Answer:

To find this out the easy way, add up all the numbers and an answer, then divide by 4.

59 + 64 + 68 + 63.67 = 254.67

254.67/4 = 63.66

A is not correct.

59 + 64 + 68 + 65.25 = 256.25

256.25/4 = 69.25

B is not quite correct.

59 + 64 + 68 + 75 = 266.

266/4 = 66.5

C is not correct.

59 + 64 + 68 + 89 = 280

280/4 = 70.

D.) is the correct answer.

I hope this helps!

Imagine that after washing 5 distinct pairs of socks, you discover that two socks are missing. of course, you would like to have
Whitepunk [10]

solution:

You have only two qualitatively different outcomes possible. Count

the number of ways to get each of the two.

There are just two possible outcomes here: the two missing socks

make a pair (the best case) and the two missing stocks do not make a

pair (the worst case). The total number of different outcomes (the ways

to choose the missing socks) is 10 C 2 = 45.

The number of best-case ones is 5; hence its probability is 5 /45 = 1/9

The number of worst-case ones is 45 − 5 = 40; hence its probability is 40/45 = 8/9.

On average, you should expect 4 • 1/ 9 + 3 • 8 /9 = 28/ 9 = 3 1/ 9 matching pairs.

Which unit would you use to measure the amount of water in a swimming pool?
nataly862011 [7]
If you want to describe the mass of the water in the pool,
then you'll express it in kilograms.

If you want to describe the volume of the water in the pool,
then you'll express it in Liters.

(Those two numbers will be pretty close to equal.)
