Answer:
Step-by-step explanation:
<u>The Sum:</u>
- 3x²y - 5a + 4b + (-9x²y - 7b + 4a) =
- 3x²y - 9x²y - 5a + 4a + 4b - 7b =
- -6x²y - a - 3b
<u>The difference:</u>
- 3x²y - 5a + 4b - (-9x²y - 7b + 4a) =
- 3x²y + 9x²y - 5a - 4a + 4b + 7b =
- 12x²y - 9a + 11b
<u>Subtract the sum from the difference:</u>
- 12x²y - 9a + 11b - (-6x²y - a - 3b) =
- 12x²y + 6x²y - 9a + a + 11b + 3b =
- 18x²y - 8a + 14b

Answer:
Step-by-step explanation:
Given that an inspector inspects large truckloads of potatoes to determine the proportion p in the shipment with major defects prior to using the potatoes to make potato chips.
n =100
SE = 
Sample P = 6 out of 100 = 0.06
p difference = -0.04
p value = 0.484
Since p value >0.05 we accept null hypothesis
