Answer:
Answered below.
Step-by-step explanation:
1) A double - blind study is simply an experiment in which neither the participants nor the people who carry out the experiment know who is receiving any particular treatment. This method is usually used in order to prevent a biased view in research results.
2) True because randomized simply means that subjects were assigned to the group randomly.
3) Placebo - controlled trial simply means that there was a control group that received only a placebo treatment which is mainly designed not to have real effect.

Help please I’m stuck on a few of these
Answer:
27
Step-by-step explanation:
Basically how it works is that the second f() shows an x where the 3 is, so you plug 3 in for x into the equation. 3 squared or 3 to the power of 2 is 9 because 3 x 3 = 9, and 9 times 3 is 27.
Hope this helps!
INVERSE FUNCTIONS
If the f has a power of -1, then it means the inverse, or the opposite of the function, so you can either switch the y and x values in the function, as the f(x) is also used to represent y, while x is x. You can switch the function to x=3y^2.
BUT THIS IS ONLY FOR INVERSE FUNCTIONS OVER AND UP.

Of the entering class at a college, % attended public high school, % attended private high school, and % were home schooled. Of those who attended public high school, % made the Dean's list, % of those who attended private high school made the Dean's list, and % of those who were home schooled made the Dean's list. A student is randomly chosen. a) Find the probability that the student made the Dean's list. b) Find the probability that the student , given that the student made the Dean's list. c) Find the probability that the student , given that the student did not make the Dean's list.
Answer:
(a) The probability that the student made the Dean's list is 0.1655.
(b) The probability that the student came from a private high school, given that the student made the Dean's list is 0.2411.
(c) The probability that the student was not home schooled, given that the student did not make the Dean's list is 0.9185.
Step-by-step explanation:
The complete question is:
Of the entering class at a college, 71% attended public high school, 21% attended private high school, and 8% were home schooled. Of those who attended public high school, 16% made the Dean's list, 19% of those who attended private high school made the Dean's list, and 15% of those who were home schooled made the Dean's list.
a) Find the probability that the student made the Dean's list.
b) Find the probability that the student came from a private high school, given that the student made the Dean's list.
c) Find the probability that the student was not home schooled, given that the student did not make the Dean's list.
Solution:
Denote the events as follows:
A = a student attended public high school
B = a student attended private high school
C = a student was home schooled
D = a student made the Dean's list
The provided information is as follows:
P (A) = 0.71
P (B) = 0.21
P (C) = 0.08
P (D|A) = 0.16
P (D|B) = 0.19
P (D|C) = 0.15
(a)
The law of total probability states that:
[tex]P(X)=\sum\limits_{i} P(X|Y_{i})\cdot P(Y_{i})[/tex]
Compute the probability that the student made the Dean's list as follows:
[tex]P(D)=P(D|A)P(A)+P(D|B)P(B)+P(D|C)P(C)[/tex]
[tex]=(0.16\times 0.71)+(0.19\times 0.21)+(0.15\times 0.08)\\=0.1136+0.0399+0.012\\=0.1655[/tex]
Thus, the probability that the student made the Dean's list is 0.1655.
(b)
Compute the probability that the student came from a private high school, given that the student made the Dean's list as follows:
[tex]P(B|D)=\frac{P(D|B)P(B)}{P(D)}[/tex]
[tex]=\frac{0.21\times 0.19}{0.1655}\\\\=0.2410876\\\\\approx 0.2411[/tex]
Thus, the probability that the student came from a private high school, given that the student made the Dean's list is 0.2411.
(c)
Compute the probability that the student was not home schooled, given that the student did not make the Dean's list as follows:
[tex]P(C^{c}|D^{c})=1-P(C|D^{c})[/tex]
[tex]=1-\frac{P(D^{c}|C)P(C)}{P(D^{c})}\\\\=1-\frac{(1-P(D|C))\times P(C)}{1-P(D)}\\\\=1-\frac{(1-0.15)\times 0.08}{(1-0.1655)}\\\\=1-0.0815\\\\=0.9185[/tex]
Thus, the probability that the student was not home schooled, given that the student did not make the Dean's list is 0.9185.

Convergent or divergent?
Answer:
Convergent
Step-by-step explanation:
This is an alternating series where bn = 2n / eⁿ. Apply the alternating series test:
lim(n→∞) bn
= lim(n→∞) (2n / eⁿ)
Use L'hopital's rule:
= lim(n→∞) (2 / eⁿ)
= 0
For n ≥ 1, the series is decreasing. 2(n+1) / eⁿ⁺¹ < 2n / eⁿ.
Therefore, the series converges.

The question is
"Why would it be beneficial to pay a little more than the required mortgage payment?"
The answer is:
Paying extra on your mortgage means that you make additional payments to your principal loan balance beyond your regular payments. For example, if you pay $1,300 per month normally, you may pay an extra $200 to the principal for a total payment of $1,500. Or if you get a bit of money, say a $5,000 tax refund, you could apply it to your principal loan balance. The faster you pay off your mortgage, the less you will pay in interest, reducing your overall loan cost. However, this option should be considered in the context of your larger financial situation.How much will you save by making extra payments?The amount you can save by making extra mortgage payments is one of the first things you need to figure out as that number will enable you to compare it to other options. Let’s take a look at how much you could save on interest over the life of a 30-year, $200,000 loan with a 3.5% interest rate if you paid $50, $100 and $250 extra each month. Just paying an extra $50 per month will shave 2 years and 7 months off the loan and will save you over $12,000 in the long run. If you can up your payments by $250, the savings increase to over $40,000 while the loan term gets cut down by almost a third.The savings can be substantial. Use a mortgage calculator to figure out your estimated savings. Then, compare that to the savings or returns you can get by investing the same money elsewhere.Ways to prepay your mortgagePay more every monthThe first option is to analyze your budget and see if you can afford to increase the amount you pay on your mortgage each month. Even if you can only commit to $25 or $50, it can save you thousands over the course of the loan.Make an extra payment each year Another option is to make one extra payment each year that is equal to your normal payment amount. This can be a good option if you get a bonus or tax refund each year.Make a lump-sum paymentSometimes situations come about which leave people with a lump sum of money, like receiving an inheritance. While exciting, it can also be stressful because you want to use the money wisely. Using lump sums to pay down your mortgage helps to reduce your interest and increase equity faster, which is a helpful investment. It can also ensure that the money is invested rather than spent.Mix it up You can also use a combination of these approaches, such as paying a little bit more each month and then making a larger one-time payment when you can.
The right payment strategy for you will depend on your financial situation. For example, if your budget is tight and you can’t commit to paying more every month but have certain months when your income is higher, you can commit to making an extra payment during those months. Alternatively, if you don’t receive any income boosts throughout the year but have a little bit of disposable income each month, the monthly payment option will be a better fit.When not to pay extraPaying extra on your mortgage can be helpful but it isn’t always the best use of your money.“Whether you should pay extra on your mortgage or not depends on the rest of your financial picture. If you have credit card debt, an expensive car loan, or other high-interest debt, you’ll want to pay that down before making extra payments on your mortgage,” Matthew McEwan, VP of real estate development and property management firm Medallion Capital Group, said.“Additionally, if you are a savvy investor who can tolerate some risk, you may be able to achieve a higher rate of return by investing that money instead,” McEwan said.What to do before paying off your loan earlyBefore you pay off your mortgage early, there are a few things you should do. For one thing, you’ll want to meet all of your regular necessary expenses (rent, food, clothing, etc.). Next, ensure you pay off any debts you have with interest rates that are higher than the interest rate on your mortgage. For example, if you have a $5,000 balance on a credit card with an 18% APR and your mortgage has a 4% APR, you’ll save more by paying down the credit card first.It’s also recommended to make sure that you have an emergency savings account that is equal to at least three months of pay, and preferably six. Moreover, confirm that you and your dependents are enrolled in the insurance policies you need to protect yourselves in the future. This often includes health, property, auto, disability and life policies.

c
The correct option is (iv)
Step-by-step explanation:
From the question we are told that
The voting options are "Yes, " "No, " "Not sure, " or "Don't care."
The number of people that said is [tex]Y = 636[/tex]
The number of people that said No is [tex]N = 595 [/tex]
The number that indicated Not sure is [tex]S = 93[/tex]
Generally the sample size is mathematically represented as
[tex]n = Y + N + S[/tex]
=> [tex]n = 636 + 595 + 93[/tex]
=> [tex]n = 1324[/tex]
Generally the percentage of responses that was Yes is mathematically represented as
[tex]y = \frac{636}{ 1324} * 100[/tex]
=> [tex]y = 48.03 \% [/tex]
Generally the percentage of responses that was No is mathematically represented as
[tex]m = \frac{595}{ 1324} * 100[/tex]
[tex]m =44.94 \% [/tex]
Generally the percentage of responses that was Not sure is mathematically represented as
