Option d: Yes, Jacob is correct. The median amount he makes is $84.00 in a day.
Explanation:
It is given that Jacob's daily tips for week are $99, $78, $58, $91, $90, and $68.
We need to determine the median of how much money he makes in daily tips.
Thus, to determine the median, first let us arrange the tips in ascending order.
Ascending order: $58, $68, $78, $90, $91 and $99
Since, the group is an even number of terms, let us add the two middle terms and divide by 2.
Median =
Thus, the median is 84.
Hence, The median amount Jacob makes is $84.00 in a day.
Thus, Option d is the correct answer.
There is a formula which employs the use of determinants and which helps us calculate the area of a triangle if the vertices are given as . The formula is as shown below:
Area=
Now, in our case, we have:
, and
Thus, the area in this case will become:
Area=
Therefore, Area=
We know that area cannot be negative, so the area of the given triangle is <u>10 squared units</u>.
