Answer:
6840
Step-by-step explanation:
multiply combinations
n!/(r!(n − r)!)
n choose r
n (objects) = |n
r (sample) = r
(4 teachers, CHOOSE 2)*(20 students, CHOOSE 3)
C(4,2) times C(20,3) =
C(n,r)=?
C(n,r) = C(4,2)
4! / (2!(4-2)!)
4! /2! x 2!
= 6
C(n,r)=?
C(n,r) = C(20,3)
20! / (3!(20-3)!)
20! / 3! x 17!
= 1140
6 * 1140 = 6840

Answer:
$20.30
Step-by-step explanation:
The usual price of the gift is $29.00
Marie will get 30% DISCOUNT on this price if she uses her coupon. So, the final price would be 30% less than $29.00
First, we need to find 30% of $29.00. Then we need to subtract that from original price (29).
Convert percentage to decimal first:
30% = 30/100 = 0.3
Now multiply this with 29 to get:
0.3 * 29 = $8.70
We subtract this from original price to get DISCOUNTED PRICE:
$29.00 - $8.70 = $20.30
Answer:
1/10
when you do the LCM you get 70
divide each fraction by 70 and you will get the least to be a tenth
Basically, the equator is like the x-axis of the world and the prime meridian is like the y-axis. You locate places by distances from these lines.
