Answer:
x < -2; x > 5
Step-by-step explanation:
5x + 7 < - 3 3x - 4 > 11
-7 -7 +4 +4
5x < - 10 3x > 15
/ 5 /5 /3 /3
x < -2 x > 5
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.
The answer would be D because you are subtracting a positive 17 from a positive 88
