Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive
We are given
P(A)=0.75 [ probability that Nathan is allergic ]
P(T|A)=0.98 [probability of testing positive given Nathan is allergic to Penicillin]
We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)
From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735
Answer:
I'm pretty sure it would be (5,6)
Step-by-step explanation:
Reflecting a point over the Y-axis would change the x-coordinate, but not the y-coordinate
Answer:
The Parenthesis tells you what operation to do first.
Step-by-step explanation:
Why? Because you have to get rid of the Parenthesis before getting rid of anything else in the problem.
Answer:
40
Step-by-step explanation:
a^2+b^2=c^2
therefore c^2-b^2=a^2
41x41=1681
9x9=81
1681-81=1600
Sqrt1600=40
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation of a line in the standard form:
Convert to the slope-intercept form:
<em>subtract 6x from both sides</em>
<em>divide both sides by 4</em>
