Answer:

If twice the opposite of a number increased by five, then the result is the opposite of a number.    

The asiest way to solve this is the guess and check method. It is asking you what a number doubled then by adding five is the opposite of that number. Now go through a few SINGLE digit numbers to try and solve. I hope this helps.

Answer:

a)Both X and Y can be well approximated by normal random variables.

Step-by-step explanation:

For each individual, there are only two possible outcomes. Either they are right-handed, or they are left-handed. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability:

Probability of exactly x sucesses on n repeated trials, with probability p.

The binomial probability can be well approximated by normal random variables, using the expected value E(X) = np and the standard deviation \sigma = \sqrt{np(1-p)}

Let X be the number of males (out of the 100) who are left-handed.

n = 100 and p = 0.13. Can be well approximated.

Let Y be the number of females (out of the 80) who are left-handed.

n = 80 and p = 0.11. Can be well approximated.

The correct answer is

a)Both X and Y can be well approximated by normal random variables.

Find the surface area of a cube<br> with side length 8.5 cm.
EastWind [94]
<h3>Answer:   433.5 square cm</h3>

=========================================================

Explanation:

A cube has 6 identical faces, all of which are squares.

Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.

The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm
