Answer:

x - 3 \geqslant 0

Step-by-step explanation:

The given square root function is

f(x) =  \sqrt{x - 3}

The domain refers to all values of x that will make this square root function defined.

We know that negative values will not be defined for the square root function therefore the expression under the root should be greater or equal to zero.

Hence the inequality that can be used to find the domain of f(x) is

x - 3 \geqslant 0

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.
