Answer and Explanation:

R-square measures whether the variation exists or how much dependence the independent variables on the dependent variables.

R2 = .45 which is quite low. This shows that there is not much variation. In order to increase the R2 the researcher can add more independent variables.

The below part is taken from the internet as the question was incomplete:

Sunny days = 0.5

Intercept = 2.1

The slope shows a positive relationship (direct relationship) with the dependent variable which is crime dependency.

Sunny days is the independent variable.

Intercept is also positive whereas there is significance in the p value which helps in concluding that we will reject the null hypothesis.

Andre45 [30]

Answer:

Normal spoilage rate = 1.6978% (Approx)

Explanation:

Given:

Total unit produce = 11,900 units

Normal spoil unit = 200 units

Abnormal spoil unit = 120 units

Total normal unit produce = 11,900 - 120 = 11,780

Computation of normal spoilage rate:

Normal spoilage rate = Normal spoil unit / Total normal unit produce

Normal spoilage rate = 200 / 11,780

Normal spoilage rate = 0.0169779287

Normal spoilage rate = 1.6978% (Approx)

Why should employees be wary of participating in the grapevine in a business
Kaylis [27]

Although the grapevine supplements what formal communication does not provide sometimes, and creates a sense of unity among employees, they should be wary due it carries partial information and it's more based on rumors; so it's not always trustworthy, especially when it comes to business, because important decisions depend on reliable sources to ensure favorable outcomes.

There are many ways to cash-flow your college education without going into debt. Provide a minimum of five options for cash-flow
Ghella [55]
<span>1. Get a part-time job.
</span>Many college campuses have opportunities to work to earn some extra money or a chance for your work to convert into money towards your tuition.<span>You can have your paycheck be directly deposited into your bank account so you don’t have to worry about cashing a paper check, and if you get a checking account, you can get a debit card to use your money at school for food, books, and other necessities.
</span>2. Sell your notes and study guides on Flashnotes.
Flashnotes is a way to make money doing something you will be doing anyways! This is a great way to help students, review your class material and make money, all at the same time.<span>Typing out the notes will help you remember what you learned, and reading something in someone else’s “voice” will help other students learn better since they are learning from their peers. Sell your papers through social medias and you can then send it through email or blog.
</span>3. Enter sweepstakes.
Many popular stores have surveys that you can take after you make a purchase. Many times, you get a coupon for a percentage off, but some surveys get you entered to win gift cards to the store. This is especially helpful if you shop there and if you typically buy living necessities at the store.

While winning is not guaranteed, if you shop there a lot, you may be able to get entered several times, increasing your chances of winning, compared to those who may not shop there a lot or even those who do not choose to take the survey.

4. Earn gift cards through online rewards websites and apps.

There are websites and apps that allow you to earn points that can be redeemed for gift cards. These sites and apps include Swagbucks<span>, </span>InstaGC<span>, </span>Inbox Dollars<span> and </span>ePoints. Points are earned through taking surveys, playing games, watching videos, and other activities.

Each activity has a specific point amount and they accumulate until you decide that you want to cash them in. Many of these sites give points for online shopping or signing up for offers, but do not sign up and pay for something that you do not really need, since that defeats the purpose.

5. Get paid to write reviews online.
There are websites, like SliceThePie.com, that pay you for reviewing the latest fashions and music. The longer and better your reviews, the more you get paid.

For example, on SliceThePie, while the maximum is typically nine cents per review, there are certain specials that allow you to get paid more. This usually happens on fashion reviews, but some music is occasionally higher paying.

Also, the more stars you have, the more you get paid. Stars are earned through predicting hits. While this is not a means of getting rich quickly, it definitely adds up after you go at it for a while. You can cash out once you reach ten dollars, and you get paid through your PayPal account.
