The probability the firm will lose money from 10 wells is 0.99 and the probability the firm will gain 1.5 million from the ten wells is 1 minus the CDF of 4 successful wells.
What is the probability the firm will lose or gain money1.
The expected profit from each well is $1 million - $60,000 = $940,000. The expected profit from all ten wells is $940,000 * 10 = $9,400,000. The probability of losing money on all ten wells is 1 - (0.1)^10 = 0.99
2.
To calculate the probability of gaining $1.5 million or more, we can use the cumulative distribution function (CDF) of the binomial distribution, which models the number of successful wells out of ten. The CDF gives the probability of getting a certain number of successful wells or fewer. To get the probability of getting more than a certain number of successful wells, we subtract the CDF of that number from 1. To get the probability of getting 2 or more successful wells, we subtract the CDF of 1 from 1, and so on. To get the probability of getting 5 or more successful wells, we subtract the CDF of 4 from 1, and so on. To get the probability of getting $1.5 million or more, we need to find the probability of getting 5 or more successful wells, since 5 wells at $1 million each give $5 million. The CDF of 4 successful wells can be found using statistical software or by using tables or approximations. The final answer is 1 minus the CDF of 4 successful wells.

If the purchase price for a house is $210,600, what is the monthly payment if you put 20% down for a 30-year loan with a fixed rate of 5%?
The monthly payment for a 30-year loan with a fixed rate of 5% is $702.
How is the monthly payment for a 30-year loan determined?Divide the number of payments you make annually by 30, the length of the loan. For instance, 30 x 12 equals 360. Over the course of the loan, you will make 360 payments.
The following equation is used to determine the down payment: down payment = down payment percentage times purchase price. For the sake of this calculation, the down payment percentage must be converted to a decimal.
Purchase price for a house is $210,600
Down payment is 20%.
remaining payment 80% of total price = $210,600*80/100= $168480.
$168480 payment for a 30-year loan with a fixed rate of 5%
then interest will be
interest = 168480 *5*30/100= $84240
total amount to be paid 30 yr= 168480+ 84240= $252720
amount to be paid per month= $252720/(30*12) = $702.

The values will be Loan amount=$186900, When simple interest is 6% then monthly payment=$1453.66 per month, When simple interest is 7% monthly payment=$1609.4 per month
What is simple interest?Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.
Simple interest formula is given as:
SI=P*R*T/100
Where SI = simple interest
P = principal
R = interest rate (in percentage)
T = time duration (in years)
In order to calculate the total amount, the following formula is used:
Amount (A) = Principal (P) + Simple Interest (SI)
Now,
Initial amount=$237000
Down-payment=20%=20/100*237000=$47400
Amount left=237000-47400=$186900
So, Loan amount=$186900
For interest rate=6%
Total amount=186900+186900*6*30/100
=186900+336420
Total amount=$523320
Therefore, monthly payment=523320/360
monthly payment=$1453.66 per month
For interest rate=7%
Total amount=186900+186900*7*30/100
=186900+392490
Total amount=$579390
Therefore, monthly payment=579390/360
monthly payment=$1609.4 per month

Using simultaneous equations, during the dinner to raise money for a children's museum, 90 tickets were sold.
What are simultaneous equations?Simultaneous equations are two or more equations solved concurrently or at the same time.
Simultaneous equations are also called a system of equations.
The cost of one-person ticket = $200
The cost of two-people ticket = $350
The total number of attendees at the dinner = 130
The total ticket sales = $24,000
Let number of one-person ticket = x
Let number of two-people ticket = 2y
Equations:x + 2y = 130... Equation 1
200x + 250y = 24000... Equation 2
Multiply Equation 1 by 200:
200x + 400y = 26000... Equation 3
Subtract Equation 2 from Equation 3:
200x + 400y = 26000
-
200x + 350y = 24000
50y = 2000
y = 40
x = 130 - 2y

Solve for x. 8x-8+3(2x+2) = -4(x+3)
Answer:
x = - 5/9
Step-by-step explanatiion:
8x-8+3(2x+2) = -4(x+3) is the original equation
Consider each term and simplify
3(2x+2) = 6x + 6
-4(x + 3) = -4x - 12
Therefore the original expression becomes:
8x - 8 + 6x + 6 = -4x - 12
Move -4x to the left side; becomes + 4x
4x + 8x - 8 + 6x = -12
Group like terms on left side and simplify
(4x + 8x + 6x) (-8 +6) = -12
18x - 2 = - 12
Move -2 to right side -> becomes +2
18x = 2 - 12 = - 10
x = -10/18 = - 5/9

a. Use the accompanying graph to determine whether the average cost per ton is increasing or decreasing as the size of the load increases.
b. A company uses trucks with capacities of 9, 16, and 18 tons. What is the average cost per ton for each truck?
erage costq
a. The average cost per ton is increasing as the size of the load increases.
b. For a 9-ton truck, the average cost per ton is $45. For a 16-ton truck, the average cost per ton is $60. For an 18-ton truck, the average cost per ton is $65.
Determine the average cost.This question uses the concept of linear functions.
The equation A(n) = 15n+30 is an example of a linear function, as it is a function of the form f(x) = mx + b, where m is the slope and b is the y-intercept.
The graph of this equation is a straight line, which shows that the average cost per ton is increasing as the size of the load increases.
a. To determine whether the average cost per ton is increasing or decreasing as the size of the load increases, we can look at the graph provided.
The graph shows that as the size of the load increases, the average cost per ton increases.
Therefore, the average cost per ton is increasing as the size of the load increases.
b. To calculate the average cost per ton for each truck, we can use the equation A(n) = 15n+30. For a 9-ton truck, we plug in n = 9 and calculate A(9) = 15(9) + 30 = 135 + 30 = 165. Therefore, the average cost per ton for a 9-ton truck is $45.
For a 16-ton truck, we plug in n = 16 to calculate A(16) = 15(16) + 30 = 240 + 30 = 270.
Therefore, the average cost per ton for a 16-ton truck is $60.
For an 18-ton truck, we plug in n = 18 to calculate A(18) = 15(18) + 30 = 270 + 30 = 300.
Therefore, the average cost per ton for an 18-ton truck is $65.

2 2/3 +2 1/6 as a fraction
Answer:
You can either write it as a whole number: 4 5/6
Or as 29/6
Step-by-step explanation:
Step-by-step explanation:
first step : convert both terms into real fractions (not mixed numbers).
second step : bring both fractions to the same denominator (bottom part).
third step : perform the addition.
1.
2 2/3 = (2×3 + 2)/3 = 8/3
2 1/6 = (2×6 + 1)/6 = 13/6
2.
we bring both fractions to .../6.
remember, we need to do the same multiplication for the numerator and the denominator to keep the overall value of the fraction unchanged.
to get from 3 to 6 we need to multiply by 2.
so,
8/3 = 8/3 × 2/2 = 16/6
3.
16/6 + 13/6 = 29/6
if you want to convert this to mixed numbers, this would be

tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ

Answer: A: 3/10 of the school has blonde hair. B: there are 120 students
Step-by-step explanation: I might have done this wrong but anyway, I multiplied 2/5 by 1/4 and got 1/10, meaning 1/10 of the boys have blonde hair. I multiplied 3/5 (because 5/5 - 2/5 = 3/5) by 1/3 and got that 2/10 of the girls are blonde. I added these, and got that 3/10 of the school are blondes. That's A. Then, I set up the equation 3/10 = 36/x (x equals the total number of students in the school). When I solved it I got x = 120, meaning there are 120 students in the school.

What was the remaining value, in dollars, of the gift card after 20 days? Show or explain how you got your answer.D. How many days in total did it take until the remaining value of the gift
Answer:
A. The original value of the gift card is 75 dollars, which is the y-intercept of the function.
B. The student spent 2.5 dollars each day at the coffee shop, which is the coefficient of n in the function.
C. After 20 days, the remaining value of the gift card is -2.5 * 20 + 75 = 25 dollars.
D. To find the total number of days until the gift card was used up, we need to find when f(n) = 0. Setting the function equal to 0 and solving for n, we get: 0 = -2.5n + 75, so n = (75)/(-2.5) = 30 days.
