Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
We know that A. ∠ADE 
∠ABE because those are the only angles involved with 
.
22/36 simplified is 11/18. I hope this helps. Tell me if you need an explanation! : )
Answer:
Length of crab in x years = x + 2
Step-by-step explanation:
Since the crab grows 1 inch per year, and it would grow:
1 inch in the 1st year
2 inches in the 2nd year
3 inches in the 3rd year
4 inches in the 4th year
.
.
.
And so on.
However, in order to find the total length, you need to remember that the crab is originally 2-inches long. So the total length after x years would be the number of inches it grew over the years (x) + the length before the growth (2).
Thus, Length of crab in x years = x + 2
