Answer:
c) 44000 miles
Step-by-step explanation:
The regression line has the following format:
In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.
In this problem, we have that:
. So
A person who spent $ 2000 is predicted to have flown:
This is y when x = 2000.
So the correct answer is:
c) 44000 miles
C. eight or fewer
99% means 99/100
. with 9 alarms there is no way you can trigger 8 alarms with that 99% rate
First to find the median we need to put the numbers in order from least to greatest.
62, 64, 65, 66, 67, 69, 83
Now take a number from each side
64, 65, 66, 67, 69
Once again.
65, 66, 67
On last time
66
So the median is 66.
Now to find the mean we must add all the numbers up
64+67+83+65+66+62+69
which equals 476
Now divide 476 by the total number of heights which is 7
476/7=68
So the mean is 68
Answers: Mean; 68 Median; 66
Answer:
- 4099 yes
- 4110 no
- 5909 no
- 5011 yes
Step-by-step explanation:
The digits will be related by a factor of 10 if they are the same digit. 4099 and 5011 have the same digit in the tens and ones places. 4110 and 5909 do not.
