Answer:
The probability is 12.66%.
This is a low probability, so it is unlikely for such a combined sample to test positive.
Step-by-step explanation:
If the probability of being infected is 0.005, the probability of not being infected is 0.995.
Then, to find the probability of at least one of the 27 people being infected P(A), we can find the complementary case: all people are not infected: P(A').


Then we can find P(A) using:



This is a low probability, so it is unlikely for such a combined sample to test positive.
Answer:
Θ ≈ 58°
Step-by-step explanation:
using the Cosine Rule in the triangle
cosΘ =
=
=
=
, then
Θ =
(
) ≈ 58° ( to the nearest degree )
Answer:Yes it does
Step-by-step explanation:because it goes on the right path
Answer:
Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
Answer:
57
Step-by-step explanation:
I prefer the equation in this format

substitute -4 for m and 6 for n

square the 6 then multiply by 2

solve inside the absolute value then multiply by 3


divide by 4
