Answer: 20
Step-by-step explanation:
Formula to find the minimum sample size(n) when prior population standard deviation is known.
, where E = Margin of error , = Critical z-value for c confidence interval.
Given : E = 225 g , g
Critical z value for 90% confidence = 1.645
Now,
Hence, the required minimum sample size = 20
AB is 6 because of the definition of a midsegment 1/2(12)
Given;
40 fluid ounces of iced tea.
We know,
1 cup = 8 fluid ounce
1 pint = 2 cup
Now,
8 fluid ounce = 1 cup
1 fluid ounce = 1 / 8 cup
40 fluid ounce = (1 / 8) * 40 cup
So, 40 fluid ounce = 5 cup
Now,
We, used 3 cups of iced tea. So, we only have 2 cups of iced tea left.
We have,
2 cups = 1 pint
So, 1 pint of iced tea is left!
