Answer:
15 two-point questions and 5 four-point questions.
Step-by-step explanation:
Let x represent number of two-points questions and y represent number of four-points questions.
We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:
Since all questions are worth 50 points. We can represent this information in an equation as:
From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, there are 5 questions that are worth 4 points each.
Now, we will substitute in equation (1) to solve for x.
Therefore, there are 15 questions that are worth 2 points each.
Answer:
59
Step-by-step explanation:
F = 1.8c + 32
F = 1.8(15) + 32
F = 27+32
F = 59
Answer:
The IQR of the given data is 6. Therefore the correct option is B.
Step-by-step explanation:
The formula for interquartile range is
In a box plot the left end of line represents the minimum value of data set and right end of line represents the maximum value of data set.
The left end of box represents the first quartile and right end of the box represents the third quartile. The line between the box represent the median.
From the given box plot it is clear that,
The interquartile range of the data is
The IQR of the given data is 6. Therefore the correct option is B.
