These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
l-18l=18
Mean: add all the numbers, then dived the sum by hwo many numbers there are.
72.3 + 74.5 + 81.1 + 72.3 + 75.6 + 79 = 754.8
754.8 ÷ 6 = 75.8
Mean = 75.8°
Median: Put all the number in order from lowest to highest. The middle number is the median. If there are two numbers in the middle, add them then divide the sum by 2.
72.3, 72.3, 74.5, 75.6, 79, 81.1
74.5 + 75.6 = 150.1
150.1 ÷ 2 = 75.05 ~ 75
Median = 75°
Answer:

Step-by-step explanation:
Given:
The repair bill includes $355 for parts $146 for labor and a sales tax of $40
Question asked :
what is the total amount we owed = ?
Solution:
Total cost of parts to repair = $355
Total cost of labor = $146
Sales tax =$40
By adding all the cost:
Total cost of repair = $355 + $146 + $40
= $541
Therefore, total amount we have to pay = $541
Answer:
We need to find how much more or less the ratio becomes
1.61 / 23 = 0.07
we multiply 0.07 with 1 to make the ratio even and get your answer
1 x 0.07 = 0.07 on the map
Hope this helps
Step-by-step explanation:
Answer: the trip is 127 1/5 miles
Step-by-step explanation:
The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.
Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles
This means that the total distance that they drove while going is
229/5 + 89/5 = 318/5 miles
If the family drove the same route back home, then the distance traveled during there trip is
2 × 318/5 = 636/5 miles
Converting to mixed fraction, it becomes
127 1/5 miles
