A line goes throught the points (0,-9) and (-9,-72)<br><br>what is the slope of the line?
Vladimir [108]

To find the slope(m) of the line, you use the slope formula:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

And you plug in the points into the equation.


m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m = \frac{-72-(-9)}{-9-0}

m = \frac{-72+9}{-9-0}

m = \frac{-63}{-9}

m = 7

It is known that 60 percent of all registered voters in the 42nd Congressional District are Republicans. Three registered voters
Gelneren [198K]

Answer:

0.11

Step-by-step explanation:

Let x be a random variable representing the number of registered voters in the congressional district. This is a binomial distribution since the outcomes are two ways. It is either a randomly selected registered voter is a conservative or not. The success would be that a randomly selected voter is a conservative. The probability of success, p = 60/100 = 0.6

The probability of failure, q would be 1 - p = 1 - 0.6 = 0.4

Given n = 10, we want to determine P(x = 4)

From the binomial distribution calculator,

P(x = 4) = 0.11
