The IQR is the difference between the upper quartile of a set of data and the lower quartile of the data.
It is a measure of the spread of the data.
Answer:
a. .15 b. 5.40
Step-by-step explanation:
Hi! The first thing you want to do is find the unit rate, which would be 9 divided by 60. This should be 15 cents per hour. Next, for the second part, you multiply by 36, which should be $5.40. Hope this helps!
Answer:
tan60=p/b
tan60=12/x
x=37.5
now taking sin
sin60=p/h
sin60=12/y
y=(-40) but as length can be negative so
y=40
Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)
