Answer:
- 2x - 24
Step-by-step explanation:
(x + 9)(x - 2) - 9x - 6
- 2x + 9x - 18 - 9x - 6 Multiply.
- 2x - 24 Combine the like terms.
Answer:
Step-by-step explanation:
Given that an automatic machine is set to fill bags of dog food with exactly 25 pounds on average with a standard deviation of 0.5 pounds.
Sample size = n =100
x bar = 24.85 pounds
Sample std error = 
Hypotheses:

(Two tailed test at 5% level)
Mean difference =0.15
Test statistic = mean diff/se = 3
Since population std dev is known z test can be used
p value =0.0000
Since p <0.05 we find that the bag does not contain exactly 25 pounds.
1 and 1/3 is 3/3 and 1/3 so is 4/3 then
4/3 -5/6 they have to have the same denominators so multiply the first fraction with 2/2
(4•2/3•2)-5/6=(8/6)-(5/6)= (8-5)/6=3/6 that you can simplify as 1/2
