Answer:

A) 0.29; C) 0.36; A) are

Step-by-step explanation:

There are a total of 128+162 = 290 people that are over 25 years old.  Out of these, there are 84 people with a hemoglobin level above 11; this is a probability of 84/290 = 0.29.

There are 154 people with a hemoglobin level over 11 out of 429 people total; 154/429 = 0.36.

In order for two events to be independent,

P(A∩B) = P(A)·P(B)

The probability that someone is over 25 and has a hemoglobin level above 11 was 0.29.

The probability that someone is over 25 is 290/429; the probability that someone has a hemoglobin level above 11 is 154/429.  This makes

P(A)·P(B) = (290/429)·(154/429) = 0.24

The probabilities are not equal, so the events are not independent; this means they <em>are</em> dependent.

Write the equation of the line that passes through the points (-9, -8) and (–6,6).
sveta [45]

Answer:

Slope - intercept form    y = \frac{14}{3} x  + 34

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given points are ( -9 ,-8 ) and (-6,6)

slope of given two points

    m = \frac{y_{2} -y_{1} }{x_{2}-x_{1}  } = \frac{6-(-8)}{-6-(-9)} = \frac{14}{3}

The equation of the straight line passing through the points and having slope

          y - y_{1} = m ( x - x_{1} )

        y - (-8) = \frac{14}{3}  ( x - (-9) )

          3 y + 2 4 = 14 x + 126

           3 y = 14 x + 126 - 24

          3 y = 14 x + 102

            y = \frac{14}{3} + \frac{102}{3}

           y = \frac{14}{3} x  + 34

Slope - intercept form  y= mx +C

Slope - intercept form    y = \frac{14}{3} x  + 34

All you have to do is figure out the rest of the decimal places.  I couldn't go any farther. Good luck!
