it isn't random. Students who buy hot lunch probably like it. if you don't survey other peoples answers from cold lunch then you won't have a equal answer.
its right. if you read the question this answer would make sense
we've all done it once in our life
A) complete a detailed investigation of a topic

D)search for different types of sources"
lol but a whole lot less (also please don't answer the question if you want to see the chaos look it up)

No, the sample is not random. It only includes a specific group of students (those who buy hot lunch on a particular day), which could lead to sampling bias. A truly random sample would include all students who buy lunch at the cafeteria on different days to make sure that the sample accurately represents the student population. By doing so, the sample would be more generalizable and less prone to any bias.

Therefore, the estimated number of students in the school who most likely prefer chocolate ice cream is 750.
Let "x" be the total number of squirrels in the area.
Then, we can set up the following proportion:
Number of tagged squirrels / Total number of squirrels = Number of recaptured tagged squirrels / Total number of recaptured squirrels
Simplifying this proportion, we get:
150/x = 12/300
Cross-multiplying and solving for "x", we get:
x = 3750
Therefore, we can estimate that there are approximately 3750 squirrels in the area.
A histogram is a graphical representation of a frequency distribution that is divided into intervals called bins. It is particularly useful for representing data that are continuous, as in the case of the number of daily 911 calls made during a month. In a histogram, the height of each bar represents the frequency of observations falling within the corresponding bin.
By using a histogram, you can easily identify the bin with the highest frequency, which corresponds to the mode of the dataset.
Therefore, the estimated number of middle school students at Kings High School who will select French fries as their favorite fast food item is 147.
