A right rectangular prism can be used to simulate an aquarium. Its measurements are 14 by 7 by 4 inches. If there are 153 cubic inches of water in the aquarium, There is a 61 % empty space.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The volume of the aquarium is;

V=14 × 7 × 4 = 392 inch³

The % by which the container is empty is found as;

$\%Empty= \frac{392-153}{392} \times 100 \ \\\\ \%Empty= \frac{239}{392} \times 100 \\\\ \%Empty= 61\%$

Hence, there is a 61 % empty space.

The equation for the determination of the z-score is shown below.
z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation.
Substituting the known values,
z-score = (1,030.00 - 1,200) / 100 = -1.7
Therefore, the z-score of 1,030 is -1.7.

98, 78 , 84, 75, 91

The interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1.

****************************************************
Step 1: Put the numbers in order.
75, 78, 84, 91, 98

Step 2: Find the median.
75, 78, 84, 91, 98

Step 3: Place parentheses around the numbers above and below the median. 
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(75, 78), 84, (91, 98)

Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(75, 78), 84, (91, 98)

*(75, 78) ---> (75 + 78) ÷ 2 = 76.5
*(91, 98) ---> (91 + 98) ÷ 2 = 94.5

Step 5: Subtract Q1 from Q3 to find the interquartile range.
94.5 – 76.5 = 18

IQR = 18
