Answer:
78
Step-by-step explanation:
The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78
Convert 7/11 to a decimal value.
7 divided by 11 = 0.636364
Subtract 0.636364 to 0.757576 and divide the difference
by 2.
Following the equation, 0.636364 - 0.757576 =
0.121212.
<span>0.121212 divided by 2, the quotient is 0.06 (06
is repeating) </span>

Answer:
$48.00
Step-by-step explanation:
$3.00 / 6.5 oz = [unknown $] / 104 oz
unknown $ = 104 oz * $3.00 / 6.5 oz
unknown $ = 16 * $3.00 ((oz/oz cancels out))
unknown $ = $48.00
