Answer:
2
Step-by-step explanation:
Given the circle: 
To determine the length of the radius, we complete the square.
Step 1: Subtract 4 from both sides
Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides
Step 3: Factorize the Left Hand side and simplify the Right Hand side.
Comparing with the standard form of the equation of a circle
r=2
Therefore, the radius of the circle is 2.
answer
45
step-by-step explanation
total = day1 + day2 + remaining
total = 70
day1 = 10
day2 = 15
plug in values
70 = 10 + 15 + remaining
remaining = 70 - 10 - 15
remaining = 45 cans
Answer:
5x-20
Step-by-step explanation:
multiply and distribute the 5
Answer:
Step-by-step explanation:
The probability of asking for the cherries flambe and dying, P(A) = 0.5 × 0.6 = 0.3
The probability of asking for the chocolate mousse and dying, P(A) = 0.4 × 0.9 = 0.36
The probability of skipping dessert altogether = 0.1 × 0 = 0
The probability that the rich uncle dies, P(D) is
P(D) = 0.3 + 0.36 + 0 = 0.66
To determine the prime suspect, we would apply the concept of conditional probability. It is the probability of an event, A occurring given that event B has occurred. We would compare probabilities of the events A and B occurring given that event D also occurred
Therefore,
P(A|D) = 0.3/0.66 = 0.45
P(B|D) = 0.36/0.66 = 0.55
Therefore, the prime suspect is Margo because his probability is higher
