Help! i just need the 3rds question, my brain is fried
Sergeeva-Olga [200]

Answer:

0.00665

0.006951

Step-by-step explanation:

If the first child is born with the affliction, there's a 0.05 probability that the second child will be born with the affliction.  Which means there's a 0.95 probability that they won't.

The probability that the first child is born with the affliction but not the second is therefore:

P = 0.007 × 0.95

P = 0.00665

There's a 0.007 probability that the first child will be born with the affliction, which means there's a 0.993 probability that they won't.  If the first child isn't born with the affliction, then the probability the second child will have it is 0.007.

So the probability that the first child is not born with the affliction and the second child is would be:

P = 0.993 × 0.007

P = 0.006951

Explain to me in words how you would find the slope of this line
vekshin1

Answer:

Step-by-step explanation:

go from one point to the other. From the left point to the right point you are running across (to the right) three times. Then you are ¨rising¨ (going down) once. going to the right is positive. If you are going down its negative. Vise versa. The formula is Rise/Run. your answer would be -1/3. the one is negative because it went down.Then divide it and you have -0.333. I hope I helped!
