Step-by-step explanation:

$\int \bigg( - \frac{2}{7} {x}^{3} - 4 {x}^{4} - 2x \bigg)dx \\ \\ = - \frac{2}{7}\int {x}^{3}dx - 4 \int {x}^{4}dx - 2\int x dx \\ \\ = - \frac{2}{7} \times \frac{ {x}^{4} }{4} - 4 \times \frac{ {x}^{5} }{5} - 2 \times \frac{ {x}^{2} }{2} + c \\ \\ = - \frac{{x}^{4} }{14} - \frac{4}{5} {x}^{5} - {x}^{2} + c \\$

A daily mail is delivered to your house between 1:00 p.m. and 5:00 p.m. Assume delivery times follow the continuous uniform dist

german

Answer:

25% of deliveries

Step-by-step explanation:

This is a uniform distribution with parameters a = 1.00 and b =5.00. With these conditions, the following probability distribution functions can be applied:

$P(X \leq x)=\frac{x-a}{b-a}=\frac{x-1.00}{5.00-1.00}\\P(X \leq x) = \frac{x-1}{4}\\P(X \geq x) = 1- P(X \leq x) \\P(X \geq x)=1- \frac{x-1}{4}$
