Answer:
3.1623 (sqrt(10))
Step-by-step explanation:
Standard Deviation is calculated by first squaring the differences between the observations and the mean and then taking the square root of the sum of the squares of the differences divided by the number of observations - 1.
Mean = Sum of Observations/Total Observations
Mean = (5 + 7 + 9 + 11 + 13)/5 = 45/5 = 9.
Square of the mean = 9^2 = 81.
Now subtracting the mean from each observation and squaring it gives:
(5 - 9)^2 = (-4)^2 = 16
(7 - 9)^2 = (-2)^2 = 4
(9 - 9)^2 = (0)^2 = 0
(11 - 9)^2 = (2)^2 = 4
(13 - 9)^2 = (4)^2 = 16
Sum of squares = 16 + 4 + 0 + 4 + 16 = 40.
Standard deviation = sqrt(40/4) = sqrt(10) = 3.16 (correct to 2 decimal places).
Therefore, answer is 3.16!!!
" 35% " means " 0.35 ".
" of " in math almost always means " times ".
So the problem is: (0.35) x (60)
You can easily do that with a pencil or a calculator.
In the figure we can identify 2 rays and a point of intersection between them
So the anwer is (b) two rays and an intersecting point
4log6-log2 =
4log(6/2)=
4log3=
log3⁴=
log81= approximately 1.9085
but I think they want you to stop at log 81
