The formula is y2 - y1/x2 - x1.  The answer would be 3/4 once simplified.

You use the slope formula:

m = y₂-y₁ / x₂-x₁

And you plug in the points into the formula.

m = -9 - (-6) / -1 - 3

m = -9 + 6 / -1 - 3

m = -3 / -4

m = 3/4

The weight of an organ in adult males has a​ bell-shaped distribution with a mean of 325 grams and a standard deviation of 25 gr
vampirchik [111]

Answer:

(a) between 300 grams and 350 grams  (b) 95%  (c) 5%  (d) 83.85%

Step-by-step explanation:

We have that \mu = 325 grams and \sigma = 25 grams. Let's compute the following figures to use the empirical rule

\mu + \sigma  = 325 + 25    = 350  

\mu + 2\sigma = 325 + 2(25) = 375  

\mu + 3\sigma = 325 + 3(25) = 400  

\mu - \sigma  = 325 - 25    = 300  

\mu - 2\sigma = 325 - 2(25) = 275  

\mu - 3\sigma = 325 - 3(25) = 250  

using the image below that was made it with help of the empirical rule we find the next figures

(a) About 68% of organs will be between 300 grams and 350 grams

(b) 95% of organs weights between 275 grams and 375 grams

(c) 5% of organs weights less than 275 grams or more than 375 grams

(d) 83.85% of organs weights between 300 grams and 400 grams
