Answer:
For this case we know that the confidence level is 90% so then the significance level is 
and 
. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:
And the best option would be:
1.645
Step-by-step explanation:
We assume that the parameter of interest is 
and we can assume that the distribution for this parameter is normally distributed so then the confidence interval assuming a two sided interval is given by:
Where 
represent the estimator for the parameter, SE the standard error and 
the critical value.
For this case we know that the confidence level is 90% so then the significance level is and . And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:
And the best option would be:
1.645
It is 3 to 4
you find the GCF of 24 and 32 which is 8. then divide 24 and 32 by 8 to find the ratio
Answer:
A=d-c/b
Step-by-step explanation:
Answer:
Volume = 
cubic units.
Step-by-step explanation:
The volume of a rectangular prism is given by,
.......... (1) and
.......... (2)
Now, the length of the given prism is 
units, width is units and the height is units.
So. from equation (1) the volume, V = 
cubic units.
Now, base area = B = 
sq. units.
So, from equation (2) we get
cubic units. (Answer)
