Answer:
The median is located at the 2.5th position, which is halfway between the values 52 and 57.
Step-by-step explanation:
The Median is referred to as the Middle term of a set of Data when ordered in Ascending/Descending order.
Consider the numbers 50, 230, 52, and 57
Arranging them in an Ascending Order
50, 52, 57, 230
The number of data in the set is even.
Dividing the data into two halves (50, 52 and 57, 230)
The median is halfway between the two halves.
The median is located at the 2.5th position, which is halfway between the values 52 and 57.

Answer:
640 = .8j
640 = 1.15c
Step-by-step explanation:
Let j = cost of Jocelyn's computer
c = cost of Corbin's computer
We know that Adrian's computer costs $640.
Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j
Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c
B. The number in both places is 7. It’s 700 x 10 = 7000
Let
x------> hours worked by Sara last week
y------> hours worked by Joan last week
z------> hours worked by Erin last week
we know that
x=28 hours ------> equation 1
y=x-6-----> equation 2
substitute the value of x in equation 2
y=28-6=22 hours
z=y/2------> equation 3
substitute the value of y in the equation 3
z=22/2=11 hours
<u>the answer is</u>
Sara worked 28 hours last week
Joan worked 22 hours last week
Erin worked 11 hours last week
