Write a paragraph, flowchart, or 2-column proof for the following conjecture:
Given: angle 1 = angle 4
Prove: angle 3 = angle 2

Answers

Answer:

How I would write my paragraph:

If angle 1 is congruent to angle 4, angle 1 must also be congruent to angle 3 by the transitive property. This is because is angle 3 and angle 4 are vertical angles, and they must be congruent. If angle 1 is congruent to angle 3, then the two lines in the middle must also be parallel due to the converse of the corresponding angles theorem. Because the two lines in the middle are parallel, angle 3 must be congruent to angle 2 by the alternate interior angles theorem.

a 95% confidence interval is found to be (24, 30). The sample standard deviation is 7.5, and the sample size is 25. If you wanted a smaller interval what could you do?
A. increase the confidence level to 99.7%.
B. increase the sample size to 36.
C. decrease the sample size to 20.
D. None of these.

Answers

Answer:B. Increase the sample size to 36

Step-by-step explanation:

First of all, the size of the sample must be greater than 30. Then the correct option is B.

What is a normal distribution?

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

A 95% confidence interval is found to be (24, 30).

The sample standard deviation is 7.5, and the sample size is 25.

First of all, the size of the sample must be greater than 30. Then we have to increase the sample size up to 36.

Cara has two pieces of ribbon, one 15 inches long and the other 20 inches long. To decorate an album, she wants to cut them up to produce many pieces of ribbon that are all of the same length, with no ribbon left over. What is the greatest length, in inches, that she can make them?

Answers

Answer:

5 inches

Step-by-step explanation:

Given that :

There are two pieces of ribbon with length:

15 inches and 20 inches

To cut ribbon into equal sizes with no ribbons left ; the greatest length in inches of the ribbon would be :

Calculate the greatest common factor of both lengths : 15 inches and 20 inches

____15___20

_5__ 3___4

OR

Find the factors of 15 and 20 and pick the greatest common to both

15 : 1, 3, 5, 15

20 : 1, 2, 4, 5, 10, 20

Greatest factor common to both = 5

Hence the greatest length she can cut the ribbons into without any leftover is 5 inches

Answers

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

What is the length of AZ?
Use the following information:
A
is between Y
and Z,
YA=22, AZ=16x,
and YZ=166.

Answers

AZ is 144 and x is 9

The required length of AZ for the line segment YZ is 144.

Given that,
A is between Y and Z,

YA=22, AZ=16x, and YZ=166.

What is a line?

The line is a curve showing the fastestdistance between 2 points.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
YZ = YA + AZ
166 = 22 + 16x
16x = 144
x = 9
Now,
Length of AZ = 16x
                   = 16 * 9
                   = 144



Thus, the required length of AZ for the line segment YZ is 144.

The furniture store sells each chair (c) for $225. To have them shipped to their house, the store charges $60. If the Browns bought c number of chairs, how much did they spend (s)?​

Answers

Answer:      s = 225c+60

==========================================================

Explanation:

1 chair = 225 dollars

c chairs = 225c dollars .... multiply both sides by c

This shows that buying c chairs costs 225c dollars

c is a placeholder for a positive whole number

Add on the $60 shipping cost to get the total cost 225c+60

Therefore s = 225c+60

What is the function of the line?

Answers

Answer:

It is a linear function.

Step-by-step explanation:

The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.

To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).

This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.

Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2).  Slope intercept is y=mx+b.

The line of the equation would then be y = -2/3x -2
