36/121 is the correct answer...

Alex73 [517]3 years ago
3 0

Answer:

36/121

Step-by-step explanation:

Probability is a relation between the amount of appropriate results and the total amount of results.

The total amount of the marbles is 6+5=11

We must take only blue marbles so the amount of appropriate results is 6.

The probability of taking blue marble in the 1st turn is 6/11. Then we put the marble back so the amount of marbles doesn't change. That's why the probability of taking blue marble in the 2nd turn is also 6/11.

But we have to count the probability of taking blue marble in both cases. To do it we must multiply the probability of taking blue marble in the 1st turn and the probability of taking blue marble in the 2nd turn.

(6/11)*(6/11)=36/121

If the volume of a sphere is 36 pi cubic units, what is the radius?
Radda [10]

Answer:

3 units

Step-by-step explanation:

Hello

The sphere volume is:

(4/3)*Pi*r^3

then

36 = (4/3)*Pi*r^3

36/[(4/3)*Pi] = r^3

8,5 = r^3

r = 3

What should be multiplied by the expression in the image to obtain the smallest square
makkiz [27]

Answer:

2xy

Step-by-step explanation:

Here, we want to obtain the number with the smallest square

To get this, we simply find the nearest number square which is 2

The nearest x squared which is x (to get x^4)

The nearest y squared which is y (to get y^2)

Thus, the smallest number so we get a square will be; 2xy

MODELING WITH MATHEMATICS The fire escape forms a right triangle, as shown. Use the Pythagorean Theorem to approximate the dista
anastassius [24]

Answer:

x = 14.13ft

Step-by-step explanation:

Given

See attachment for illustration

Required

Find x

To do this, we apply Pythagoras theorem.

From the attachment, the length of the hypotenuse is 16.7ft

While the length of the opposite/adjacent is 8.9ft

Length x is calculated using:

16.7^2 = 8.9^2 + x^2

x^2 = 16.7^2 - 8.9^2

x^2 = 199.68

Take square roots

x = \sqrt{199.68

x = 14.13ft
