Answer:
C)265
Step-by-step explanation:
To find the median you list all the numbers in order from least to greatest. The number in the middle is the median.
In this case there are two middle number so you have to add them together then devide them by 2.
700, 740, <u>810, 900</u>, 1050, 1120.
810 + 900 = 1,710
1,710/2 = 855.
Your median is 855.
To find the difference you just subtract the two numbers.
1,120-855= 265.
<span>The volume of a rectangular prism = its base area * height
substitute:
</span>
x3 – 3x2 + 5x – 3 =<span> (x2 – 2) * h
h=</span> (x3 – 3x2 + 5x – 3)/<span>(x2 – 2)
so you can use the long division</span>
There would be 2.5 pizzas left since you cannot split the number 5 into a complete whole number. So 2 and a half would be the answer.
Answer: (20.86, 22.52)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-

, where
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
By considering the given question , we have


n= 58
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, 95% confidence interval for the amount of time spent on administrative issues will be :





Hence, the 95% confidence interval for the amount of time spent on administrative issues = (20.86, 22.52)
The volume of the case =
length x width x height
12cm x 6.5cm x 1.25cm =97.5cm^3
