Definition: A histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval.

According to the given histogram,

0-20 years occur 15 times,

21-40 years occur 40 times,

41-60 years occur 40 times,

61-80 years occur 15 times.

This shows that the data is symmetrical and the majority of the attendees were between the ages of 21 and 60 (40 times).

Answer: correct choice is B.

A college theater charges $5 handling fee. tickets cost $58. what would the slope be

schepotkina [342]

The slope would be 58.

Slope = (change in y) / (change in x)

That relationship is established by the fixed cost of each ticket ($58). The handling fee is a constant that would shift the curve upward by $5, but would have no effect on the slope of the line since it is completely independent from the number of tickets being purchased (x).

Simplify. 3√-28 A 2i√7 B 12i√7 C 61√7 D -6i√7

netineya [11]

Answer:

Step-by-step explanation:

We want to simplify the expression:

$\displaystyle 3 \sqrt{-28}$

Rewrite:

$\displaystyle = 3 \sqrt{ 4\cdot 7 \cdot -1}$

Rewrite:

$\displaystyle = 3 \cdot \sqrt{4} \cdot \sqrt{7} \cdot \sqrt{-1}$

Simplify. Let i = √(-1). Hence:

$\displaystyle = 3 \cdot \left(2\right) \cdot \left(i\right) \cdot \sqrt{7}$

Multiply:

$\displaystyle = 6i\sqrt{7}$

In conclusion, our answer is C.
