-33 is a rational number. It is an integer with a definitive stopping point (by this I mean it is not a decimal number with endless repeating digits).
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 = ![np](https://tex.z-dn.net/?f=np)
Variance = ![npq](https://tex.z-dn.net/?f=npq)
Standard Deviation = ![\sqrt{npq}](https://tex.z-dn.net/?f=%5Csqrt%7Bnpq%7D)
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 = ![np=100*0.08=8](https://tex.z-dn.net/?f=np%3D100%2A0.08%3D8)
Variance = ![npq=100*0.08*0.92 = 7.36](https://tex.z-dn.net/?f=npq%3D100%2A0.08%2A0.92%20%3D%207.36)
Standard Deviation = ![\sqrt{npq}=\sqrt{7.36}=2.7129](https://tex.z-dn.net/?f=%5Csqrt%7Bnpq%7D%3D%5Csqrt%7B7.36%7D%3D2.7129)
Based on the information given, it should be noted that the correct option is C. 3x - 8.

Solving equations.</h3>
From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:
= (2 × x) - 8.
= 2x - 8
Also, Ricky has x dollars. Therefore, the amount that they have together will be:
= 2x - 8 + x
= 3x - 8
