Answer:
Left skewed
Step-by-step explanation:
Looking at the box and whisker plot attached showing the wait times and the number of times they occur, we can see that as we approach the left, the number of times the wait time occurs increases. The box plot also shows like as if the box was pushed to the right as the center line is closer to the right than left.
Thus, we can say it's left skewed.
Remember, the number of subsets of a set is 2
, where n is the number of elements in the set. Thus, it is 2³ = 8. If you want a proof for that, ask in comments below.
Tanya spent $9.00 on each item; Tony spent $6.75 on each of his items.
This question more or less tries to trick you with the positive number in parentheses, as you would carry out subtraction as normal. However, since the number you are subtracting from is also negative, it would be easier to think about it as adding two positives, and setting aside the negative symbol for the answer.
-282 - 1017 = -(282 + 1017) = -(1299) = -1299
which is your final answer.
-282 - (+1017) = -1299.
Hope that helped! =)
