Answer: x = 22
Step-by-step explanation:
We must isolate the x by itself.
We need to add 5 to both sides of the equation so it cancel out from the side with x.
So x = 22
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:
Median: 7.5
Mean: 8.6
Step-by-step explanation:
Median = the average of the 2 middle numbers of the set in ascending order, 6, 6, 6, <u>7, 8</u>, 10, 12, 14
(7+8)/2 = 2
Mean = the sum of the numbers divided by the number of values
6 + 6+ 6+ 7 +8 +10 +12 +14/8
69/8
8.625
Slope= 2.3
In the equation y=mx+b m=slope and b=y-intercept
