I will attach the formula for the standard deviation.
N = 8
sum of the squared deviations is 184.
standard deviations = square root of 1/N * sum of squared deviation
standard deviation = √(1/8 * 184)
standard deviation = √23
standard deviation = 4.80
The standard deviation of the data set is 4.80
Answer: Car Rental Company A and B
Step-by-step explanation: Everyone else charges higher prices! Good luck! :D
Answer: D
Step-by-step explanation:
Solve for y: y (greater than or equal to) (7-9x)/5
Slope is negative (-1.8x) so it must be A or D
Choose a test point to plug in. (0,0) works. If plugging in 0 for x and y yields a true inequality, then the area with (0,0) should be shaded. Since the result for plugging in (0,0) is 0 greater than or equal to 1.4, choose the shaded area without (0,0).
