On Monday John ate 1/6 of a carton of eggs. If there are 12 eggs in the carton how many eggs are left

Answers

Answer:

12 divided by 6 is 2.

Step-by-step explanation:

There are 12 eggs in the carton, right? So, split the number of eggs into 6 groups. There are 2 eggs in each of the six groups. John eats an entire group of eggs (two eggs). What is twelve minus two?

12 - 2 = 10 eggs left (left behind are 5/6 of the eggs in the carton).

Hope this helps.

the answer is 2 because if you divide 12 by 6 one sixth is equal to 2

Compute the standard deviation for the set of data.
2,5, 6, 8, 14

Answers

Answer:

Step-by-step explanation:

First work out the mean:

Mean = (2 + 5 + 6 + 8 + 14) / 5

= 35/5 = 7.

Now subtract the mean form each of the values:

2 - 7 = -5

5 - 7 = -2

6 - 7 = -1

8 - 7 = 1

7 - 14 = -7.

The squares of these are 25, 4, 1, 1, 49

Their sum = 25 + 4 + 1 + 1 + 49 = 80

Now divide this by 5 = 16.

Standard deviation is √16 = 4.
