Among the given options, +0.79 represents the strongest correlation. D is correct answer.
The r-value, also known as the correlation coefficient, measures the strength and direction of the linear relationship between two variables. It ranges from -1 to +1, where -1 represents a perfect negative correlation, +1 represents a perfect positive correlation, and 0 represents no correlation.
Among the given options, the r-value that represents the strongest correlation is +0.79. This value indicates a relatively strong positive correlation between the two variables being analyzed.
To understand why +0.79 represents a stronger correlation than the other values, let's consider the magnitudes of the correlations:
- -0.83: This represents a strong negative correlation. While it is a strong correlation, its magnitude is slightly smaller than +0.79, indicating that the positive correlation is stronger.
- -0.67: This represents a moderate negative correlation. It is weaker than both -0.83 and +0.79, indicating that both the negative correlation (-0.83) and positive correlation (+0.79) are stronger.
- 0.48: This represents a moderate positive correlation. It is weaker than +0.79, indicating that +0.79 represents a stronger positive correlation.
Therefore, among the given options, +0.79 represents the strongest correlation. However, it is important to note that correlation values alone do not provide information about the causality or the strength of the relationship beyond the linear aspect. Other factors such as the sample size, the context of the data, and potential outliers should also be considered when interpreting the strength of the correlation.

the terminal point p(x, y) determined by a real number t is given. find sin(t), cos(t), and tan(t). 1 5 , − 2 6 5 sin(t) = cos(t) = tan(t) =
Answers
sin(t) = -sqrt(61) / 30, cos(t) = sqrt(61) / 15, and tan(t) = -5/3.
To find sin(t), cos(t), and tan(t) we need to use the coordinates of the terminal point p(x,y) determined by the real number t.
Given that the terminal point is (1/5, -2/6), we can find the values of sin(t), cos(t), and tan(t) using the following formulas:
sin(t) = y / r
cos(t) = x / r
tan(t) = y / x
where r is the distance from the origin to the point p(x,y), which can be calculated using the Pythagorean theorem:
r = sqrt(x^2 + y^2)
Plugging in the values for the coordinates of p(x,y), we get:
r = sqrt((1/5)^2 + (-2/6)^2) = sqrt(1/25 + 4/36) = sqrt(36/900 + 25/900) = sqrt(61/900)
sin(t) = (-2/6) / (sqrt(61/900)) = -sqrt(61) / 30
cos(t) = (1/5) / (sqrt(61/900)) = sqrt(61) / 15
tan(t) = (-2/6) / (1/5) = -5/3
Therefore, sin(t) = -sqrt(61) / 30, cos(t) = sqrt(61) / 15, and tan(t) = -5/3.

Timothy has 72 coins, consisting of quarters, dimes, nickels, and 8 pennies. Samantha comes and takes all of his quarters, takes 3 of his dimes, takes 2 of his nickels, and leaves him with one penny, leaving him with 45 coins. What is the value of quarters that Samantha took?
Can someone explain how to solve this problem?
Answers
Answer:
The total value of quarters that Samantha took is $3.75
Step-by-step explanation:
Timothy has 72 coins.
He has:
Q quarters
D dimes
N nickels
8 pennies.
Then:
Q + D + N + 8 = 72
Samantha takes:
3 dimes
2 nickels
Leaves him with one penny, then she takes 7 pennies.
all of the quarters, so she took Q quarters.
So now Timothy has 45 coins.
And for each particular type of coin, Thimothy now has:
D - 3 dimes
0 quarters
1 penny
N - 2 nickels
And we know that he has 45 coins, then:
(N - 2) + 1 + ( D - 3) = 45
Which we can rewrite as:
N + D + 1 - 2 - 3 = 45
N + D - 4 = 45
N + D = 45 + 4 = 49
So we have two equations:
Q + D + N + 8 = 72
N + D = 49
Now we can replace the second equation into the first one:
(N + D) = 49
then:
Q + D + N + 8 = 72
Q + (D + N) + 8 = 72
Q + 49 + 8 = 72
Now we can solve this for Q
Q = 72 - 49 - 8 = 15
So Samantha took 15 quarters.
Each quarter has a value of $0.25
Then Samantha took:
15*$0.25 = $3.75
The total value of quarters that Samantha took is $3.75

hat is the maximum speed of a point on the outside of the wheel, 15 cm from the axle?
Answers
It depends on the rotational speed of the wheel. To calculate this speed, we need to know the angular velocity of the wheel.
The maximum speed of a point on the outside of the wheel, 15 cm from the axle, if we assume that the wheel is rotating at a constant rate, we can use the formula v = rω, where v is the speed of the point on the outside of the wheel, r is the radius of the wheel (15 cm in this case), and ω is the angular velocity of the wheel. Therefore, the maximum speed of a point on the outside of the wheel would be directly proportional to the angular velocity of the wheel.
The formula to calculate the maximum linear speed (v) is:
v = ω × r
where v is the linear speed, ω is the angular velocity in radians per second, and r is the distance from the axle (15 cm, or 0.15 meters in this case).
Once you have the angular velocity (ω) of the wheel, you can plug it into the formula and find the maximum speed of a point on the outside of the wheel.

Therefore, the answer is B: 1/36.
Answer:
B. 1/36
Step-by-step explanation:
A dice has 6 sides, we are looking to roll a 5, which is just one number, hence 1/6. If you roll two, to find the probability of two independent events (meaning they do not affect each other), you multiply the two together.
1/6 x 1/6 = 1/36

How large must be a test statistic to reject the null hypothesis in favor of alternative hypothesis?
Answers
To determine how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis, we need to first establish a hypothesis test. A hypothesis test is a statistical procedure that helps us determine if there is enough evidence to support a particular hypothesis.
In a hypothesis test, we start with a null hypothesis (H0) which is a statement that there is no significant difference between two groups or variables. The alternative hypothesis (Ha) is the statement that there is a significant difference between the two groups or variables.
Once we have established our null and alternative hypotheses, we need to conduct a statistical test to determine if there is enough evidence to reject the null hypothesis in favor of the alternative hypothesis. The test statistic is the numerical value that we obtain from our statistical test, which we compare to a critical value to determine if we can reject the null hypothesis.
The critical value is determined by the level of significance (α) we have chosen for our test, which is the probability of making a type I error (rejecting the null hypothesis when it is actually true). Typically, the level of significance is set at 0.05 or 0.01.
So, to answer the question, how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis depends on the level of significance we have chosen, as well as the degrees of freedom and distribution of the test statistic. The critical value for a given level of significance and degrees of freedom can be found in statistical tables or calculated using software. If the test statistic is larger than the critical value, we can reject the null hypothesis in favor of the alternative hypothesis.

0 ≤ x < 2, where x is an integer. Option C
The appropriate domain for the function f(x) = 42 - 15x in the given context can be determined by considering the constraints of the problem.
Tyson has a $50 gift card, and he wants to purchase a belt that costs $8 and x number of shirts that cost $15 each. The function f(x) represents the balance on the gift card after Tyson makes the purchases.
The number of shirts Tyson can purchase depends on the remaining balance on the gift card. Since each shirt costs $15, the maximum number of shirts he can buy is limited by the amount of money left on the gift card.
If we subtract the cost of the belt ($8) and the cost of x shirts ($15x) from the initial balance ($50), we should get a non-negative result, indicating that Tyson has enough money on the gift card to make the purchases.
Therefore, we can set up the inequality:
50 - 8 - 15x ≥ 0
Simplifying, we have:
42 - 15x ≥ 0
Now, we can solve for x:
-15x ≥ -42
Dividing by -15 (remembering to flip the inequality sign), we get:
x ≤ 42/15
x ≤ 2.8
Since x represents the number of shirts Tyson can buy, it should be a whole number. Therefore, the appropriate domain for the function f(x) is:
0 ≤ x ≤ 2, where x is an integer.
Option C.

To find the total marks for the test, you can use the following proportion:
percentage score = (marks obtained / total marks) x 100%
Substituting the given values:
52.5% = (42 / total marks) x 100%
Dividing both sides by 52.5:

The weight of corn chips dispensed into a 12-ounce bag by the dispensing machine has been identified as possessing a normal distribution with a mean of 12.5 ounces and a standard deviation of 0.2 ounce. What proportion of the 12-ounce bags contain more than the advertised 12 ounces of chips
Answers
The proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips is 0.
The proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips can be determined by finding the area under the normal distribution curve to the right of the mean.
To find this proportion, we can use the z-score formula:
z = (x - mean) / standard deviation
In this case, we want to find the proportion of bags that contain more than 12 ounces, so x = 12 ounces.
z = (12 - 12.5) / 0.2
z = -2.5 / 0.2
z = -12.5
Next, we need to find the cumulative probability associated with the z-score. We can use a standard normal distribution table or a calculator to find this probability.
Looking up the z-score of -12.5 in the table or using a calculator, we find that the cumulative probability is approximately 0.
Therefore, the proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips is 0.
