What happens to the mean of the data set {2, 4, 5, 6, 8, 2, 5, 6} if the number 7 is added to the data set?
Answers
Answer:
It increases
Step-by-step explanation:
The mean of the given data set of 8 values is 4.75 ([tex]\frac{2+4+5+6+8+2+5+6}{8}[/tex])
Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:[tex]\frac{2+4+5+6+8+2+5+6+7}{9}[/tex], which is equal to 5

Marcus and Lara each have the same number of songs on their ipods. Marcus has 10x + 8 songs and Lara has
15x - 92 songs. What is x?
Answers
Answer:
The value of x is 20.
Step-by-step explanation:
Given that
Number of songs Marcus has = 10x+8
Number of songs Lara has = 15x-92
It is also given that they have the same number of songs that means both the expressions should be equal.
Putting both equal
[tex]10x+8 = 15x-92[/tex]
This is a linear equation in one variable which can be solved using properties of equality
Subtracting 10 from both sides
[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]
Adding 92 on both sides
[tex]8+92 = 5x-92+92\\100 = 5x[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]
Hence,
The value of x is 20.

What is the equation of the line passing through the points (-4,3) and (2,7)?
Answers
Answer:
[tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]
Step-by-step explanation:
First, find the slope of the line:
The formula for finding the slope is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Plug in the points:
[tex]\frac{7 - 3}{2 - (-4)}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
So now the equation is y = [tex]\frac{2}{3}[/tex]x + b
Now solve for b by plugging in one of the points:
(2,7)
y = [tex]\frac{2}{3}[/tex]x + b
7 = [tex]\frac{2}{3}[/tex]2 + b
7 = [tex]\frac{4}{3}[/tex] + b
b = [tex]\frac{17}{3}[/tex]
So the equation will be [tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]

John takes out a loan for $ 12 , 000 at a simple interest rate of 4.5 % to be paid back in 36 monthly installments. What is the amount of the monthly payments?
Answers
Answer: $378.33
Step-by-step explanation:
First we calculate the Simple interest which will be:
= 12000 × 4.5% × 3
= $1620
Total amount to be paid = $12000 + $1620 = $13620
Since there are 36 monthly installments, the amount of the monthly payments would be:
= $13620 / 36
= $378.33

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-8,7) and (4,3)
Answers
If the gradient of the line segment is m, then the gradient of its perpendicular bisector is -1/m.
Gradient of line= (y2-y1)/(x2-x1) =
(3-7)/(4- -8) = (-4/12) = -1/3
Therefore the gradient of the perpendicular bisector is 3
The perpendicular bisector will pass through the midpoint of line segment.
Midpoint of line= ((x1+x2)/2 , (y1+y2)/2)
=( (-8+4)/2 , (7+3)/2) = (-2,5)
Equation of perpendicular bisector : y=mx + c.
We know m is 3
So we have:
y=3x+c
The bisector passes through (-2,5). Replace in equation to find c.
5 = 3(-2) + c
5 = -6 + c
c = 5+6 = 11
So equation if bisector is y = 3x + 11
