Option C is right answer
Step-by-step explanation:
Given that Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan had a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate.
Probability that Nathan is allergic to pennicillin and the test predicts it
=Prob (Nathan is allergic)*P(test predicts it correct)
= 0.75(0.98)
=0.245

plato
Step-by-step explanation:
Each term is 9 more than the previous term....the common difference, d = 9
an = a1 + 9(n-1) where a1 is the first term = 4
this reduces to: an = 4 + 9n-9
an = 9n - 5
the 30th term is then a30 = 9(30) - 5 = 265
