An Expression Is Shown Below Which Statement Is True About The Expression:A) It Is Rational And Equal

Answers

Answer 1

Answer:

B) It is irrational and equal to [tex] = 4\sqrt{2} [/tex]

Step-by-step explanation:

The expression, [tex] \sqrt{18} + \sqrt{2} [/tex] , is an irrational expression because it contains two irrational numbers, [tex] \sqrt{18} [/tex] and [tex] \sqrt{2} [/tex] . Both number are not perfect square. there is no whole number that would be squared that will give you 18 nor 2.

The expression can be equals the following:

[tex] \sqrt{18} + \sqrt{2} [/tex]

[tex] = \sqrt{9*2} + \sqrt{2} [/tex]

[tex] = \sqrt{9}*\sqrt{2} + \sqrt{2} [/tex]

[tex] = 3\sqrt{2} + \sqrt{2} [/tex]

[tex] = 4\sqrt{2} [/tex]

In a random sample of 2,305 college students, 339 reported getting 8 or more hours of sleep per night. Create a 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night. Use a TI-83, TI-83 plus, or TI-84 calculator, rounding your answers to three decimal places.

Answers

Answer:

The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

[tex]n = 2305, \pi = \frac{339}{2305} = 0.147[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 - 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.133[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 + 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.161[/tex]

The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).

The angles in a triangle are such that one angle is 30 degrees more than the smallest angle while the third angle is four times as large as the smallest angle find the measure are of all three angles

Answers

Answer:

25, 55, 100

Step-by-step explanation:

Let's call the smallest angle x, therefore the other two angles would be x + 30 and 4x. Since the sum of angles in a triangle is 180° we can write:

x + x + 30 + 4x = 180

6x + 30 = 180

6x = 150

x = 25°

x + 30 = 25 + 30 = 55°

4x = 25 * 4 = 100°

The sum of angles is 180.

[tex] \alpha + \beta + \gamma = 180 [/tex]

[tex] \alpha + ( \alpha + 30) + (4 \alpha ) = 180[/tex]

[tex]6 \alpha = 150[/tex]

[tex] \alpha = 25 \\ \beta= 25+30=55 \\ \gamma= 4.25 =100[/tex]

A running coach wants to know if participating in weekly running clubs significantly improves the time to run a mile. The running coach collects mean mile times for 42 runners who participate in weekly running clubs with 54 runners who do not run in clubs. The running coach measures times in January and June of the same year. All times are in seconds, and the runners all started with mile times between 8 minutes (480 seconds) and 9 minutes (540 seconds). Here are the results:
January June Change
Mean (seconds) StDev (seconds) Mean (seconds) StDev (seconds) Mean (seconds) StDev (seconds)
Running Club N = 42 530 28 520 23 10 4
Not in a Club N = 54 527 25 519 22 8 3
What is the best method for the running coach to use to determine if participating in weekly running clubs significantly improves the time to run a mile?
A) Use the difference in sample means (530 – 520) in a hypothesis test for a difference in two population means.
B) Use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.
C) Use the sample mean 10 in a hypothesis test for a population mean.

Answers

Answer:

Option B is correct.

Use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.

Step-by-step Explanation:

The clear, complete table For this question is presented in the attached image to this solution.

It should be noted that For this question, the running coach wants to test if participating in weekly running clubs significantly improves the time to run a mile.

In the data setup, the mean time to run a mile in January for those that participate in weekly running clubs and those that do not was provided.

The mean time to run a mile in June too is provided for those that participate in weekly running clubs and those that do not.

Then the difference in the mean time to run a mile in January and June for the two classes (those that participate in weekly running clubs and those that do not) is also provided.

Since, the aim of the running coach is to test if participating in weekly running clubs significantly improves the time to run a mile, so, it is logical that it is the improvements in running times for the two groups that should be compared.

Hence, we should use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.

ga political candidate has asked you to conduct a poll to determine what percentage of people support her. if the candidate only wants a 8% margin of error at a 95% cnofidence level, what size of sample is needed

Answers

Answer: 151

Step-by-step explanation:

if prior population proportion is unknown , then the formula is used to find the sample size :

[tex]n=0.25(\frac{z_{\alpha/2}}{E})^2[/tex]

, where [tex]z_{\alpha/2}[/tex] = Two tailed critical value for significance level of [tex]\alpha.[/tex]

E = Margin of error.

Given : margin of error = 8%= .08

For 95% confidence level , two tailed critical value = 1.96

Now, the required sample size :

[tex]n=0.25(\frac{1.96}{0.08})^2\\\\=0.25(24.5)^2\\\\=150.0625\approx151[/tex]

Hence, the size of the sample needed = 151.

What is 2x-y=6 converted to slope intercept form

Answers

Answer:

y = 2x - 6

Explanation:

* note

the equation provided is written in standard form.

· standard form → Ax + By = C

· slope-intercept form → y = mx + b

To convert the given equation to slope-intercept form, start by subtracting '2x' from both sides of the equation. This will move 'y' to the left side of the equation.

2x - y = 6

2x - 2x - y = 6 - 2x

-y = -2x + 6

Next, multiply both sides of the equation by negative one.

-y = -2x + 6

(-y × -1) = (-2x × -1) + (6 × -1)

y = 2x - 6

Therefore, the given equation should be y = 2x - 6 when converted to slope-intercept form.

The equation is in slope-intercept form, y = 2x - 6, where the slope (m) is 2 and the y-intercept (b) is -6.

Given is an equation of a line we need to convert it into slope-intercept form,

To convert the equation 2x - y = 6 to slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the "y" variable on one side of the equation.

Starting with the given equation:

2x - y = 6

Move the 2x term to the right side by adding "y" to both sides:

2x = y + 6

Rearrange the equation by swapping the sides:

y + 6 = 2x

Move the constant term (6) to the right side by subtracting 6 from both sides:

y = 2x - 6

Hence the equation is in slope-intercept form, y = 2x - 6, where the slope (m) is 2 and the y-intercept (b) is -6.

If 3 measures 123°) what is the measure of 6​

Answers

Answer:

Answer B, 123 degrees

Step-by-step explanation:

Angle 3 and angle 6 are alternate interior angles. This means that, by the Alternate Interior Angles Theorem, they are congruent, and therefore equal.

The pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. The measure of ∠6 is 123°.

What are Alternate Interior angles?

When two parallel lines are intersected by a transversal, the pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. These angles are always equal in measure.

Given that a bridge crosses over the Madison River. The opposite banks of the river are parallel and the bridge is a transversal. Therefore, the measure of the ∠3 and ∠6 will be equal. This is because the two angle are alternate interior angles.

Thus, the measure of ∠6 i,

∠6 = ∠3 = 123°

∠6 = 123°

p ≠ 0.32

This is a two tailed test

Considering the population proportion, probability of success, p = 0.32

q = probability of failure = 1 - p

q = 1 - 0.32 = 0.68

Considering the sample,

Sample proportion, P = x/n

Where

x = number of success = 261

n = number of samples = 750

P = 261/750 = 0.35

We would determine the test statistic which is the z score

z = (P - p)/√pq/n

z = (0.35 - 0.32)/√(0.32 × 0.68)/750 = 1.8

Recall, population proportion, p = 0.32

The difference between sample proportion and population proportion(P - p) is 0.35 - 0.32 = 0.03

Since the curve is symmetrical and it is a two tailed test, the p for the left tail is 0.32 - 0.03 = 0.29

the p for the right tail is 0.32 + 0.03 = 0.35

These proportions are lower and higher than the null proportion. Thus, they are evidence in favour of the alternative hypothesis. We will look at the area in both tails. Since it is showing in one tail only, we would double the area

From the normal distribution table, the area above the z score in the right tail 1 - 0.9641 = 0.0359

We would double this area to include the area in the right tail of z = 0.44 Thus

p = 0.0359 × 2 = 0.07

Since alpha, 0.05 < the p value, 0.07 then we would fail to reject the null hypothesis. Therefore, this is not sufficient evidence to conclude that the actual percentage is different from 32% at the 5% significance level.

Consider a comparison of two models. The "complete" model has both curvature and interaction. The "reduced" model has curvature, but no interaction. You compare the two models using a nested (subset) F-test and determine that you should "reject H0 ". True or False: The reduced model fits the data better than the complete model. Group of answer choicesTrueFalse

Answers

Answer:

True

Step-by-step explanation:

The reduced model and complete are the two models that can be used to determine test the hypothesis. The best way to determine which model fits the data set is to determine the F-test. The Full model is unrestricted model whereas reduced model is restricted model. F-test determines which model to choose for hypothesis testing for better and accurate results.

Need help withGraph a circle

Answers

Step-by-step explanation:

The equation of this circle is:

(x-3)^2 +(y+5)^2 = 16

The equatiin of a circle in general is:

(x-a)^2 +(y-b)^2 = r^2

a and b are the coordinates of the center and r is the radius

● in the given equation: (x-3)^2 + (y+5)^2 = 16

-3 and 5 are the coordinates if the center so start by ploting the center in the point (-3,5)

16 is the radius multiplied by itself

16 is 4×4 so the radius is 4

Take a four unit radius from the center and strat drawing your circle using a compass
