Answer:

exactly 2

Step-by-step explanation:

Prime numbers, the way I was taught to answer this question, has less than 2 factors. The reason is that 1 is considered a factor. However, I think the definition has changed and a prime has exactly two factors -- 1 and itself. 11 is a prime number: only 11 and 1 will divide into it.

Trevor has a bag of jelly beans. There are 10 red, 15 green, 5 orange, and 5 purple jelly beans in the bag. What is the probabil

den301095 [7]

Answer:

$\frac{2}{119}$

Step-by-step explanation:

We have been given that Trevor has a bag of jelly beans. There are 10 red, 15 green, 5 orange, and 5 purple jelly beans in the bag.

The probability of choosing an orange jelly will be total number of orange jellies over all jellies.

$\text{P(Orange)}=\frac{5}{10+15+5+5}$

$\text{P(Orange)}=\frac{5}{35}$

Now, he again chooses an orange jelly and eats it. Since he already ate 1 orange jelly, so orange jelly left is 4 and total jellies would be 34.

$\text{P(Orange)}=\frac{4}{34}$

Using multiplication rule of probability, we will get:

$P(A\cap B)=P(A)\cdot P(B|A)$

$P(\text{Orange}\cap\text{Orange})= \frac{5}{35}\times \frac{4}{34}$

$P(\text{Orange}\cap\text{Orange})=\frac{1}{7}\times \frac{2}{17}$

$P(\text{Orange}\cap\text{Orange})= \frac{2}{119}$

Therefore, the probability that Trevor randomly chooses 1 orange jellybean, eats it, and then chooses another orange jellybean and eats it would be $\frac{2}{119}$ .

Novay_Z [31]

Answer:

Annabella will save $4950.11 after 2 years.

Step-by-step explanation:

<h3>Given</h3>

Periodic payment P = $200,
Period t = 2 years,
Number of compounds, monthly n = 12,
Interest rate, r = 3.2% = 0.032.

Future value of saving, F

<h3>Solution</h3>

Use periodic compound formula:

$F=P\cfrac{(1+r/n)^{nt}-1}{r/n}$

Substitute the values and calculate:

$F=200\cfrac{(1+0.032/12)^{12*2}-1}{0.032/12} =4950.12$ rounded

Anni [7]

Answer:

431,707

Step-by-step explanation:

To figure out the total number, you need to divide the part of the whole by the percentage it is of the whole. This means that you need to divide 35,400 by 8.2%.

Before dividing the percentage, you need to convert it to a decimal.

8.2% = 0.082

Divide the number to find the answer.

35,400/0.082 = 431,707.3

Converted to the nearest whole number, the answer is 431,707.
