If there are 22 successes in a sample with a size of 40, what is the sample
proportion?

A. 0.55
B. 0.65
C. 0.44
D. 0.22

Answers

Answer 1

Answer:

A

Step-by-step explanation:

22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.

22/2 = 11

40/2 = 20

Now you have 11/20. Put this in decimal form and you have 0.55

Answer 2

Option A answer is 0.55

What is the proportion of a sample?

The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.

The solution to the given problem

The size of the sample is 40.

There are 22 successes in the sample.

To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55

Hence option A is correct, the proportion is 0.55

Answer:

4 horses

Step-by-step explanation:

There are 2 elephants and 4 horses on one side. On the other, there are 12 horses. You can cancel 4 horses so now it's 2 elephants and 8 horses. To get the first side (2 elephants) to turn into one elephant, you need to divide by 2. So now, it is 1 elephant = 4 horses.

Answer:

4

Step-by-step explanation:

4 because you can write the problem as  2e+4h=12h then you subtract 4h from both sides and get 2e=8h then you divide by 2 to get e=4 so one elephant is as strong as 4 horses

h=horses

e=elephant
