At a small liberal arts college, students can register for one to six courses. Let be the number of courses taken in the fall by

Maslowich

According to the probability distribution, there is a 0% probability that a randomly selected student earns more than 18 credits.

A student earns 3 credits <u>per course</u>.

Thus, the probability distribution for the <u>number of credits earned</u> is:

$P(X = 3) = 0.06$

$P(X = 6) = 0.06$

$P(X = 9) = 0.12$

$P(X = 12) = 0.2$

$P(X = 15) = 0.41$

$P(X = 18) = 0.15$

Since no person takes more than 6 courses, there is a 0% probability that a randomly selected student earns more than 18 credits.

Use the number line below, where RS = 7y + 2, ST = 2y +6, and RT = 13y - 12

Hitman42 [59]

Answer: a. y=5

b. RS = 37 , ST =16 and RT = 53 .

Step-by-step explanation:

Given: On number line we have,

RS = 7y + 2, ST = 2y +6, and RT = 13y - 12.

a. Since its on number line so we have

RT = RS+ ST

i.e. 13y - 12 = (7y + 2) + ( 2y +6)

⇒ 13y - 12 = 7y + 2 + 2y +6

⇒ 13y-12 = 9y+8

⇒ 13y-9y = 8+ 12 [Subtract 9y from both sides and add 12 in both sides]

⇒ 4y = 20

⇒ y= 5 [Divide both sides by 4 ]

b. Now , RS = 7(5) + 2 = 35+2= 37,

ST = 2y +6 = 2 (5)+6 = 10+6 =16,

and RT = 13y - 12 = 13 (5)-12 = 65-12 = 53.

Hence, RS = 37 , ST =16 and RT = 53 .

A triangle has three angles that measure 15 degrees, 85 degrees and (4x - 20). What is the value of x?

Lostsunrise [7]

180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25
