Answer:

To allow for easy segregation, analysis, detecting patterns and understanding of the data

Step-by-step explanation:

Classes are, in simple terms, grouping of data based on certain unique characteristics.

Frequencies in classes are the amount of times that said characteristic occurs in an amount of event

The reasons the number of classes is set to between 5 and 20 is to allow for easy segregation, analysis, detecting patterns and understanding of the data

What is the answer for this Problem?
geniusboy [140]

Answer:

Increasing on the interval(s) -2\leq x\leq -4

Decreasing on the interval(s) -1\leq y\leq 1

Step-by-step explanation:

Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.

The increasing interval of the graph is -3

The decreasing interval of the graph is 0.5

Since the values are in the middle of the interval, it automatically becomes the answer.

Are all rhombuses parallelograms?
ss7ja [257]

Answer:

Yes

Step-by-step explanation:

All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent. Diagonals of a rhombus always bisect each other at right angles.
