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:
<h2>2.6</h2>
Step-by-step explanation:
To solve this, we need to use the Pythagorean theorem to solve this.
The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.
3.4² + b² = 6.5²
11.56 + b² = 42.25
42.25 - 11.56 = b²
b = √30.69
b = 5.53985559 or about 5.5
4.9² + b² = 5.5²
24.01 + b² = 30.69
30.69 - 24.01 = 6.68
b = √6.68
b = 2.58456959666 or about 2.6
<h2>EDIT: the other user is incorrect, here's why</h2>
3.4 + 4.5 = 7.9
6.5² + 4.9² = 7.9²
66.26 doesn't equal 62.41
