Of the 17 students in a programming class, 6 own 1 computer, 3 own 2 computers, 3 own 3 computers, 2 own 4 computers, and 3 own
AlexFokin [52]

The median number of computers owned by the 17 students is 2.

<h3>What is median in statistics?</h3>

A dataset's median represents the midpoint; half of the data points are smaller and half are greater than the median.

Identifying the median: The data points should be arranged from smallest to largest. The median is the middle data point in the list if the number of data points is odd.

The total number of students are 17.

The data can be arranged in the following table

number of students        number of computers

             6                                         1

             3                                         2

             3                                         3

             2                                         4

             3                                         5

Arrange the given frequencies in the increasing order-

1 1 1 1 1 1 2 2 2 3 3 3 4 4 5 5 5

The middle term of the arrange frequencies is 17/2 = 8.5

Median = (8 term + 9 term)/2

            = (2 + 2)/2

            = 2

Therefore, the median number of computers owned by the 17 students is 2.

62.4% of what is 17.16?
Maksim231197 [3]
To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 17.16 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 17.16 is 100%, so we can write it down as 17.16 = 100%.

4. We know, that x is 62.4% of the output value, so we can write it down as x=62.4%

5. Now we have two simple questions:

1) 17.16 = 100%

2) x=62.4%

Where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

17.16÷x=100%÷62.4%

6. Now we just have to solve the simple equation, and we will get the  solution we are looking for.

7. Solution for what is 62.4% of 17.16

17.16÷x=100/62.4%

(17.16÷x)×x=(100÷62.4%)×x

17.16=1.60256410256×x

(1.60256410256) to get x

17.16÷1.60256410256=x

10.70784=x

x=10.70784

Now we have:
62.4% of 17.16=10.70784

So 10.70784 is your answer

Hope this  helps :)
