Answer:
Conditional relative frequency = 0.67
Step-by-step explanation:
50% off Buy 1, get 1 free Total
Item 1 12 8 20
Item 2 20 10 30
Total 32 18 50
Condition relative frequency table:
50% off Buy 1, get 1 free Total
Item 1
Item 2
Total
Therefore, conditional relative frequency of selling an item marked 50% off, provided the item sold is item 2 = 0.67
The magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively
The formula for calculating the resultant vector is expressed as:
Given the following distances:
u = -5√3 feet (west direction)
v = 5 feet
Substitute the given values into the formula above;
The magnitude of the resultant vector is 10feet
Get the direction:
Since tan is negative in the second quadrant, hence;
Hence the magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively.
