Answer:
15504 different groups
Step-by-step explanation:
We have a total of 20 people, and we want to know how many groups of 5 people we can make, where the order of the people inside the group doesn't matter, so we can solve this question calculating the combination of 20 choose 5.
The formula for combination is:
C(n, p) = n! / (p! * (n-p)!)
In this case, we have n = 20 and p = 5, so:
C(20, 5) = 20! / (5! * 15!) = 20*19*18*17*16 / (5*4*3*2) = 15504
So we have 15504 different groups.

Answer:
8
Step-by-step explanation:
2log(x)=log(64)
By logarithms properties
log(x²)=log(64)
When you have log or ln in both sites, you delete them and...
x²=64
![\sqrt[]{x^{2} } =\sqrt{64} \\x=8](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7Bx%5E%7B2%7D%20%7D%20%3D%5Csqrt%7B64%7D%20%5C%5Cx%3D8)
Answer:
A:
The perimeter of the parking lot is 302 yards.
The area of the parking lot is 5,544 yards squared.
B: Perimeter
C: Area
Step-by-step explanation:
A:
To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.
2(63) + 2 (88) = 302
To find the area, we multiply the length by the width. 63 × 88 = 5,544.
B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.
C: We would be paving the entire area of the parking lot.
