Answer:

The given construction is illustrating parallel lines.

Step-by-step explanation:

In the given figure ,

1) Let it be Δ ABC with base BC.

2) Mark point D on side AB.

3) Taking B as point to draw an angle and with same measurement draw an arc at point D.

4) Extend D to join AC at point E such that ∠ ADE = ∠ABC

these are corresponding angles .

Therefore, DE ║ BC

We obtained a line DE parallel to BC.

Thus, the given construction is illustrating parallel lines.

Answer:

For this case since the p value is higher than the significance level we can FAIL to reject the null hypothesis and we can conclude that the true means are NOT significantly different at 10% of significance.

Step-by-step explanation:

Information provided

represent the mean for sample 1

represent the mean for sample 2

represent the sample standard deviation for 1

represent the sample standard deviation for 2

sample size for the group 2

Significance level provided

t would represent the statistic

Hypothesis to test

We want to verify if the true means for this case are significantly different, the system of hypothesis would be:

Null hypothesis:

Alternative hypothesis:

The statistic is given by:

(1)

And the degrees of freedom are given by

Replacing the info given we got:

The degreess of freedom are given by:

Now we can calculate the p value with the following probability:

Angels I need MAJOR HELP

<2 and <3 are supplementary angles...therefore they must equal 180°

since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°

180 - 125 = 55° < answer

hope this helps :)

Kevin wants to buy an area rug for his living room. He would like the area rug to be no smaller that 48 square feet and no bigge

mariarad [96]

Answer:

8-10 feet

Step-by-step explanation:

If the length of the carpet is two more than the width, the width can be expressed as x and the length can be expressed as x+2. This means that the area(x^2+2x) must be greater than 48 but no less than 80.

Now we can solve for both the maximum and minimum cases:

x^2+2x=48, x^2+2x-48=0, now we can factor, (x+8)(x-6)=0, and now we can use the Zero Product Property to find x=-8;x=6. Since we cant have negative width, x at least has to be equal to 6.

x^2+2x=80,x^2+2x-80=0, now we can factor, (x+10)(x-8), and now using the Zero Product Property to find x=-10;x=8, and since it must be positive, at most x can equal 8.

Now since the length is two more than the width, x, you add two to both of these values and get a range of 8-10 feet.
