More data can be applied to the frequency distribution table. You can measure the "midpoint" (or "class mark") of each class as: Midpoint = Lower class limit + Upper class limit 2 . . The proportion of the data that falls in that class is the "relative frequency" of each class.
Answer:
$70.50
Step-by-step explanation:
8.50 x 8 = 68
68 + 75 = 143
143 - 72.50 = 70.50
Answer:
Step-by-step explanation:
5x + 2y = -3
3x + 3y = 9
15x + 6y = -9
-15x - 15y = -45
-9y = -54
y = 6
5x + 2(6) = -3
5x + 12 = -3
5x = -15
x = -3
(-3, 6)

Answer:
10.44
Step-by-step explanation:
First plot each of the points on to a graph at their respective positions.
Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)
You can then use the pythagorean theorem
.
Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation.
Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 =
which in turn is 109 = 
Then take the square root of 109 to remove the square from the c to get c = 10.44
