If f is a function whose domain includes all real numbers, the improper integral ∫∞−∞f(x)dx is defined to equal ∫0−∞f(x)dx∫∞0 f(x)dx provided both of those improper integrals converge. with that definition in mind, the improper integral ∫∞−∞x 31+x 4 dx will:

Fredrick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin

Solve the inequality and graph 6j - 7 < 5

Using pert, adam munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 21 months, and the project variance is 4. a) what is the probability that the project will be completed in 17 months? b) what is the probability that the project will be completed in 20 months? c) what is the probability that the project will be completed in 23 months? d) what is the probability that the project will be completed in 25 months? e) what is the due date that yields a 95% chance of completion?
