Step-by-step explanation:

Let:

s - side of the square

d - diameter of the circle

r - radius of a circle

C - circumeference of the circle

AC - area of the circle

AS - area of a square

The formula of a perimeter of a square:

P = 4s

We have P = 40cm.

Substitute:

4s = 40 divide both sides by 4

s = 10 cm

The length of the diameter of the circle inscribed in the square is equal to the length of the side of the square.

Therefore d = s → d = 10 cm.

The length of the circle diameter is two lengths of the circle radius.

Therefore d = 2r → r = d : 2 → r = 10 : 2 = 5 cm.

The formula of a circumference of a circle:

C = dπ.

Substitute d = 10cm, and π = 3.14.

C = 10(3.14) = 31.4 cm.

The formula of an area of a circle:

AC = πr²

Substitute r = 5cm and π = 3.14

AC = 3.14(5²) = 3.14(25) = 78.5 cm².

The formula of an area of a square:

AS = s²

Substitute s = 10 cm

AS = 10² = 100 cm²

In 1990, the profit of the Gamma company was $11.900,848. Each year after 1990profits fell by \$48,263 on average Construct a li

Marina86 [1]

Answer:

$10452958

Step-by-step explanation:

Initial profit = $11900848

Fall rate= $48263 per year

Equation:

P(x)= 11900848 - (x-1990)*48263,

where P(x)= profit at year of x, and 1990<x<2020

P(2020)= 11900848- 30*48263= $10452958

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the

Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201$

0.1201 = 12.01% probability that Alysha will win the bet.
