Answer:
x = 0
Step-by-step explanation:
An inequality x > -3 is plotted on a number line by an arrow starting from a point x = -3 and directed towards infinity.
Which shows that all the points which lie on the arrow or on the number line will be greater than x = -3
In this question we have to plot another point indicating x > -3.
Since, x = 0, x = 1, x = 2 are the points which are greater than -3.
Therefore, x = 0 will be the answer.

Explanation:
We start with x = 15 as shown in the first line.
The second line says "repeat the stuff in the curly braces until we reach x = 11". So either we reach x = 11 and that's our answer, or we're stuck in this loop infinitely. Luckily, it only takes one step to get out of this loop since 15-4 = 11. I subtracted off 4 because of the stuff in the curly braces.
So because we reach x = 11, we're able to break out of the loop and the program will display 11 as the final answer. The value 15 is never shown on screen to the user. So if they don't have access to the code, then they'll never see "15".

a racing car consumes a mean of 101 gallons of gas per race with a variance of 49 . if 43 racing cars are randomly selected, what is the probability that the sample mean would differ from the population mean by greater than 2.4 gallons? round your answer to four decimal places.
The probability that the sample mean would differ from the population mean by greater than 2.4 gallons
To solve this problem, we need to use the central limit theorem and the formula for the standard error of the mean:
Standard error of the mean = standard deviation / square root of sample size
In this case, the standard deviation is the square root of the variance, which is 7. Therefore, the standard error of the mean is:
Standard error of the mean = 7 / square root of 43 ≈ 1.061
Next, we need to calculate the z-score for a difference of 2.4 gallons:
z-score = (sample mean - population mean) / standard error of the mean
z-score = (101 - 101.6) / 1.061 ≈ -0.566
Note that we subtract the population mean from the sample mean because we want to know how much the sample mean differs from the population mean.
Finally, we can use a standard normal distribution table (or a calculator) to find the probability that a z-score is less than -0.566 or greater than 0.566 (since the distribution is symmetric). The probability of a z-sitcore less than -0.566 is approximately 0.2881, so the probability of a z-score greater than 0.566 is also approximately 0.2881. Therefore, the probability that the sample mean would differ from the population mean by greater than 2.4 gallons is:
Probability = 0.2881 + 0.2881 ≈ 0.5762
Rounding to four decimal places, the answer is 0.5762.

Matthew wants to take out a loan to buy a car. He calculates that he can make repayments of $35,000 per year. If he can get a six-year loan with an interest rate of 9.25%, what is the maximum price he can pay for the car?
The maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.
To determine the maximum price Matthew can pay for the car, we need to consider his repayment capability and the terms of the loan.
Matthew can make annual repayments of $35,000. Since the loan term is six years, the total amount he can repay over the loan period is $35,000 multiplied by six, which equals $210,000.
To calculate the maximum price of the car, we need to account for the interest rate of 9.25%. The interest rate represents the cost of borrowing and is applied to the loan amount.
Let's assume the loan amount is denoted by P.
The formula to calculate the future value of a loan with interest is:
FV = P(1 + r)^n
Where:
FV = Future value (total amount repaid)
P = Principal amount (maximum price of the car)
r = Interest rate per period (9.25% or 0.0925)
n = Number of periods (six years)
Since Matthew can repay a total of $210,000 over the loan period, we can set up the equation:
$210,000 = P(1 + 0.0925)^6
Now we can solve for P:
P = $210,000 / (1 + 0.0925)^6
Evaluating this expression, we find:
P ≈ $126,318.29
Therefore, the maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

In how many ways could you choose 3 side dishes from a menu that offers 5 vegetable side dishes
and 3 starches if you want at least one vegetable and one starch?
Using the Fundamental Counting Theorem, it is found that there are 90 ways to choose the three side dishes.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with \(n_1, n_2, \cdots, n_n\) ways to be done, each thing independent of the other, the number of ways they can be done is:
\(N = n_1 \times n_2 \times \cdots \times n_n\)
In this problem:
For the vegetable, there are 5 options, hence \(n_1 = 5\).For the starch, there are 3 options, hence \(n_2 = 3\).The remaining dish is free, which means that there are 5 + 3 - 2 = 6 options, hence \(n_3 = 6\).Then:
N = 5 x 3 x 6 = 90.
There are 90 ways to choose the three side dishes.

The mean of four numbers is 30. If three of the numbers are 12, 50, and 48, what is the fourth number?
A. 120
B. 10
C. 12
D. 30
Answer:
Here’s the answer:
Step-by-step explanation:
The sum of the four numbers divided by 4 is equal to the mean.
the sum/4 = mean
(12 + 50 + 48 + n)/4 = 30
(110 + n)/4 = 30
(110 + n) = 30 × 4
(110 + n) = 120
n = 120 - 110

A club has 200 members, 45 of whom are lawyers, 38 of the memebres are liars, while 132 are neither lawyers nor liars. What is the probability that if a random person is randomly chosen from the group of lawyers, the person will be a liar?
The probability that if a random person is chosen from the group of lawyers, the person will be a liar is 38/45, or 0.84.
As a fraction: The probability is given as 38/45, which means that out of 45 people chosen randomly from the group of lawyers, 38 of them are expected to be liars.
As a decimal: To express the probability as a decimal, we divide the numerator (38) by the denominator (45):
38 ÷ 45 ≈ 0.8444444444444444
Rounded to two decimal places, this would be approximately 0.84.
As a percentage: To express the probability as a percentage, we multiply the decimal form by 100:
0.8444444444444444 * 100 ≈ 84.44%
Rounded to two decimal places, this would also be approximately 84.44%.
So, the probability that if a random person is chosen from the group of lawyers, the person will be a liar can be expressed as 38/45 as a fraction, approximately 0.84 as a decimal, or approximately 84.44% as a percentage.
This can be expressed as a fraction, decimal, or percentage, whichever is more helpful.

Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20
And -4x + 5y is indeed 20, so the answer is infinitely many solutions.

One diagonal of a kite is half as long as the other diagonal. If the area of the kite is 188 square inches, what are the lengths of the diagonals?
The length of the longer diagonal is approximately 27.4 inches, and the length of the shorter diagonal is half of that, which is approximately 13.7 inches
To find the lengths of the diagonals of the kite, we can set up an equation using the given information.
Let's call the length of the longer diagonal "d" and the length of the shorter diagonal "d/2".
The formula for the area of a kite is (1/2) * d1 * d2, where d1 and d2 are the lengths of the diagonals.
We are given that the area of the kite is 188 square inches, so we can set up the equation:
(1/2) * d * (d/2) = 188
To solve for the lengths of the diagonals, we can multiply both sides of the equation by 2 to get rid of the fraction:
d * (d/2) = 376
Simplifying the equation, we have:
d^2/2 = 376
Multiplying both sides by 2 to get rid of the fraction, we get:
d^2 = 752
Taking the square root of both sides, we find:
d ≈ 27.4
Therefore, the length of the longer diagonal is approximately 27.4 inches, and the length of the shorter diagonal is half of that, which is approximately 13.7 inches.

Most married couples have two or three personality preferences in common. A random sample of 379 married couples found that 134 had three preferences in common. Another random sample of 573 couples showed that 215 had two personality preferences in common. Let Pi be the population proportion of all married couples who have three personality preferences in common. Let p2 be the population proportion of all married couples who have two personality preferences in common. (a) Find a 90% confidence interval for pi -p2. (Round your answers to three decimal places.) lower limit upper limit (b) Examine the confidence interval in part (a) and explain what it means in the context of this problem. Does the confidence interval contain all positive, all negative, or both positive and negative numbers?
a)The sample sizes are n1 = 379 and n2 = 573. The Z-score for a 90% confidence level is approximately 1.645.
b)The confidence interval contains both positive and negative numbers, it means that the true difference between the population proportions can be either positive or negative.
(a) To find the 90% confidence interval for pi - p2, we can use the formula:
CI = (p1 - p2) ± Z * sqrt((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))
where p1 is the proportion of couples with three preferences in common, p2 is the proportion of couples with two preferences in common, n1 is the sample size for couples with three preferences in common, n2 is the sample size for couples with two preferences in common, and Z is the Z-score corresponding to a 90% confidence level.
From the information provided, p1 = 134/379 = 0.353 and p2 = 215/573 = 0.375. The sample sizes are n1 = 379 and n2 = 573. The Z-score for a 90% confidence level is approximately 1.645.
Plugging these values into the formula, we get:
CI = (0.353 - 0.375) ± 1.645 * sqrt((0.353 * (1 - 0.353) / 379) + (0.375 * (1 - 0.375) / 573))
Calculating this expression, we find that the lower limit of the confidence interval is -0.047 and the upper limit is 0.029.
Therefore, the 90% confidence interval for pi - p2 is approximately -0.047 to 0.029.
(b) In the context of this problem, the confidence interval in part (a) means that we are 90% confident that the true difference between the population proportions of couples with three preferences in common and couples with two preferences in common falls between -0.047 and 0.029.
Since the confidence interval contains both positive and negative numbers, it means that the true difference between the population proportions can be either positive or negative.
