Answer:
The picture provided is the correct answer
Step-by-step explanation:
It needs to be greater than 4 or less than -4 in order for the absolute value to be greater than 7, so you're good.
SOLUTION
From the question, we want to find the probability of selecting a slip of paper with the letter t on it, then selecting the letter r, with replacement.
This means the probability of selecting t and r.
That is

There are 12 letters (total outcomes). And there are 2r and 2t.
So probability becomes

Hence the answer is
The 85th percentile is the cutoff time

such that

In other words, the 85th percentile refers to the time needed to belong to the top 15% of the distribution; more generally, the

percentile is the top

of the distribution.
Anyway, to find this value of

, transform

to a random variable

with the standard normal distribution using

where

is the mean of

and

is the standard deviation of

.

Here

is used to denote the z-score corresponding to the cutoff time

. Referring to a z-score table, you find that this occurs for

Answer:
The equations in the slope-intercept form
y = - 2 x + 5
y = - 2 x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
- m is the slope of the line.
To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.
Let us do that with the given equations
∵ 2x + y = 5
→ Subtract 2x from both sides to move x to the right sides
∴ 2x - 2x + y = 5 - 2x
∴ y = 5 - 2x
→ Switch 5 and - 2x
∴ y = - 2x + 5
∵ 3y = 9 - 6x
→ Divide each term by 3 to make the coefficient of y = 1
∴ 
∴ y = 3 - 2x
→ Switch 3 and - 2x
∴ y = - 2x + 3
The equations in the slope-intercept form
y = - 2x + 5
y = - 2x + 3
