Answer:

Option (2)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area = 4πr²

Here 'r' = Radius of the sphere

We have to calculate the surface area of a sphere with radius r = 9 inches.

By substituting the value of r in the formula,

S = 4π(9)²

Therefore, Option (2) will be the correct option.

First order the numbers from the smallest to the largest:

49.6, 55.1, 57.4, 49.7, 61.1, 43.4,  60.7, 50.1, 50.7, 58.8, 53.9, 43.2,  49.2, 47.9, 51.2

to:

43.2, 43.4, 47.9, 49.2, 49.6, 49.7, 50.1, 50.7, 51.2, 53.9, 55.1, 57.4, 58.8, 60.7, 61.1.

The position of third quartile is:

= (N + 1) * 3/4

= (15 + 1) * 3/4

= 12th position

That number is:

= 57.4

The painting's original price was $3,500.

Step-by-step explanation:

Step 1:

The price now is $500 lesser than 3 times the original price. So

The current selling price = (3 × original price) - $500.

If the current selling price is y and the original price is x, then

y = 3x-500.

Step 2:

For this question, we have y = 10,000. Substituting this in the equation, we get

10,000 = 3x - 500, 3x = 10,500, x = \frac{10,500}{3} = 3,500.

So the original price of the classic painting was $3,500.
