GCF is 3 because 3 times 3 is 9 and 3 times 7 is 21.

$slope = \frac{ - 8 - ( - 11)}{7 - 4} \\$

$slope = \frac{ - 8 + 11}{7 - 4} \\$

$slope = \frac{3}{3} \\$

Use a normal approximation to find the probability of the indicated number of voters. In this case assume that 150 eligible vote

alexdok [17]

The number of people who voted follows a binomial distribution with probability of having voted $p=0.22$ and $n=150$ subjects, which means the approximating normal distribution should have mean $np=33$ and standard deviation $\sqrt{np(1-p)}\approx5.07$ .

With the continuity correction, you have

$\mathbb P(X$
