It would be 7.54 because you fist have to put the numbers ordered smallest to biggest amount 7.15, 7.44, 7.48,7.60, 7.72, 7.73 so the numbers that are in the middle are 7.48 and 7.60 you add them up, and the result you divide by 2 which gives you 7.54.
Answer:
x = 4
Step-by-step explanation:
The parallel segment divides the 2 sides of the triangle proportionally, that is
= ( cross- multiply )
12x = 48 ( divide both sides by 12 )
x = 4
Answer:
is a multiple of 4
Step-by-step explanation:
Let's think about this.
Even numbers are basically numbers that, when divided by 2, get us an integer.
This means that must be an even integer.
<em>However,</em>
Every other even number, when divided by 2, gets you an odd integer.
This means that every second even number, gets us an even number.
This also means that every time is an even number, n will be a multiple of 4 (as ).
Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)
Hope this helped!
You can compute both the mean and second moment directly using the density function; in this case, it's
Then the mean (first moment) is
and the second moment is
The second moment is useful in finding the variance, which is given by
You get the standard deviation by taking the square root of the variance, and so
