Step-by-step explanation:
a. P(mites OR ticks) = P(mites) + P(ticks) − P(mites AND ticks)
P(mites OR ticks) = 0.80 + 0.30 − 0.20
P(mites OR ticks) = 0.90
b. P(no ticks | mites) = P(no ticks AND mites) / P(mites)
P(no ticks | mites) = (0.80 − 0.20) / 0.80
P(no ticks | mites) = 0.75
c. If two events are independent, then P(A and B) = P(A) × P(B).
P(mites AND ticks) = 0.20
P(mites) × P(ticks) = 0.80 × 0.30 = 0.24
They are not independent.
Answer:
You can start by distributing the 3 to the m+4
(3m + 12)
Now you can add on the -5m and simplify
(3m+12-5m)
-2m+12
Answer:
1st question answer is A = πr^2 2nd question answer is A≈28.27ft²
Step-by-step explanation:
Answer:
Step-by-step explanation:
y+2/3 x=4
multiply by 3
3y+2x=12
or 2x=12-3y
so both represent the same equation of a line .
there are infinite points on the line.
infinite solutions.
