A product is the result of multiplication.
A quotient is the result of division.
So you're trying to find the quotient of a number (x) and 5 that equals 8.
Try plugging in the answers.
x/5=8
A. x=4
4/5=8 (Incorrect, 4 divided by 5 is 0.8)
B. x=8
8/5=8 (Incorrect, 8 divided by 5 is 1.6)
C. x=40
40/5=8 (Correct, 40 divided by 5 is 8)
D. x=80
80/5=8 (Incorrect, 80 divided by 5 is 16)
So your answer is C. 40
The quotient of 40 and 5 is 8.
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
Answer:
101
Step-by-step explanation:
To figure this out, you would do 167 - 66 = 101
101 + 66 = 167
That's answer exactly is -5
Answer:
If something is guaranteed, it has a probability of 100%, or 1.
Step-by-step explanation:
A standard deck has 52 cards. Of these, half are red cards (diamonds and hearts) and half are black cards (clovers and spades)
Half of the deck is 26 cards (52 ÷ 2 = 26), so you have 26 red and 26 black cards.
What this means in our context is, if we draw 27 cards, even if we drew all 26 black cards, we would still have 1 red card.
So the probability is 100%, or 1, of drawing a red card when we pick 27 cards from a deck, no matter how it's shuffled
