Answer:

22.2 ft²

Step-by-step explanation:

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{50}{360}$

= π × 7.13² × $\frac{5}{36}$

= $\frac{7.13^2(5)\pi }{36}$ ≈ 22.2 ft² ( nearest tenth )

The closing price of Schnur Sporting Goods Inc. common stock is uniformly distributed between $16 and $30 per share.

serg [7]

Answer:

a) 0.3571 = 35.71% probability that the stock price will be more than $25.

b) 0.1429 = 14.29% probability that the stock price will be less than or equal to $18.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Uniformly distributed between $16 and $30 per share.

This means that $a = 16, b = 30$

a) More than $25?

$P(X > x) = \frac{30 - 25}{30 - 16} = 0.3571$

0.3571 = 35.71% probability that the stock price will be more than $25.

b) Less than or equal to $18?

$P(X < 18) = \frac{18 - 16}{30 - 16} = 0.1429$

0.1429 = 14.29% probability that the stock price will be less than or equal to $18.

Write an equation that illustrates a number with two decimal places multiplied by a number with one decimal place. The product h

Vilka [71]

Step-by-step explanation:

Let the number with two decimal places be 1.23

Let the number with one decimal place be 4.5

Then 1.23 multiplied by 4.5

= 1.23 × 4.5

= 5.535

The result has more than two nonzero digits.

Note: When you multiply two decimal numbers, the decimal place(s) of the result is the addition of the decimal places of each of the numbers being multiplied.
