Using the Classic Rock data in the Math 108 group on StatCrunch, create a histogram with the

liberstina [14]

The product of the frequency and PlayCount gives the number of songs

played from the information in the histogram.

Correct responses (rounded to the nearest whole integer)

1. 2%

2. 27 PlayCount per song

3. 68%

<h3>How does one analyze an histogram?</h3>

1. The given data from the histogram is presented in a tabular form as follows;

$\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}f&899&224&126&96&71&52&39&41&44&23&14&12&3&4&3\\x&10&20&30&40&50&60&70&80&90&100&110&120&130&140&150\end{array}\right]$

The percentages of song that where played over 100 times is given as follows;

∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651

Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36

$Percentage \ of \ songs \ played \ over \ 100 \ times = \mathbf{\dfrac{36}{1,651} \times 100} \approx \underline{2 \%}$

2. Mean of a frequency distribution is given as follows;

$Mean = \mathbf{\dfrac{\sum f\times x}{\sum f}}$

Where;

x = The PlayCount

From MS Excel, we have;

∑f·x = 44410

Which gives;

$Mean = \dfrac{44410}{1651} \approx \underline{27}$

3. Number of songs played less than 20 times = 899 + 224 = 1,123

$\mathbf{Percentage} \ of \ songs \ played \ less \ than \ 20 \ times = \dfrac{1,123}{1,651} \times 100 \approx \underline{ 68 \%}$

Solve the equation x + 0.7 = 1 - 0.2x in two different ways.Then check your answer.Show your work!

expeople1 [14]

Simplifying
x + 0.7 = 1 + -0.2x

Reorder the terms:
0.7 + x = 1 + -0.2x

Solving
0.7 + x = 1 + -0.2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.2x' to each side of the equation.
0.7 + x + 0.2x = 1 + -0.2x + 0.2x

Combine like terms: x + 0.2x = 1.2x
0.7 + 1.2x = 1 + -0.2x + 0.2x

Combine like terms: -0.2x + 0.2x = 0.0
0.7 + 1.2x = 1 + 0.0
0.7 + 1.2x = 1

Add '-0.7' to each side of the equation.
0.7 + -0.7 + 1.2x = 1 + -0.7

Combine like terms: 0.7 + -0.7 = 0.0
0.0 + 1.2x = 1 + -0.7
1.2x = 1 + -0.7

Combine like terms: 1 + -0.7 = 0.3
1.2x = 0.3

Divide each side by '1.2'.
x = 0.25

Simplifying
x = 0.25

During a recent year, charitable contributions in the United States totaled $330 billion. The following graph shows to whom this

victus00 [196]

Answer:

$49,500,000,000 billion or $49.5 billion

Step-by-step explanation:

10% of 330,000,000,000 = 33,000,000,000

5% of 330,000,000,000 = 16,500,000,000

15% of 330,000,000,000 = 49,500,000,000
