Answer:
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

Answer:
0.6
Step-by-step explanation:
the reason is because there are 5 different colors of marbles in the bag. it specifically says that each color has the same number of marbles for each color. so that would mean that there is 20% of each color of marble from the bag. its asking for three of the 5 colors. which means you would have a 60% chance of getting one of the colored marbles. which is were i got .6 from
Answer:
option d is a correct answer.....
Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.
Answer:
Savannah's annual salary is $ 78260 .
Step-by-step explanation:
As given
Savannah Bryan is career coach.
Her biweekly salary is $3010.
Thus
Here
