A coin is flipped eight times where each flip comes up either heads or tails. how many possible outcomes contain exactly three heads?
The total number of possible outcomes containing exactly 3 heads when a coin is flipped eight times where each flip comes up either heads or tails are 56.
There are two possible outcomes i.e. heads and tails when a coin is flipped. If the coin is flipped 8 times, the total number of outcomes will be:-
\(2^8=256\)
We need exactly 3 heads , and hence exactly 5 tails, like
H H H T T T T T
Here H represents heads and T represents tails.
But H and T can come in any combination, for example:-
H T H H T T T T
Hence, total possible outcomes containing exactly 3 heads and 5 tails will be determined using the combinations formula :-
\(^{8}C_{3}=\frac{8!}{3!5!}=\frac{8*7*6*5!}{3*2*5!}=8*7=56\)

The margin of error of a confidence interval is the error from biased sampling methods.a. trueb. false
Margin of error is statistical expressing the amount of a random sampling error in survay results not the error term from biased sampling method. So, correct answer is False.
What is Margin of error ?Margin of error in statistics represents the amount of random sampling error in the survey results. The larger the margin of error, the less confident that the survey results reflect the results of the census of the entire population. It is denoted by E or MOE. It is calculated by dividing the square root of the sample size by the standard deviation of the population. 99% level is the most conservative, 90% level is the least conservative. The sampling error is a statistical error that occurs when the analyst does not select a sample that is representative of the entire data population.
False - Margin of error only account for sample variability (the fact that my sample differs from many others' samples and therefore provides different statistics.

Net Present Value
A project has estimated annual net cash flows of $15,000 for ten
years and is estimated to cost $47,500. Assume a minimum acceptable
rate of return of 20%. Use
The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.
Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.
Net Present Value = 150000 / (1 + 0.20)^10 - 47500
Net Present Value = $67,482.22
Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.

Mr. Ali cut a wooden plank into three parts in the ratio 2:3:8. The longest part was 72 centimeters
Answer:
117 centimeters
Step-by-step explanation:
Since the longest pieces is 72 centimeters and it’s ratio is 8, that means the individual unit of the ratio is 9 (72/8=9). You can multiply each part of the ratio by 9
2x9=18
3x9=27
We already know the third part of the ratio is 72. Add all of it together to get the original length.
18+27+72=117 cm

Which of the following is NOT true in regards to installment loans?
The statement that is NOT true is that installment loans are always a type of secured loan. Thus, option 1 is correct.
What is an installment?Installment can be defined as the part payment in which we can pay our dues in certain parts.
Installment loans are a type of loan that is repaid over a fixed period of time, usually in equal payments, or installments. The borrower is usually charged interest on the outstanding balance, which is included in each installment payment. Here are some statements about installment loans:
Installment loans are a type of secured loan.
Installment loans can be used to finance both personal and business expenses.
Installment loans usually have a fixed interest rate.
Installment loans are usually repaid in equal installments over a fixed period of time.
The statement that is NOT true in regards to installment loans is:
Installment loans are a type of secured loan.
While some installment loans may be secured, such as a car loan where the car is used as collateral, installment loans can also be unsecured. Unsecured installment loans do not require collateral, and instead rely on the borrower's creditworthiness and ability to repay the loan.
Therefore, the statement that is NOT true is that installment loans are always a type of secured loan.

The domain of the function is a semicircle with a radius of 5 and centered at the origin, where y is non-negative.
The domain of a function is the set of all possible input values for which the function is defined. In this case, the function is defined as:
\(f(x,y) = \sqrt{y} + \sqrt{[25 - x^2 - y^2} ]\)
To find the domain of this function, we need to determine the values of x and y that would result in the function producing a real-valued output.
For the square root of y to be real, y must be non-negative. That is, y ≥ 0.
For the square root of [\(25 - x^2 - y^2\)] to be real, we must have:
\(25 - x^2 - y^2 \geq 0\\x^2 + y^2 \leq 25\)
This is the equation of a circle with radius 5 centered at the origin. Therefore, the domain of the function is the set of all points (x, y) that lie inside or on this circle and have y ≥ 0.
In interval notation, we can write:
Domain: {(x, y) |\(x^2 + y^2 \leq 25, y \geq 0\)}
To sketch the domain, we can plot the circle with radius 5 centered at the origin and shade the region above the x-axis. This represents all the valid input values for the function. The boundary of the domain is the circle, and the domain includes all points inside the circle and on the circle itself, but not outside the circle.

Answer:
-7
Step-by-step explanation:
We are given the following sequence:
\( \displaystyle \large{6,5,4,3,2,...}\)
Checking if the sequence is arithmetic by using the following formula:
\( \displaystyle \large{a_{n + 1} - a_n = d}\)
where d is a common difference. Common Difference means that these sequences must have same difference.
Let's check!
5-6 = -1
4-5 = -1
3-4 = -1
2-3 = -1
Since they are the same, the sequence is arithmetic.
General Term of Arithmetic Sequence
\( \displaystyle \large{a_n = a_1 + (n - 1)d}\)
We know that a1 is 6 since 6 is the first term.
d is -1.
Our goal is to find a14. Therefore,
\( \displaystyle \large{a_{14} = 6 + (14 - 1)( - 1)} \\ \displaystyle \large{a_{14} = 6 + (13)( - 1)} \\ \displaystyle \large{a_{14} = 6 - 13} \\ \displaystyle \large{a_{14} = - 7}\)
Therefore, the 14th term of sequence is -7.
Mia volunteers on the weekend at the Central Library. As a school project, she decides to record how many people visit the library, and where they go. On Saturday, 470 people went to The Youth Wing, 413 people went to Social Issues, and 350 went to Fiction and Literature. On Sunday, the library had 400 total visitors. Based on what Mia had recorded on Saturday, about how many people should be expected to go to The Youth Wing? Round your answer to the nearest whole number
Based on what Mia recorded, we calculate that 152 people are expected to go to the Youth wing on Sunday.
We solve this problem using simple arithmetic methods. According to the data collected by mia,
The number of people who went to the "Youth wing" = 470
The number of people who went to "Social issues" = 413
The number of people who went to "Fiction and Literature" = 350
So, the total number of visitors that the library had on Saturday was,
470+413+350 = 1233
Hence, the proportion of people who went to the "Youth wing", "Social issues" and "Fiction and Literature" are (470/1233), (413/1233), (and 350/1233) respectively.
So, on Sunday the expected number of people who may go to the "Youth wing" should be,
(470/1233)×400
= 152.47 ≈ 152

9. Jackie is an airline mechanic. Her company pays \( 40 \% \) of the \( \$ 3,900 \) annual cost of group health insurance. How much does she pay for it monthly? (4 points)
Jackie pays $130 monthly for her group health insurance.
To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.
First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.
To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.
Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.
