Answer:

y = - $\frac{3}{5}$ x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, - 4) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m = $\frac{-1+4}{0-5}$ = $\frac{3}{-5}$ = - $\frac{3}{5}$

Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = - $\frac{3}{5}$ x - 1 ← equation in slope- intercept form

lana [24]

Variance of a continuous random variable X is defined as

$\int\limits_D {(x-\mu)^2f(x)} \, dx$

Standard deviation is defined as

$\sigma = \sqrt{Var(X)}$

Hence standard deviation is the positive square root of variance.

Alik [6]

Answer:

b = -1

Step-by-step explanation:

Solve for b means, write in the form of b =...

Given

+ b = - 1 and this is the same as b = - 1.

That is because the plus sign has no real meaning here, so you can ignore it as if it was not there at all.

It so turns out you now have the answer!

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has th

vovikov84 [41]

Given that the manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.

Then, the ratio value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.

Given that the manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.

Then, the ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.

Given that the manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.

Then, the ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.
