The data is already sorted for us. The median of this set is the middle most value which is 7 (in slot 4; three values to the left and three values to the right).
So the median is originally 7
If we add 5 to each data value we get
3+5 = 8
4+5 = 9
6+5 = 11
7+5 = 12
9+5 = 14
9+5 = 14
11+5 = 16
So the old data set
{3,4,6,7,9,9,11}
shifts to
{8,9,11,12,14,14,16}
after we add 5 to each value
The middle most value of the updated set is 12. It corresponds exactly to the old median of 7.
So we technically didn't even need to add 5 to all of the values to see what the new median would be. We simply need to add 5 to the old median to get the new median
I.e,
(new median) = (old median) + 5
Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8

Answer:
256, -256
Step-by-step explanation:
Absolute value simply removes the negative and does nothing to positive numbers
I think those were absolute value bars. not sure.
Jason has $2 worth of dimes and quarters. He has 13 more dimes than quarters. The Number of dimes = 15 and Number of quarters = 2.
<h3>What is a linear equation?</h3>
A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
The total money = $2 = 200 cents
Types of coins are dimes and quarters
Number of dimes are 13 more than quarters
let number of dimes be x and quarters be y
so our equation
