Answer:
D. 6
Step-by-step explanation:
Here we are given that a sample of 256 was taken from a population with a standard deviation of 96 centimeters i.e. 
= 96 and n = 256.
And we have to calculate the margin of error for a 68% confidence interval.
Firstly from z score% table we observe that at 32% level of significance the z score critical value is given by 0.99744 .
<em>And Margin of error formula is given by ;</em>
* 
= 0.99744 * 
= 5.98
Approximately, we get Margin of error = 6.
Answer: The value of x is 1
Step-by-step explanation:
10x + 5 = 15
Collect the like terms which in this case are the whole numbers "5" and "15")
10x = 15 - 5
10x = 10
Divide both sides by 10
10x/10 = 10/10
x = 1
Thus, the value of x is 1
