A possible question is: Determine the total number of votes by Brett
We have that:

So:

Substitute 314 for Rosa


Another possible question is: Determine the total number of voters.
This is done by:



Answer:
C
Step-by-step explanation:
0.000008 = 8x10^-6
Count how many moves will take the decimal point from it's current position to the right of 8.
That's 6 times.
Or simply count the total number of zeros before 8.
Answer:
Step-by-step explanation:
-30n - 65 + 2 - 43
-30n - 63 - 43
-30n - 106
Multiply -3 to x and get -3x and multiply 4 and -3 and get -12 so then subtract -12 and 15 and get -3 so now it is -3x-3=6-4y so now. You subtract -3 and 6 and get positive 3 so now the final answer is -3x-4y+3
Answer: 0.3413
Step-by-step explanation:
Given: an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds.
Let
.
Let x be the random variable that denotes the amount of newspaper for garbage generated by each household each month.
If the data conforms to a normal distribution and a household is selected at random, the probability of its generating between 28 and 30 pounds per month is about

Hence, the required probability is 0.3413.
