When would you choose to use a histogram to represent data?

Answers

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins. Bar charts, on the other hand, can be used for a great deal of other types of variables including ordinal and nominal data sets.

Answer:

178.7 ft.

Step-by-step explanation:

The kite is (x + 5) ft above the ground. So we need to find x first.

Use the trigonometric identity Sine.

[tex]Sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin44=\frac{x}{250} \\\\x=250*sin44\\x=250*0.69\\x=173.66\ ft\\[/tex]

Rounding your answer to the nearest tenth would be 173.7 ft.

Now the kite is above the ground x + 5 which means

173.7 + 5 = 178.7 ft.

11. Jimmy bought some used video games and used movies at the Movie Barn. He bought a total of 15 items and spent $106 in all, not including tax. Each used video game cost $10 and each used movie
cost $6. How many of each item did he buy?

Answers

Answer:

Used Video game = x = 11

Used movie = y = 4

Step-by-step explanation:

Let

Used Video game = x

Used movie = y

x + y = 15 (1)

10x + 6y = 106 (2)

From 1

x = 15 - y

Substitute x = 15 - y into (2)

10x + 6y = 106

10(15 - y) + 6y = 106

150 - 10y + 6y = 106

-10y + 6y = 106 - 150

- 4y = -44

Divide both sides by -4

y = -44/-4

= 11

y = 11

Substitute y = 11 into (1)

x + y = 15

x + 11 = 15

x = 15 - 11

= 4

x = 4

Used Video game = x = 11

Used movie = y = 4
