I think 80 I’m not sure ........
Answer:
Skewed right. btw thx have a nice day!!!!!!!!!!!!!!!
Step-by-step explanation:
Distance of Foci = c
Then,
c = 4
As c^2 + b^2 = a^2
And, b = 3
Then us will have:
a^2 = 4^2 + 3^2
a^2 = 16 + 9
a^2 = 25
a = 5
The equation of ellipse to this question is:
x^2 / a^2 + y^2/b^2 = 1
Then,
x^2 / 25 + y^2 / 9 = 1
Given:
2 yellow flags
3 green flags
5 red flags
for a total of 10 flags.
It is a permutation of 10 objects, not all distinct.
The number of permutation is:
10! 3,528,800
---------------- = -------------- = 2,520
2! * 3! * 5! 1,440
There are 2,520 different signals that can be made using the given flags.
