The correct answer is D but i don’t understand

The answer depends on the way you solved it.

I am assuming you take the base on which you perceived to be: . 5 and height which is 2.


So you must've ended with 1

But in actuality, you need to use the equation above and plug in 1.5 and 1
Subtract them and you should get 1.25

Do the same to the other side, you should get 6.

.125 x 6  = .875

Point v is graphed on a number line at -6...point u is 8 units away from v....notice that it doesn't say which way....so it can go either way....so we need to find 8 units away from -6 in both directions

-6 + 8 = 2
-6 - 8 = -14

so point u can be either at 2 or at -14...ur answers are A and D

Answer:

\frac{1}{20}

Step-by-step explanation:

First, we need to look at the # of chips. There are a total of 25, 6 of which are blue.

This means that the chance of getting the first blue chip would be \frac{6}{25}

As there is no replacement, the total number of chips is 24 and there are only 5 blue left. This gives us the chance of \frac{5}{24}

Now all we need to do is mulitply these two and then simplify

\frac{6}{25} *\frac{5}{24} =\frac{30}{600} =\frac{1}{20}
