Answer:
Step-by-step explanation:
For this case we can calculate all the questions with the following table:
Class Midpoint(Xi) fi Xi*fi Xi^2 *fi
____________________________________
0-3 1.5 6 9 13.5
3-6 4.5 6 27 121.5
6-9 7.5 11 82.5 618.75
9-12 10.5 21 220.5 2315.25
12-25 18.5 5 18 1711.25
_____________________________________
Total 49 431.5 4780.25
We can calculate the expected value with the following formula:
And if we replace we got:
We can calculate the sample variance with the following formula:
And replacing we got:
And the deviation would be just the square root of the variance like this:
An exponential function displays either a growth or decay behavior going from a low steep to a high steep.
In a year she will have $104. 100×.04=4.00 plus the initial $100
You would multiply a single digit from the second number by every number in the first and repeat the process while adding a zero at the end of the next number.
So you would do the equation 528*9 = 4,752 then for the next one your equation would look something like:
528
x002
-------
10,560
The zero at the end being added on. After you do this with all three numbers you get 158400, 10560, and 4752. Add them together and get 173712 and there is your answer: 173,712
72 would be the answer because
6x6=36
36x2/3=24
8x6=48
24+48=72
Therefore <em>f (6)=72</em>
