A circle is inscribed in a square. A point in the figure is selected at random. Find the probability that the point will be in t
hram777 [196]
P of selecting point on the shaded region   = shaded area/whole area 
<span>P( selecting point on the shaded ) = ( the four shaded circles ) / the whole square </span>
<span>P of  selecting point on the shaded  = ( 4 * ( π * r^2 ) )/ x^2 </span>
<span>P of selecting point on the shaded = ( 4 * ( π * (x/4)^2 ) )/ x^2 </span>
<span>P of  selecting point on the shaded  = ( 4 * ( π * x^2/16 ) )/ x^2 </span>
<span>P of  selecting point on the shaded = ( π * x^2/4 )/ x^2 </span>
<span>P of  selecting point on the shaded = x^2( π/4 )/ x^2 </span>
<span>P( selecting point on the shaded ) = π/4 ≈ 0.7854 ≈ 79%
 =80%

HELP ME!!! Then I will help you on a question.
Firlakuza [10]

Answer:

$150

Step-by-step explanation:

Let the account earns 5% APR as simple interest for the invested principal.

Now, the formula of simple interest gives that,

A = P(1 + \frac{rt}{100}), where A is the final amount, P is the principal amount invested, r is the % of interest and t is the number of years for which the principal is invested.

So, the interest earned will be given by, I  = P \times \frac{rt}{100}

Hence, in our case, $300 is invested for 10 years at a simple interest of 5%. So,  I = 300\times \frac{5 \times 10}{100} = 150 dollars.

Therefore, the amount of interest earned will be $150. (Answer)
