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:
30x+12
Step-by-step explanation:
distribute 6 into (2x+1) and 3 into (6x+2) basically multiply
12x+6+18x+6
combine like terms
12x+18x=30x
6+6=18
hope this helps
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i² = −1. The square of an imaginary number bi is −b². For example, 5i is an imaginary number, and its square is −25
