Answer:

There are 60 activity booklets in the media lab.

Step-by-step explanation:

- 30/2 = 15

Why divide those numbers?

For every 2 computers in a lab with 30 computers means you have to divide

- 15x4 = 60

Why multiply those numbers?

4 activity booklets for every 2 computers in a lab of 30 computers, so multiply

I hope this helps.

On your cell phone bill, you are charged $0.25 for each text you send. What is the dependent variable?

zhannawk [14.2K]

Answer:

The amount of the bill is dependent on the number of texts sent. Let y be the bill amount and x the number of texts. Then x is independent and y is dependent. This is because x can be any non-negative number, but y depends upon it. You cannot find the bill without knowing the number of text messages, right?

This net will be folded to form a prism.

allsm [11]

The opposite faces are D and F, A and C, and B and E. Then the correct options are A, B, and E.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

This net will be folded to form a prism.

A net of a rectangular prism.

From top to bottom, the rectangles are labeled B, D, E, and F.

The left side is labeled A and the right side is labeled C.

Then the pairs of faces will be opposite one another when the prism is created will be

BD, DE, EF, FB, AD, DC, CF, FA, AB, BC, BE, and EA all are the adjacent side faces.

AC, BE, and DF are the opposite faces.

Then the correct options are A, B, and E.

There are 4 jacks and 13 clubs in a standard, 52-card deck of playing cards. What is the probability that a card picked at rando

ale4655 [162]

Answer:

16/52, or 4/13.

Step-by-step explanation:

First, since we know that the question is asking for the probability of a club <u>or</u> a jack, we know that we have to add the two probabilities. The first probability is that of picking a club, which is 13/52. The probability of picking a jack (be sure not to overlap; don't double count the jack of clubs) is 3/52. Adding these two gives us 13/52+3/52=16/52, which simplifies to 4/13.

the probability that a twelve year old has a brother or sister is 25%. suppose you survey 300 twelve year olds. about how many d

Genrish500 [490]

Answer:

n(B U S) = 75

Step-by-step explanation:

Explanation:-

<u>Probability</u>:-

P(E) = $\frac{number of elements events in E}{total number of elementary events in the random experiment}$

$P(E) = \frac{m}{n}$

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data P(BUS) = 0.25

given total survey n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) = $\frac{n(BUS)}{n(survey)}$

substitute given values, we will get solution

$0.25 = \frac{n(BUS)}{300}$

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75
