vodka [1.7K]

well, in order to solve this we can put each marble into a fraction.

so for blue it would be 5 over 15 (5/15)

because there are 15 marbles in the bag but only 5 of them are blue!

but if you need a % then just divide the top by bottom

then you get a 33% chance of picking blue! hope this helps!

A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probabili

____ [38]

Given :

A circle is inscribed in a square with a side length of 144.

So, radius of circle, r = 144/2 = 72 units.

To Find :

The probability that the point is inside the circle.

Solution :

Area of circle,

$A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2$

Area of square,

$A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2$

Now, probability is given by :

$P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785$

Therefore, the probability that the point is inside the circle is 0.785 .

At a red-tag sale, all items with red tags have been marked down by 49%. What should be the sale price of a DVD player having a

vampirchik [111]

Original price was $234.95
49% marked down = $234.95 *49 / 100 = $115.13

So now the sale price = original price - price of 49% marked down

sale price = $234.95 - $115.13 = $119.82

Answer: sale price of a DVD player having a red tag marked down by 49% should be $119.82

Hi there!

~

What percentage of 85 is 10?

$= 11.76$

(These are just some tips)

↓↓↓

Take the number and multiple it by 85. Then multiply that by . 01.

To calculate 10 percent of a number, simply divide it by 10 or move the decimal point one place to the left. For example, 10 percent of 230 is 230 divided by 10, or 23.

❀Hope this helped you!❀
