We are asked to solve for:
P (sand | positive)
So, we solve this by:
P (sand | positive) = P (sand) x P (positive for sand)
P (sand | positive) = 0.26 (0.75)
P (sand | positive) = 0.195
The probability is 0.195 or 19.5%.
Answer:
40%.
Step-by-step explanation:
We have been given that the owners of Expo Company John Smith and Susan Jones invested $240,000 and $160,000 into the business respectively. We are asked to find the percentage of business owned by Susan.
Let us figure out total money invested in business by adding the money invested by John Smith and Susan Jones.


Now we will find $160,000 is what percent of $400,000.



Therefore, Susan owns 40% of the business.
Answer:
12
Step-by-step explanation:
0.8 is equal to 80%
you need to figure out 80% of 15
100% = 15
10% = 1.5
(x8)
80% = 12
you would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>
