The number of songs enjoyed from Eminem by all Learn4Life students is normally distributed with a mean of 7.0 songs and a standard deviation of 1.5 songs.

1. What is the probability an individual student likes more than 10 songs from Eminem?

2. What is the probability an individual student likes less than 5.5 songs from Eminem?

P(X > 10) = 0.0228

P(X< 5.5) = 0.1587

Step-by-step explanation:

Given that:

Mean = 7.0

standard deviation = 1.5

To find:

a) P(X>10)

Using the standard normal variation

Z =2.0

So;

P(X > 10) = P(Z > 2.0)

P(X > 10) = 1 - P(Z < 2.0)

From the tables

P(X > 10) = 1 - 0.9772

P(X > 10) = 0.0228

b) To find:

P(X < 5.5)

Z = -1.0

However;

P(X< 5.5) = P(Z < -1.0)

P(X< 5.5) = 0.1587

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
