Step 1

Here, it is given that the class size is negatively associated with the average grade in a college algebra course. Hence, the class size(x) and the average grade in the college(y) are inversely related. Thus, the increase of variable x would decrease variable y.

Step 2

a) Increase in the class size causes worse grades overall in a college algebra course - It cannot be concluded from the given statement because it does not improve the scenario. Increase in the class size may not definitely cause a worsen of grades because there is a probability for the bright students to do better.

b) College algebra classes with larger class sizes typically have a lower average grade - A conclusion must be drawn based on all situations. This can be concluded with the given information as there is always a probability for every class to have bright students who can understand the course irrespective of the class sizes. Average is based on all observations. So, average marks may not decrease all the time.

c) Reducing class size will increase grades in college algebra courses - It is not a suitable conclusion for the above mentioned situation as reduction in the class size would help the students to understand the algebra course better, it is not certain.

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.)
