Answer:
B) 0.02
Step-by-step explanation:
<u>Use the Binomial Theorem</u>
We have the probability of success, 
, and the probability of failure, 
. The binomial coefficient, 
, represents the amount of possible combinations that 
items can be chosen out of 
items, with its respective formula 
.
Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02
So firstly, you want to foil - (7v^4 + 6) [Think of the minus sign as -1]: 
Next, combine like terms and your answer will be: 
Answer:
Step-by-step explanation:
The sum of the two costs is $52, so we can write ...
x + y = 52
The shoes cost $4 more than the jacket, so we can write ...
x - y = 4
These are your system of equations.
__
Subtract the second equation from the first:
(x +y) -(x -y) = (52) -(4)
2y = 48 . . . . . simplify
y = 24 . . . . . . .divide by 2
The cost of the jacket is $24.
Answer:
1131 students, is the best prediction.
Step-by-step explanation:
1450 divided by 50 = 29
50 - 14 = 36
36 x 29 = 1131
