Answer:
20.
$18.40.
Step-by-step explanation:
The mean number of people = (12+19+17+26+26)/5
= 100/5
= 20.
Karmin's original hourly rate = 480/30
= $16 per hour.
With a 15% rise it is 16 * 1.15
= $18.40 / hour.
Answer:
Step-by-step explanation:
p^2-8p-9
factor out the trinomial
(p-9)(p+1)
Therefore, she's incorrect. Because (p-1)(p+9)=p^2-p+9p-9=p^2+8p-9 and that's different from p^2-8p-9.
Answer:
In order to get this perfect square trinomial, the factored form will be (a - b)^2
Step-by-step explanation:
We know this because it follows the rule of perfect squares in which the ends are both squares and the middle term is -2 times each term.
