Answer: -4
Step-by-step explanation:
Once you graph it, the solutions are where the graph meets the x axis.
This is at -4 and 9.
Just draw a 3 by 2 block.to explain it you could say there is 2 groups of friends with each 3 people in it
50^2 = 50 to the power of 2 = 2.5 × 10^3
Explanation:
(50) to the 2nd power or simply '50 to the 2nd' is obtained by multiplying 2 times the base 50 by itself. So,
50^2 = 50 × 50 = 2.5 × 10^3
Note: We say that 50 is the base, 2 is the exponent, and the whole thing or the result is a power of 50.
Answer:
Average range(R-bar) = Sum of the sample range for each sample/number of samples = (9+8+1+8+7) /5 = 33/5 = 6.6
Sample size = 8
For a sample size of 8 the factors for control limit for range (D3) = 0.136 (obtained from table of constraints for x-bar and R chart
LCL = R-bar × D3 = 6.6 × 0.136 = 0.90
Step-by-step explanation:
Answer:
This is just multiplying not simplify.
