Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721

Answer:
168 employees
Step-by-step explanation:
5:3
63 / 3 = 21
5*21=105
105+63=168
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
