The score that should lead to a better grade can be identified by considering the z-scores. The z-score measures how many standard deviations a raw score is above or below the population mean. In this case, a higher z-score indicates a better grade.

To determine which score leads to a better grade, we calculate the z-score for each score using the formula: z = (X - M) / SD. Here's the calculation for each score:

For X = 70:

z = (70 - 92) / 8

z = -2.75

For X = 60:

z = (60 - 72) / 12

z = -1

Comparing the z-scores, we find that a score of X = 70 has a higher z-score (-2.75) than a score of X = 60 (-1). Therefore, the score of 70 should lead to a better grade than the score of 60.

In summary, the score with the higher z-score is the one that should lead to a better grade. In this case, a score of 70 has a higher z-score compared to a score of 60, indicating a better grade for the score of 70.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Given the points K(-2,5), L(1,3) and M(-5, 2p).

If KL is perpendicular to LM. Then we have

The slope of KL will be

KL = (1+2)/(3-5)

KL = -1.5

The slope of LM will be

LM = (1+6)/(3-2p)

LM = 7/(3-2p)

We know the product of the perpendicular lines is a negative one.

        KL x ML = -1

-1.5 x 7/(3-2p) = -1

This exercise introduces the Gamma distribution and asks for the constant 'c' to make the given density function a legitimate probability density function. It also requires proving the relationship Γ(α + 1) = αΓ(α) and computing the expected value and variance of a Gamma-distributed random variable. Finally, using those results, the exercise asks for the expected value and variance of an Exponential-distributed random variable.

The exercise introduces the Gamma distribution, denoted as Gammala

(α, λ), with shape parameter α and scale parameter λ. To determine the value of the constant 'c' to make f(x) a probability density function, we need to ensure that the integral of f(x) over the entire range is equal to 1. This involves using the Gamma function, defined as Γ(α) = ∫[infinity]0 x^(α-1) e^(-x) dx. By setting the integral of f(x) equal to 1 and solving for 'c', we can find the value of 'c' that makes f(x) a legitimate probability density function.

To prove Γ(α + 1) = αΓ(α) for α > 0, we can use integration by parts. By integrating Γ(α) by x and differentiating e^(-x), we can derive a formula that shows the relationship between Γ(α + 1) and αΓ(α). This relationship holds true for all α > 0 and can be demonstrated through the integration by parts technique.

Next, the exercise asks to compute the expected value (E[X]) and variance (Var(X)) of a random variable X following the Gamma distribution. The formulas for E[X] and Var(X) can be derived based on the parameters α and λ of the Gamma distribution.

Finally, using the results from parts (a) and (c), we are required to find the expected value (E[Y]) and variance (Var(Y)) of a random variable Y following the Exponential distribution (denoted as Exp(1)). The Exponential distribution is a special case of the Gamma distribution, where α = 1. By substituting the appropriate values into the formulas derived in part (c), we can compute the desired values for E[Y] and Var(Y).

The two numbers are 7/6 and 5 when the sum of two numbers is 3 more than four times the first number.

Let's call the two numbers x and y, where x is the first number and y is the second number.

The problem gives us two equations that relate the two numbers:

\(x + y = 3 + 4x\\y - x = 2y - 10\)

We can substitute the expression for y from equation 1 into equation 2:

\(y - x = 2(3 + 4x) - 10\)

Expanding the right side and simplifying, we get:

\(y - x = 6 + 8x - 10\\y - x = 8x - 4\)

Adding x to both sides:

\(y = 9x - 4\)

Substituting this expression for y into equation 1:

\(x + (9x - 4) = 3 + 4x\)

Expanding and simplifying the right side:

\(10x - 4 = 3 + 4x\)

Subtracting 4x from both sides:

\(6x - 4 = 3\)

Adding 4 to both sides:

\(6x = 7\)

Dividing both sides by 6:

\(x = 7/6\)

Substituting this value of x back into the expression for y:

\(y = 9x - 4 = 9 * (7/6) - 4 = 63/6 - 4 = 9 - 4 = 5\)

So the two numbers are 7/6 and 5.

Answer:

(c) y = 3x - 16 or y - 2 = 3(x - 6)

Step-by-step explanation:

To be perpendicular, the slope must be the negative inverse of the other line,

so we know the slope must be -(-3/1) = 3

then the general point-slope form is

y = mx + b (m = slope and b = y-intercept) so

y = 3x + b (then use the point given (6,2) to find m)

2 = 3(6) + b

2 = 18 + b

2 - 18 = b

-16 = b

then

y = mx + b

y = 3x - 16

The statement that a box plot graphically shows the 10th and 90th percentiles is False.

A box plot is a graphical representation of a data set that displays key summary statistics, such as the median, quartiles, and potential outliers. It is also known as a box-and-whisker plot. The statement that a box plot graphically shows the 10th and 90th percentiles is False.

In a box plot, the box represents the interquartile range (IQR), which contains the middle 50% of the data. The lower and upper quartiles, representing the 25th and 75th percentiles respectively, are marked by the lower and upper edges of the box. The median, or the 50th percentile, is represented by a line or another symbol within the box.

While the box plot provides information about the spread of the data, it does not directly show the 10th and 90th percentiles. However, by extending the whiskers, which represent the range of the data, you can get a sense of the minimum and maximum values. The whiskers typically extend to the most extreme data points that are within a certain range, such as 1.5 times the IQR.

So, in summary, a box plot does not explicitly show the 10th and 90th percentiles, but it does provide information about the range of the data, which can give you an idea of the overall distribution.

=============================================

Explanation:

The dot plot indicates we have this data set: {20, 23, 25, 28}

So the arithmetic mean is 24.

Determined by various factors such as sample size, statistical significance, and the chosen level of confidence. the probability that the test will fail to decide that the true value is 72.5 when it is indeed 72.5.  

In order to calculate the probability of a Type II error, one would need to know the specific details of the test being used, such as the sample size, the statistical power of the test, and the chosen level of significance.

In general, the probability of a Type II error increases as the sample size decreases and the level of significance decreases. This means that if the test being used is not sufficiently powered or if the level of confidence is too low, there is a higher probability of failing to detect a true effect.

If the test is not able to accurately determine if the statement is true or not when the actual value is 72.5, then there is a possibility that a Type II error has occurred. The probability of this error depends on the specific details of the test being used and cannot be determined without further information.

The probability of a test failing to decide a certain hypothesis is true, when it is actually true, can be determined using the concept of Type II error or false negative rate. In statistical hypothesis testing, Type II error (β) refers to the probability of failing to reject a false null hypothesis. These factors influence the power of the test, which is the probability of correctly rejecting the null hypothesis when it is false. The power of the test (1 - β) is complementary to the probability of making a Type II error.

In this case, the null hypothesis (H0) could be that the value is not equal to 72.5,

while the alternative hypothesis (H1) states that the value is equal to 72.5.

The probability you are looking for is the Type II error rate when the true value is 72.5.

The natural logarithm function is ln(p) = ln(100) - 0.35t

From the question, we have the following parameters that can be used in our computation:

The table of values

The function can be represented as

p = ae^kt

Using the points on the table, we have

ae^(k * 0) = 100

So, we have

a = 100

This gives

p = 100e^kt

Using another point, we have

70.5y = 100e^(k * 1)

70.5y = 100e^k

So, we have

e^k = 0.705

Take the natural logarithm of both sides

k = ln(0.705)

k = -0.35

The function becomes

p = 100e^(-0.35t)

Take the natural logarithm of both sides

ln(p) = ln(100) - 0.35t

Hence, the function is ln(p) = ln(100) - 0.35t

For A, I first subtracted -4 from -7 as their variables are the same. I cannot subtract integers from variables. Then, I added 4 on both sides to move the integer on the left side. (This would also remove the -4 on the right side because -4+4=0) Then I divided -11 by both sides to get 1a or a.

For B, I  subtracted -4 from 1 as their variables are the same. This time, since they are both negative numbers, I can make them both positive. So, just divide 3 by both sides as we want to get 1m.

For C, Add 3 to 8 as v is their variable. Then, I added 3 to both sides because we want to get the variable on one side. Divide by 11 and you will get v=1.
