Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2

if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode
it's a short 3 minute video :))
hope this helped!!
Answer: Betsy is incorrect.
Step-by-step explanation:
The area of a trapezoid is a+b/2 multiplied by h.
First, we should do 5+8/2= 6.5
Next, we multiply 6.5 with 4 because 4 is the height of the trapezoid.
6.5 times 4= 26
Betsy thought the answer was 52, but it is 26 so she is incorrect.\
I hope this helps, may god bless you! :)
Lengths are given to 1dp so the biggest that the lengths could be is 4.65cm and 5.35cm. if you use pythagoras on these to find hypotenuse, this is the upper bound.
Answer: x(0.55)
Step-by-step explanation:
Because 45% of the price is being taking, off we are still paying for 55% of the market price, because 100%-45%=55%.
55/100=0.55
So the sale price is x(0.55)
