Carmen surveys a random sample of 35 students from her school. Of these students, 2 are chess club members. If there are 550 students at her school, how many of them are likely to be chess club members?​

Answers

Answer:

31

Step-by-step explanation:

2 out of 35 are chess club members.

The fraction of chess club members in the survey is 2/35.

Now we find 2/35 of 550.

2/35 * 550 = 1100/35 = 31.43

Answer: 31

If there are 550 students at her school, then there are 31 chess club members in the entire school.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

If Carmen surveyed a random sample of 35 students and found that 2 are chess club members.

We can set up a proportion to solve for this:

2/35 = x/550

where x is the number of chess club members in the entire school.

To solve for x, we can cross-multiply and simplify:

2 × 550 = 35 × x

1100 = 35x

Divide both sides by 35.

x = 1100/35

x ≈ 31.43

Therefore, we can estimate that there are approximately 31 chess club members in the entire school.

A rectangular prism has a length of 112feet, a width of 212feet, and aheight of 8 inches. What is the volume of the prism in cubic inches?
pls hurry :)

Answers

Answer:

27,353,088 cubic inches

Step-by-step explanation:

How to find the volume of a rectangular prism

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

Solve

In this case, The volume of a rectangular prism with a length of 112feet,

width of 212 feet, and height of 8 inches:

But in this case, we need to convert both the length and width to inches.

If 1ft = 12in

Then, 112ft = 1344in  (Multiply 112 by 12)

Also, 212ft = 2544 (Multiply 212 by 12)

So, the volume = 1344 x 2544 x 8

Calculated out this gives a volume of 27,353,088 cubic inches.

Answer:

11.25 or 11 1/4

Step-by-step explanation:

seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole

so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-

now we need the dimensions of each one-

rectangle one

l=5 w=2

rectangle two

l=5 w=1/4

now let us set up the equation and solve-

a=lw

rectangle one

a=5*2=10

rectangle two

a=5*1/4=1.25

and the last step is to add together the areas of both rectangles

10+1.25=11.25

and since you need your answer as a mixed number the answer is 11 1/4

(to do this you just put 11.25 over 100 and then simplify)

good luck :)

45 people in a certain company can work together to finish a project in 15 days. For a project of the same workload, the
company decided to use 15 people. Assume all people have the same level of productivity.
In how many days can this project be completed?
SELECT ONLY ONE
5 days
10 days
22.5 days
45 days

Answers

Given:

45 people will accomplish the given task in 15 days.

To find:

Days taken by 15 people to complete the same task.

Solution:

Since, 45 people of a company can finish a work in 15 days

Therefore, 1 person can accomplish the task in days = [tex]15\times45[/tex]

                                                                                        = [tex]675[/tex] days

15 people will accomplish the same task in number of days = [tex]\frac{675}{15}[/tex]

                                                                                                    = [tex]45[/tex]

Therefore, number of days taken by 15 people to accomplish the same task will be 45 days.
