How would you explain this methodology and could you identify the independent, dependent, control variables, how would you defen

d the validity and reliability of the variables, and what is the testable hypothesized relationship between the independent and dependent variable?
Data and Dependent Variable

We collected data for 145 countries over the time period 1970-2000.16 The data are structured in terms of country-year observations and, after dropping 72 such cases for which we do not have any information on the migration data (discussed below), our sample comprises 3,919 country-years.17 For the dependent variable, we rely on the information in the Global Terrorism Database (GTD) that defines terrorism as “the premeditated use or threat to use violence by individuals or subnational groups against noncombatants in order to obtain a political or social objective through the intimidation of a large audience beyond that of the immediate victims” (Enders, Sandler and Gaibulloev, 2011, p.321). This data set provides a count variable on the number of terrorist attacks – both national and transnational – that occurred within a country’s geographic boundaries.18 We use a modified version of the count variable of terrorist attacks: due to the skewed distribution of the number of terrorist attacks in a country, which is primarily driven by the large number of zeros in the data, and since our estimators require a (quasi-) continuous dependent variable, we take the natural logarithm of the count after adding the value of 1 (to avoid calculating the log of 0.

The pressure applied to a leverage bar varies inversely as the distance from the object. If 150 pounds is required for a distanc
AlexFokin [52]

Answer:

500 pounds

Step-by-step explanation:

Let the pressure applied to the leverage bar be represented by p

Let the distance from the object be represented by d.

The pressure applied to a leverage bar varies inversely as the distance from the object.

Written mathematically, we have:

p \propto \dfrac{1}{d}

Introducing the constant of proportionality

p = \dfrac{k}{d}

If 150 pounds is required for a distance of 10 inches from the object

  • p=150 pounds
  • d=10 inches

150 = \dfrac{k}{10}\\\\k=1500

Therefore, the relationship between p and d is:

p = \dfrac{1500}{d}

When d=3 Inches

p = \dfrac{1500}{3}\\\implies p=500$ pounds

The pressure applied when the distance is 3 inches is 500 pounds.

You divide -15 on both sides to keep the x alone
-240/ -15=16

Rihanna must put a five dollar deposit down to buy a necklace. If P where presents the full price of the necklace which expressi
natta225 [31]

Answer:

<em>The expression is </em><em>P - 5</em>

Step-by-step explanation:

Rihanna already made a deposit of $5 to buy the necklace (given)

Full price of necklace = P

Let m = how much Rihanna has left to pay

Full price of necklace = amount paid + amount left to pay

= 5 + m

So we equate the two full necklace prices

5 + m = P

m = P - 5

Therefore, the amount Rihanna owes before tax = P - 5

Picking a number that is divisible by 5 from a jar with papers labeled from 1 to 12
kogti [31]
Total number of possible outcomes:12
Number of favourable outcomes:2( since only two numbers divisible by 5 in that range are 5 and 10)
The possibility that you'll pick a number divisible by 5 is 2/12 or 1/6
Hope that's what you're looking for since you didn't specify.
