Answer:
Wallace deliver <u>14 gallons</u> of orange juice.
Step-by-step explanation:
Given:
Wallace delivered 7 containers of orange juice to the Apple Tree Restaurant. Each container had 8 quarts of orange juice.
Now, to find the gallons of orange juice Wallace deliver.
As given that each containers had 8 quarts of juice.
So, we get the total quarts of juice first of the 7 containers by multiplying:
Number of containers × Numbers of quarts.
Now, to get the quantity in gallons we convert the unit of quarts to gallon by dividing as we are changing units from lower to higher:
<u>1 gallon = 4 quarts.</u>
<em>So, by dividing 56 quarts by 4 we get:</em>
Therefore, Wallace deliver 14 gallons of orange juice.
Answer:
720 divided by 90
Step-by-step explanation:
72 divided by 9 is 8. 720 divided by 9 is 80 because you're keeping the 0, but when dividing, take away the zeros if both numbers have a zero to make it easier
Answer:
The upper limit of a 95% confidence interval for the population mean would equal 83.805.
Step-by-step explanation:
The standard deviation is the square root of the variance. Since the variance is 25, the sample's standard deviation is 5.
We have the sample standard deviation, not the population, so we use the t-distribution to solve this question.
T interval:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 15 - 1 = 14
Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of 0.95(). So we have T = 1.761
The margin of error is:
M = T*s = 1.761*5 = 8.805.
The upper end of the interval is the sample mean added to M. So it is 75 + 8.805 = 83.805.
The upper limit of a 95% confidence interval for the population mean would equal 83.805.
Answer:
Step-by-step explanation:
Ratios of perimeters is a one-to-one measure. From the figure on the left to the one on the right the ratio of the one-to-one measure is 45/25 which reduces to 9/5.
Area is a squared measure. Once we have the perimeter reduced (we do), we square those perimeter measures to find the area ratio.
