A farmer has found that in a typical year they earn $75000 from their harvest. In a wet year they earn $48000, and in a drought they earn $26000. If the probability of a wet year is 0.30 and the probability of a drought is 0.20 find the mean amount this farmer will make from their harvest over a long period of years. If the farmer has the option of buying insurance for $2000 a year that pays $20000 in a year of a drought, does it make sense financially to buy the insurance? Justify.

Answers

Answer 1

Answer:

1. The mean amount that this farmer will earn over a long period of years is:

$57,100

2. It makes sense financially for the farmer to buy the insurance.   In a year of drought, he earns only $5,200.  If he spends on insurance premium, his earnings are reduced by $2,000 to $3,200 but the insurance reimbursement will take his overall net earnings to $23,200 ($3,200 + $20,000).  Incurring the insurance expense is highly justified.

Step-by-step explanation:

Earnings in a typical year = $75,000

Earnings in a wet year = $48,000

Earnings in a drought = $26,000

Pro

                         Typical            Wet           Drought

Earnings          $75,000       $48,000      $26,000

Probability        0.50              0.30             0.20

Expected

 earnings       $37,500       $14,400        $5,200

Mean earnings = $57,100

Insurance expense                                 $2,000

Net earnings after insurance expense $3,200

Insurance Reimbursement                  $20,000

Net earnings                                         $23,200

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 1/4y - 2x = 5. The value of y for the expression is solved as below:-

1/4y - 2x = 5

( 1 / 4 )y = 2x + 5

y = 4 ( 2x + 5 )

y = 8x + 20

Therefore, the value of y for the given expression is y = 8x + 20. The correct option is A.

too young to tat based on a harris poll, among adults who regret getting tattoos, 20% say that they were too young when they got their tattoos. assume that five adults who regret getting tattoos are randomly selected, and find the indicated probability. find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. group of answer choices​

Answers

Answer:

The probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Step-by-step explanation:

Let X denote the number of adults who says that he or she was too young to get tattoos.

The probability of selecting an adults who says that he or she was too young to get tattoos is, p = 0.20.

Five adults who regret getting tattoos are randomly selected.

The events of any of these five adults regretting getting tattoos is independent of each other.

The random variable X follow a Binomial distribution with parameters n = 5 and p = 0.20.

Compute the probability that exactly one of the selected adults says that he or she was too young to get tattoos as follows:

[tex]P(X=x)={5\choose x}(0.20)^{x}(1-0.20)^{5-x}\\\\P(X=1)={5\choose 1}(0.20)^{1}(0.80)^{5-1}\\\\[/tex]

                [tex]=5\times 0.20\times 0.4096\\\\=0.4096[/tex]

Thus, the probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

If M is the midpoint of XY and XM=2x+5 and MY=3x-1, then what is the length of MY?

Answers

Answer:

If M is mid point then XM = MY

2x +5 = 3x -1

2x - 3x = -1 - 5

-x = -6....so

x = 6

MY = 3(6) -1

MY = 18 -1

MY = 17

A triangle has one angle that measures 56∘ and one angle that measures 63∘. The measure of the triangle's third angle is _____ degrees.

Answers

Answer:

61 degrees

Step-by-step explanation:

Let's do this

So we know all the angles measure in a triangle will be 180 degrees

We have 56 and 63

To find the third, let's add and subtract

56+63=119

Now let's subtract from 180

So 180-119=61

The third angle measures 61 degrees

Now let's add them up and see if they total 180 degrees

So 56+63+61=180

Yay, we found the answer!

The answer is 61 degrees.

∴ Alyssa was 48 years old when her horse Midnight died .

Answer:

Step-by-step explanation:

Alyssa was twice the age of midnight so 10 ÷2 =5(age gap)

Midnight died at 24 so Alyssa was 29 that time because

0.5 x 0.5 = 0.25

2(0.9 + 0.9 + 0.25) = 2(1.8 + 0.25) = 2(2.05)

2 x 2.05 = 4.1

Therefore the answer is 4.1

Answer:

Hope it helps.....plz mark as brainliest

Step-by-step explanation:

SA = 2(hl+hw+lw)

 

It doesn't matter which specifically is the height or width or length in this case.

1.8 x 0.5 = 0.9

1.8 x 0.5 = 0.9

0.5 x 0.5 = 0.25

2(0.9 + 0.9 + 0.25) = 2(1.8 + 0.25) = 2(2.05)

2 x 2.05 = 4.1, which is the surface area.

The formula K=59(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.

a. Solve the formula for F.

F= ​

Answers

Answer:

9/5 (K-273.15) + 32=F

Step-by-step explanation:

K=5 /9(F−32)+273.15

Subtract 273.15 from each side

K-273.15=5/9(F−32)+273.15-273.15

K-273.15=5/9(F−32)

Multiply by 9/5 on each side

9/5 (K-273.15)= 9/5 *5/9(F−32)

9/5 (K-273.15)=(F−32)

Add 32 to each side

9/5 (K-273.15) + 32=F−32 +32

9/5 (K-273.15) + 32=F

Answer:

f=1/59k+27.370339

Step-by-step explanation:

k=59(f−32)+273.15

Step 1: Flip the equation.

59f−1614.85=k

Step 2: Add 1614.85 to both sides.

59f−1614.85+1614.85=k+1614.85

59f=k+1614.85

Step 3: Divide both sides by 59.

59f/59=k+1614.85/59

f=1/59k+27.370339

Write an equation of the line shown. Then use the equation to find the value of 2 when y = 185

Answers

Answer:

[tex] y = 15x + 20 [/tex]

x = 11, when y = 185

Step-by-step explanation:

Given:

(0, 20);

(2, 50)

Required:

Equation of the line;

Value of x, when y = 185

SOLUTION:

Equation of the line can be written using the slope-intercept formula, given as, [tex] y = mx + b [/tex].

m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} =\frac{50 - 20}{2 - 0} = \frac{30}{2} = 15 [/tex]

b = y-intercept = the pointt at which the line cuts the y-axis = 20

Plug in the value into the formula to get the equation:

[tex] y = mx + b [/tex]

[tex] y = 15x + 20 [/tex]

Use this equation to solve for x, when y = 185

[tex] y = 15x + 20 [/tex]

[tex] 185 = 15x + 20 [/tex] (substitution)

[tex] 185 - 20 = 15x + 20 - 20 [/tex]

[tex] 165 = 15x [/tex]

[tex] \frac{165}{15} = \frac{15x}{15} [/tex]

[tex] 11 = x [/tex]

x = 11, when y = 185

Graph the line using a point and a slope. Write the equation of each line.
c
a line that contains point (0, −3) and perpendicular to another line whose slope is 2.

Answers

Answer:

Graph attached.

Step-by-step explanation:

Line (i) contains  point (0, -3)It's perpendicular to line (ii) whose slope is 2

The product of slope of line (i) and slope of line (ii) should be equal to -1 (product of slopes of two perpendicular lines = -1)

i.e

Slope of line (i) × 2 = -1

Slope of line (i) = [tex]-\frac{1}{2}[/tex]

To find the equation of line (i), we need another point (x,y) on the line.

Slope (m) = change in y ÷ change in x = [tex]\frac{y - -3}{x - 0} = -\frac{1}{2}[/tex]

y = [tex]-\frac{1}{2} x[/tex] - 3

The answer is "About 421.6 and 578.4 the middle of 95% of both the wires of the A business checked".

Step-by-step explanation:

The Mean = Median = Mode= 500 for company A  

It also will see company A as a regular delivery  

Mean > Median > Mode for the business B  

Company B would seem to have a correct warped delivery

The value of Z varies in the center of 95% of the wires: [tex](-1.96\ \ from \ \ 1.96)[/tex]

[tex]\text{The lower bound} = Mean - 1.96 \times \sigma[/tex]
