Answer:
136
Step-by-step explanation:
The attached chart shows the result of using the numbers in the problem statement to calculate the percentage of the population in each category.
95% accuracy on infected individuals is assumed to mean that 95% of the 2% who are infected return a positive test result. The other 5% return a negative test result.
Similarly, 90% accuracy on uninfected individuals is assumed to mean that 90% of the 98% who are not infected will return a negative test result, and the remaining 10% of those 98% will return a (false) positive test result.
Then of the 11.7% who return a positive test result, only 1.9% are actually infected. This fraction is a/b = 19/117, so ...
a + b = 19 + 117 = 136

<em>Additional comment</em>
When forming ratios of percentages, one must be very clear about the base of the percentage. Above, the base for every percentage is the entire population of mathletes. The fraction 19/117 is the fraction of those who tested positive that are actually infected (about 16.2% of positives).
First, convert into a decimal:
1/10,000,000 = 0.00000001
Next, convert to "the number with a power of 10 using a negative exponent. Move the decimal point to the first <em>number that is not 0</em> (sorry, there is a term for it, but i can't remember it right now, but it is not important to solving the answer)
0.000001 = 1 * 10^-7
1 * 10^-7 is your answer

Answer:
It holds approximately 4 litres in accent
Step-by-step explanation:
In terms, 1 litre = 1000 cubic centimetres.
-----------------------------------------
Therefore, to find How many liters of oil the container hold. Divide 4000 cubic centimeters by 1000.
⟼ 4000 ÷ 1000
⟼ 4
Therefore, 4000 cubic centimeters volume of oil holds 4L of oil
