find the mean and the median of the following data
number 1: 7, 6, 8, 12 ,15 ,7
number 2: 15 ,200 ,100, 130, 7
number 3: 60, 19, 12, 2 ,7 ,9
Answer:
Hope this helped! <3
Step-by-step explanation:
the median for number 1 is: 7.5 and the mean is 9.16667
the median for number 2 is: 100 and the mean is 90.4
the median for number 3 is: 10.5 and the mean is 18.16667
Answer:
Hi!
number 1: median: 8, 12 or 10
number 2: median: 100
number 3: median: 12, 2 or 7
number 1: mean: 9.16
number 2: mean: 90.4
number 3: mean: 18.16
Step-by-step explanation:
The mean is just all the numbers added up in a data set divided by how many numbers are in the data set. That gets you the average
The median is just the number in the middle of the data set.
Also for the first the median is either 10 or both 8 and 12 Because there's not 1 number in the middle it can be 8 and 12 of you want it averaged them it would be 10 I dont know which you want so you would have to figure that out
same with number 3
Also for the means it might vary depending if you need to round or not
Write an equation for the function that includes the points (1, 18) and (2, 54).
Answer:
y = 36x - 18
Step-by-step explanation:
(1,18) (2,54)
y2 - y1 / x2 - x1
54 - 18 / 2 - 1
36 / 1
= 36
y = 36x + b
18 = 36(1) + b
18 = 36 + b
-18 = b
Solve for X. Round to the nearest tenth.

5 and 5/7 divided by -5
Answer:
-1 and 1/7
Step-by-step explanation:
one way
5 and 5/7 = ((5*7)+5) / 7 = 40/7
(40/7 ) / -5 = (40/7) * (-1/5) = -40/35 = -1 and 5/35 = -1 and 1/7
another way
(5 and 5/7) / -5 = 5/-5 and (5/7) * (1/5) = -1 and 1/7

Which expression is equivalent to 12n - 6x + 48 ?
A. 6 (2n - x + 8 )
B. 6nx +48
C. 2(6n + x ) +48
D. 12n - 6 (x + 4)
Answer:
A. 6 (2n - x +8)
Step-by-step explanation:
Answer:
6(2n-x+8)
Step-by-step explanation:
If a number is in front of the bracket it means times everything on the inside by that number.
So you times everything by 6.
6×2n=12n
6×-x= -6x
6×8=48
Then you put it into an equation:
12n-6x+48

What is the value of A?
Answer:
a = 156
Step-by-step explanation:
24 and a form a straight line so they add to 180 degrees
24 +a = 180
Subtract 24 from each side
24+a-24 = 180-24
a = 156
Three friends will run race. If three friends no ties, in how many distinct order can these 3 friends finish the race?
===========================================================
Explanation:
Let's name the friends A, B, C
If person A is first, then B or C could be second and third.
So we have ABC or ACB as two possible outcomes.
If B is first, then either A is second or C is second. Meaning we have BAC or BCA.
If C is first, then we have CAB or CBA
Overall here are the 6 different ways to have the runners finish
ABC ... A is firstACB ... A is firstBAC ... B is firstBCA ... B is firstCAB ... C is firstCBA ... C is firstNote how for the first slot we have 3 ways to pick the winner. Then after that selection is made, we have 2 choices left, then 1 choice for third place. Therefore, 3*2*1 = 6 different outcomes are possible.
We can use the factorial operation on the calculator to do this with one button press, so we'd say 3! = 6. The exclamation mark means "multiply from 3 down to 1, counting down the whole time".
Another example of a factorial is:
5! = 5*4*3*2*1 = 120

On one side of the square, it is 4.5 units long. The formula in finding the area of a square is A = s^2, where s is for side. The formula can also be A = s * s in which both formulas are the same and will result in the same answer. So overall, the area of the square is 20.25 or 20 ¼ square units. Hope this helps!
The Martz family pays a rate of 37.5 mills the property tax versus value of the home is 68,000 what is the property tax
If the property tax versus value of the home is 68,000 the property tax is $2,550.
Property taxUsing this formula
Property tax=Mills rate× Property value /1000
Where:
Mills rate=37.5
Property value=$68,000
Let plug in the formula
Property tax=37.5×68,000/1000
Property tax=$2,550,000/1000
Property tax=$2,550
Or
Convert the mills rates to dollar rate amounts by dividing the mill rate by 1,000 and then multiply it by the property value.
Property tax=37.5/1000×$68,000
Property tax=$2,550
Inconclusion the property tax is $2,550.

Step-by-step explanation:
At Anthony's school, 260 of the 500 students are girls. At Theresa's school, 360 of the 600 students are girls. Whose school has the greater percent of girls.
Answer:
Theresa school has greater % of girls
Step-by-step explanation:
Given
Number of girl in the Anthony school = 260
Total student in Anthony school = 500
% of girl in the Anthony school = 260/500 * 100 = 52 %
Number of girl in the Theresa school = 360
Total student in Theresa school = 600
% of girl in the Theresa school = 360/600 * 100 = 60%
Theresa school has greater % of girls

Answer: [tex]\frac{7}{8}[/tex] or 0.875 in decimal form.
Step-by-step explanation:
Okay, so to solve this, the easiest method is to find a common denominator. While we could try using trial and error or if you know your tables really well, I don't so we will just multiply the denominators which is 8 and 4. We then multiply 8 and 4 which is 32.
To convert the fractions we have, we multiply both the numerator and denominator of each, by the multiple that multiplies the denominator to 32.
[tex]\frac{2}{4}[/tex] multiply both 4 and 2 by 8. Now we have [tex]\frac{16}{32}[/tex].
Same thing with the second number. We have [tex]\frac{3}{8}[/tex]. We multiply both the numerator and the denominator by 4. 3*4 is 12, 8*4 is 32.
Now we have [tex]\frac{12}{32}[/tex].
Now that both fractions have common denominators, we can add the numerators. [tex]\frac{16}{32} +\frac{12}{32} = \frac{28}{32}[/tex]
Now we have the answer, [tex]\frac{28}{32}[/tex], but is that it?
No. Now to find the final two answers, we simply [tex]\frac{28}{32}[/tex].
To simplify, we find the Greatest Common Factor of 28 and 32, which in this case happens to be 4. This is the highest number that either of those can be divided by to provide a normal whole number
After solving [tex]\frac{28/4}{32/4} =\frac{7}{8}[/tex]
That is our final answer. [tex]\frac{7}{8}[/tex].
If necessary, you can convert it to decimal form through simple division and end up with 0.875.

The driver gear has 4 teeth (T), and its speed is 80 RPM. The driven gear needs a speed of 40 rpm. How many teeth (t) should it have?
The driver gear has 40 teeth (T). The driven gear has 10 teeth (t), and a speed of 12 rpm. What is the speed (RPM) of the driver gear?
Thank you so much!!!
Answer:
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs)
