Number of Students
4

7

5

Would a dot plot or a histogram best represent the data presented here? Why?
A) Histogram, because a large number of scores are reported as ranges
B) Histogram, because a small number of scores are reported individually
C) Dot plot, because a large number of scores are reported as ranges
D) Dot plot, because a small number of scores are reported individually

Answers

Answer:

A

Step-by-step explanation:

histogram's report ranges

ex.

60 people in 20 - 29

20 people in 30 - 39

10 people in 40 - 49

A) Histogram is suitable for this data, as large number of scores are reported as ranges

Histogram is a form of graphical representation of data, presenting a group of data points in particular ranges.

Dot plot presents data simply by number of dots, on various data points.

In this case : students scores are not in individual numerical units, but in range. Scores : 20 to 29 ... 60 to 69

So, Histogram is suitable in this case, and not Dot Plot

Find the missing angle measurement.

A. 63 degrees
B. 73 degrees
C. 90 degrees
D. 153 degrees

Answers

To find the missing angle measurement, we will use the Angle Sum Property to create an algebraic equation that can solve for a missing angle given two angles in a right triangle.

Create an Equation

We are given an angle of 27º and 90º (refer to the square in the bottom right-hand corner.

We know that all of the angles in a triangle must add up to 180º using the Angle Sum Property.

Create an equation to find the missing value.

[tex]27 + 90 + x = 180[/tex]

Combine Like Terms

Combine the constants on the left side of the equation.

[tex]27 + 90 + x = 180[/tex]

[tex]117 + x = 180[/tex]

Subtract

Subtract 117 from both sides of the equation.

[tex]117 - 117 + x = 180 - 117[/tex]

[tex]\boxed{x = 63}[/tex]

The final answer is x = 63º.

Answer:

63 degrees
