Find the mean, median, mode and range for the following data set. 1, 3, 5, 9, 8, 5, 8, 6
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and How to solve:-}}}[/tex]
In order to find the mean of a data set, we add all the numbers in the data set and add them, then we divide by how many there are:-
1+3+5+9+8+5+8+6
[tex]\bigstar[/tex] On simplification,
18+8+5+8+645[tex]\bigstar[/tex] Now, divide by 8, because there are 8 numbers in the data set:-
[tex]\bold{\dfrac{45}{8}\:;written\:as\:decimal\Longrightarrow5,625}}}[/tex]
We've found the mean, but we also need to find the median, mode, and range!
The median is the number in the middle, but we should first arrange the data from least to greatest:-
1, 3, 5, 5, 6, 8, 8, 9
Now pick the number in the middle, which is:-
5,6. There are 2 numbers in the middle!
So what we do is we find the mean of the two numbers in the middle:-
5+6=11
11/2 [tex]\Longleftarrow[/tex] median
Now, we don't need to find the mean anymore - the mode and range don't require the mean.
The median requires the mean only when there's an even amount of numbers in the data set.
The mode of a dataset is the number we see the most.
Here we see the number 1 once, the number 3 once, the number 5 appears twice, 6 appears one time only, 8 appears twice and, last but not least, 9 appears once.
So this data set has two modes - 5 and 8.
In order to find the range, we take the smallest number (1) and subtract it from the largest number (9), which results in
8 (range)

A circle with radius 142.5 has an arc with a 24 degree angle. What is the length of the arc?
Answer: 59.690260418206
The result is approximate. Round that value however you need to.
===========================================================
Explanation:
For a circle with radius r = 142.5, the full distance around the edge (aka perimeter aka circumference) is found by using the formula below.
C = 2*pi*r
C = 2*pi*142.5
C = 895.353906273091
That value is approximate. I used my calculator's stored value of pi to get the most accuracy possible.
That value of roughly 895 represents the distance around a full circle of that radius, but we only want a 24 degree pizza slice.
In other words, we want 24/360 = 1/15 of the full perimeter
(1/15)*895.353906273091 = 59.690260418206
Answer:
59.69 units
Step-by-step explanation:
TOTAL circumference of this circle = pi * d = pi * 2r = 895.354
now you want 24 degrees of the entire 360 degrees
24/ 360 * 895.354 = 59.69 units

Using vector concepts, it is found that:
The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.
How can a vector be represented in component notation?Given a magnitude M and angle [tex]\theta[/tex], then a vector V can be represented as follows in component notation:
[tex]V = (M\cos{\theta}, M\sin{\theta})[/tex]
In this problem, the magnitude and the angle are given, respectively, by:
[tex]M = 12, \theta = 143^\circ[/tex]
Hence:
V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).
Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

Using the Factor Theorem, the second degree polynomial function that has a leading coefficient of –1 and root 4 with multiplicity 2 is given by:

In this problem, we have that:
The leading coefficient is of a = -1.There is a root of 4 with multiplicity 2, hence [tex]x_1 = x_2 = 4[/tex].Thus, the polynomial is given by:
f(x) = -(x - 4)(x - 4)

Two mechanics can assemble 10 bicycles in 8 hours. How many bicycles could one mechanic assemble in 8 hours? Use what you determined in part (a) to write the unit rate for one bicycle mechanic to assemble bicycles. Write an equation that relates the rate, bicycles, and time needed for one mechanic. Let t represent time and b represent bicycles assembled. Use your equation to find out how long it would take one mechanic to assemble 25 bicycles.
Using proportions, it is found that one mechanic could assemble 5 bicycles in 8 hours, and it would take 40 hours to assemble 25 bicycles.
The equation is: b = 0.625t.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, two mechanics can assemble 10 bicycles in 8 hours. How many bicycles could one mechanic assemble in 8 hours? Hence the rule of three is given by:
2 mechanics - 10 bicycles.
1 mechanic - x bicycle.
Applying cross multiplication:
2x = 10 -> x = 5 bicycles in 8 hours.
Hence the equation for the number of bicycles in t hours of a single mechanic is given by:
b = 5/8t = 0.625t.
For 25 bicycles, we have that:
25 = 0.625t.
t = 25/0.625.
t = 40 hours.

A contractor has two choices for billing a completed job. · $500 flat rate, regardless of the number of hours worked · $20 per hour worked The graph shows the relationship between pay per hour and number of hours worked for both scenarios. What is the solution to this system of equations, and what does it mean to the contractor?
The solution (0, 20) tells the contractor the minimum amount that can be charged.
The solution (0, 500) tells the contractor the maximum amount that can be charged.
The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
The solution (20, 25) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
The solution to this system of equations is: The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options. (Option C).
What does this mean to the contractor?
It means that if the number of hours worked is above 20, then it is more profitable to utilize the $20/hour rate.
Recall that the contractor has two options for billing a completed job. They are:
500 dollars flat rate20 per work workedLet us fix x hours to be required for completing the project:
Note that:
The total amount recievable per contract is $500 while working on a retail basis, it will cost $25x.
Stating this mathematically, e have
25x < 500 when x < 20.
This mean that
25x < 500 when x < 20.
Then we find that by I contract he would get 500 $ but by II choice he would get 25x dollars
We find that
25x<500 if x<20
This suggests that a $500 flat rate is preferable if the number of hours done is fewer than 20.
If the number of hours is greater than 20, the hourly rate, i.e. $20 per hour, is preferable.If number of hours is more than 20, hourly rate i.e. 20 per hour is better.Hence the correct answer is Option C.
