Given:

Ten students from each of the 15 sections of college algebra were asked about the quality of textbook used in the course.

Types of sampling:

Random Sampling:

Every member of the population has an equal chance of being chosen.

Simple Random Sampling:

Every sample of the population has an equal chance of being getting selected.

Stratified Sampling:

Members of the populations are divided into two or more subgroups which have similar characteristics like gender, age or ethnicity, are termed as strata.

Cluster Sampling:

Population is divided into separate groups termed as clusters which have same characteristics that of entire population and then random sample of clusters are chosen from the population.

Systematic Sampling:

Every${n}^{th}$ member of the population is selected.

Convenience Sampling:

The “convenient” sample is selected from the population.

Since a group of 10 students were selected from each 15 sections of Algebra which act as strata and 10 students are randomly selected from strata all have same characteristics, thus this scenario uses stratified sampling.

Conclusion:

Ten students from each of the 15 sections of college algebra were asked about the quality of textbook used in the course, the study uses stratifidd'sampling method.

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.

A) I only

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.)
