Mason sells life insurance policies. He earns a 12 percent commission on every policy he sells. He made the following sales this

scZoUnD [109]

Answer: Mason made $185.00

Step-by-step explanation:

For the first 10 suits he made $12.50 each suit, then he made $20 for the additional 3. (Just ignore the "suits part ._.)

250*.05=12.50

250*.08=20

12.50*10=125

3*20=60

125+60=185.

Refer to matrix A and identify the matrix element a31.

Blizzard [7]

<h3>Answer: D) 7</h3>

===================================================

Explanation:

a31 means "the value in the third row, first column". That value is 7

As another example, a22 = 3 since 3 is in the second row, second column.

Another example: a12 = -1 because we're in the first row and second column.

This is a 3x2 matrix due to it having 3 rows and 2 columns.

About 16 % of the population of a large country is allergic to pollen. If two people are randomly selected, what is the probabil

Vinvika [58]

Answer:

(a) 0.0256

(b) 0.2944

Step-by-step explanation:

For solving this exercise we can apply the binomial distribution. The equation that give as the probability is:

$P(x,n,p)=(nCx)*p^{x} *(1-p)^{n-x}$

Where n is the number of identical events, p is the probability that the event has a success and x is the number of success in the n identical events.

Additionally, nCx is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

So, in this case we have 2 identical events because we are going to select two people randomly and the probability p of success is the probability that the person is allergic to pollen and this probability is 16%.

Then, for the first case, x is 2 because their are asking for the probability that both are allergic to pollen. Replacing the values of x, n and p we get:

$P(2,2,0.16)=(2C2)*0.16^{2} *(1-0.16)^{2-2}$

P(2,2,0.16)=0.0256

For the second case, their are asking for the probability that at least one is allergic to pollen, that means that we need to sum the probability that both are allergic to pollen with the probability that just one is allergic to pollen.

Using the same equation to calculate P(1,2,0.16) we get:

$P(1,2,0.16)=(2C1)*0.16^{1} *(1-0.16)^{2-1}$

P(1,2,0.16)=0.2688

So, the probability that at least one person is allergic to pollen is 0.2944 and it is calculated as:

0.0256 + 0.2688 = 0.2944

State the difference between a bar graph and a histogram.

Lostsunrise [7]

Answer:

Histograms are used to represent a frequency distribution, and bar graph show a comparison between data/variables. Histograms display quantitative data with ranges of the data grouped into bins, whereas bar graphs show categorical data.
