Answer:
Mean: Use any 5 numbers that make 25.
Median: 5
Step-by-step explanation:
For the mean you can use 2.5+2.5+2.5+7.5+10
I'm not sure about the median... If it's asking about the median for the set I used, it would be 2.5. If it's asking about the one gives, not including the zero would be 5.
To find the area you would had to do a an triangle formula so the final answer would be 63 inches
Sx is the standard deviation of the x values and sy is the standard deviation of the y values. If you can use a calculator put the values in list one and list two then do 1 variable stats on list 1 then again on list 2
Answer:
The expression giving her net earnings for a day with more than 8 hours worked is X = 80 + 15H, where H means "extra hours worked".
Step-by-step explanation:
Given that Daisy works at an ice-cream parlor earning $10 per hour for the first 8 hours she works in a day, and 1.5 times her hourly wage for every extra hour she works, in order to know how much can she make in a day working more than 8 hours the following equation has to be made:
X = (8 x 10) + (H x (1.5 x 10))
X = 80 + 15H
Therefore, if Daisy works 13 hours, the equation works as follows:
X = 80 + 15x13
X = 80 + 195
X = 275
