There is a 50% chance that the Fed will cut interest rates tomorrow. On any given day, there is a 67% chance the DJIA will incre
Amanda [17]

Answer:

3) 0.72

Step-by-step explanation:

The probability that tomorrow the Fed will cut interest rates (P(F)) OR the DJIA will go up (P(D)), is the sum of each event's individual probability minus their joint probability (Fed cutting interest rates AND the DJIA will going up, P(FD))

P(F+D) = P(F) +P(D) - P(FD)\\P(F+D) = 0.5 + 0.67 - (0.5*0.9)\\P(F+D) = 0.72

The probability that tomorrow the Fed will cut interest rates or the DJIA will go up is 0.72.

Factor x³ + x² + x + 1 by grouping. What is the resulting expression?
vladimir1956 [14]
<h3>Answer:  (x² + 1)(x + 1)</h3>

Work Shown:

x³ + x² + x + 1

(x³ + x²) + (x + 1)

x²(x+1) + 1(x + 1)

(x² + 1)(x + 1)

The basic outline is to pair up the terms into two groups. We factor each group separately, and then factor out the overall GCF (x+1). You can use the FOIL rule to verify the answer.
