Answer:
a. 720
b. 0.3
Step-by-step explanation:
a.
Three balls are selected at random without replacement.
First ball can be selected in 10 ways
Second ball can be selected in 9 ways
Third ball can be selected in 8 ways
Thus, there are 10×9×8 =720 different ways of selecting three balls.
b.
There are three cases that satisfy this condition
- first ball picked is 5, the others are not
- first ball is not 5, second is 5, third is not
- first and second ball is not five, third ball is 5
Each probabilities are:
Thus, one of the balls selected is the number 5 is then
Answer:
56.52 feet.
Step-by-step explanation:
We have been given that a rotating sprinkler sprays at a steady stream of water that is nine feet long. We are asked to find the approximate circumference of a circular area it sprays with water.
We will use circumference of circle formula to solve our given problem.
, where r represents radius of the circle.
Therefore, the circumference of the circular area is approximately 56.52 feet.
Answer:
No
Step-by-step explanation:
Counterexample for the numbers 25 and 10
The actual LCM is 50
If you were to multiply both numbers together you would get 250 which is incorrect
Zero.
The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.
