Answer:
A motor running at 75 revolutions per second.
Step-by-step explanation:
Given statement: A motor running at 4500 RPM, revolutions per minute.
⇒ In one minute , a motor running at 4500 revolutions.
Use conversion:
We have to calculate how many revolutions per second.
in 60 sec , a motor running at 4500 revolutions
then,
in 1 sec , a motor running at 
revolutions.
Therefore, a motor running at 75 RPS, revolution per second.
Answer:
times 3
Step-by-step explanation:
So this is like integers because it is negative numbers and positive numbers when it is positive and odd numbers that means you could use a number line because numberlines have positive and negative numbers.
Answer:
i
Step-by-step explanation:
Next time please share the possible answers. Thank you.
Notice that i^4 = 1.
Factoring i^21, we get (i^20)(i^1) = (1)^20i = i
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
