4
5
6
7

Answers

The value of y in the given equation is 7.

The given equation is:

2(2y -14)= 0

Bydividing 2 from both the sides, we get:

⇒2y -14= 0

Adding 14 on both the sides, we get;

2y =14

On dividing 2 from both sides, we get;

y=7

Hence, the value of y is 7.

Lines AC and RS are
Coplanar
Parallel
Perpendicular
Skew

Answers

The correct option is Option D: Line AC and RS are skew lines.

What is the line?

A line is defined as set of points that extends infinitely in either direction. A line is the shortest distance between any two points.

What are skew lines?

Skew lines are two lines that never intersect and are not parallel also. Hence we can say that the two lines can not exist in the same plane.

From the figure it is clear that

Line AC and RS are in different planes and they are also not intersecting each other, hence according to the definition of skew lines, they are skew lines.

Step-by-step explanation:

In Juneau, Alaska, the 30-year annual snowfall average is 86.7 inches with a standard deviation of 40.4 inches. The last four years saw an average annual snowfall of 115.7 inches, 62.9 inches, 168.5 inches, and 135.7 inches. Hia performs a hypothesis test on this data to determine if the next 30-year norm will have a different average if the trend from the last four years continues. She uses a significance level of 5%. Which of the following is a conclusion that she may make?a) The z-statistic is 1.44, so the null hypothesis cannot be rejected.
b) he z-statistic is 1.68, so the null hypothesis cannot be rejected.
c) The z-statistic is 1.85, so the null hypothesis should be rejected.
d) The z-statistic is 4.6, so the null hypothesis should be rejected.

Answers

The expected value of the amount of average snowfall for over 30 years is 86.7 inches with a standard deviation of 40.4 inches. To verify if this particular trend continues, we must check the significance value of the amount snowfall for the past four years. Given that the snowfall for past years are as follows: 115.7 inches, 62.9 inches, 168.5 inches, and 135.7 inches. Thus the mean of the sample would be: (115.7 + 62.9 + 168.5 + 135.7)/4 = 120.7 inches. To compute for the z-score, we have z-score = (x – μ) / (σ / √n) where x is the computed/measured value, μ is the expected mean, σ is the standard deviation, and n is the number of samples. Using the information we have, z-score (z) = (120.7 - 86.7) / (40.4/ √4) = 1.68 In order to reject the null hyptohesis our probability value must be less than the significance level of 5%. For our case, since z = 1.68, P-value = 0.093 > 0.05. Therefore, the answer is B.

Step-by-step explanation:

When James spent 10 10 minutes doing push-ups and 40 40 minutes swimming, his fitness app said that he burned 363 363 calories. Similarly, when he spent 40 40 minutes doing push-ups and 180 180 minutes swimming, the app said that he burned 1625 1625 calories. Let � p and � s represent the calories per minute that James burns while doing push-ups and swimming, respectively. Write a system of equations to describe the situation above. Enter the equations below, separated by a comma. How many calories per minute does James burn while doing push-ups? Round your answer to one decimal place. How many calories per minute does James burn while swimming? Round your answer to one decimal place.

Answers

To solve this problem, we need to set up a system of equations based on the given information.
Let's start by defining the variables:
- Let 'p' represent the calories per minute that James burns while doing push-ups.
- Let 's' represent the calories per minute that James burns while swimming.
Based on the first scenario where
James spent 10 minutes doing pushups and 40 minutes swimming, and burned 363 calories, we can set up the equation:
X
10p + 40s = 363
Similarly, based on the second scenario where James spent 40
minutes doing push-ups and 180 minutes swimming, and burned 1625 calories, we can set up the equation:
40p + 180s = 1625

Now, we have a system of equations:
10p + 40s = 363
40p +180s = 1625
To find the values of 'p' and 's', we can solve this system of equations.
By solving the system of equations, we can find the values of 'p' and 's', which represent the calories per minute that James burns while doing push-ups and swimming, respectively.
