Answer:
C.Yes, because the joint probability of P and M is equal to 0.
Step-by-step explanation:
If M and P are two sample spaces of their respective events, such that ( A ∩ B ) = Ø [phi or the empty set represented by ‘Ø’ contains no element]. Then the probability of either A or B happening will be written as follows:
P ( M ∪ P) = P (M) + P ( P ) ; where the symbol ‘∪’ represents union or the word ‘or’. So the probability of occurrence of either A or B when A and B are mutually exclusive events is equal to the probability of occurrence of A plus the probability of occurrence of B.
D = k + 20
j = 3k - 120
d = j
k + 20 = 3k - 120
20 + 120 = 3k - k
140 = 2k
140/2 = k
70 = k.....so Katie weighs 70 lbs
David and Johnathan each weigh 90 lbs
If you want to work out the force then F=MA, therefore 43*8.6=369.8 Newtons

a^2 - b^2 = (a + b)(a - b)
so
x^2 - 25
= x^2 - 5^2
= (x + 5)(x - 5)
Answer is B. (x + 5)(x - 5)
