Answer:

The equation of line is $(y-2) = \frac{4}{3} (x -5)$

Step-by-step explanation:

Here, the two point line are given as is A(5,2) and B(-1,-6)

The slope of the line AB = $m = \frac{y_2 - y_1}{x_2 - x_1}$

$= \frac{-6- 2}{-1 -5} = \frac{-8}{-6} = \frac{4}{3}$

⇒ the slope of AB is m = (4/3)

By POINT SLOPE FORMULA:

The equation of a line with slope m and a point (x0, y0) is given as

(y-y0)= m (x-x0)

⇒ The equation of line with point (5,2) is:

$(y-2) = \frac{4}{3} (x -5)$

Hence, the equation of line is $(y-2) = \frac{4}{3} (x -5)$

The mean of a set of credit scores is and . Which credit score is within a z-score of 3.3?

sveta [45]

Answer:

720

Step-by-step explanation:

The mean of a set of credit scores is u=690 and o=14.

mean = 690 and standard deviation SD = 14

We use z- score formula

z= 3.3 given

Plug in the values and find out x

Multiply 14 on both sides

46.2 = x- 690

Now add 690 on both sides

x= 736.2

Credit score is 720 that comes under 736.2

(20 points) A random sample of =1200 n = 1200 registered voters and found that 620 would vote for the Republican candidate in a

LenaWriter [7]

Answer:

The test statistic is Z = 1.157

Step-by-step explanation:

Given that:

The sample size n = 1200

The sample proportion of those that will vote for the Republican candidate is represented by $\hat p = \dfrac{x}{n}$

$\hat p = \dfrac{620}{1200}$

$\hat p =0.5167$

The null and the alternative hypothesis can be computed as:

$H_o: P=0.50 \\ \\ H_a :P>0.50$

The formula for the one-sample Z-test for the population proportion can be expressed as:

$Z = \dfrac{\hat p - P_o}{\sqrt{\dfrac{P_o(1-P_o)}{n}}}$

$Z = \dfrac{0.5167 - 0.5}{\sqrt{\dfrac{0.5(1-0.5)}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{\dfrac{0.5(0.5)}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{\dfrac{0.25}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{2.08333333\times10^{-4}}}$

Z = 1.157
