Answer:
Mean: 12.857
Median: 13
Mode: 15
Range: 9
Step-by-step explanation:
First, let's define what each of these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a set of data after being put in ascending order. Mode is the number most frequently seen in a set of data. Range is the difference between the largest and the smallest number in a set of data.
First, let's go ahead and put all our terms in ascending order. It'll look like this: 8, 10, 12, 13, 15, 15, 17.
To find our mean, we'll add up all the terms and divide them by how many there are. First, we'll add up 8 + 10 + 12... and so on for a total of 90. Next, we'll divide 90 by 7 since there are 7 different terms in our set. 90 / 7 should roughly give you a mean of 12.857, but you can round it as needed.
Next, we'll find the median. The median is the number that is in the exact middle of a set once the terms are put in ascending order. Since, we put our terms in order already, we can see that the number in the middle of our set is 13, and I underlined it in the set to give you a visual!
Next, we'll find the mode. The mode is the number most frequently seen in our set of data. Since 15 is listed the most frequently (twice) it is our mode!
Finally, we'll find the range. The range is just the biggest number minus the smallest number. Our biggest number here is 17, and our smallest number here is 8. Just do 17 - 8 for a range of 9. Let me know if you have any other questions!

Answer:
C) x²-2x-15=0
Step-by-step explanation:
You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors. If -3 is a root, one of the factors must be (x+3). If 5 is a root, the other factor must be (x-5).
(x+3)(x-5)
x²-5x+3x-15=0
x²-2x-15=0
Step-by-step explanation:

Answer:
k = 1/4, m = 16Step-by-step explanation:
Scale factor is the ratio of the corresponding sides:
k = 7/28 = 1/4Find m using the scale factor:
m*1/4 = 4m = 16Answer:
scale factor is 4 and m is 16.
Step-by-step explanation:
This is because these are similar rectangles, so the proportion of each side to the congruent side is the same. This means that to get from 7 to 28 u multiply by a scale factor of 4, and to get m you would multiply 4 by 4.

Two plumbers make house calls. One charges $90 for a visit plus $45 per hour of work. The other charges $65
per visit plus $55 per hour of work. For how many hours of work do the two plumbers charge the same? Help!!
The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for

What is 2074 as a percent?
Answer:
207400%
Step-by-step explanation:
Look at the decimal number 2074 as 2074 out of one. Furthermore, percent means per hundred. So the task is to convert 2074 out of one to 2074 out of one hundred.
The equation to solve the problem is displayed below where x is the 2074 as a percentage.
2074
/1
=
x
/100
Please mark brainliest if correct and have a blessed day!
We solve the equation for x above by first multiplying each side by one and then multiplying each side by one hundred. Thus, the answer to 2074 as a percentage is:
207400%
Answer:
the answer is 207400% I do believe
how do I simify by combining like terms
Answer: Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.
Step-by-step explanation:
Answer:
If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.
Step-by-step explanation:
For example this equation:
2x + 7b - 7x + 9b + 1a - 22a
So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them
category x(only numbers that have x's go here): +2x-7x = -5x
category b (only numbers that have b's go here): +7b+9b = +16b
category a (only numbers that have a go here): +1s-22b = -21a
now just put them in the same equation:
-5x+16-21a
and done!^^
Hope this example helped~

What is the greatest common factor of the terms of the polynomial below? 8x^4 - 12x^3 + 20x^2
Answer: I think the greatest common factor is 4x^2
Step-by-step explanation:
Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)

Mei runs 77.4 miles in 5 weeks. If she runs 3 days each week, what is the average distance she runs each day?
The average distance she runs each day is ____ miles.
Answer:
5.16
Step-by-step explanation:
We multiply the number of weeks by the number of days to find the total amount of days that she ran:
5 weeks × 3 days/week = 15 days
We are looking for the amount of miles/day (which represents the number of miles per day).
So, we take [tex]\frac{77.4miles}{15days}[/tex]= 5.16 miles/day
