Answer:
593,775 ways
Step-by-step explanation:
24 donuts have to be selected from 7 different varieties of donuts
n = 7
r= 24
Repetition is allowed
C(n+r-1, r) = C(7 + 24 - 1 , 24)
= C(30,24)
Recall that C(n,r) = n! /(n-r)! r!
C(30,24) = 30!/(30 - 24)! 24!
= 30!/(6!24!)
= 593,775 ways
Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.
This means 5x + 8x = 13x and -7 - 55 = -62
The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.
Answer:
Elephant: 14%
Panda: 18%
Tiger: 29%
Bonobo: 39%
Step-by-step explanation:
Take the number of attendants that liked each exhibit and divide it by the total amount of attendants.
Elephant: 336/2400 = .14 = 14%
Panda: 432/2400 = .18 = 18%
Tiger: 696/2400 = .29 = 29%
Bonobo: 936/2400 = .39 = 39%
I can tell you the inequality but you have to think of a real world situation. x<6, x is greater than or equal to -1
I think the answer is C though i'm not entirely sure please tell me I'm right or I'm wrong
