Answer:

Choice C

Step-by-step explanation:

A and B represent symmetric distributions, that is most data values lie in the middle and the both tails are equally longer.

C represents a positively skewed distribution, most of the data values lie to the left with a few points skewing the shape of the distribution to the right.

Answer:

Option C is the answer.

Step-by-step explanation:

We will try to understand the behavior of each graph given in options.

A). In this graph bars show the symmetry on both the sides of the highest bar. Therefore, the graph represents a symmetric graph.

B). In this graph most of the points have been plotted on the left side of the maximum data value and has a long tale on the left side. Therefore the graph is negatively skewed graph.

C). In this graph most of the points have been plotted on the right side of the maximum valued data. Hence it has a tale on the right side. Therefore, The given graph is positively skewed.

D). This graph has the equal tails on each side of the maximum value. Therefore represents a symmetric graph.

Option C is the correct option.

Which expression is equivalent to...

olga_2 [115]

Answer:

$8m^5$

Step-by-step explanation:

Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)

This gives us the fraction: $\frac{24m^7}{3m^2}$

We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction: $\frac{24 * m * m * m * m * m * m * m}{3 * m * m}$

Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:

$\frac{24 * m * m * m * m * m}{3}$ which can be simplified in exponent form as: $\frac{24m^5}{3}$ , now all we have to do is divide the 24 by the 3, to get 8
