Find the gradients of lines A and B. NEED ASAP

8 and - 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (2.5, 14) ← 2 points on line A

= = = 8

Repeat with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (2, 0) ← 2 points on line B

= = = - 4

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
