Step-by-step explanation:
Tangents to the circle from the same point are the same length. Then rn = 7, and nt = 10. This means mt = 10, so ...
st = sm +mt = 5 +10
sm = 15
Answer:
If I would have to have to make a choice I would put D.
Step-by-step explanation: Because if you look the intersected part is closer to 5 than 4 so you would put 4 5/6 for y and for x I would put -1 1/5 because it is closer to -1 than -2
Answer:
0.505 = 50.7% probability of a negative test.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
142 + 6 = 148 people tested positive. Of those, 142 had the disease and 6 did not.
7 + 145 = 152 people tested negative. Of those, 7 had the disease and 145 did not.
Find the probability of getting someone who tests negative, given that he or she did not have the disease.
This is the probability of a negative test.
152 negative tests out of 148 + 152 = 300
152/300 = 0.507
0.505 = 50.7% probability of a negative test.
