Answer:
29.411 % of the result is true.
Step-by-step explanation:
This test's sensitivity is low.
Suppose we have 5 drug users and 85% of the test is accurate meaning that 5* 0.85= 4.25 people are drug users which is true.
But if work for the non users than 5% people being drug users means 95 people are non drug users out of the hundred.
And 85 % accuracy would give 95* 0.85= 80.75 which is very high.
And out of the 80.75 * 15%= 12.11 only 12 are positive .
The results give us 5 out of 17 true possibilities
or 5/17 *100= 29.411 % of the result is true.
The simple and easiest way to find it is that you add all the numbers of that value i.e.: 1485=1+4+8+5 it will give u a number which will tell u if it is divisible by what number i mean that: 1+4+8+5=18 so 18 is divisible by 2, 3, 6, and 9
Answer - to solve for the equivalent equation of r you would need to use the formula r=c/pi2.
That would be 8. first parenthesis, then multiply, then subtract.
The answer to this problem is x - 17.
