A stem and leaf plot (histogram) shows the mode as the longest list of "leaves." It is the easiest to use for finding mode.
A box-and-whisker plot tells you nothing about relative frequencies.
A scatter plot or line graph would require careful re-interpretation to determine the mode. If the amount of data is large and there are many data values with about the same high frequency, these charts may be unhelpful, too.

Answer:
7.5
Step-by-step explanation:
the slope m is a measure of the rate of change
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )
m = 
= 
= 7.5 ← rate of change
Answer:
Choice A.......< B is 147 degrees
Step-by-step explanation:
The total sum of the interior angles of a pentagon is 540 degrees
...So let's count the angles that we already have:
<A is 90
<B is ?
<C is 105
<D is 108
<E is 90
Noticed that both angles A and E are 90 since they have that little square that represents a straight angle.
Let's find the value for <B
90+ x + 105 + 108 + 90= 540
393 + x= 540
x= 540 -393
x = 147
So angle B is 147 degrees
One way in which to approach this proof would be to convert
1 (cos x)^2
------------- into ---------------- . Next, note that 1 - (sin x)^2 = (cos x)^2
(tan x)^2 (sin x)^2 and that 1 - (cos x)^2 = (sin x)^2.
Then we have:
(cos x)^2 (cos x)^2
------------- = -------------------- which is a true equation
(sin x)^2 (sin x)^2
