What is the circumference of a circle with a diameter of 45 centimeters? A. 282.7 centimeters B. 70.7 centimeters C. 6,361.7 centimeters D. 141.4 centimeters
Answers
Circumference, C = πd d = diameter.
C = π*45
C = 45π
C ≈ 45*3.142
C≈ 141.39
C ≈ 141.4
Option D.
It is 141.4 centimetres. This is because the circumference is obtained by multiplying pi with the diameter.
The ratio of SAMs age to hank is 5 to 3. If the sum of their age is 24. How old is is hank?
Answers
lets consider SAM's age is 'x' and Hank's age is 'y' So as per given data Sam's age is 5/3 times of Hank's age so x = 5/3 * y 3x = 5y --> equation 1 and also sum of their ages is 24 so, x + y = 24 we need to find Hank's age (y) so x = 24 - y Now replace x value in equation 1 3(24-y) = 5y 72-3y = 5y 72 = 3y+5y 8y= 72 y= 72/8 y = 9 years.
So the Hank's age is 9 years

Is it possible for an event to have a probability of 1? Explain.
Answers
An event that is certain to happen has a probability of 1(So yes an event can have a probability of 1). An event that cannot possibly happen has a probability of zero. (examples below) --If it is Thursday, the probability that tomorrow is Friday is certain, therefore the probability is 1. --If you are sixteen, the probability of you turning seventeen on your next birthday is 1. It's a certain event.
