A certain blood test accurately indicates the presence of a disease 87% of the time when the disease is actually present. The test indicates the presence of the disease 0.4% of the time when the disease is not present. If 2% of the population has the disease, what percentage of the total population will receive a false positive

0.392% of the total population will receive a false positive

Step-by-step explanation:

We have that:

2% of the population has the disease.

So 100-2 = 98% of the population does not have the disease.

For 0.4% of the people who do not have the disease, the test is positive.

What percentage of the total population will receive a false positive

0.4% of 98%. So

0.004*0.98 = 0.00392

0.392% of the total population will receive a false positive

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
