1: Angles 2 & 6 + angles 3 & 7
- Angles that are on the inside of the parallel lines and on opposite sides of the transversal
2: Angle 1
- Angles in the same position but the other line
3: Alternate exterior angles
- Angles that are on the outside of the parallel lines and opposite sides of the transversal
4: Same side interior angles
- They are on the same side of the transversal and inside the parallel lines
5: Angle 2
- It is supplementary and on the inside of the parallel lines
6: Angle 4
- It is supplementary and on the outside of the parallel lines
7: 146°
- They are corresponding angles, so they are the same measurement
8: 128°
- They are supplementary angles, so 180 - 52 = 128
For 9 & 10:
- They are supplementary, so adding them together will result in 180 degrees
- (8x + 63) + (5x) = 180 -> 8x + 5x + 63 = 180 -> 13x = 117 -> x = 9
- Now we will plug it in to find the individual measurements:
9: 135°
- 8x + 63 -> 8(9) + 63 -> 72 + 63 = 135
10: 45°
- 5x -> 5 (9) = 45

3. Not reversible
4. not revisable
Step-by-step explanation: 1.Likewise, a number is a reversible multiple if the number formed by 2058 is not reversible because 8502/2058 = 4.131, which is not a whole number
2. When rabbits eat carrots you cannot form the carrot back to its original form so that's why its irreversible (not/non revisable)

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hip measurment was 42.3 in with a standard deviation of 1.2 in. As part of a project for a fashion merchandizing class, Mallorie selects a simple random sample of 15 pairs of women's size 16 jeans and records the following hip measurements. in inches. 44.5,43.0, 46.6, 42.9.43.7.43.9.42.4, 43.2, 43.1.44.4.46.1, 44.7,44.4, 43.9,44.7 Mallorie plans to use this data to construct a 99% confidence interval for fe, the mean hip measurement of women's size 16 jeans. She assumes that the hip measurements are normally distributed and that the population standard deviation is 1.2 in. The sample mean, x, is the point estimate for a confidence interval to estimate a population mean. What is the mean hip measurement for the random sample of 15 pairs of women's size 16 jeans? What is the margin of error for Mallorie's confidence interval? Choose the correct interpretation of Mallorie's confidence interval. a. Mallorie is 99% sure that the mean hip measurement of size 8 jeans is between 37.71 in and 38.67 in. b. In 99% of all samples, the sample mean will fall between 37.66 in and 38.73 in. c. There is a 99% chance that the mean hip measurement of size 8 jeans falls between 37.71 in and 38.67 in. d. There is a 99% chance that the mean hip measurement of size 8 jeans falls between 37.66 in and 38.73 in. e. Mallorie is 99% sure that the mean hip measurement of size 8 jeans is between 37.66 in and 38.73 in.
Answers
Using the z-distribution, we have that:
The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.The margin of error is of 0.8 in.The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the sum of all observations divided by the number of observations. Hence:
[tex]\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1[/tex]
The margin of error of a z-confidence interval is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
z is the critical value. [tex]\sigma[/tex] is the population standard deviation. n is the sample size.We have to find the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.
In this problem, [tex]\alpha = 0.99[/tex], thus, z with a p-value of [tex]\frac{1 + 0.99}{2} = 0.995[/tex], which means that it is z = 2.575.
Then, the margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.575\frac{1.2}{\sqrt{15}}[/tex]
[tex]M = 0.8[/tex]
The margin of error is of 0.8 in.
The interval is:
[tex]\overline{x} \pm M[/tex]
[tex]\overline{x} - M = 44.1 - 0.8 = 43.3[/tex]
[tex]\overline{x} + M = 44.1 + 0.8 = 44.9[/tex]
The interpretation is:
Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

Step-by-step explanation:
The arc length of the moon's diameter is ...
s = rθ . . . . . where r is the distance to the moon, θ is the subtended arc in radians, and s is the moon's diameter.
There are 180° in π radians, and there are 60' in 1°. That means there are π/10800 radians in each minute of arc.
s = (60·6300 km)(21/10800π) = 2309 km
The radius of the moon is estimated to be half this diameter, or ...
moon radius ≈ 1155 km

Here is the proof:
We'll assign each angle a letter as following
A B C D with A being the top left and D being the bottom right!
Now that we know that, first off, A has to be equal to 180-96 due to them being Supplementary Angles.
Therefore, A is 84 degrees.
Now to find x, we can use Supplementary Angles again.
x has to be 180-84 which is 96 degrees proving the theorum.

Answers
Answer:
The area of the red carpet is 1057 ft²
Step-by-step explanation:
The area of the red carpet is 112.35 ft².
Given that, the width of the stage =63 ft and the length of the stage =10 2/3 ft.
What is the area of a rectangle?The area of a rectangle is obtained by multiplying its length and width. Thus, the formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product "l × w".
Now, the width of the red carpet is 1/6 of the width of the floor = (1/6) × 63
=10.5 ft
Here, 10 2/3 can be written as 10.66 ≈ 10.7 ft
The area of the red carpet = length × width = 10.7 × 10.5
=112.35 ft²
Therefore, the area of the red carpet is 112.35 ft².

A long distance telephone company offer two plans . The deluxe plan cost $30 a month and offers unlimited long distance calling. The economy plan only costs $10 a month, but charges 5 cents per minute for every long- distance call. How many minutes a month can you use for long distance calls and still have money using the economy plan?
Answers
Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
