To find the median of a data set order all the numbers from least to greatest, then find the number in the middle. If there are two numbers in the middle find the mean of the two numbers.
90 52 78 64 67 88 68 75 75 78 ← given
52 64 67 68 75 75 78 78 88 90 ← ordered l to g
75 and 75 are the two numbers in the middle, and since they are the same that means 75 is our median.
D) 75 is your answer.
This one is a bit confusing without a diagram anyway. We'll assume the typical labeling where A and B are consecutive angles, so the transverse line AB through the parallels makes A and B supplementary:
A + B = 180 degrees
12x + 46 + 7x + 1 = 180
19x = 180 - 47 = 133
x = 133/19 - 7
Answer:
4. 225
Step-by-step explanation:
The distance between points (-5, -3) and (-5, 12) is the length of the side of the square. Since both points have an x-coordinate of -3, they lie on the same vertical line. The distance between them is |12 - (-3)| = |12 + 3| = |15| = 15. The side measures 15 units.
area = side^2
area = 15^2 = 225
If you divide 120 by 150 you will end up getting 0.8 also known as 80%.
