Answer: 196
Step-by-step explanation:
As per given , we have
Population standard deviation: 
Significance level : 
Using the z-value table , the critical z value for 98% confidence : 
Margin of error : E= 01 lb
Sample size : 
Simplify , we get
Hence, the minimum sample size required for books = 196
Answer:
Step-by-step explanation:
Given
Required
Determine the average speed
Average speed is calculated as thus;
Convert Mixed Fraction to Improper fraction
Divide both sides of the fraction by 2
Hence:
The speed is:
Answer:x=-10.5
Step-by-step explanation:
Answer:
Are there any more numbers so we can sort them?
The growth factor that could be used to model the population will be 1.04. Then the correct option is D.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.
The population is increasing by 4% per year.
Then the growth factor that could be used to model the population will be
Growth factor = (1 + 4%)
Growth factor = (1 + 0.04)
Growth factor = 1.04
The growth factor that could be used to model the population will be 1.04.
Then the correct option is D.
