In one town, 47% of all voters are Democrats. If three

34kurt

Answer:

The probability that the all three votes are Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

$P(X=r) = n_{C_{r} } p^{r} q^{n-r}$

The probability that the all three votes are Democrats

P(X=3) = 0.1038

n=3 and r=3

$P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}$

$P(X=3) = 1 (0.47)^{3}$

P(X=3) = 0.1038

Final answer:-

The probability that the all three votes are Democrats

P(X=3) = 0.1038

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7);m=-3/2

love history [14]

For this case we have that the point-slope equation of a line is given by:

$(y-y_ {0}) = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point

We have as data that:

$(x_ {0}, y_ {0}): (- 2, -7)\\m = - \frac {3} {2}$

We replace:

$(y - (- 7)) = - \frac {3} {2} (x - (- 2))\\(y + 7) = - \frac {3} {2} (x + 2)$

Answer: $(y + 7) = - \frac {3} {2} (x + 2)$
