To solve problem 19, we must remember the order of operations. PEMDAS tells us that we should simplify numbers in parentheses first, exponents next, multiplication and division after that, and finally addition and subtraction. Using this knowledge, we can begin to simplify the problem by working out the innermost set of parentheses:
36 / [10 - (3-1)²]
36 / [10 - (2)²]
Next, we should still simplify what is inside the parentheses but continue to solve the exponents (the next letter in PEMDAS).
36/ (10-4)
After that, we should compute the subtraction that is inside the parentheses.
36/6
Finally, we can solve using division.
6
Now, we can move onto problem 20:
1/4(16d - 24)
To solve this problem, we need to use the distributive property, which allows us to distribute the coefficient of 1/4 through the parentheses by multiplying each term by 1/4.
1/4 (16d-24)
1/4(16d) - 1/4(24)
Next, we can simplify further by using multiplication.
4d - 6
Therefore, your answer to problem 19 is 6 and the answer to problem 20 is 4d -6.
Hope this helps!

Step-by-step explanation:
is there suppossed to be a chart
The standard deviation is a better measure of spread for movies than it is for basketball games.
<h3>What is box- plot?</h3>
A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.
As, Movies is more centric to mean and not skewed on a particular side whereas basketball games is not centric to mean but is skewed right then left.
Now, Standard deviation just measures the deviation or spread with respect to mean of collected data.
So, In the movies the data is more collected. Thus standard deviation is best suited for movie data.
Now, interquartile range. IQR relies on if the data is skewed.
So, in the basketball data the standard deviation will not give the information.
Hence, the standard deviation is a better measure of spread for movies than it is for basketball games.
