Grasshoppers are distributed in a large field according to a poisson distribution with a parameter α = 2 per square yard. how large should the radius, r, of a circular sampling region be taken so that the proability of finding at least one in the regions is equal to .99?

Iam thinking the answer is a.) knew

How much is 32 out of 40 written as a percentage? convert fraction (ratio) 32 / 40 answer:   80%

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
