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:
22221
Step-by-step explanation:
I set up the problem like this
823
x27
Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!
Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!
I then added up the two values! (Sorry this probably sounds confusing!)
Answer:
the density of the iron is 7.9 g /cm^3
Step-by-step explanation:
The computation of the density of the iron is shown below:
Density = weight ÷ volume
= 474 ÷ (5 × 3 × 4)
= 474 ÷ 60
= 7.9 g /cm^3
Hence, the density of the iron is 7.9 g /cm^3
I think it’s -8x + 24
Could be wrong, but I hope it helps :)
Answer:
D
Step-by-step explanation:
5 + n is the sum of 5 and a number
amd then "less than or equal to -7" represents the no more than -7
