Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A () = 0.33
Variance of activity B () = 0.67
Variance of activity C () = 0.33
Variance of activity D () = 0.17
Thus the standard deviation on the critical path () = + + +
= + + +
= 0.6956
= 0.834
The standard deviation on the critical path = 0.834
We know that there are two tickets (which we'll represent with x) and a fee for transporation (which is $20)
So we can set up the equation 20+2x=48
We want to isolate x so we'll subtract 20 from each side, which gives us the equation
2x=28
Then divide each side by 2
Giving us the final answer of
x=14
So each ticket costs $14
In constructing a frequency table, first you'll need to arrange your data from lowest to highest and solve for the following: range, class width, and class size.
Range: Highest Value - Lowest Value in the data set.
= 18 - 0 = 0
Class Width: Square root of the total number of data. In the data set, we have 14 numbers. This is the number of classes.
= sqrt (14) = 3.7 or 4
Class Size: Range divided by Class Width.
=18/4 = 4.5 or 5. There should be five numbers inside each class.
The Frequency Table is below.
Eagles | Frequency
0-4 4
5-9 5
10-14 3
15-19 2
