Answer:
$0.60
Step-by-step explanation:
The mean is the average. We add up all the numbers and divide by the number of numbers.
The total for 1st week is $12.48+$9.50+$10.25+$4.99+$8.59 = $45.81
Now, the mean:
Mean = 45.81/5 = $9.162
2nd week's total is 3 more than last week's total, so 2nd week's total is:
45.81 + 3 = $48.81
Now, Mean:
Mean = 48.81/5 = $9.762
The increase is 9.762 - 9.162 = $0.60
Answer:
This is false.
Step-by-step explanation:
90 + 12 = 102.
6(15+12) equals to 6(27) which is 162.
- Slope Formula:
So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:
Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
