mel-nik [20]
Im not sure if i am understanding the question correctly... 

If you are asking if Jama's mom is correct, then no. she is wrong. this is because 

if you take the proportion,  (is/of)=(%/100) you get (x/30)=(70/100). You then solve for x which in this case would be 21 students are wearing tennis shoes.

4, 6, 2, 8, 4, 4, 2, 10<br> Mean:<br> Median:<br> Mode:
Troyanec [42]

Answer:

Mean: 5

Median: 4

Mode: 4

Step-by-step explanation:

Mean:

1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.

  • \frac{4+6+2+8+4+4+2+10}{8}
  • \frac{40}{8}
  • 5

Therefore, the mean is 5.

Median:

1. To find the median given a data set, we first have to arrange the data points in order.

  • 2, 2, 4, 4, 4, 6, 8, 10

2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.

Therefore, the median is 4.

Mode:

1. To find the mode given a data set, you just have to find which data point is the most frequent.

  • 1 data point of  2
  • 3 data points of 4
  • 1 data point of 6
  • 1 data point of 8
  • 1 data point of 10

Because the most frequent value is 4, the mode is 4.
