Given:

There are 18 freshmen and 15 sophomores. Of the 18 freshmen, 10 are male, and of the 15 sophomores, 8 are male.

Formula used:

Probability for equally likely outcomes:

If an experiment has n equally likely outcomes, and if the number of ways in which an event E can occur is m, then the probability of E is,

P(E)= Number of ways that Ecan occur / Number of possible outcomes

$=\frac{n(E)}{n(S)}$

where, S is the sample space of the experiment.

Let E and F be the two events, then the probability of union of two events is,

$P(E\cup F)=P(E)+P(F)-P(E\cap F)$ .

Calculation:

The total students in the college algebra is 33 students. That is,$n(S)=33$ .

The probability that a randomly selected student is a freshman or female is,

P (freshman or female) = P (freshman) + P (female) — P (freshman and female)

$=\frac{n(freshman+n(female)-n(freshman\text{}and\text{}female)}{n(S)}$

$=\frac{18+15-8}{33}=\frac{25}{33}$

Thus, the probability that a randomly selected student is a freshman or female is$\frac{25}{33}$ .

Given that 1${\mathrm{log}}_{a}\left(3\right)\approx 0.61$ and l${\mathrm{log}}_{a}\left(5\right)\approx 0.9$ , evaluate each of the following. Hint: use the properties of logarithms to rewrite the given logarithm in terms of the the logarithms of 3 and 5.

$C=\frac{5}{9}(F-32)$

The equation above shows how temperature

*F*, measured in degrees Fahrenheit, relates to a temperature*C*, measured in degrees Celsius. Based on the equation, which of the following must be true?1. A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of $\frac{5}{9}$ degree Celsius.

2. A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.

3. A temperature increase of $\frac{5}{9}$ degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.

Let R be the relation on the set {0, 1, 2, 3} containing the ordered pairs (0, 1),(1, 1),(1, 2),(2, 0),(2, 2),(3, 0). Find reflexive, symmetric and transitive closure of R.

A baseball team plays in a stadium that holds 70,000 spectators. With the ticket price at $11, the average attendance has been 29,000. When the price dropped to $10, the average attendance rose to 35,000. Assuming the demand function, p(x)$p\left(x\right)$, is linear, find p(x)$p\left(x\right)$, where x$x$ is the number of the spectators.

*Write p(x)*$p\left(x\right)$*in slope-intercept form.*To break even in a manufacturing business, income or revenue R must equal the cost of production the letter C. The cost the letter C to produce X skateboards is the letter C = 108+21X. The skateboards are sold wholesale for $25 each, so revenue the letter R is given by the letter R = 25 X. Find how many skateboards the manufacture needs to produce and sell to break even. (Hint: set the cost expression equal to the revenue expression and solve for X.)
