See the comment above.
Interchange the x and y in the original equation. call f(x) = y just for ease of understanding.
y = 3x + 5
Inverse
x = 3y + 5 Now solve for y.
(x - 5) = 3y Divide by 3
(x - 5)/3 = y

Remove the brackets.
x /3 - 5/3 = y

The answer is D <<<<< answer.

205 students enrolled in a freshman-level chemistry class. By the end of the semester, 4 times the number of students passed as

AlexFokin [52]

Answer: 164 students passed and 41 students failed.

Step-by-step explanation:

Let the number of students be x

x students failed, but 4 times the failed students passed.

So 4x students passed and x students failed.

4x + x = 205

5x = 205

x = 205/5

x = 41

41 times 4 is 164 and 41 times 1 is 41.

So 164 students passed and 41 students failed

scoundrel [369]

Answer:

-6.134 to +6.134

Step-by-step explanation:

given that a large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and a normal distribution

X is Normal with mean =6.1 and std dev = 1 unit

We are to determine the range of values containing 70% of the population of x

We know that normal distribution curve is bell shaped symmetrical about the mean.

So to find 70% range we can use 35% on either side of the mean

Using std normal distribution table the value of z for which probability from 0 to z is 0.35 is 1.034

Hence corresponding x value is

$x=6.1+1.034*1\\x=6.134$

i.e. 70% values lie between

-6.134 to +6.134
