Answer:
1). Mean: 14.2
Median: 13.5
Step-by-step explanation:
To calculate the mean, sum all values and divide by the number of values:
(13+16+14+17+13+12) / 6 ≈ 14.2
To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:
12,13,<u>13,14</u>,16,17
The median is (13+14)/2 = 13.5.
Using this explanation you should be able to find the rest.
Answer: 13 1/3
Step 1: Find the LCD
Step 2: Add the fractions
Step 3: Simplify
Answer:
-10-(-3)
Step-by-step explanations
we have-10-(-3). since law of basic operation:
+*+=+
-*-=+
so we have-10(-*-=+)
so we have-10+3
The formula of a distance between two points:
We have two points A(-5, 2) and B(-5, 8). Substitute:
d is a diameter of a circle because d = 2r = 2(3).
The center of a circle is in midpoint of AB.
The formula of a midpoint:
Substitute:
Answer: (-5, 5).
