Answer:
[1] 8
[2] 10
[3] 8.5
[4] 8
Step-by-step explanation:
[1] What is the mode of the data set?
5,8,8,8,8,9,9,9,10,10
Answer = 8
Explanation: Mode = Appears Most
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[2] How many people were in the sample?
Answer = 10
Explanation:
Each x = 1 person
Hence, it a total of 10 "x" (10 People)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[3] What is the median of the data set?
5,8,8,8,8,9,9,9,10,10
Answer = 8.5
Explanation:
Median = Middle
5,8,8,8,8,9,9,9,10,10
5,8,8,8,8,9,9,9,10,10
8 + 9 = 17/2 = 8.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[4] What is the mean for the data set, to the nearest whole number?
Answer = 8
Explanation:
Mean = Add up all data values to get the sum and Count the number of values in your data set. Divide the sum by the count
5 + 8 + 8 +8 + 8 + 9 + 9 + 9 + 10 + 10 = 84/10=8.4
8.4 Round = 8

Answer:
Step-by-step explanation:
1) point slope form is:
y-y1=m(x-x1)
y1=8
x1=4
m=(slope)
to find m: y2-y1/x2-x1
hence
-2-8/2-4=-10/-2=5
m=5:
y-8=5(x+4)
The answer is -5 hope this helps
Answer:
13.695 m
Step-by-step explanation:
The assumption made here is that the boat/water interface is essentially frictionless, so that the center of mass of the system remains in the same place as the occupant of the boat moves around.
__
We can find the sum of the moments of boat and child about the pier end:
(46 kg)(7.6 m) + (80 kg)((7.6 +9.6/2) m) = 1341.6 kg·m
After the child moves, the center of mass of boat and child is presumed to remain in the same place. If x is the new distance from the pier to the child, the sum of moments is now ...
46x +80(x-4.8)* = 1341.6
126x -384 = 1341.6
x = (1341.6 +384)/126 = 13 73/105 ≈ 13.695 . . . meters
The child is about 13.695 meters from the pier when she reaches the far end of the boat.
_____
* The center of mass of the boat alone is half its length closer to the pier than is the child, so is located at x-4.8 meters.
Answer: 1.3
Step-by-step explanation:
If u subtract 6-4.7 u will get 1.3 and you can also do it for all and u will still get the same answer
