Answer:
Step-by-step explanation:
-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:
Where:
is the standard deviation
is the desired margin of error.
We substitute our given values to calculate the sample size:
Hence, the smallest desired sample size is 23
Answer:
2 liters of orange juice
Step-by-step explanation:
We know that Gaby drank 3/4 liters of juice
3/4 liters is the same as saying 0.75 liters
3/4 = 0.75
if 0.75 is 3/8 of the container we just have to divide it by 3 and multiply it by 8 and so we will get the liters of the container
(0.75/3) * 8 =
0.25 * 8 =
2
then initially in the container there were 2 liters of orange juice
Answer:
I believe it's $1,040.
Step-by-step explanation:
So, the original price is $1,300. If we subtract $1,300 by 20% the result should be $1,040.
Therefore, the discounted of the price would be $1,040.
Since x - 3 < 0 for -2 < x < 3, |x-3| = -(x-3)
Since x + 2 > 0 for -2 < x < 3, |x+2| = x+2
Since x - 5 < 0 for -2 < x < 3, |x-5| = -(x-5).
So y = -(x-3) + (x+2) -(-(x-5)) = 3 - x + x + 2 + x - 5 = x.
y = x, if -2 < x < 3.
