Answer:
Median is 12
Step-by-step explanation:
9, 10, 4, 12, 15, 17, 18, 10, 12, 13
Sort the data
4, 9, 10, 10, 12, 12, 13, 15, 17, 18
Median position: (n+1)/2
(10+1)/2 = 5.5th value
Median:
(12+12)/2
24/2
12
Putting the numbers from smallest to largest
4,9, 10, 10, 12 12, 13, 15, 17, 18,
The median is the middle number
There are 10 numbers
The middle number is between the 12's, so it is 12
2
-2 -2/ -3+1 = -4/-2 = 2
you just have to use the slope formula
It's D.
B and C are correct
17/4 = 4.25
4 and 1/4 = 17/4
C) 26
Simplify using the FOIL method--used to multiply binomials--and then combine real and imaginary parts of the problem.
5 × 5 = 25 + positive 1(i) = 26
