Answers

Answer 1

Answer:

The mean weekly allowance is $3.5

Step-by-step explanation:

to find the average, we add up everything, and divide it by how many students there are.

0, 0, 0, 0, 0, 0, 0, 3, 3, 3, 3, 3, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 8, 8 <- this is what you add up

you get 84.  Then you divide this amongst all of the students.

7+5+7+3+2=24

84/24 = 3.5

Please give brainliest!

Hope this helps :)

Answer 2
the answer is $3.5
you multiply the amount of money with the amount of students then add it all together after you get your total ($84) you add the number of students including those who had no money (24) you then divide 84/24 your answer is $3.5

What is the area and circumference of the circle (3.14 for pi)

Answers

We will use the proper formula and solve.

    -> A diameter of 48 / 2 = 24 feet as our radius

   Area:

A = πr²

A = (3.14)(24)²

A = 1,808.64 ft²

      The circle has an area of about 1,808.64 ft²

   Circumference:

C = 2πr

C = 2(3.14)(24)

C = 150.72 ft

      The circle has a circumference of about 150.72 ft

Enter the answer in the box.

Answers

The interquartile range of the data set is 7.

Step-by-step explanation:

The given set of data is {18 , 17 , 10 , 25 , 20 , 20 , 30 , 18 , 18 , 30 , 25}

Arrange the data in ascending order:

10 , 17 , 18 , 18 , 18 , 20 , 20 , 25 , 25 , 30 , 30

Divide the data in two equal parts:

(10 , 17 , 18 , 18 , 18), 20 ,(20 , 25 , 25 , 30 , 30)

Divide each parenthesis in 2 equal parts:

(10 , 17), 18 ,(18 , 18), 20 ,(20 , 25), 25 ,(30 , 30)

Now we can say that,

Q₁ = 18 , Median = 20 , Q3 = 25

Interquartile rage of a data is :

I.Q.R. = Q3 - Q1

I.Q.R. = 25-18 = 7

Therefore the interquartile range of the data set is 7.
