Answer:
1. P(C AND D) = 0.3
2. (C.) C and D are not mutually exclusive because P(C AND D) ≠ 0
3. (A.) The events are not independent because P(C | D) ≠ P(C)
4.P(D | C) = 0.5
Step-by-step explanation:
• Let P(C) = 0.4
• Let P(D) = 0.5
• Let P(C | D) = 0.6
1.) Find P(C AND D).
2.) Events can be mutually exclusive meaning the both event cannot happen at the same time. So, P(A and B) = 0
3.) Events can be "Independent", meaning each event is not affected by any other events.
4.) Find P(D | C)
8 rotations. first must convert 50 ft into inches. 50x12=600 in. If you know the distance and the length of rotation, divide the length (600) by the length of each rotation (75) and you get 8
Answer:
a). line h is perpendicular to line g
Step-by-step explanation:
In these cases, always make a litle scetch, and just plot what is given.
You can immediately see the answer, which is answer a).
lf h is parallel to f and line f is perpendicular to line g,
then line h is perpendicular to line g.
Answer:
true for all x
Step-by-step explanation:
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
true for all x
