A university warehouse has received a shipment of 25 printers, of which 10 are laser printers and 15 are inkjet models. If 6 of

Answer:

The probability is 0.31

Step-by-step explanation:

To find the probability, we will consider the following approach. Given a particular outcome, and considering that each outcome is equally likely, we can calculate the probability by simply counting the number of ways we get the desired outcome and divide it by the total number of outcomes.

In this case, the event of interest is choosing 3 laser printers and 3 inkjets. At first, we have a total of 25 printers and we will be choosing 6 printers at random. The total number of ways in which we can choose 6 elements out of 25 is $\binom{25}{6}$ , where $\binom{n}{k} = \frac{n!}{(n-k)!k!}$ . We have that $\binom{25}{6} = 177100$

Now, we will calculate the number of ways to which we obtain the desired event. We will be choosing 3 laser printers and 3 inkjets. So the total number of ways this can happen is the multiplication of the number of ways we can choose 3 printers out of 10 (for the laser printers) times the number of ways of choosing 3 printers out of 15 (for the inkjets). So, in this case, the event can be obtained in $\binom{10}{3}\cdot \binom{15}{3} = 54600$

So the probability of having 3 laser printers and 3 inkjets is given by

$\frac{54600}{177100} = \frac{78}{253} = 0.31$

The height of Mount Kilimanjaro is 19,340 feet.

To convert to scientific notation move the decimal point so there is only 1 digit to the left of the decimal pint, you then multiply that by 10 raised to the number of spaces you moved the decimal point.

19,340 - Move the decimal point 4 places to the left to get 1.9340

You can remove the 0 at the end to get 1.934

You moved the decimal 4 places so raise 10 to 4 and get the final answer:

1.934 x 10^4

The first choice is the correct one.

A stockholder owns 381.881 shares. By the end of the year, he had increased his number of shares by 14.814. What’s the new total

beks73 [17]

Answer:

438.453 shares

Step-by-step explanation:

From my understanding, the question says that the shares were increased by 14.814%.

Therefore, we have to calculate the increase

Step 1: Calculate the increase

Previous shares : 381.881

Increase : 14.814%

Increase = 381.881 x 14.814% = 56.572

Step 2: Calculate the new total shares

New shares = 381.881 + (381.881 x 14.814%)

New shares = 381.881 + 56.572

News shares = 438.453

Therefore, the new total shares owned by the stockholder are 438.453 shares.
