Answer:
√3
Step-by-step explanation:
2√27 + √12 − 3√3 − 2√12
2√27 − √12 − 3√3
2√(9×3) − √(4×3) − 3√3
2×3√3 − 2√3 − 3√3
6√3 − 2√3 − 3√3
√3
Answer:
5c^4( 9c^2 + 4).
Step-by-step explanation:
The GCF of 45 and 20 is 5 and the GCF of c^6 and c^4 = c^4.
So the GCF is 5c^4 and the factors are:
5c^4( 9c^2 + 4)
Answer:
I and II.
Step-by-step explanation:
Dot plots are charts that<em> represent data points on a simple scale using filled circles</em>. Stemplots allow <em>plotting data by dividing it into stems (largest digit) and leaves (smallest digits)</em>. Both dot plots and stemplots are like histograms since they allow to compare data relating to only one variable, and are used for continuous, quantitive data, highlighting gaps, clusters, and outliers.
Histograms <em>use bars to represents amounts, with no space between the bars and </em>the height of the bars is proportional to the frequency or relative frequency of the represented amount. <u>We refer to the relative frequency of a case when this frequency is divided by the sum of all frequencies of the cases</u>. The proportionality between the height of the bar and the frequency is right when the width (interval) of the bar is the same for everyone, on the contrary, the area of the bar would be proportional to the frequency of cases.
Therefore, of all the above, the correct statements are I and II. Statement III is incorrect because relative <em>heights </em>are proportional to relative <em>frequencies</em>.
I hope it helps you!

Tips with decimals....
Our decimal system gives us the flexibility to write numbers as large or
small as we like. The key to the decimal system is the decimal point. Anything
on the left of the decimal point represents a whole number, anything on the
right of the decimal represents less than one (similar to a fraction). Going
from left to right, the value of each place on the right of the decimal point is
1/10 the value of the place on the left. Good luck!
