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]

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
Answers
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.
You had $22 to on four raffle tickets . After buying them you had $6. How much did each raffle ticket cost?
Answers
Answer:
X=4
Each raffle ticket cost 4 dollars
Step-by-step explanation:
22-4x=6
solve
-4x=-16
Divide
x=4
Answer: 4 bucks
Step-by-step explanation: 22 bucks at first
You buy four tickets, then you have 6 bucks
If the amount spent is x, then 22 - 4x = 6, so -4x + 22 =6
22 minus 22 is 0, cancel it out — 6 minus 22 is -16
-4 divided by -4 is 0, now you only have x. -16/-4 = 4
X = 4, 4 bucks per raffle ticket

If their all equal, then it is proportional.
If it’s not equal, it isn’t proportional.
You would need to divide the numbers.
Let’s say that the top number in a table is 9 and the bottom number is 90.
You would divide 90/9 and get 10. If you divide the rest, and their all 10, then it is proportional.
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
Answers
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.
