Answer:

No, you are not correct.

It should look like this:

                              Prefer colorful decorations      Prefer neutral decorations

Pay attention                           20                                                  25

to fashion

Do not pay

attention to                              72                                                      33

fashion

Step-by-step explanation:

33 is 22% of 150. In the question it states that 70% of people do not pay attention to fashion. We need to find the other 48% here. In order to do that we multiply .48 by 150. That gets us 72. To check that answer you can add both 72 and 33 and then divide by 150, which gets 70%.

To get the amount of people that prefer neutral decorations and pay attention to fashion we need to add up 20 + 72 + 33 and that equals 125. Next, we take 150 and minus 125 of it to get 25.

A water tank is currently three-quarters full. If 2500 gallons are drained, the tank will be one-third full. How many gallons of
garri49 [273]

Answer:6000


Step-by-step explanation:3 quarters is equal to 9/12. And 1/3 is equal to 4/12

If it is 9/12 full and 2500 gallons are drained then there are 4/3 left

9/12 - 4/3 is equal to 5/12.

Thta means 2500 gallons is 5/12 of the whole container

5/12 divided by 5 is 1/12

And 2500 divided by 5 is 500

That means every 1/12 of the container can fill 500 gallons

Do then 500 times 12 is 6000



Sorry I am really bad at explaining

Explain the relationship between variance and standard deviation. Can either of these measures be negative? Explain.
jarptica [38.1K]
<span>Standard deviation is the square root of variance. Variance is always a non-negative number, since you can't take the square root of a negative number. So neither can be negative </span>
