Complete Question:
Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough so that the sample proportions follow a normal distribution?
a) n=600 p=0.2
b) n=20, p=0.4
if np=10 and npq=10 then the data follows normal distribution
a) np= 120,
q= 1-0.2= 0.8
npq= 600 ×0.2×0.4 = 48
Normal distribution is appropriate and sample size is large enough
b) np= 8
q= 1-0.4= 0.6
npq= 20 × 0.4×0.6= 4.8
sample size is not large enough so normal distribution is not appropriate.
Round each coin weight to the nearest gram first, penny 3g, nickel 5g, dime 2g, quarter 6g, half dollar 11g. Now add those numbers together as he has one of each coin 3+5+2+6+11=27 grams
Independent variable on x-axis (value you can choose)
dependent variable on y-axis (corresponding value for the value you have chosen)
You can the hours and the distance traveled is a function of those hours.
also, I'd go in increments of 5. More accurate than increments of 15. The answer is D! <span><span>

Value of x is x=32
Step-by-step explanation:
We need to find the value of x of the equation 
Solving the equation and finding value of x

Adding 4 on both sides

Divide both sides by 0.5

So, value of x is x=32
