Answer:
Step-by-step explanation:
<u>Let's factor the trinomial:</u>
- x² + 14x + 40 =
- x² + 4x + 10x + 40 =
- x(x + 4) + 10(x + 4) =
- (x + 4)(x + 10)
x + 4 is between the answer options
Correct option is D.
Answer:
Not a solution.
Step-by-step explanation:
Step 1: Write inequality

Step 2: Solve for <em>r</em>
- Subtract 4 on both sides: r > 4
Step 3: Determine
r = 2
2 > 4 = FALSE

Answer:
(a) 0.1666 (b) 0.5 (c) 0.166
Step-by-step explanation:
A die is rolled so sample space = { 1,2,3,4,5,6 } so n=6
(a) the number showing is four so expected value is only 4 so favorable outcomes {4}
so probability 
(b) the number showing an even number
so favorable outcomes= { 2,4 ,6 }
so probability 
(c) the number showing greater than 5 that is only {6}
so probability
