Answer: 4 years

Step-by-step explanation: Begin by writing the interest formula.

Interest = principal x rate x time

Filling in the formula, the interest is $252, the principal is $900, the rate is 7% or .075 and we don't know the time so we use the variable <em>t.</em>

252 = (900)(.07)(t)

On the right side of our equation, we multiply 900 times .07 to get 63 and we have 252 = 63t. Now to solve for <em>t</em>, we divide both sides of the equation by 63 to get 4 = t which means that our principal must be invested for 4 years to earn $252 in interest.

I = $252

R = 7%

P = $900

Find T?

Make T the subject

T -> x R -> x P = I

I -> / P -> / R = T

T = I/PR

T = 252/(7% x 900)

T = 252/63

T = $4

If you choose two cards at random from a deck of 52 cards, what is the probability that it is two diamonds?
kari74 [83]
<h3>Answer:</h3>

1/17 or 0.0588 (without replacement)

<h3>Step-by-step explanation:</h3>

To answer this question we need to know the following about a deck of cards

  • A deck of cards contains 4 of each card (4 Aces, 4 Kings, 4 Queens, etc.)
  • Also there are 4 suits (Clubs, Hearts, Diamonds, and Spades).
  • Additionally, there are 13 cards  in each suit (Clubs/Spades are black, Hearts/Diamonds are red) .

In this case, we are required to determine the probability of choosing two diamonds.

  • There are 13 diamonds in the deck.
  • Assuming, the cards were chosen without replacement;

P(Both cards are diamonds) = P(first card is diamond) × P(second card is diamond)

P(First card is diamond) = 13/52

If there was no replacement, then after picking the first diamond card, there are 12 diamond cards remaining and a total of 51 cards remaining in the deck.

Therefore;

P(Second card is diamond) = 12/51

Thus;

P(Both cards are diamonds) = 13/52 × 12/51

                                               = 156/2652

                                              = 1/17 or 0.0588

Hence, the probability of choosing two diamonds at random (without replacement) is 1/17 or 0.0588.

Estimate the value of<br>9304 ÷93 =​
LuckyWell [14K]

Answer:

100

Step-by-step explanation:

Round 9304 to 9300. 9300/93 is just 100 since 100 * 93 = 9300 (this is something easily recognizable).
