<h3>Answer: 2/21</h3>

=========================================================

Explanation:

"Without replacement" means the card selected is not put back, and we do not put a copy of that card into the deck.

We have 5 yellow cards out of 5+9+1 = 15 cards total. The probability of picking yellow is 5/15 = 1/3. Let A = 1/3.

After picking that yellow card, we have 5-1 = 4 yellow left out of 15-1 = 14 total. The probability of picking another yellow card, after the first one is not replaced, is 4/14 which reduces to 2/7. Let B = 2/7.

Multiply the values of A and B

A*B = (1/3)*(2/7) = (1*2)/(3*7) = 2/21

The probability of picking two yellow cards, without replacement, is 2/21

Which is an arithmetic sequence?

astraxan [27]

Answer: the arithmetic sequence is

3, 10, 17, 24

Step-by-step explanation:

In an arithmetic sequence, the consecutive terms differ by a common difference. This means that the difference between the first term and the second term must equal the difference between the second term and the third term.

Considering the following sequences,

1) 4 - 1 = 3

9 - 4 = 5

There is no common difference and so, it is not an arithmetic sequence.

2) 10 - 3 = 7

17 - 10 = 7

The common difference is 7. So it is an arithmetic sequence.

3) 6 - - 5 = 11

10 - 6 = 4

There is no common difference and so, it is not an arithmetic sequence.

4) 2 - 1 = 1

4 - 2 = 2

There is no common difference and so, it is not an arithmetic sequence.

Which is larger 12 1/6 or 75/6

xz_007 [3.2K]

Hello there! Your answer would be 75/6 is larger than 12 1/6.

Need an Explanation?:

Divide 75 by 6 to start so we can equally look at the numbers.

75/6 = 12.5

We know that .5 is equal to 1/2, so change .5 to 1/2.

That means we now have 12 1/2.

So, which is larger: 12 1/6 or 12 1/2?

Obviously 12 1/2 is larger, so this is the one you should choose.

a car dealer buys a luxury car for $65,200 and sells it for 85,650. What is the percent increase in the price of the cara car de

nika2105 [10]

Answer:

The percent increase in the price of the car is <u>31.36%</u>.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

$=\$85,650-\$65,200\\\\=\$20,450.$

<em>Thus, the price of car increased by $20,450.</em>

Now,to get the percent increase in the price of the car:

$\frac{20450}{65200} \times 100$

$=0.3136\times 100$

$=31.36\%.$

Therefore, the percent increase in the price of the car is 31.36%.
