Answer:
x = 6
y = 2
Step-by-step explanation:
Me after hearing someone cough on my $8 round trip flight to Italy.
2) 5.625 mg will be left
Explanation:
1) Half-life = 17.5 days
initial amount of Arsenic-74 = 90 mg
To get the equation, we will use the equation of half-life:
2) we need to find the remaining amount of Arsenic-74 after 70 days
t = 70
So after 70 days, 5.625 mg will be left
Answer: using A= bh/2 THe height is 9.23
Step-by-step explanation: First, with the Right Angle at the bottom, usr the sides to compute the area: 12*5=60
THen Imagine the side=13 as the base, so you have b=13 for the formula
use the formula A= bh/2
60 = 13h/2 ==> 2(60) =13h --> 120/13 = h
h = 9.23
P(A|B)<span>P(A intersect B) = 0.2 = P( B intersect A)
</span>A) P(A intersect B) = <span>P(A|B)*P(B)
Replacing the known vallues:
0.2=</span><span>P(A|B)*0.5
Solving for </span><span>P(A|B):
0.2/0.5=</span><span>P(A|B)*0.5/0.5
0.4=</span><span>P(A|B)
</span><span>P(A|B)=0.4
</span>
B) P(B intersect A) = P(B|A)*P(A)
Replacing the known vallues:
0.2=P(B|A)*0.6
Solving for P(B|A):
0.2/0.6=P(B|A)*0.6/0.6
2/6=P(B|A)
1/3=P(B|A)
P(B|A)=1/3
