(1,-4)
Answer:
1.1m
Step-by-step explanation:
Let L denote longer pipe and S denote shorter part
given:
L:S = 9:2
or L/S = 9/2
2L = 9S
S = (2/9)L-----(eq 1)
Also given:
L - 1.65 = 3S
L - 3S = 1.65 ----- (eq 2)
By substitution, sub eq 1 into eq 2
L - 3(2/9)L = 1.65
L - (2/3)L = 1.65
L [ 1 - (2/3) ] = 1.65
L/3 = 1.65
L = 1.65 (3) = 4.95 (substitute into equation 1)
S = (2/9)(4.95) = 1.1m
Answer:
Average: 11.4 Miles Median: 9 Range is 20 or (5,25)
Step-by-step explanation:
AVERAGE)
Add all of the miles up for the week and divide by the number of days he ran so it'd look like this: 8 + 5+ 9+ 10+ 25 = 57
Now, divide the 57 by 5 days to get 11.4
MEDIAN
Organize your list of numbers from least to greatest
It'd look like this: 5,8,9,10,25
Now cross out one number on each end until you get to the middle.
so you cross out 5 and 25. Then you are left with 8,9,10. Cross out 8 and 10. Your final answer should be 9
RANGE
This is the difference between the highest and lowest # (unless it is for a function- then it is the range of y-values).
If this has a graph to go with it look up the way it wants you to write the range, you can write it as (5,25)
Either 175.25 ( 175.2 + 0.1/2) or 175.15 ( 175.2 - 0.1/2) ----------> Range. 175.15 < weight < 175.25
The correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.
<h3>What is mean?</h3>
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The difference between the mean times is about 16 times the mean absolute deviation of the data set.
127.9-127.4=0.5
0.26-0.23=0.03
0.5/0.03=16.6666
We can see that the ratio of the mean times difference is 16 times the mean deviation by solving the above.
Therefore the correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.
