it shows that the least amount of time spent on internet surfing is 37.5 mins and the most amount of time spent on internet surfing is 60 mins but it does not show how many students were asked about how much time they spent on the internet

part b

the interquartile range is the range on the box on top of a range. the interquartile range is 37.5-60 mins

part c

if there is an outlier present such as a student who spent 95 mins surfing the internet that could affect the average, mean, mean absolute deviation, and the median by either raising or lowering it.

What is the value of x?
4 ⋅ x = 28

Answers

X = 7.

This is because in order to find the value of x you need to do inverse operations. So since this is a multiplication problem you need to do division to find the value of x. 28 divided by 4 = 7. And that’s pretty much it!

A county has the following rule for voting: "Citizens under the age of 18 are not allowed to vote."

Part A: Write an inequality to show the age of citizens who are allowed to vote.

Part B: Describe in words how you can show the solution to this inequality on a number line.

Answers

Answer: Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.

let x = the citizens under the age of 18

x < 18 is your inequality (Part A)

For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).

-2n + 1.8 = 3.2

Options: -0.7, -3.4, 0.7, -2.5

Answers

Answer:

-0.7

Step-by-step explanation:

-2 x -0.7 =1.4

1.4 +1.8 = 3.2

-2n + 1.8 = 3.2
-1.8 = -1.8
-2n = 1.4
Now divide both sides by -2 and you get n = -0.7

All you do is solve for n to get your answer

What is the height of a rectangular prism that has a volume 192 cubic feet and a base with an area of 48 square feet?

Answers

Answer:

A rectangular prism has 3 measurements: length (l), width (w), and height (h)

The volume of a rectangular prism has the formula: V=lwh

The area of the base of the rectangular prism is its length times its width; or

Area of base = lw

So, the volume of the rectangular prism can be written as:

Volume = area of the base * height

Substitute in your numbers:

192=48*h

h=192/48

h=4

So the height is 4 feet

Step-by-step explanation: Hope this helps. :))

Amanda covers the outside of a box, shown in the diagram below, with decorative paper for a school project. The top of the box is open.

If the paper costs $0.03 per square inch what is Amandas total?

Answers

Answer:

C. $4.38

Step-by-step explanation:

To find out how much paper she covers the box with, you need to find the area of each of the rectangles covered by the box.

First, find the area of the side closest to you.

3 x 8 = 24 in^2

Since the side opposite to it is equivalent, they are both 24 in^2, so multiply 24 by 2:

24 x 2 = 48 in^2

Now, find the sides on the left and right (equal in size).

7 x 3 = 21

21 x 2 = 42 in^2

Finally, find the bottom. There is no top, so there's no need to multiply this one by 2.

8 x 7 = 56 in^2

Add up the sides:

56 + 42 + 48 = 146 [tex]in^2[/tex]

Multiply 146 by 0.03:

146 x 0.03 = 4.38

$4.38
