Answer:

The correct option is D. 9/38x9/38 =81/1444

Step-by-step explanation:

Total number of marbles in the bag = 38

Number of white marbles in the bag = 14

Number of gray marbles in the bag = 9

Number of blue marbles in the bag = 15

We need to find the probability that Jane takes out a gray marble in both draws

$\text{Probability that Jane draws gray marble in first draw = }\frac{9}{38}$

Given that : Then Jane replaces the marble for the second draw

$\text{Probability that Jane draws gray marble in second draw = }\frac{9}{38}$

$\text{Probability that Jane draws gray marble in both draws = }\frac{9}{38}\times \frac{9}{38}$

$\text{Probability that Jane draws gray marble in both draws = }\frac{81}{1444}$

Therefore, The correct option is D. 9/38x9/38 =81/1444

If the area rectangle below us 39 square feet find the x value

Leya [2.2K]

Answer:

x=5 and x=-11

Step-by-step explanation:

(x-2)(x+8)=39

$x^2+6x-16=39$

Subtract 39 from both sides

$x^2+6x-55=0$

Factor:

(x-5)(x+11)=0

Set factors to 0.

x-5 =0

x+11 =0

x=5, x=-11

Answer and explanation please

Alisiya [41]

Probability=number of specific outcomes/number of total possible outcomes...there are 16 pieces in all.

So the probability of picking a king is 1/16

And the probability of picking a pawn is 8/16=1/2

The probability of these two events happening in a row is:

P(k)*P(p)=(1/16)(1/2)=1/32

A sinking fund is established to discharge a debt of $20,000 in 15 years. If deposits are made at the end of each 6-month period

Anna71 [15]

Answer:

the amount of each deposit is $45,555

Step-by-step explanation:

The computation of the each deposit is shown below:

Given that

Future value be $20,000

Time period = 15 × 2 = 30

And, the rate = 5% ÷ 2 = 2.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($20,000 × 2.5) ÷ (1 + 0.025)^30 - 1

= $50,000 ÷ 1.0975675791

= $45,555

Hence, the amount of each deposit is $45,555
