A negative number is 42 less than it’s square.

Mathematics
1 answer:
marissa [1.9K]3 years ago
4 0

Answer:

Let x = the number

A negative number is 42 less than its square ⇒

x = x2 - 42

x2 - x - 42 = 0

(x - 7)(x + 6) = 0

x = 7 or -6

But since it is given that x is negative, the final answer is x = -6.

What's bigger 80% or 1/8?
Kobotan [32]
An easy way to solve this is to convert 1/8 into a percentage then see from that point.

To turn 1/8 into a percentage, you must first get the decimal form of the fraction. In this case, 1/8 as a decimal is 0.125.

Now that we have the decimal form, we can divide the decimal over 100 (common numerical number to use when dividing) to get the percentage, which should be 12.5%.

Now, our new question is 'what's bigger, 80% or 12.5%?'

The answer is 80%, since it is larger than 12.5%.

Suppose James randomly draws a card from a standard deck of 52 cards. He then places it back into the deck and draws a second ca
qwelly [4]

Answer:

1.92%

Step-by-step explanation:

The probability for first case, picking a queen out of deck, will be:

\frac{4}{52}

as there will be 4 queens in a deck, one of each suit.

For the second pick, the probability of picking a diamond card, will be:

\frac{13}{52}

here the total will remain 52 as he has replaced the first card and not kept it aside and there will be 13 cards in diamond suit (including the three face cards).

Thus the net probability for both cases will be:

P = \frac{4}{52}  * \frac{13}{52}\\ P = \frac{1}{52}\\ P = 0.01923\\P = 1.923\%\\\\P = 1.92\%

Thus total probability for the combined two cases will be 1.92%
