Solution Steps

Step 1: Calculate the Total Number of Books Read

To find the mean number of books read, we first need to calculate the total number of books read by all students. We do this by multiplying the number of students by the number of books read per student and then summing these products.

\[ \text{Total books read} = (4 \times 2) + (10 \times 3) + (13 \times 4) \]

\[ = 8 + 30 + 52 = 90 \]

Step 2: Calculate the Total Number of Students

The total number of students is given by the sum of the number of students in each category:

\[ \text{Total number of students} = 4 + 10 + 13 = 27 \]

Step 3: Calculate the Mean Number of Books Read

The mean number of books read is calculated by dividing the total number of books read by the total number of students:

\[ \text{Mean number of books read} = \frac{\text{Total books read}}{\text{Total number of students}} = \frac{90}{27} \approx 3.3333 \]

Rounding to the nearest tenth, the mean number of books read is 3.3.

Final Answer

\[ \boxed{3.3 \text{ books}} \]

Identify the asymptotes. Give your answers in exact form. Do not round. a(x) = (x^3 + 3x^2 + 5x - 3) / (x^2 - 3) The expression (x^3 + 3x^2 + 5x - 3) / (x^2 - 3) is in lowest terms, and the denominator is zero at x = -sqrt(3) and x = sqrt(3) Thus, a has vertical asymptotes of x = -sqrt(3) and x = sqrt(3). The degree of the numerator is exactly one greater than the degree of the denominator. Therefore, a has no horizontal asymptote, but does have a slant asymptote.
