In a recent year, potentially dangerous commercial aircraft incidents (e. g., near collisions) averaged 1.2 per 100,000 flying hours. Let X be the number of incidents in a 100,000-hour period. (a) Justify the use of the Poisson model. Each collision is dependent on the occurrence of another. Collisions are routine systematic occurrences. Near collisions are random and independent events. (b) What is the probability of at least one incident

b) the dogs need to shift their focus to human scent.

step-by-step explanation:

20-2= what

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
