For number 3 it's 4/8, so all you have to do is multiply/divide the bottom, and the same thing you multiply the bottom by you do to the top. It's a bit confusing so I hope this website helps: https://www.mathsisfun.com/equivalent_fractions.html

The mean height of the basketball players is 80.3 inches

For given question,

we have been given the list of heights, in inches, for a sample of college basketball players.

We need to find the mean height of the basketball players.

We know that, for given sample of data

mean = sum of all observations ÷ total number of observation

First we find the sum of given heights.

78 + 83 + 82 + 78 + 78 + 80+ 81 +79+ 79 +83+ 77 +78+ 84+ 82+ 80+ 80 +82+ 84+78+ 80 = 1606

Total number of observations = 20

Using the formula of mean,

⇒ mean height = 1606/20

⇒ mean height = 80.3 inches

Therefore, the mean height of the basketball players is 80.3 inches

71 cards 5 cards in each box 71 ÷5 with leftover How many boxes are needed for all the cards

Fofino [41]

Answer:

15 boxes

Step-by-step explanation:

Because 71 divided by 5 equals to 14.2, you know that you need at least 14 boxes. However, you cannot have 14.2 boxes, because that implies that you have a fifth of a box, which cannot happen. But because each box can only hold up to 5 cards max, you need to get a 15th box for the last card.
