<span>To answer the question above first we need toclarify what the inequality is actually saying:
7 - 9x - (x + 12) </= 25 (simplify)
-5 - 10x </= 25 (add 5 to both sides)
-10x </= 30 (divide by -10 to get x)
x >/= -3 (don't forget to flip the signs when you divide by a negative number)
So this says x is greater than or equal to -3, so which of these statements is not a way to represent that?
I'd say it's the second one. x is greater than not less than.</span>
For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
