Step-by-step explanation:
I count four 6s, four 4s and three b.
so, we have
6⁴×4⁴×b³ or (using the same symbols as above)
6⁴.4⁴.b³
Answer:
14
Step-by-step explanation: Multiply 56 by 75% then subtract your product from 56
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64
Therefore, a = 16.
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
