Answer:
Step-by-step explanation:
um i think its c but im not fully sure
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
He did this then that plus to this and that =334.2
Answer:
I think there are 23 students in the art class.
Step-by-step explanation:
You first subtract 9 from 101. Then, you divide by four to get 23.
I) 156 degrees
The exterior angle is 180-156
=24
The number of sides=
The number of sides= 15 sides
ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=
= 20 sides
