The constant of proportionality stays the same no matter what values the variables take, so in our example independently of the cost of the item (and of the tax value, which is dependent on the cost value).
Here the only value that does not change is the 0.007, the rate! - this is the correct answer.
Answer:
D) $110 and $190
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 150
Standard deviation = 20
95% of the monthly food expenditures are between what two amounts?
By the Empirical Rule, within 2 standard deviations of the mean
150 - 2*20 = $110
150 + 2*20 = $190
So the correct answer is:
D) $110 and $190
I think none of the above
Answer:
The answer is 600
Step-by-step explanation:
Front end estimation is a method of rounding use to make operations more easily and obtain approximate answers. Is called front end because we take the first digit of the number or the "front digit" and round our number to the nearest value detemined by our front end digit, making zeros the other numbers until the end.
In your case we have:
788.44 - 7 is the front number - in hundreds place - we round to nearest hundred 788.44 and this is 800.
225.6 - 1 is the front number - in hundreds place - we round to nearest hundred 225.6 and this is 200.
We perform the operation and obtain : 800-200 = 600.
