Answer:
<h2>d=7.2</h2>
Step-by-step explanation:
We can use the Pythagoras theorem to solve for the answer.
step one:
given that the points are located at (x1,y1),(x2,y2) =(3, -6) and (-3,2)
step two:
substituting into the formula we have
To the nearest tenth we have
d=7.2
Answer: 8/145
Step-by-step explanation: Rewriting the table
Positive and Negative stand for the result of the test
Yes and No stand for having the disease
Positive | Negative | Total
<u>Yes </u><u> | 137 | 8 | 145</u>
<u>No </u><u> | 16 | 139 | 155</u>
<u>Total</u><u> | 153 | 147 | 300</u>
<u />
probability of getting someone who tests negative, given that he or she had the disease.
P(Negative | Yes) = <u>P(Negative ∩ Yes)</u> = <u> 8 </u>
P(Yes) 145

There you go. The file's down there.
