A survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 9 adults are randomly selected, find the probability that at least 8 of them need correction for their eyesight. Is 8 a significantly high number of adults requiring eyesight correction?

yes

Step-by-step explanation:

well if it's only 9 men than that is a high percentage that need correction, how every 8 to the rest of men, lets say theirs 3 billion men, that is a low percentage that needs correction. give a bit more context next time, like more men or women.

the monthly balance will be $75,000

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
