Answer:

y = 3

Step-by-step explanation:

$10-2y+4+4y+20$

Combine like terms

$2y+14=20$

Move all terms not containing y to the right side of the equation.

$2y=6$

Divide both sides by 2

y = 3

Plz mark me brainliest!

It's ok if u don't...lol

Answer:

required probability is 0.8413

Step-by-step explanation: Given mean $\mu =15$ minutes, standard deviation $\sigma =4$ seconds, we need to find $P\left ( X\leq 19 \right )$ . Using z score

$z=\frac{X-\mu }{\sigma }\\=\frac{19-15}{4}\\=1$

So,

$P\left ( X\leq 19 \right )\\=P\left ( Z\leq 1 \right )\\=0.8413$

Passes through (3, 4) and (5, -4) how do I solve

Answer:

y = - 4x + 16

Step-by-step explanation:

Assuming you require the equation of the line passing through the points.

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 ) = (3, 4) and (x₂, y₂ ) = (5, - 4)

m = $\frac{-4-4}{5-3}$ = $\frac{-8}{2}$ = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 4), then

4 = - 12 + c ⇒ c = 4 + 12 = 16

y = - 4x + 16 ← equation of line
