Answer:
Two figures that have the same shape are said to be similar. When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles below are similar, compare their corresponding sides.
The number of people who voted follows a binomial distribution with probability of having voted

and

subjects, which means the approximating normal distribution should have mean

and standard deviation

.
With the continuity correction, you have
11c-4c = 7c
5c+2c= 7c
3c+7c= 10c
11c-4c= 5c+2c =A
V=u + at
V - u = at divide both sides by
t
(V-u)/t =a
a = (v - u) /t
