6. A music video website received 5.000
comments on a new song they released
The next day, the artist performed the song
on television and an additional 1500
comments were made on the website. What
was the percent of increase?
Answer:
30%
Step-by-step explanation:
To be able to calculate the percent of increase between two numbers, you have to divide the increase by the initial number and multiply by 100:
Increase= 1,500
Initial number=5,000
Percent of increase=(1,500/5,000)*100
Percent of increase=0.3*100
Percent of increase=30%
According to this, the answer is that the percent of increase was 30%.
Which of the following best represents a linear proportional relationship?
A linear proportional relationship is shown by y = 3x - 7.
What is a linear relationship?We know that when we talk about a linear relationship, we mean the kind of relationship that would obey the equation of the straight line and the equation of the straight line would be y = mx + c
We have to look at the representations and see the one that actually fits into the model that have been shown above and when we look at it we can see that the y = 3x - 7.
This follows the pattern of the equation of the straight line.

The best representation of a linear proportional relationship is the table of values
How to determine the best linear proportional relationship?From the question, we have the following parameters that can be used in our computation:
The list of options
As a general rule, the equation of a linear proportional relationship is represented as
y = kx
Where k is the constant of proportion
This means that the given equations are not proportional relationship because they do not have the form y = kx
i.e. y = 3x - 7 and y = 8x + 25 do not have the form y = kx
Also, the equation y = kx implies that the graph passes through the origin
So, the given graph is not
The equation of the table is represented as
y = Y/X * x
So, we have
y = 2/24 * x
This gives
y = x/12
The equation of the table is of the form y = kx
Hence, the solution is the table of values

The number of vehicles passing through a bank drive-up line during each 15-minute period was recorded. The results are shown below.

Find the median number of vehicles going through the line in a 15-minute period.
A: 27 vehicles B: 25.85 vehicles C: 30 vehicles D: 26 vehicles
Answer:
The correct answer is: Option D: 26 vehicles
Step-by-step explanation:
Median is the middle value of a sorted data set.
The formula for median depends on the number of values in the dataset.
First of all we have to arrange the given data in order
So,
14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34
Counting the values in the dataset
n = 20
As the number of values is even, the formula for median will be
[tex]M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)[/tex]
Putting the values
[tex]M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)[/tex]
The 10th value in dataset is 26 and 11th is also 26 so
[tex]M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26[/tex]
Hence,
The correct answer is: Option D: 26 vehicles

Davis has 15 quarters . Each quarter is 1 3/4 mm thick . If Davis stacked up all 15 quarters on top of each other , how tall would the stack be ?
Answer:
26 1/4
Step-by-step explanation:
1 3/4*15=26 1/4
If Davis has 15 quarters . Each quarter is 1 3/4 mm thick . If Davis stacked up all 15 quarters on top of each other , then 105/4 is the tallness of the stack.
What is Multiplication?multiplication is a method of finding the product of two or more numbers.
Given,
Davis has 15 quarters
Each quarter is [tex]1\frac{3}{4}[/tex] mm thick.
We need to find the height, If Davis stacked up all 15 quarters on top of each other
This can be achieved by adding [tex]1\frac{3}{4}[/tex] for fifteen times or we can use multiplication.
We have to multiply 15 with [tex]1\frac{3}{4}[/tex] .
Firstly [tex]1\frac{3}{4}[/tex] is converted to improper fraction.
[tex]1\frac{3}{4}[/tex] =7/4
Now 7/4×15
=105/4mm
Hence 105/ 4 is the tallness of stack.

Answer:
The correct option is 'No Solution'.
Step-by-step explanation:
Given the system of the equations
[tex]y=\frac{1}{2}x-1[/tex]
[tex]2x-4y=12[/tex]
solving the system of the equations
[tex]\begin{bmatrix}y=\frac{1}{2}x-1\\ 2x-4y=12\end{bmatrix}[/tex]
[tex]\mathrm{Subsititute\:}y=\frac{1}{2}x-1[/tex]
[tex]\begin{bmatrix}2x-4\left(\frac{1}{2}x-1\right)=12\end{bmatrix}[/tex]
[tex]2x-4\left(\frac{1}{2}x-1\right)=12[/tex]
[tex]2x-2x+4=12[/tex]
[tex]4=12[/tex]
as
4=12 is false, therefore the system of equations has no solution.
Therefore, the correct option is 'No Solution'.

dult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score of a man 73.4 inches tall. (to 2 decimal places)
Answer:
The z score is 1.57
Step-by-step explanation:
μ = 69.0, σ = 2.8 and x = 73.4
The objective of the problem is to obtain the z-score of a man 73.4 inches tall. The required z score is derived through the following formula "{x - μ / σ}"
z = 73.4 - 69.0 / 2.8
z = 4.4 / 2.8
z = 1.571428571428571
z = 1.57
Thus, the z score is 1.57.

Answer: -2 is the slope of the equation.
Step-by-step explanation:
5x + 6y = 20 , 8x - 6y = -46
Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.
