The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

<em />x \to<em> number of rows</em>

<em />y \to<em> number of trees in each row</em>

<em />

So, we have:

<em />y = 2x - 10<em> --- twice less than the number of rows</em>

The area of the farm is:

Area = x \times y

Where

Area = 600 --- the number of trees

So, we have:

x \times y = 600

Substitute y = 2x - 10

x \times (2x - 10) = 600

Substitute 50 for x

50 \times (2 \times 50 - 10) = 600

50 \times (100 - 10) = 600

50 \times 90 = 600

4500 = 600

The above equation is not true.

This means that, each row does not have 50 trees

The difference between of two numbers is 9. If the large number is one more than twice the smaller number, find the larger numbe
sleet_krkn [62]

The larger number is 17

<em><u>Solution:</u></em>

Let "x" be the larger number

Let "y" be the smaller number

<em><u>The difference between of two numbers is 9</u></em>

Therefore,

larger number - smaller number = 9

x - y = 9 -------- eqn 1

<em><u>The large number is one more than twice the smaller number</u></em>

Larger number = 1 + 2(smaller number)

x = 1 + 2y ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

<em><u>Substitute eqn 2 in eqn 1</u></em>

1 + 2y - y = 9

1 + y = 9

y = 9 - 1

y = 8

<em><u>Substitute y = 8 in eqn 1</u></em>

x - 8 = 9

x = 8 + 9

x = 17

Thus the larger number is 17

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a king and
STALIN [3.7K]

Answer:

0.0181 probability of choosing a king and then, without replacement, a face card.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of choosing a king:

There are four kings on a standard deck of 52 cards, so:

P(A) = \frac{4}{52} = \frac{1}{13}

Probability of choosing a face card, considering the previous card was a king.

12 face cards out of 51. So

P(B|A) = \frac{12}{51}

What is the probability of choosing a king and then, without replacement, a face card?

P(A \cap B) = P(A)P(B|A) = \frac{1}{13} \times \frac{12}{51} = \frac{1*12}{13*51} = 0.0181

0.0181 probability of choosing a king and then, without replacement, a face card.
