Concept explainers

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

[Statistics] Use R or RStudio Context of the problem:Fire damage in the United States amounts to billions of dollars, much of it insured. The time taken to arrive at the fire is critical. This raises the question, Should insurance companies lower premiums if the home to be insured is close to a fire station? To help make a decision, a study was undertaken wherein a number of fires were investigated. The distance to the nearest fire station (in miles) and the percentage of fire damage were recorded. Here is the data set: Distance Percent7.5 688.3 666.2 341.6 305.6 706 624.3 478.1 725.7 400.3 531.6 182.5 485.8 535.3 486.3 643.4 526.2 613.2 346.3 656.1 664.6 336.7 760.5 343.2 465.3 555 334.8 466.4 490.2 174.9 476.2 637.6 696.6 542.9 522.1 434.8 358.1 581.2 54.6 464 576.1 400.8 395.9 426.5 626.5 527.5 767.2 676.7 454.1 234 334.8 594…
Gender and Frequency of Status Updates on Facebook The Pew Research Center conducted a survey of randomly sampled American adults, asking them about their use of social networking sites such as Facebook. The table below shows the self-reported frequency of status updates on Facebook by gender.

Null? test statistics? p value? conclusion for hypothesis
-In statistics, the percentage is the same or equivalent to the proportion (p). Percent means per 100. For example, if there are 1,000 residents in a town, and 60% are Democrats, then, on average, 60 out of each 100 are Democrats. You determine the total number of Democrats by converting the percentage to a proportion, .60, and multiplying .60 x 1,000, which equals 600. -To determine a percentage, we divide the part by the whole and multiply by 100. So, if 8 out of 234 seniors are reported to have tried Meth, we calculate the percentage: 8/234 0.0342 and multiply 0.0342 x 100= 3.42%. -Remember: when you multiply by 10, move the decimal point one place to the right3; when you multiply by 100, move the decimal point two places to the right, etc. Answer the questions that follow the Table below Adolescents at three drug treatment centers were surveyed. The questionnaire used consisted of 102 questions and was divided into four sections. The third section asked about past drug use. The…
ANOVA Tests and Independent & Dependent Variables COLLAPSE How are the treatments in an ANOVA test similar to independent and dependent variables? How are they different?
True or False? If False, explain: a) The sample is the group of people on whom we wish to draw statistical interference. b) The Mean Square Error from a regression model is an example of a descriptive statistic. c) Getting enough power (so that we are able to conclude a non-zero slope in a scenario where the true slope is non-zero) is achieved primarily by increasing sample size.
