For the first section, divide the bottom number into the top number. The lowest whole number you get will be the big number on the outside. The remaining numbers will be in the numerator. For example, in a for the first section, I divided 4 into 5. Four only goes into five once equally, so the big number would be one. To reach five, just add one more to the numerator to get 1 1/4.

For the second section, just multiply the big number into the denominator, then add the numerator. For example, in a of the second section, I multiplied 2 times 2, giving me 4. The numerator is 1, so adding it to 4 gives me 5, making the answer 5/2. Notice how the denominator always stays the same.

Answer:The mean is equal to the median.

Step-by-step explanation:

Median is the middle value of a given data set. In a symmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.

Step-by-step explanation:

One possible assignation can be:

from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.

How to assign the numbers?

We assume that in the spinner the probability of landing on each one of the given sections is the same.

So, to simulate a case where 30% of the students buy lunch in the cafeteria.

We need to assign 3 of the 10 sections to "buys lunch in the cafeteria" and the other 7 sections to "bring lunch from home"

That assignation can be made in any order you want, for example:

from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.
