Answer:
Mean = 8
Variance = 7.36
Standard Deviation = 2.7129
Step-by-step explanation:
This is a binomial distribution with parameters, n and p.
Where
n is sample size (given as 100)
p is the probability of success, or probability of defective (given as 8% or 0.08)
The mean, variance, standard deviation formula for binomial distribution is shown below:
Mean =
Variance =
Standard Deviation =
Where q would be probability of failure, or "1 - p"
Thus,
n = 100
p = 0.08
q = 1 - 0.08 = 0.92
SO, we have:
Mean =
Variance =
Standard Deviation =
Answer:
6
Step 1: Solve Square Root
Vx+3=x-3
x+3=(x-3)^2 (squared both sides)
x+3=x^2-6x+9
x+3-(x^2-6x+9)=0
(-x+1)(x-6)=0 (factor left side of equation)
-x+1=0 or x-6=0
x=1 or x=6
When you plug it in to check
1 (Doesn't Work)
6 (Work)
Therefore, 6 is your solution.
You should expect
5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's
1/9 45 times, or 1/9(45).
1*45 is 45
9*1 is 9.
45/9 is
5.

Answer: The required fourth term of the geometric sequence is
Step-by-step explanation: We are given to find the value of the fourth term in a geometric sequence with first term and common ratio as follows :
We know that
the n-th term of a geometric sequence with first term a1 and common ratio r given by
Therefore, the fourth term of the given geometric sequence will be
Thus, the required fourth term of the geometric sequence is
