Answer:

3 * 20s

Step-by-step explanation:

In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...

3 * (13.50s + 6.50s)

We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s

3 * 20s

Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = \frac{4}{10}= \frac{2}{5}

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = \frac{3}{9}= \frac{1}{3}

Thus, the probability of picking two white chips will be = \frac{2}{5}* \frac{1}{3}= \frac{2}{15}

Therefore, option B gives the correct answer.

Simplify the expression:<br><br><br><br> 4b - 24 + 19<br><br> 4p - 5p - 30p<br><br> 4.2v - 5 - 6.5v
Licemer1 [7]
For the first expression we will only simplify the constants:

4b - 24 + 19 ——> 4b - 5

The second expression only has variables so we simplify the whole expression

4p - 5p - 30p = -31p


The third expression we will only simplify the variables

4.2v - 5 - 6.5v ——> -2.3v - 5
