What is the equation of the line

kupik [55]

Answer:

y=-x+3.

Step-by-step explanation:

The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.

Ainat [17]

Answer:

The test statistic Z = 3.125

Step-by-step explanation:

Given Population proportion P = 0.25

Given sample size 'n' = 696

Sample proportion 'p⁻' = 0.30

Test statistic

$Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.30-0.25}{\sqrt{\frac{0.25 X 0.75}{696} } } = 3.125$

Final answer:-

The test statistic Z = 3.125
