Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages.
In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages.
After subtracting Nelson's 240, Jennifer is then found to have read 225 pages.
B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does.
Hope this helped. Khan Academy is a great resource for any learner. :)
Answer:
4(240 + p) = 1860
225 pages.
Step-by-step explanation
4(240 + p) = 1860
960 + 4p = 1860
4p = 1860 - 960
4p = 900
p = 225.

The number of students walk to school is 378.
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
For the given situation,
The total number of students = 540
Percentage of students walk to school = 70% = 0.70
Number of students walk to school = [tex]540(0.70)[/tex]
⇒ [tex]378[/tex]
Hence we can conclude that the number of students walk to school is 378.

The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
1.5
2.2
3.0
4.6
Answers
Answer:
The number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:
3.0
In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.
The MAD of first set of data is: 1.2
and MAD of second set of data is: 0.4
Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.

B. It is not randomly chosen.
C. It results in incorrect predictions.
D. It does not accurately represent the population.
Answers
Answer:
i think it is B
Step-by-step explanation:
bias means you have an opinion on something and you make choices on it so a biased sample would not randomly chosen
The correct option is:
D.) It does not accurately represent the population.
What is sampling?In statistical analysis, sampling is the procedure by which researchers select a specific number of observations from a larger population. The sample strategy will depend on the sort of study being done, although it may involve systematic sampling or just plain random sampling.
It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of its groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased.
Hence, option C is correct.
