The mean is simply the average of the total movies seen so..
the median is the middle number (or the average of the middle 2 numbers)
so if we line up the numbers in order and cross them out from both ends we get 12 & 14 so we take the average of the 2
Answer:
The distance between parallel lines is
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Line A and Line B are parallel lines, because their slopes are equal
Step 1
Find the slope of the given lines
isolate the variable y in the equation A
The slope is
Step 2
Find the slope of the perpendicular line to the given lines
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so
we have
-----> given lines
substitute
Step 3
Find the equation of the perpendicular line that pass though the origin
with the slope and the point (0,0) Find the equation of the line
Step 4
Using a graphing tool
Graph the two parallel lines and the perpendicular line
The intersection points are
and
see the attached figure
we know that
the distance between the points A and B is the distance between parallel lines
the formula to calculate the distance between two points is equal to
substitute the values
Answer:radius =10 units
Step-by-step explanation:
Given
Equation of circle is given by
Now general equation of circle with center with radius is given by
Comparing and we get
Thus center is
and radius
A^2 + b^2 = c^2
132^2 + b^2 = 157^2
17424 + b^2 = 24,649
b^2 = 24,649 - 17424
b^2 = 7225
b = square root 7225
b = 85 <== the missing leg is 85 units
Lauras step is correct...she rearranged the formula making it :
b^2 = c^2 - a^2.....and subbed in numbers correctly. She just didn't finish
