Which of the following exam scores should lead to the better grade? Explain your answer. (4 points)
A score of X = 55 on an exam that has a mean of 60 and a standard deviation of 5.

B. A score of X = 40 on an exam that has a mean of 50 and a standard deviation of 20.

Answers

The lower z-score in scenario B suggests that the score of 40 on the exam with a mean of 50 and a standard deviation of 20 should lead to a better grade compared to the score of 55 on the exam with a mean of 60 and a standard deviation of 5. Option B.

To determine which exam score should lead to the better grade, we need to compare the scores relative to their respective mean and standard deviation.

In scenario A, we have a score of X = 55 on an exam with a mean of 60 and a standard deviation of 5.

In scenario B, we have a score of X = 40 on an exam with a mean of 50 and a standard deviation of 20.

To compare the scores, we can use a statistical measure known as the z-score, which indicates how many standard deviations a particular value is from the mean. The z-score formula is calculated as:

z = (X - mean) / standard deviation

Calculating the z-scores for each scenario:

For scenario A:

z = (55 - 60) / 5

z = -1

For scenario B:

z = (40 - 50) / 20

z = -0.5

The z-score represents the number of standard deviations below or above the mean a score is. In this case, a lower z-score indicates a better performance relative to the mean.

Comparing the z-scores, we can see that scenario A has a z-score of -1, while scenario B has a z-score of -0.5. Therefore, scenario B with a score of X = 40 leads to the better grade.

In scenario B, the score of 40 is closer to the mean of 50 and has a smaller deviation from the mean compared to scenario A. This indicates that the score in scenario B is relatively better than the score in scenario A when compared to their respective distributions. Option B is correct.

In this question, the adjacent angles aren't overlapping, and that they have the shared widely and have the common side. There ABC does have the correct angle, which includes two not overlapping ABD and DBC angles with such a joint B vertex and BD lines. Now it is constructed. Thus both angles are not overlapping:

Answers

Answer:

x = 16

Step-by-step explanation:

First add all of your angles together to get:

9x + 36

Then set that equal to 180:

9x + 36 = 180

Now solve Algebraically:

Subtract 36 from both sides:

9x = 144

Then divide by 9:

x = 16

The reason I set it to 180 is because we know that all triangles angles equal up to be 180° no matter what.

Answers

Are you asking what is b? If so, b would be 7 because 7*8=56. I’m not sure how 448 was an answer? So Harmony is incorrect.

The solution of the equation 8b = 56 is 7. And the solution of Harmony is 448. So, Harmony is incorrect.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

8b = 56

Simplify the equation, then we have

8b = 56

b = 56 / 8

b = 7

The solution of the equation 8b = 56 is 7. And the solution of Harmony is 448. So, Harmony is incorrect.

Help please with steps

Answers

Answer:

[tex]x = 0[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (3,0)[/tex]

[tex](x_2,y_2) = (-3,0)[/tex]

Required

The equation of the perpendicular bisector.

First, calculate the midpoint of the given endpoints

[tex](x,y) = 0.5(x_1 + x_2, y_1 + y_2)[/tex]

[tex](x,y) = 0.5(3-3, 0+ 0)[/tex]

[tex](x,y) = 0.5(0, 0)[/tex]

Open bracket

[tex](x,y) = (0.5*0, 0.5*0)[/tex]

[tex](x,y) = (0, 0)[/tex]

Next, determine the slope of the given endpoints.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{0 - 0}{-3- 3}[/tex]

[tex]m = \frac{0}{-6}[/tex]

[tex]m = 0[/tex]

Next, calculate the slope of the perpendicular bisector.

When two lines are perpendicular, the relationship between them is:

[tex]m_2 = -\frac{1}{m_1}[/tex]

In this case:

[tex]m = m_1 = 0[/tex]

So:

[tex]m_2 = -\frac{1}{0}[/tex]

[tex]m_2 = unde\ fined[/tex]

Since the slope is [tex]unde\ fined[/tex], the equation is:

[tex]x = a[/tex]

Where:

[tex](x,y) = (a,b)[/tex]

Recall that:

[tex](x,y) = (0, 0)[/tex]

So:

[tex]a = 0[/tex]

Hence, the equation is:

[tex]x = 0[/tex]

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

Given:

1,050 calories should be consumed daily for a 105-pound person.

Now, to get the weight of an individual who consumes 1,370 calories per day.

If 1,050 calories should be consumed per day for = 105-pound person.

So, 1 calorie should be consumed per day for =105/1050

                                                                            =1/10                                                                                

Then, 1,370 calories consumed per day for weight of =1370/10

                                                                                         = 137 pounds

Therefore, the weight of an individual who consumes 1,370 calories per day is 137 pound.
