I would go with b. the mean age of all students in her middle school is likely to be close to 11.6.
Because she used a simple random sample, the outcome is likely to be an accurate representation of the entire middle school. It might not be exact, but likely close to 11.6.

Write a quadratic equation whose roots are -4 and one and who's leading coefficient is five

Alex

Step-by-step explanation:

- 4 and 1 are roots.

Therefore, (x + 4) & (x - 1) are factors and 5 is leading coefficient.

Therefore, required quadratic equation is:

$5 (x + 4) (x - 1) \\ = 5( {x}^{2} - x + 4x - 4) \\ = 5( {x}^{2} + 3x - 4) \\ = 5 {x}^{2} + 15x - 20$
