Answer:

n = 5

Step-by-step explanation:

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-8)) / (n - 2)

3 = ( 1 + 8 ) / ( n - 2)

3 = 9 / ( n - 2)

n - 2 = 9 / 3

n - 2 = 3

n = 3 + 2

n = 5

Find the slope of the line that passes through the pair of points.<br><br> (–5.5, 6.1), (–2.5, 3.1)

hjlf

Slope of the line is -1.

Step-by-step explanation:

Given points are,

(-5.5,6.1),(-2.5,3.1)

Here,

$x_{1} = -5.5 ,\ \ \ x_{2}=-2.5\\y_{1} = 6.1,\ \ \ y_{2}=3.1$

Slope = m = $\frac{y_{2}-y_{1}}{x_{2}-x{1}}$

Putting values;

$m=\frac{3.1-6.1}{-2.5-(-5.5)}\\m=\frac{-3}{-2.5+5.5}\\m=\frac{-3}{3}\\m=-1$

Slope of the line is -1.

P’(rolling a number less than five and landing on tails)

Ksenya-84 [330]

Answer:

P’(rolling a number less than five and landing on tails) = 1/3

Step-by-step explanation:

dice has 6 numbers and you only want 4 of them, so you have a 4 in 6 chance of doing that which is equal to 4/6 or 2/3

a coin has 2 side so the chance of getting tails is 1 in to or 1/2

therefore the probability of getting a number less than 5 and a tails is

4/6 times 1/2 = 4/6 x 1/2 = 4/12 = 1/3

or you can do it this way:

2/3 times 1/2 = 2/3 x 1/2 = 2/6 = 1/3
