A^2+b^2=c^2 so 4(4) +3(3) is 16+9= 25 and the square root of that is 5.
Answer:
18/42
Step-by-step explanation:
Find the common factor of the denominators i.e the common factor of 7 and 42. The answer is 6. Multiply the fraction with the smallest denominator by the common factor (3/7 ×6/6) answer is 18/42

Answer:
q=12.
Step-by-step explanation:
1/3(q+3)=5 can be translated to (q+3)/3=5.
Multiply each side by 3 to get q+3=15.
Subtract 3 from each side to get q=12.
Can you explain what you mean by "Explain why 1/3 is a fraction?"
a. By definition of conditional probability,
P(C | D) = P(C and D) / P(D) ==> P(C and D) = 0.3
b. C and D are mutually exclusive if P(C and D) = 0, but this is clearly not the case, so no.
c. C and D are independent if P(C and D) = P(C) P(D). But P(C) P(D) = 0.2 ≠ 0.3, so no.
d. Using the inclusion/exclusion principle, we have
P(C or D) = P(C) + P(D) - P(C and D) ==> P(C or D) = 0.6
e. Using the definition of conditional probability again, we have
P(D | C) = P(C and D) / P(C) ==> P(D | C) = 0.75
