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:
Step-by-step explanation:
x = number of windows being washed
3x + 15 > = 50 (thats greater then or equal to)
3x > = 50 - 15
3x > = 35
x > = 35/3
x > = 11 2/3
so he would have to wash 12 windows to get the minimum amount.....any more window money would go to the additional accessories.
Answer:
The answer is letter A.
Step-by-step explanation:
The amount that each company charges per hour on the pool is known, however the amount of hours they will be working is not, and is needed to distinguish which company is cheaper. Therefore, the number of hours is substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).
I guess that u can use Pythagorean theorem!:(
