Answer:
Step-by-step explanation:
Parallel lines have the same slope. The slope of the given line is 3. The easy way to do this, the one that uses our logical brains as opposed to our mathematical brain, tells us that since there is only one choice that has a given slope of 3, that is the one that we want. The second choice down is the only one that has a slope of 3.
Mathematically,
and
and
so
y = 3x - 7 (the second choice)
Answer:
The supreme court should up hold DACA.
Step-by-step explanation:
I don't know much about the issue but that DACA is bacicly the way for immigrants to come to the US legally. it is unconstitutional in the US to not. let immigrants have a way to enter the US in in a legal way.
Y = 2x + 12
2(4) + 12 = 8 + 12 = 20
She spends $20
Answer:
Check Explanation
Step-by-step explanation:
a) Yes, the two events are mutually exclusive. The true meaning of mutually exclusive is that both A1 and A2 have no sample points in common and cannot both occur at the same time.
The only sure mathematical way to tell is from P(A1 n A2) = 0.
Note that this is different from when two events are independent. Two events are independent when the chances of one occurring does not depend on the chances of the other event occurring at all. Independent events can both occur at the same time. Mathematically, independent events are described as P(A1|A2) = P(A1) and P(A2|A1) = P(A2)
b) To solve for P(B)
We use the mathematical definition of the conditional statement
P(B|A1) = P(B n A1)/P(A1)
P(B n A1) = P(B|A1) × P(A1) = 0.2 × 0.4 = 0.08
P(B|A2) = P(B n A2)/P(A2)
P(B n A2) = P(B|A2) × P(A2) = 0.05 × 0.6 = 0.03
P(B) = P(B n A1) + P(B n A2) (especially because A1 and A2 are mutually exclusive)
P(B) = 0.08 + 0.03 = 0.11
Hope this helps!!
