Answer:
-0.2,-2.2,-0.2, 0.8, 1.8
Step-by-step explanation:
Given :Five people were asked approximately how many hours of TV they watched per week.
Their responses were as follows. 6 4 6 7 8
To Find : Find the deviations from the mean for these five data values
Solution :
Mean = 
Mean = 
Mean = 
The deviations from the mean for these five data values: 6-6.2,4-6.2,6-6.2,7-6.2,8-6.2=-0.2,-2.2,-0.2, 0.8, 1.8
Hence the deviations from the mean for these five data values is -0.2,-2.2,-0.2, 0.8, 1.8
Answer:
10cm 5cm and 9cm
Step-by-step explanation:
just try this
take any two measurements and add them together if they are larger than the 3rd measurement it will work and all you have to do is do that to each measurement
10+5 is greater than 9
9+5 is greater than 10
9+10 is greater than 5
1) It takes him ac minutes to run his train(s) around the track.
a being the time it takes to move ONE train around the track,
c being the number of trains.
When he has 5 trains, it is just 5 times that, since they are both proportional.
5ac
2) A) EG corresponds with BD, since they are both the hypotenuse.
Answer:
Added thanks lol :)
Step-by-step explanation:
Step-by-step explanation:
a = 1, b = 9, c = 8
with the quadratic formula;
x = -9 + \|9² - 4(1 × 8) ÷ 2(1) or x = -9 - \|9² - 4(1 × 8) ÷ 2(1)
x = -9 + \| 81 - 32 ÷ 2 or x = -9 - \| 81 - 32 ÷ 2
x = -9 + \| 49 ÷ 2 or x = -9 - \| 49 ÷ 2
x = -9 + 7 ÷ 2 or x = -9 - 7 ÷ 2
x = -2 ÷ 2 or x = -16 ÷ 2
x = -1 or x = -8
