Given the following values, which point would be considered an outlier?
(2, 2.1)
(4, 3.8)
(6, 8.4)
(9, 9)
The point (6, 8.4) would be considered an outlier as it significantly deviates from the general pattern of the other points.
A scientist is growing bacteria in a petri dish. The scatter plot below shows the number of bacteria in the dish over time. src="/content/media/941080-7302013-102503-AM-1870693195.jpg"
If this growth trend continues, approximately how many bacteria would be in the petri dish on day 10?
75
175
275
375
It is difficult to accurately estimate the number of bacteria on day 10 based on the given scatter plot. However, if we assume that the trend in the scatter plot continues, it appears that the number of bacteria doubles about every 2 days. Using this assumption, we can estimate that there would be approximately 300 bacteria in the dish on day 10. Therefore, the closest answer choice would be 275.
Carol has a collection of 100 stamps. The graph below shows the percentage of stamps she has from each country. alt="A pie graph, titled 'Carol's Stamp Collection is shown. The graph is divided into 4 sectors. The largest sector is labeled 'Norway 29 percent.' The second largest is labeled 'Italy 25 percent.' The third largest sector is labeled 'France 24 percent.' The final sector is labeled 'England 22 percent.'"
How many more of Carol’s stamps are from Italy than from England?
22 stamps
25 stamps
47 stamps
3 stamps
We can start by calculating the number of stamps Carol has from each country based on the percentages given in the pie chart:
- Norway: 29% of 100 stamps = 0.29 x 100 = 29 stamps
- Italy: 25% of 100 stamps = 0.25 x 100 = 25 stamps
- France: 24% of 100 stamps = 0.24 x 100 = 24 stamps
- England: 22% of 100 stamps = 0.22 x 100 = 22 stamps
To find out how many more stamps Carol has from Italy than from England, we can subtract the number of stamps from England (22) from the number of stamps from Italy (25):
25 - 22 = 3 stamps
Therefore, Carol has 3 more stamps from Italy than from England. The answer is 3 stamps.
A survey about the student government program at a school finds the following results:
110 students like the program.
120 students think the program is unnecessary.
210 students plan on running for student government next year.
If a circle graph were made from this data, what would the measure of the central angle be for the group that thinks the program is unnecessary?
98º
27º
90º
172º
The first step is to calculate the total number of students surveyed:
110 + 120 + 210 = 440 students
Next, we can calculate the percentage of students in the survey that think the program is unnecessary:
120/440 x 100% = 27.27%
To convert this percentage to a central angle, we can use the formula:
central angle = percentage/100% x 360º
central angle = 27.27/100 x 360º
central angle ≈ 98º
Therefore, the measure of the central angle for the group that thinks the program is unnecessary is about 98º. Answer: 98º.
