The 128° angle and the top right exterior angle are corresponding angles, which means they have the same angle measurement. The top right exterior angle is also 128°.

The ? angle and the bottom right exterior angle are also corresponding angles, so they will have the same measurements.

To determine the ? angle, we know that a line is 180°. So if we add the 128° angle and the bottom right exterior angle, they will equal 180°.

When we determine the bottom right exterior angle, we know the ? angle will be identical because they are corresponding angles.

180° of a line - 128° angle= bottom right exterior angle
180-128= 52°

Bottom right exterior angle= 52°

Therefore the ? angle also equals 52°.

I wish the angles were labeled so it would be easier to explain. I hope this makes sense.

Hope this helps! :)

The angles have special names identifying their positions with respect to the parallel lines<span> and </span>transversal<span>. They are corresponding angles, alternate interior angles, or alternate exterior angles. An angles is congruent to its matched angle.

Answer:

c. we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.

Step-by-step explanation:

Given that veterinary researchers at a major university veterinary hospital calculated a 99% confidence interval for the average age of horses admitted for laminitis, a foot disease that leaves the horse severely lame, as 6.3 to 7.4 years.

i.e. if X is the age of horses admitted for laminitis then the sample mean i.e. x bar follows a distribution with 99% confidence interval as

(6.3,7.4)

The interpretation of 99% confidence interval is the for sample of large size drawn at random from population we can be 99% confident that the sample mean will fall within this interval.

So the correct option is

c. we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.

data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares th

Answer:

the mean in set B is equal to the mean in set A (option C)

Question:

The question is incomplete as the answer choices were not given.Let's consider the following question:

Data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets?

a) median for set A is equal to the median for set B

b) Range for set A is greater than range for set B

c) The mean in set B is equal to the mean in set A

Step by step explanation:

We can describe a data set using four ways:

Center, spread, shape and unusual features.

Let's consider the center and spread.

Center: This is the median of the distribution.

Spread: This is the variation of the data set. If the range is wide, the spread is larger and If the range is small, the spread is smaller.

Rearranging the data set:

A = {30, 32, 32, 33, 40, 44, 45, 50}

B = {28, 30, 34, 35, 42, 43, 46, 48}

From the data:

The median for set A = (33+40)/2 = 73/2= 36.5

The median for set B = (35+42)/2 = 77/2= 38.5

Range = highest value - lowest value

The data ranges from 30 to 50 (range = 20) for A

The data ranges from 28 to 48 (range = 20) for B

Mean for set A = (30+32+32+33+40+4445+50)/8 = 306/8 = 38.25

Mean for set B = (28+30+34+35+42+43+46+48)/8= 306/8 = 38.25

In both data set the mean is equal to 38.25.

Therefore the statement that best compares the two data sets is the mean in set B is equal to the mean in set A (C)

Can some one please help me

If we want to calculate the full prize we need to calculate how much the tax was:

420* 17 $\frac{1}{2}$ %=420* $\frac{175}{1000}$ =420* $\frac{7}{40}$ =21* $\frac{7}{2}$ =73.5

so this is how much the tax was.

and the full prize is the cost of the ring and the tax: 420+73.5=493.5

so that's how much the buyer will pay

Graph 12x=4y-28 algebra 2

notka56 [123]

Answer:

see below

Step-by-step explanation:

A graphing calculator does this very nicely.

___

If I were graphing by hand, I might divide by 4 and add 7 to get ...

y = 3x +7

Now, you know the slope is 3 and the y-intercept is 7. Another point can be found by going left 1 and down 3 from the y-intercept, or left 2 and down 6 as shown on the attached graph. The line can be drawn through those points.
