Answer:
a. Pie chart
This one is the correct option since we use a pie chart when we have categories in the data. And for this case we don't have any category defined at the begin so for this reason the pie chart would be not useful for this case.
Step-by-step explanation:
For this case our variable of interest is the average parking time of its students. And we have 280 values for these times. So then the variable of interest is quantitative.
Which of the following graphs should not be used to display information concerning the students parking times?
a. Pie chart
This one is the correct option since we use a pie chart when we have categories in the data. And for this case we don't have any category defined at the begin so for this reason the pie chart would be not useful for this case.
b.Stem-and-leaf display
That incorrect since the Stem and leaf plot is useful when we want to plot quantitative data.
c. Histogram
That incorrect since the Histogram is ideal when we want to plot quantitative data and analyze the distribution of the data.
d. Box plot
That incorrect since the Box plot is ideal and useful when we want to plot quantitative data and see central tendency measures.
Answer:
Cubic polynomial or binomial
Step-by-step explanation:
3x^2y+5xy^2 is Cubic polynomial or binomial.
Answer:
B. 10/91
Step-by-step explanation:
Box has 5 red buttons and 9 blue buttons.
We add 5 and 9 to get the total buttons.
5 + 9 = 14
Then, we find the probability for a red button.
5/14 = .35
Now, that we've taken out 1 button.
The amount of buttons available changes.
14 - 1 = 13
There are 4 red buttons remaining.
The probability for a red button changes to 4/13.
4/13 = .30
Then, we multiply both probabilities.
.30 x .35 = .111
Convert to a fraction.
.111 = 10/91
Thus it would be B.
hope this helps.
