Brian wants to buy a motorcycle and is planning to get motorcycle insurance. Suppose the average accident rate is 0.1, and the average expenses incurred on accidents is $38,000. The insurance plan has a yearly premium of $1,000 and a deductible of $4,000.
If after 4 years of insuring 100 people, 9 motorcycle drivers had an accident, where does the company stand after money has been taken in and paid out for this group of 100 insured people?

$85,500
-$36,000
$94,000
$58,000

Answers

Answer 1
It's $94,000
 
1,000 X 100 X 4 = 400,000

Answer 2

Answer:

The correct option is $94,000

Step-by-step explanation:

Yearly premium under the insurance plan = $1,000

Total premium from single motorcycle driver in 4 years = $1,000 * 4 = $4,000

Number of people insured = 100

Total premium collected from 100 motorcycle drivers = $4,000 * 100 = $400,000

Average expenses incurred on accident = $38,000

Deductible = $4,000

Net expenses incurred per accident = $38,000 - $4,000 = $34,000

In 4 years , 9 motorcycle drivers had an accident

Total expenses incurred for accident = $34,000 * 9 = $306,000

Net savings of Insurance Company = total premium - total expenses = $400,000 - $306,000 = $94,000

Hope it helps.

Thank you !!

Which of the following shows of the slope of the line and one point on the line?

A. 6/5 and (-3, 1)
B. 5/6 and (1, -3)
C. 5/6 and (-3, 1)
D. -6/5 and (1, -3)

Answers

Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.

Find f(x) if it is known that f(3k)=3k+7.

Answers

f(3k)=3k +7   Equals    9k+7.  So 9k+7 would be the Answer.

Since f(3k) = 3k+7  (Equation 1)

We have to determine the value of f(x).

That is we have to replace 3k by x,

3k = x

Substituting the value of 3k in equation 1.

So, f(x) = x + 7

Therefore, f(x)=x+7 is the required function.

The big bend national park covers 800,000 acres. Brazos Bend state park covers about 5,000 acres. About how many more acres does Big Bend National Park cover then Brazos Bend state park?

Answers

795,000 I dont totally understand why you asked
this but okay....
Final answer:

Big Bend National Park is larger by approximately 795,000 acres than Brazos Bend State Park. This figure was obtained by subtracting the area of the Brazos Bend State Park from the area of the Big Bend National Park.

Explanation:

The Big Bend National Park and the Brazos Bend State Park have a substantial difference in size. You can calculate this size difference by performing a simple subtraction operation. In this case, the size of the Big Bend National Park is 800,000 acres, whereas Brazos Bend State Park covers about 5,000 acres. By subtracting the size of Brazos Bend State Park from the size of the Big Bend National Park, we will get about 795,000 acres, which represents the size difference.

So, the formula would appear as follows:
800,000 acres (Big Bend National Park) - 5,000 acres (Brazos Bend State Park) = 795,000 acres difference.

Cheryl used 40% of her money to buy a dress and 1/5 of the remainder to buy a pair of shoes. She then donated $60 to charity and had $132 left How much money did Cheryl have at first?

Answers

Let the amount be a
Amount used for dress= 40% of a

amount used for shoe= 1/5*60a/100=3a/25
left=60a/100-12a/100=48a/100
=>48a/100-60=132
=>a=192*100/49=400
She had $400 at first.
Hope I helped, good luck.

Let the amount of money she has at first be x.

Dress = 40% x = 0.4x

Amount left = x - 0.4x = 0.6x

Shoes = 1/5 x 0.6x  = 0.12x

Amount left = 0.6x - 0.12x = 0.48x

Donated $60 and had $132 left:

Solve x:

0.48x - 60 = 132

0.48x = 192

Kristen invests $5,745 in a bank. The bank pays 6.5% interest compounded monthly. How long must she leave the money in the bank for it to double? Round to nearest tenth of a year.

Answers

To solve this we are going to use the compounded interest formula: [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where
[tex]A[/tex] is the final amount 
[tex]P[/tex] is the initial investment
[tex]r[/tex] is the interest rate in decimal form 
[tex]t[/tex] is the time in years 

We know that initial investment is $5,745, so [tex]P=5745[/tex]. We also know that Kristen wants his investment to double, so [tex]A=2*5745=11490[/tex]. Now, to convert the interest rate to decimal form, we are going to divide the rate by 100%: [tex]r= \frac{6.5}{100}=0.065 [/tex]. Since the interest is compounded monthly, it is compounded 12 times per year: therefore, [tex]n=12[/tex]. Now that we have all the information we need, lets replace the values in our formula and solve for [tex]t[/tex]:
[tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
[tex]11490=5745(1+ \frac{0.065}{12})^{12t} [/tex]
[tex] \frac{11490}{5745} =(1+ \frac{0.065}{12})^{12t}[/tex]
[tex]2=( \frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=ln(\frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=12tln(\frac{2413}{2400} )[/tex]
[tex] \frac{ln(2)}{12ln(\frac{2413}{2400} )} =t[/tex]
[tex]t=\frac{ln(2)}{12ln(\frac{2413}{2400} )}[/tex]
[tex]t=10.7[/tex]

We can conclude that she must leave the money for 10.7 years in the bank for it to double.

Solve the equation (x-5)1/2+5=2

Answers

The first thing we are going to do for this case is to rewrite the equation correctly:
 ((x-5) ^ (1/2)) + 5 = 2
 Clearing x we have:
 (x-5) ^ (1/2) = 2-5
 (x-5) ^ (1/2) = -3
 x-5 = root (-3)
 x-5 = i * root (3)
 x = 5 + i * root (3)
 Answer:
 The value of x is given by:
 x = 5 + i * root (3)
(x - 5)1/2 + 5 = 2 
(x - 5)1/2 + 5 - 5 = 2 - 5
(x - 5)1/2 = -3
1/2x - 2.5 = -3
1/2x - 2.5 + 2.5 = -3 + 2.5

The functions have the same initial value is correct

"The functions have the same rate of change" is wrong because as we can see, the table goes up by 10, however, the graph goes up by 15

"Both functions are the same" is also wrong, we already proved they have a different slope, how could they possibly be the same?

"The rate of change for Tour 1 is greater" is also wrong because tour 2 goes by 15, which is greater than 10.

"The functions have the same initial value is correct because as we can see on the graph(tour 2), the y-intercept is 35, using the slope on the tab;e(tour 1) we can calculate that when x is 0, the y-value is 35, which means both of the tours has a y-intercept of 35, therefore, this is the correct choice

It's possibly "The functions have the same rate of change."

Explanation: Alright let's do answer of elimination. It cannot be "Both functions are the same" Due to the fact that for one person in Tour 1 is 45 dollars while for Tour 2 is 50. It cannot be "The functions have the same initial value. Since for initial value it's kind of like a constant. For example for 1 person it would be 20 dollars for 2 it would be 40 and so on. It cannot be the last one since  rate of change is obviously different. I don't think I have to go into that.

It all depends on the speeds of the cars. If they are going the same speed, the lines could never cross. Or they could could cross once, if one car passes the other. 
However, if the speeds are changing, then there could be multiple solutions.

Answer:

The lines would only cross ONCE. So the answer is ONE.

Evelyn's scores: 125, 137, 138, 145, 145. Median is 138. 

The median from Evelyn's scores is greater than the median from Robin's. Therefore, the medians do NOT support the conclusion that Robin is winning the game. 

Answer:

The median score for Robin is 107. The Median Score of Evelyn is 138. The medians are the same as the means, so the same conclusion that Robin is winning will be drawn.

The larger the standard deviation, the more spread out the data values will be. A smaller standard deviation, and the values are more closely grouped together. The variance is equal to the standard deviation squared. In terms of symbols
V = s^2
where V = variance and s = standard deviation
So the variance can also be used to determine how grouped or spread out the data values are

------------------------------------------

The z score tells us where this score is located in terms of the group. If the z score is positive, then it is above the mean. If the z score is negative, then it is below the mean. The further the z score is from zero, the further the raw score is from the mean. A score of z = 0 is right at the mean.
