Question

When a group of people were tested for a rare disease, 99.6 percent of them
were found not to have the disease If the 10 people did have the disease, how
many people were tested? *​

Answer 1

Answer:

2600 were tested

99.6% of 2590 = - 10 + 10  = 2600 people.

99.6% of 2600 = 2589.6

Step-by-step explanation:

10 = positive = inverse of 99.6 = 0.4

0.4 x 1000 = 400

So we need an odd number ie) 3,000 minus 400 to make 10 extra when inverse is missing. = 3000 - 400 = 2600

99.6% of 2600 = 2589.6

Is the lowest number.
