By definition of conditional probability,
P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5
c. the number of persons allegric to penicillin
8x - 4y = 8
-4y = -8x + 8
y = -8x/-4 + 8/-4
y = 2x - 2, comparing to y = mx + c, slope m = 2
Slope = 2.
Answer:
the answer is 2/6 im not sure but i hope its help
The distance traveled by the Salmon is proportional to the duration spent
swimming.
A table of the distance traveled by the Atlantic Salmon is presented as follows;

Reasons:
The given parameter are;
The steady rate at which Atlantic Salmon swims = 2 miles in 3 minutes
Distance the Salmon swims, d ∝ Time taken, t
Therefore;
d = s·t
Where;
s = The constant of proportionality = The speed
Which gives;

The speed with which the Atlantic Salmon swims per minute is therefore;

The distance travelled, <em>d</em>, is given as follows;

A table showing the distance travelled by the fish with time is presented as follows;
