Answer:

EASY PEASY!

Step-by-step explanation:

So First, We have to create an equation that can find the area!

Using the area of a trap. formula:

$A=((b_(1)+b_(2) ) )/(2) \left * h\n$

$A=(16+20)/(2) *24\nA=18*24\nA=432$

The area of the trapezoid is 432 ft^2

There you go!

Question 1 (4 points)Data Set:
8.2, 9.3, 8.5, 8.8, 9.0
What is the mean, median and mode? Make sure to label each answer. Round any
decimals to the tenths place.
Would mean, median or mode be the best measure to describe the data?

Answers

Answer:Mean = 8.7

Median= 8.8

Mode=Nil

Yes, they are the best measure to describe the data.

Step-by-step explanation:

Mean, otherwise known as average= total sum of data set/ number of data set

=45.8/5= 8.76

Median- the mid point data in a given set. We rearranged the data set in an ascending order to get the best measure. Median is 8.8

Mode- the most reoccurring number in a given data. For this data set, however, mode is not applicable as all each data value appears once
