Answer:

D) There are no outliers.

Step-by-step explanation:

First step is to put the values in order:

15, 20, 25, 30, 35, 40, 45, 45, 50, 55, 60

Then, find the median. 40 is the median because it is in the middle.

A point is considered an outlier if it is greater than 1.5 interquartile ranges below the first quartile or above the third quartile.

To find the first quartile, take the median of all values to the left of 40. The median of 15, 20, 25, 30, 35 is 25 because it is in the middle. So the first quartile is 25.

The third quartile is 50 because it is the middle of the values to the right of 40.

Then, multiply the interquartile range by 1.5

The interquartile range is 25 because the 3rd quartile (50) minus the 1st quartile (25) is 25. Multiply 25 by 1.5 and you get 37.5.

An outlier is anything less than Q1 - 37.5 and anything more than Q3 + 37.5.

Q1 is 25. 25 - 37.5 is -12.5

Q3 is 50. 50 - 37.5 is 12.5

None of the values are outliers because they aren't 12.5 less than Q1 or 12.5 more than Q3.

A company sells boxes of duck calls (d) for $35 and boxes of turkey calls (t) for $45. they make batches of duck calls that fill

SIZIF [17.4K]

Answer:

Option A is the correct choice.

Step-by-step explanation:

Let d be the number of boxes of duck calls and t be the number of boxes of turkey calls.

We have been given that a company sells boxes of duck calls for $35 and boxes of turkey calls (t) for $45, so the revenue earned from selling d boxes of duck and t boxes of turkey call will be 35d and 45t respectively.

Further, the company plan to make $300. We can represent this information as:

$35d+45t=300...(1)$

We are also told that they make batches of duck calls that fill 6 boxes and batches of turkey calls that fill 8 boxes. the company only has 42 boxes. We can represent this information as:

$6d+8t=42...(2)$
