one</u> outcome.

Step-by-step explanation:

Consider the provided information.

A computer is used to select randomly a number between 1 and 9 comma inclusive.

Event B is selecting a number greater than 4.

Let B be an event that the selected number greater than 4.

We have given that the total number used by the computer is:

1, 2, 3, 4, 5, 6, 7, 8, 9

Now the sample space for selecting a number greater than 4 is:

S = {5, 6, 7, 8, 9}

Therefore, the event B has 5 outcomes.

The event B is not a simple event because event B has more than one outcome.

Write a scenario that could work for the following line of best fit: y = x + 1. Explain the slope and intercept in this context.

ZanzabumX [31]

The registration for new members of a gym is $ 1.
The gym payment per day is $ 1.
The equation that models this problem is:
y = x + 1
Where,
x: is the number of training days
y: it is the total payment
The intersection with the y axis (1) represents the cost of the inscription.
The slope of the line (1) represents the daily payment.

Alex is building a rectangular fence around his yard. The total perimeter of the fence is 68 feet and the area of the yard is 24

pychu [463]

Perimeter (P) = 2L + 2w

68 = 2L + 2w

68 - 2L = 2w

2(34 - L) = 2(w)

34 - L = w

********************

Area (A) = L * w

240 = L (34 - L)

240 = 34L - L²

L² - 34L + 240 = 0

(L - 10)(L - 24) = 0

L = 10 or L = 24

w = 34 - L = 34 - 10 = 24 or w = 34 - 24 = 10

Answer: width = 10, length = 24 assuming length is bigger than the width
