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:
6
Step-by-step explanation:
The absolute value function always returns a positive value, that is
| a | = | - a | = a
Given
b(x) = | x + 4 | , then
b(- 10) = | - 10 + 4 | = | - 6 | = 6
Answer:
52°
Step-by-step explanation:
The angle 38° and m∠1 equal 90°, so 90-38=52.
Answer:
b is 7 units from 0.
Step-by-step explanation:
= 7 means that the absolute value of b is 7. This means that b can be -7 or 7, so it will always be 7 units from 0.
Hope this helps!
