The mean is the average, add the numbers together and divide by the number of students asked:
Mean = 4 + 15 + 19+ 11 + 6 + 16 + 9 + 15 = 95/8 = 11.875 rounded to the nearest tenth = 11.9
Median is the middle value, list the numbers from smallest to largest:
4, 6, 9, 11, 15, 15, 16, 19
There ia an even number, so find the middle two numbers, add them together and divide by 2:
Median = 11 + 15 = 26 / 2 = 13
Answer:
highest number is 118
middle number is 100
lowest number is 94
Step-by-step explanation:
R=24---between high and low is 24 numbers
M=104---average of the three numbers
highest number is 118
therefore if you subtract 24 from 118 therefore the lowest number is 94
Then i used a mean calculator and went up from 95 to 100 before the means matched.
Answer:
The correct answer is D
Multiply by 1000 and divide by 3600
Step-by-step explanation:
We know that in 1 km we have 1000 m and in 1 h we have 60 minutes and each minute have 60 seconds, then we multiply 60*60 to know how many seconds are in an hour and we have that 1 h have 3600 s. Using a conversion factor we have:
With this we can see that to convert a quantity from kn/h to m/s we must multiply by 1000 and divide by 36000
The answer to your question is x=18
I'm guessing on the make up of the matrices.
First off let's look at [C][F].
[C]=
[F]=
[C][F]=
where each element of [C][F] comes from multiplying a row of [C] with a column of [F].
Example: First element is product of first row and first column.
.
.
.
Now that we have [C][F], we can subtract it from [B], element by element,
[B]-[C][F]=
[B]-[C][F]=
.
.
.
If this is not how the matrices look,please re-state the problem and be more specific about the make up of the matrices (rows x columns).
Here's an example.
[A] is a 2x2 matrix. A=[1,2,3,4].
The assumption is that [A] looks like this,
[A]=
[B] is a 3x2 matrix. B=[5,6,7,8,9,10]
[B]=
