Answer:
The result is units.
Step-by-step explanation:
The coordinates for A and B:
A = (-2, 0)
B = (2, 2)
-To find the distance between A and B, you need the distance formula:
Where the first coordinate is
and the second coordinate is
.
-Use the coordinates A and B for the equation:
-Then, you solve the equation:
So, therefore the distance is units.
Answer: 28
Step-by-step explanation:
The mean of 15 numbers = 12
Then , the sum of the numbers = 12x15 = 180
Let the extra number included be , then
The new sum =
And the new total number will increase from 15 to 16
new mean = 13 , so we have :
therefore , the extra number is 28
