Answer + Step-by-step explanation:
<u>the conditional statement</u> :
For two positive integers n and m,
nm = 4 ⇒ (n = 1 or m = 1) or (n=m= 2)
<u>the contrapositive</u>:
(n ≠ 1 and m ≠ 1) and (n ≠ 2 or m ≠ 2) ⇒ nm ≠ 4
<u>Prove the conditional by proving the contrapositive</u> :
Suppose
m ≠ 1
and m ≠ 2
and n ≠ 1
⇒ nm ≠ 1 × n and nm ≠ 2 × n and n ≠ 1
⇒ nm ≠ 4 (because 4 = 4 × 1 or 4 = 2 × 2)
<u>Conclusion</u>:
The contrapositive is true then conditional is true.
Multiplying the two functions together using the Distributive Property, we get (2x²+x-3)*(x-1)=2x³+x²-3x-2x²-x+3= 2x³-x²-4x+3. In addition, since any value x can be plugged into 2x³-x²-4x+3, A is your answer!
Answer:
(C) The probability of buying bread and cheese is 0.12
Step-by-step explanation:
P(Event A) = 0.6
P(Event B) = 0.2
If Event A and Event B are independent,
Then P(Event A and Event B) = 0.6 x 0.2 = 0.12
Answer:
The y could be 9 and the b could be 9 so it would be 9+9 = 18
Step-by-step explanation:
9+9 = 18
