1. Theta is a central angle in a circle of radius 4 inches. If theta measures 30 degrees, find the arc length s cut off by theta. 2. Theta is a central angle in a circle of radius 3 feet. If theta measures 240 degrees, find the area of the sector formed by theta.

Solve for both.

is this a multiple choice question?

if so it's a and c

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
