-12-18x+8=69
-4-18x=69
-4+4 -18x=69+4
-18x=73
-18x/-18 =73/-18

Suppose that the number of gallons of milk sold per day at a local supermarket are normally distributed with mean and standard d
miv72 [106K]

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

P(304

The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
cricket20 [7]
  To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag) 
5/25 x 100% (because you're trying to find probability of red) 
= 20% 

2) 5 + 8 = 13 (# of red AND blue) 
13/25 x 100% (divide out of the total) 
=52% 

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green) 
0.2 x 0.48 x 100% 
= 9.6% 

4) 10 + 12 + 28 = 50 (to find total number of trials) 
28/50 x 100% 
= 56% 

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner) 
= 35</span><span>Its B 20%
