Acoach needs both small and large cones to set up an obstacle course. he knows there are fewer than 30 cones in the storage room. he needs at least a dozen large cones. let x represent the number of small cones and y represent the number of large cones.
which inequalities model the situation?
choose exactly three answers that are correct.
(points : 1)
x + y < 30
x + y ≤ 30
y > 12
y ≥ 12
x > 0
x ≥ 0

What is the x-intercept and y-intercept of the equation 2x+1. 2o

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?

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
