Let's see what it would take to win that trip to Hawaii.
Remember that you think you'll respond to 12 questions and hope to score 600 points to win,
although it's possible to score even more points or many fewer (including negative scores!) on
the show.
Here are the equations you wrote to model your winning scenario:
x+y=12
100x - 200y = 600
Are the boundaries of the first equation viable in the second equation? What does this
suggest about your plan to score 600 points?
Select the two correct statements.
Answers
Answer:
A and D choices (Plato)
Step-by-step explanation:
The upper boundary of the first equation is at x = 12, y = 0. With these values, this is the second equation:
100(12) − 200(0) = 1,200.
The lower boundary of the first equation is at x = 0, y = 12. With these values, this is the second equation:
100(0) − 200(12) = -2,400.
Both of these scores are possible in the game, so they are both viable.
Because the upper boundary is greater than 600, it suggests that you can still score 600 points and win the game even if you get one or two of the questions incorrect.
In fact, you could give 10 correct and 2 incorrect answers to score 600 points and still beat the champion, Kimberly, assuming she answers 15 correct and 5 incorrect to score 500 points.

Which of the following samples will have the smallest value for the estimated standard error?
a. n = 25 with s2 = 100
b. n = 25 with s2 = 400
c. n = 100 with s2 = 100
d. n = 100 with s2 = 400
Answers
Based on the calculations, we find that the sample with the smallest estimated standard error is option c, where n = 100 with s^2 = 100. The estimated standard error for this sample is 1. Therefore, the correct answer is option c.
The estimated standard error is a measure of the variability of the sample mean and is calculated using the sample size (n) and the sample variance (s^2). A smaller value for the estimated standard error indicates less variability in the sample mean.
To determine the sample with the smallest estimated standard error, we compare the combinations of sample size and sample variance provided:
a. n = 25 with s^2 = 100
b. n = 25 with s^2 = 400
c. n = 100 with s^2 = 100
d. n = 100 with s^2 = 400
To calculate the estimated standard error, we take the square root of the sample variance divided by the sample size:
Standard Error = √(s^2 / n)
Comparing the given options, we can calculate the estimated standard errors for each case:
a. Standard Error = √(100 / 25) = √4 = 2
b. Standard Error = √(400 / 25) = √16 = 4
c. Standard Error = √(100 / 100) = √1 = 1
d. Standard Error = √(400 / 100) = √4 = 2

The equation that expresses the relationship between hours and w is w = 90h
Based on the given table, we can observe that the weekly earnings (w) depend on the number of hours worked (h) in a linear fashion.
We can see that for every 10 hours worked, the earnings increase by $90.
Therefore, the equation that expresses the relationship between h and w is w = 90h
This equation states that the weekly earnings (w) are equal to 90 times the number of hours worked (h).

Maximize the value of the function A =6xy subject to x + 2y =24 DO NOT answer any of the following as ordered pairs The maximum value is ___
and it occurs when x = ____ and y = ____
Answers
The function A = 6xy subject to x + 2y = 24. The maximum value is 432 and it occurs when x = 12 and y = 6.
To maximize the value of the function A = 6xy subject to x + 2y = 24, follow these steps:
1. Express one variable in terms of the other using the constraint equation. We can solve for y in terms of x:
x + 2y = 24
2y = 24 - x
y = (24 - x) / 2
2. Substitute the expression for y into the function A:
A = 6x((24 - x) / 2)
3. Simplify the expression:
A = 3x(24 - x)
4. Find the critical points by taking the derivative of A with respect to x and setting it equal to 0:
dA/dx = 3(24 - 2x) = 0
5. Solve for x:
24 - 2x = 0
2x = 24
x = 12
6. Find the corresponding value of y using the expression for y:
y = (24 - 12) / 2
y = 6
The maximum value occurs when x = 12 and y = 6. Now, calculate the maximum value of the function A:
A = 6(12)(6)
A = 432
The maximum value is 432, and it occurs when x = 12 and y = 6.

we repeatedly draw a random card from a standard deck of 52 cards with replacement until we draw a heart or a face card. what is the expected number of times we draw a card?
Answers
The probability of number of times we draw a card is 3.
The probability of drawing a heart or a face card on any given draw.
There are 16 such cards in the deck (4 kings, 4 queens, 4 jacks, and 4 hearts), out of a total of 52 cards. So the probability of drawing a heart or a face card on any given draw is 16/52, which simplifies to 4/13.
Now, to calculate the expected number of draws until we get a heart or a face card, we can use the formula:
Expected number of draws = 1/P(event)
where P(event) is the probability of the event happening. In this case, the event is drawing a heart or a face card, so:
Expected number of draws = 1 / (4/13) = 13/4 = 3.25
So on average, we would expect to draw a card 3.25 times before getting a heart or a face card. However, since we cannot draw a fraction of a card, the actual number of draws will either be 3 or 4.
Hence, the expected number of times we draw a card is 3 (or 4, if the last card drawn is not a heart or a face card).

How did we arrive at these assertions?(I) For N∼B(N, P), where N is a binomial random variable with parameters N and P, the expected value E[N] is indeed equal to Np.
The expected value of a binomial random variable N is given by the formula:
E[N] = Np,
where N represents the number of trials and p is the probability of success in each trial.
(II) For T∼Tn, where T is a Student's t-distribution random variable with n degrees of freedom, the expected value E[T] is not necessarily equal to zero. The expected value of a Student's t-distribution is zero only when the degrees of freedom are greater than one (n > 1).
In general, the expected value of a Student's t-distribution is undefined for n ≤ 1. For n > 1, the expected value is zero.
Therefore, it is important to consider the specific value of n when discussing the expected value of a Student's t-distribution.

LINEAR EQUATION HELPP

The solution to the equation 9(b - 2) = -7 + 0 is b = 11/9.
What is the solution to the linear equation?Given the equation in the question:
9( b - 2 ) = -7 + 0
To solve the equation, first apply distributive property to remove the poarenthesis:
9( b - 2 ) = -7 + 0
9×b + 9×-2 = -7 + 0
9b - 18 = -7 + 0
Next, we simplify the right side of the equation:
9b - 18 = -7
To isolate the variable 'b,' we need to get rid of the constant term (-18) on the left side. We can do this by adding 18 to both sides of the equation:
9b - 18 + 18 = -7 + 18
Simplifying further:
9b = -7 + 18
Add -7 and 18
9b = 11
Now, we want to solve for 'b,' so we divide both sides of the equation by 9:
9b/9 = 11/9
b = 11/9
Therefore, the value of b is 11/9.

dinner is 42%. What is the probability of eating pizza for dinner given that they
buy a new car?
Answers
Answer:
The probability of eating pizza given that a new car is bought is 0.952
Step-by-step explanation:
This kind of problem can be solved using Baye’s theorem of conditional probability.
Let A be the event of eating pizza( same as buying pizza)
while B is the event of buying a new car
P(A) = 34% = 0.34
P(B) = 15% = 15/100 = 0.15
P(B|A) = 42% = 0.42
P(B|A) = P(BnA)/P(A)
0.42 = P(BnA)/0.34
P(B n A) = 0.34 * 0.42 = 0.1428
Now, we want to calculate P(A|B)
Mathematically;
P(A|B = P(A n B)/P(B)
Kindly know that P(A n B) = P(B n A) = 0.1428
So P(A|B) = 0.1428/0.15
P(A|B) = 0.952

What is continuous compounding?
There is no cap on how frequently interest can compound thanks to continuous compounding. A balance can compound continuously an infinite number of times, which means interest is earned on it constantly.
Given:
Lira will not make any further investments in the withdrawals from the account until it is worth $10000.
Suppose that the interest rate for the account is 8.0% , compounded continuously.
We have to find the amount in the account after 20 years.
Consider, the compounded continuously formula
\(P(t)= P_0e^r^t\)
Where
P(t) = Value at time t.
\(P_0\) = Original principle sum = $10,000
r = Interest rate = 8.0% = 0.08
t = time in years = 20
Plug the values in the above formula
\(P(t) = 10000e^0^.^0^8^*^2^0\\P(t) = 49530.32\)
