The general equation for the combination is as shown below,
C(n,r) = n!/(r!(n-r)!)
Note that the symbol "!" means factorial.
In our example, n = 5 and r = 0. Substituting the known values,
C(5,0) = 5!/(0!(5-0)!) = 1
The answer to this item is 1.
Population of moose in the national park = 240
percentage increase in the population of moose in the national park after a year = 25%
Then
Amount of increase in the population
Of moose in the national park in a year = (25/100) * 240
= 240/4
= 60
So
The number of moose present after 1 year
in the national park = 240 + 60
= 300
So from the above deduction we can easily conclude that the number of moose in the national park after a year is 300.
Answer: 28
Step-by-step explanation: 3(28)- 21=63
Answer:
18
Step-by-step explanation:
The question is asking you to evaluate -4.5b, which is a simplified way of saying
-4.5 * b
Since we know that b = -4, we can insert that instead of b.
-4.5 * -4
The two negatives cancel each other out, so you're left with
4.5 * 4 = 18
Answer:
7 rides
Step-by-step explanation:
So you start off with $21.50. Subtract $4 from 21.50 and you'll end up with $17.50. Now divide $17.50 with the price of each ride which is $2.50 and you end up with 7. You are able to go on 7 rides.
