b)5.05

c)0.02

Step-by-step explanation:

a)

P(Y>5)=?

This part is solved in the given picture.

b)

The mean of a uniform distribution is (a+b)/2.

Where a=4.95 , b=5.15.

E(Y)=(4.95+5.15)/2

E(Y)=10.1/2

E(Y)=5.05.

c)

The variance of a uniform distribution is (b-a)²/2.

V(Y)=(5.15-4.95)²/2

V(Y)=0.2²/2

V(Y)=0.04/2

V(Y)=0.02.

Can anybody find the measure of arc KL and arc JK?
lapo4ka [179]

Answer:

Arc KL = 30°

Arc JK = 90°

Step-by-step explanation:

Arc KL is a connected to a central angle with the measurement of 30°. Because it is a central angle, the arc's measurement will be the same as the central angle's measurement:

Arc KL = 30°

Arc JK is connected to a central angle that has a right angle measurement sign. A right angle = 90°. Because it is a central angle, the arc's measurement will be the same as the central angle's measurement:

Arc JK = 90°
