Answer:

This explanation is not correct

Explanation:

Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.

If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.

The significant level, α = 0.05 level specifies a probability of the correctness of the null hypothesis.

Reasons:

The significant level specifies the the likelihood of rejecting a true null

hypothesis, such that a 5% significance level indicates that the risk of

drawing a conclusion that there is a difference in a sample, when the

samples are similar is 5%, and therefore, the probability that null

hypothesis is true is 5% or 0.05.

The level of significance is a specification that indicates the amount of

evidence required within a sample to allow the rejection of the null

hypothesis, and reach a conclusion that the observed effect is statistical

significant at the α = 0.05 level.

Therefore;

The statement by the student that "This means that the probability that the null hypothesis is true is less than 0.05" is correct.

Option D

Step-by-step explanation:

Set of data in terms of ordered pairs represents a function when output value of each input value is different.

Option A

Since, for every value of x there is a different value of y, it's a function.

Option B

In each ordered pair, for every value of x there is a different value of y.

Therefore, it's a function.

Option C

From the given graph, for every value of x there is a different value of y.

Therefore, it's a function.

Option D

From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).

Therefore, the given set of ordered pairs doesn't represent a function.

Option D is the answer.

Answer:

3.3 PB

Step-by-step explanation:

It is given tat the population of the U.S = 326,891,705 people.

Population expected to use the app in first 4 months = 1/10 of 1%

Storage capacity of an user is = 10 GB

Therefore,

[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%

               = 0.001

The user content = 0.001 x 326,891,705

                            = 326891.705 users

10 GB storage per user.

Therefore,

Size =   326891.705 x 10

       =  3268917.05 GB

       = 3.26 PB

Hence size of the minimum storage would be 3.3 PB.

Therefore:

Combine like terms and subtract:

58° + x° = 180°

x = 180° - 58°

Answer:

  18 feet

Step-by-step explanation:

The ladder length represents the hypotenuse of a right triangle with a base of 9 and an unknown height (h). We can find that height by using the Pythagorean theorem.

  9² +h² = 15²

  h² = 225 -81 = 144

  h = √144 = 12

So, the ladder extends 12 feet up the side of the building. That is the height of the roof. The top of the flagpole is 6 feet above that, so the top of the flagpole is ...

  12 ft + 6 ft = 18 ft

above the ground.

The height to the top of the flagpole is 18 feet.

The equations which have slope 1/4:

ii.  (y - 3.5) = 0.25(x - 2.75)

iii.  5x - 20y = 32

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope.

I. y = x - 5 is in slope-intercept form, so we can see that its slope is 1.

II. (y - 3.5) = 0.25(x - 2.75) can be rewritten in slope-intercept form as y = 0.25x + 2.1875. Therefore, its slope is 0.25 or 1/4.

III. 5x - 20y = 32 can be rewritten in slope-intercept form as y = (1/4)x - (4/5). Therefore, its slope is 1/4.

IV. 5x + 20y = 32 can be rewritten in slope-intercept form as y = (-1/4)x + (4/5). Therefore, its slope is -1/4.

So, only equations II, and III have a slope of 1/4.
