Nathan has an infection and he needs to be treated with penicillin
But there’s a 75% probability of him being allergic to penicillin
And to test if the skin reacts to penicillin, the test is 98% accuracy
So even if he has the allergy the test is only 98% accurate of identifying the allergy
Therefore we are asked to find the probability of both these events happening
Event 1 and event 2 both should happen then. When the ‘and’ function is used in probabilities then the probabilities of both events happening should be multiplied
Therefore probability that Nathan has the allergy and test predicts it is
= 75% x 98% = 0.735
The answer is D. 0.735
Answer:
38 degrees
Step-by-step explanation:
Angle ABE is 90 degrees, and angle FBE is 52 degrees. 90-52 is 38.
Answer:
should be c
Step-by-step explanation:
when you count the boxes (units) you get 6 so segment AB should be 6 units long
Answer:
19,600
Step-by-step explanation:
0-49=50 numbers
n=50
r=3
C(n,r)=n!/(r!(n-r)!)
=50!/(47!)(3!)
C(n,r)=C(50,3)
=50!/(3!(50−3)!)
= 19600
It wouldn't be able to be because since all of the the numbers that could fit is probably going to be a decimal. Let's say we find 4 consecutive numbers of 32.
Equation:
x+(x+1)+(x+2)+(x+3)=32
4x+6=32
-6 -6
4x=26
x=6.5 1. 6.5, 7.5, 8.5, 9.5
As you can see, the consecutive number is going to be a decimal.
