Write the equation of the following line in slope-intercept form.
Answer:
y = [tex]\frac{2}{5}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m = [tex]\frac{4-2}{0-(-5)}[/tex] = [tex]\frac{2}{0+5}[/tex] = [tex]\frac{2}{5}[/tex]
The line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = [tex]\frac{2}{5}[/tex] x + 4 ← equation of line

Using the Classic Rock data in the Math 108 group on StatCrunch, create a histogram with the
variable PlayCount. When creating the histogram, check the box that says Value above bar and also check the Mean box. Answer the
following questions about the histogram. Recall that
there are 1651 songs played.
1. What percent of songs were played over 100 times?
1% (round to the nearest whole integer)
2. What is the mean?
songs (round to the nearest whole integer)
3. What percent of songs were played less than 20 times?
% (round to the nearest whole integer)
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%
How does one analyze an histogram?1. The given data from the histogram is presented in a tabular form as follows;
[tex]\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][/tex]
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
[tex]Percentage \ of \ songs \ played \ over \ 100 \ times = \mathbf{\dfrac{36}{1,651} \times 100} \approx \underline{2 \%}[/tex]2. Mean of a frequency distribution is given as follows;
[tex]Mean = \mathbf{\dfrac{\sum f\times x}{\sum f}}[/tex]
Where;
x = The PlayCount
From MS Excel, we have;
∑f·x = 44410
Which gives;
[tex]Mean = \dfrac{44410}{1651} \approx \underline{27}[/tex]3. Number of songs played less than 20 times = 899 + 224 = 1,123
[tex]\mathbf{Percentage} \ of \ songs \ played \ less \ than \ 20 \ times = \dfrac{1,123}{1,651} \times 100 \approx \underline{ 68 \%}[/tex]Learn more about percentages and histograms here:

When a number is divided by -3, the result is 12 more than the number. What is the number?
Answer:
x = -9
Step-by-step explanation:
let the number = x
So x ÷ -3 = x + 12
Mulitply both sides by -3: x = -3x -36
Add 3x to both sides: 4x = -36
Divide both sides by 4: x = -9

What is Probability?This is the likelihood or chance that an event will occur.
Probability = Expected/Total
Given the following
Pr(rain) = 3/5Pr (lightening) = 2/5The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5
The probability of a sporting event being canceled due to rain or lightning = 6/25

y can either be 10 or -10 since 10²=100 and (-10)²=100.
M is the midpoint of PQ. PM = 5x+8. PQ = 76. Find the value of x.
Answer:
x = 6
Step-by-step explanation:
Since M is the midpoint of PQ
PM = MQ = 1/2 PQ
5x+8 = 1/2(76)
5x+8 = 38
5x = 38-8=30
x = 30/5 = 6
Answer:
x = 6Step-by-step explanation:
First, let's revise a few definitions.
Definition of midpoint: The point that is in the middle of a line.We know that:
M is the midpoint of PQPM = 5x + 8PQ = 762PM = PQWork:
2PM = PQ=> 2(5x + 8) = 76=> 10x + 16 = 76=> 10x = 76 - 16=> 10x = 60=> x = 6Hence, the value of x is 6 units.
