The most appropriate choice for percentage will be given by-
a)Percentage of people arrive at their office before 7 am = 10%
b)Percentage of people arrive at their office after 7:59 am = 64 %
What is percentage?
Suppose, there is ratio of two numbers and it has to be expressed as a fraction of 100, percentage is that ratio.
So percentage is the ratio of two numbers expressed as a fraction of 100.
Here,
a) Number of people arrive at their office before 7 am = 15
Total number of people = 15 + 39 + 75 + 21
= 150
Percentage of people arrive at their office before 7 am = [tex]\frac{15}{150}\times 100[/tex]
= 10%
b)Number of people arrive at their office after 7:59 am = 75 + 21
= 96
Percentage of people arrive at their office after 7:59 am = [tex]\frac{96}{150}\times 100[/tex]
= 64 %

order the following mumbers from least to greatest 1 8/251.35/4
Answer
(5/4) < 1.3 < 1 (8/25)
Explanation
We are told to order the given numbers from the least to the greatest number.
To do that, we will need to express the numbers in decimal form, so it is evident which one is bigger.
1 (8/25)
= 1 + (0.32)
= 1.32
1.3
= 1.30
(5/4)
= 1.25
We can easily see that
1.25 < 1.30 < 1.32
In the form of the numbers given, we have
(5/4) < 1.3 < 1 (8/25)

Mike Lasueze is a salesperson in the appliance department at Wicklow Appliance Inc. He is guaranteed a minimum salary of $220 per week or 5.5% of his total sales, whichever is greater. What is his gross pay for a week in which his total sales were $8,400?
For a sale of $8400 made his gross pay is $373.21
In this question, we have been given Mike Lasueze is guaranteed a minimum salary of $220 per week or 5.5 percent of his total sales, whichever is greater.
We need to find his gross pay for a week in which his total sales were $8,400
weekly pay = $220
commission = 5.5% of sales
= 0.055 of sales
Let m be the total sale and his gross pay be represented by y.
So, we get an equation for the total/gross pay:
y = 0.055x + 220
Required is the gross pay y for x = 8400
y = 0.055(8400) + 220
y = 682
Therefore, for a sale of $8400 made his gross pay is $373.21

suppose there are two candidates for elected office. explain how the facts that a) voting might not be compulsory and b) resources are needed to finance reelection campaigns affect the conclusions of the median voter model.
The fact that voting might not be compulsory will make the voter ranks the candidate as their proximity, and the median voter wins the vote
The fact that resources are needed to finance reelection campaigns will make the probability of the median voter be in danger
According to median voter model theorem, at-least there must be two candidates
Being that we have two candidates for elected office, let's see how the following may affect the conclusions of the median voter model:
Part a
Voting might not be compulsory:
Here, voter ranks the candidates as per as their proximity, and the median voter will win the vote.
Part b
Resources are needed to finance re-election campaign :
When resources are needed to finance reelection campaign, none can cast their votes and it will distort this strategy. So the probability of median voter is in danger.

Use the matrices to show that matrix multiplication is associative.
Drag a matrix to each box to correctly complete the equations.
Since the multiplication of the matrices (A x B) x C and A x (B x C) are equal, the multiplication of matrices is associative.
How to multiply matrices?Matrices are multiplied multiplying the lines of the first matrix by the columns of the second matrix.
The multiplication of the matrices being associative means that:
(A x B) x C = A x (B x C).
Hence, applying the rules, of the multiplication of the lines by the columns, we have to solve for the two cases, and find the results.
Then:
[tex](AB)C = \left[\begin{array}{ccc}11&-8&37\\21&28&15\end{array}\right] \times \left[\begin{array}{c}1\\-2\\0\end{array}\right][/tex]
As the multiplication of a 2 x 2 matrix by a 2 x 3 matrix results in a 2 x 3 matrix, and then we multiply by C as follows:
[tex]\left[\begin{array}{ccc}11&-8&37\\21&28&15\end{array}\right] \times \left[\begin{array}{c}1\\-2\\0\end{array}\right] = \left[\begin{array}{c}27\\-35\\\end{array}\right][/tex]
Multiplying the lines by the columns, we have that the first line is, for example:
11 x 1 - 8 x (-2) + 37 x 0 = 27.
In the second case, the multiplication of B and C is given by:
[tex]BC = \left[\begin{array}{c}5\\-8\end{array}\right][/tex]
Multiplying by A, we get the same result as above, hence the multiplication of matrices is associative.

a potter forms a piece of clay into a right circular cylinder. as she rolls it, the height h of the cylinder increases and the radius r decreases. assume that no clay is lost in the process. suppose the height of the cylinder is increasing by 0.5 centimeters per second. what is the rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters?
The rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters is -0.8571 cm/s
dr/dt = -0.8571 cm/s
A cylinder's volume can be calculated using...
V = πr²h
For a constant volume, by differentiating with respect to t, we obtain...
0 = π(2rh·dr/dt + r²·dh/dt)
Finding for dr/dt, we have ...
dr/dt = dh/dt(-r²/(2rh)) = (dh/dt)(-r/(2h))
Filling in the given numbers gives ...
dr/dt = (0.5 cm/s)(-7 cm)/(2·6 cm)
dr/dt = -0.8571 cm/s
