Suppose that the number of gallons of milk sold per day at a local supermarket are normally distributed with mean and standard d
1 answer:
Answer:
<em>The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%</em>
Step-by-step explanation:
<u>Normal Distribution</u>
The graph of the Normal Distribution is also called the Bell Curve because of its particular shape. It occurs naturally in many real situations where a random variable needs to be modeled according to experimental results.
To evaluate the probability of a Normal Distribution, we need some kind of digital means because the formula cannot be computed directly in a formula. We'll use the MS Excel's specialized formula NORMDIST for the first value of x=304:
NORMDIST( 304 , 319.9 , 26.4 , true ) = 0.2735
Now for x=305:
NORMDIST( 305 , 319.9 , 26.4 , true ) = 0.2862
Both values are now subtracted to get the required probability
The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%

Step 1) Draw a dashed line through the points (0,6) and (4,7). These two points are on the line y = (1/4)x+6. To find those points, you plug in x = 0 to get y = 6. Similarly, plug in x = 4 to get y = 7. The dashed line indicates that none of the points on this line are part of the solution set.
Step 2) Draw a dashed line through (0,-1) and (1,1). These two points are on the line y = 2x-1. They are found in a similar fashion as done in step 1.
Step 3) Shade the region that is above both dashed lines. We shade above because of the "greater than" sign. This is shown in the attached image I am providing below. The red shaded region represents all of the possible points that are the solution set. Once again, any point on the dashed line is not in the solution set.

We are asked to find the slope of the line that is parallel to the line .
- Parallel lines have the same slope.
So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.
- The slope is the coefficient of x.
So the slope is
.
Can you guess the slope of the line that is parallel to the first line?
That's right! The slope is...
Hope it helps you out! :D
