300 juniors at Central High School took the ACT last year. The scores were distributed normally with a mean of 24 and a standard
Usimov [2.4K]

Answer:

150 students

Step-by-step explanation:

According to statement we have the following information

number of juniors=n=300

mean score=24

standard deviation score=4

The number of students that score above 24 is determined by

Number of students score above 24=number of juniors* P(student score above 24)

P(student score above 24)=P(x>24)=P(x-mean/sd>24-24/4)=P(z>0)=0.5.

Students score above 24=np=300*0.5=150

Hence there are 150 students scored above 24.

A particle moves along a circular path with radius 3 centimeters. The particle has an angular velocity of 3π/4 radians per secon
Nina [5.8K]

After 5 s, the particle traverses a path subtended by an angle of

(3π/4 rad/s) (5 s) = 15π/4 rad

Now, 15π/4 rad = 15/8 * 2π rad, so the arc has a length equal to 15/8 of the circumference of the path:

15/8 * 2π * (3 cm) = 45π/4 cm ≈ 35.3 cm
