Answer: the standard deviation is 2.4
Step-by-step explanation:
The formula for standard deviation is expressed as
s = √npq
Where
p = probability of success
q = probability of failure
n = number of samples
From the information given,
The probability of success, p is given as 0.2. It means that the probability of failure, q will be 1 - p = 1 - 0.2 = 0.8
There were 35 attempts. This means that total number of samples, n is 35
The standard deviation becomes
√35×0.2×0.8 = √5.6 = 2.366
Approximately 2.4
Answer: 77.84
Step-by-step explanation: you subtract 235.68 and 157.84 and that is you answer,
Answer:
A
Step-by-step explanation:
Answer:
x-2y/x
Step-by-step explanation:
x²-4xy+4y²/x²+xy-6y²÷x²+3xy/x²+6xy+9y² = x-2y/x
Answer:
#1.) x = 7
Step-by-step explanation:
#1.) Here, AB = BC because they are tangents that meet at a common endpoint
so 5x + 11 = 3x + 25
2x = 14
x = 7
