SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!

Answer:

$y^2 + 8y + 16$

Step-by-step explanation:

$(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =$

The first set of parentheses is unnecessary, so it can just be removed.

$= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)$

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

$= 6y^2 + 2y + 5 - 5y^2 + 6y + 11$

Now you combine like terms.

$= 6y^2 - 5y^2 + 2y + 6y + 5 + 11$

$= y^2 + 8y + 16$

The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of 0.5 min

Hitman42 [59]

Given:
μ = 2 min, population mean
σ = 0.5 min, population standard deviation

We want to find P(x>3).

Calculate the z-score
z= (x-μ)/σ = (3-2)/0.5 = 2

From standard tables, obtain
P(x ≤ 3) = P(z ≤ 2) = 0.9772
Therefore
P(x > 3) = P(z > 2) = 1 - 0.9772 = 0.0228

Answer: 0.02275
