Find the slope of the line that contains the points named.
K(c + d, c-d), L(c-d, c+ d)
A.0
B.-1
C 1
Answer:
B. - 1Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
K(c + d, c-d) ⇒ x₁ = c + d, y₁ = c - d
L(c-d, c+ d) ⇒ x₂ = c - d, y₂ = c + d
So, the slope:
[tex]m=\dfrac{c+d-(c-d)}{c-d-(c+d)}=\dfrac{c+d-c+d}{c-d-c-d}=\dfrac{2d}{-2d}=-1[/tex]

Mr. Mastrogiacomo is testing the hypothesis that the proportion of households in a large town that have high-speed internet service is equal to 0.7 against the alternative that the proportion is different from 0.7. What is the chief advantage of using a confidence interval to test this hypothesis rather than a significance test
Step-by-step explanation:
You can use a confidence interval (CI) for hypothesis testing. In the typical case, if the CI for an effect does not span 0 then you can reject the null hypothesis. But a CI can be used for more, whereas reporting whether it has been passed is the limit of the usefulness of a test.
John has 8 different flags that he wants to hang on the wall. How many different ways can the flags be arranged in a row?
Answer:
40,320 different ways
Step-by-step explanation:
Here, we want to arrange 8 flags in a row
In the row, there will be 8 places
The first place has 8 flags to be chosen from
The second place has 7 and like that
So mathematically, the number of ways that we can arrange the flags is 8 factorial ways
We have this as:
8! = 40,320 different ways

a swimming pool is 8 m long 8 m wide 8 m deep the water resistant paint needed for the pool cost $6 per meter what is the surface area of the pool that needs to be painted
Answer:
Two walls are 6*2
Multiply, add the products, round UP and multiply times 6.
NOTE: Why round up? because if you need, for example, 1.22 gallons, you have to get 2 gallons. If you buy just 1 you'll be short, and you can't buy 0.22 of a gallon.
Finish solving the equation -13y + 33 = 7.
Answer:
y = 2
Step-by-step explanation:
-13y + 33 = 7
add -13y to each side of the equation:
33 = 13y + 7
subtract 7 from each side:
13y = 26
divide both sides by 13:
y = 2

You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees
Answer:
B) 70 degrees
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees
We are given 2 angles in the triangle = 70° and 40°
The measure of the third angle is
180° = 70° + 40° + 3rd Angle
3rd Angle = 180° - ( 70° + 40°)
= 180° - 110°
= 70°
The measure of the other angle is 70°
Option B is the correct option.

Find the slope of the line that passes through the following points: `\left(\frac{2}{5},\frac{2}{3}\right)\ \ \left(-\frac{4}{9},\frac{3}{5}\right)` Show the work/explain!
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50

Find the measure of the indicated angle to the nearest degree
Answer:
A) 18°
Step-by-step explanation:
To find the measure of the indicated angle, we can use trigonometric ratios.
Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:
[tex]tan(?)=\frac{opposite}{adjacent}[/tex]
From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:
[tex]tan(?)=\frac{3}{9}[/tex]
Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:
[tex]?=tan^{-1}(\frac{3}{9})[/tex]
And we get:
? ≈ 18.4349488° ≈ 18°
So the answer would be 18°, or A.
I hope you find my answer to be helpful. Happy studying.

A circular pizza has a diameter of 16 inches. Each slice of pizza has a central of angle 45°. What is the area of each slice of pizza?
A. 3.1 in²
B. 6.13 in²
C.25.1 in²
D. 100.5 in²
I know that the area is 8π² I just don't know which answer choice it is.
Answer:
C.
Step-by-step explanation:
Radius = 16 ÷ 2 = 8
[tex]\frac{45}{360} *8^2*\pi =25.1[/tex] (3sf)
You can first find the total area of the circle which is [tex]64\pi[/tex].
Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)
For example, a semicircle's are would be [tex]\frac{180}{360} *8*\pi[/tex].
Answer:
C. 25.1 in²
