Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston measures the wall using a meter stick as shown below. How many cans of paint must kierston buy to paint the wall of the youth center?

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]1\ can = 2.2m^2[/tex]

Required

Determine the number of cans for the wall

The dimension of the wall is not given. So, I will use the following assumed values:

[tex]Length=20m[/tex]

[tex]Width = 44m[/tex]

First, calculate the area of the wall

[tex]Area = Length * Width[/tex]

[tex]Area = 20m * 44m[/tex]

[tex]Area = 880m^2[/tex]

If [tex]1\ can = 2.2m^2[/tex]

Then [tex]x = 880m^2[/tex]

Cross Multiply:

[tex]x * 2.2m^2 = 1 * 880m^2[/tex]

[tex]x * 2.2m^2 = 880m^2[/tex]

[tex]x * 2.2 = 880[/tex]

Make x the subject

[tex]x = \frac{880}{2.2}[/tex]

[tex]x = 400[/tex]

400 cans using the assume dimensions.

So, all you need to to is, get the original values and follow the same steps

A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison.

Which design is the most appropriate for this experiment?

A Randomly number each person with 1, 2, or 3. Assign the people labeled 1 to the device 1 group, the people labeled 2 to the device 2 group, and the people labeled 3 to the device 3 group.
B Number each participant from 1 to 120. Reading numbers from left to right from a random number table, identify 80 unique numbers from 1 to 120. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
C Number each participant from 000 to 119. Reading numbers from left to right on a random number table and looking at three digits at a time, identify 80 unique three-digit numbers from 000 to 119. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
D Select a participant, and identify the first digit reading numbers from left to right on a random number table. If the first digit is a 1, 2, or 3, assign the participant to the device 1 group. If the first digit is a 4, 5, or 6, assign the participant to the device 2 group. If the first digit is a 7, 8, or 9, assign the participant to the device 3 group. If the first digit is a 0, skip that digit and move to the next one to assign the participant to a group. Repeat this process for each participant.
