Answer:
(B) The raw data can be retrieved from the dot plot, but not the histogram.
(C) Dot plots show the frequency of individual data values.
Step-by-step explanation:
There are two correct answers:
(B) The raw data can be retrieved from the dot plot, but not the histogram.
(C) Dot plots show the frequency of individual data values.
Dot plots are used for small data sets where values fall into a number of categories, unlike histograms.
Hack
for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
Answer:
Right
Step-by-step explanation:
For a contrapositive, we switch the hypothesis and conclusion and then negate it.
Switch
If it is a tree, then it is an elm
Negate
If it is not a tree, then it is not an elm.
Not tree belongs inside not elm

If the box if cubed for volume then lbh is 25x25x100=62500 cm ^3...if that's right. hope it helps any.
Answer:
m∠BCD = 120°
Step-by-step explanation:
Since the interior angles of a quadrilateral add up to 360°, then we get:
2x+x+2x+x=360°
6x=360°
<em>Divide both sides by 6</em>
x=60°
Since ∠BCD's value is 2x and x is equal to 60°, then ∠BCD is 120°.
