Help on this I got this wrong
1 answer:
Check the picture below.
recall, AB = AC, and AR is an angle bisector to the vertex A, so A gets split into two equal angles, so those angles are twins.
now, the segment AR is part of triangle ABR and is also part of the triange ACR, however, is being shared by both, and therefore, is the same length on each triangle.
so you have a Side, in green, an Angle, from the twins, and another Side, being shared by both, Side Angle Side, SAS.

Answer:
Probability that exactly 5 of them favor the building of the health center is 0.0408.
Step-by-step explanation:
We are given that in a recent survey, 60% of the community favored building a health center in their neighborhood.
Also, 14 citizens are chosen.
The above situation can be represented through Binomial distribution;
where, n = number of trials (samples) taken = 14 citizens
r = number of success = exactly 5
p = probability of success which in our question is % of the community
favored building a health center in their neighborhood, i.e; 60%
<em>LET X = Number of citizens who favored building of the health center.</em>
So, it means X ~
Now, Probability that exactly 5 of them favor the building of the health center is given by = P(X = 5)
P(X = 5) =
=
= 0.0408
Therefore, Probability that exactly 5 of them favor the building of the health center is 0.0408.
