About 80% of unvaccinated children who are exposed to whooping cough will develop an infection, as opposed to 5% of vaccinated children.
(a) what is the distribution of the number of new infections among the 17 vaccinated children? what is the mean number of new infections?
(b) what is the distribution of the number of new infections among the 3 unvaccinated children. what the the mean?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
