Answer:

Welfare can create a pattern of dependence.

When multiple needs are being met, from housing to food assistance, then it can create a system of dependence for some individuals or households. When every need is being met, then there is no incentive for an individual to better themselves.

Which regression model best fits the data set? (2;13); (4;8); (5;7.5); (8;12)
Levart [38]

The regression model that best fit the data set is : Y=10.35-0.0467X

Explanation:

The equation of a regression line is given by;

Y=a+bX where b is the slope of the line a is the y-intercept , Y is the dependent variable and X is the independent variable

The slope b is given by;

b = n(∑xy)-(∑x)(∑y) / n(∑x² )-(∑x)²

a=(∑y)(∑x²)-(∑x)(∑xy) /n(∑x²)-(∑x)²

n is the sample size = 4

Form a table as;

x            y               xy             x²              y²

2            13              26            4              169

4             8               32            16            64

5             7.5            37.5          25         56.25

8              12              96           64           144

<u>19             40.5          191.5        109         433.25--------sum</u>

<u></u>

a=(∑y)(∑x²)-(∑x)(∑xy) /n(∑x²)-(∑x)²

a=(40.5)(109) - (19)(191.5) / 4(109) - (19)²

a=(4414.5 - 3638.5) / (436-361)

a=776/75

a=10.35

b = n(∑xy)-(∑x)(∑y) / n(∑x² )-(∑x)²

b=4(191.5)-(19)(40.5) / 4 (109)-19²

b=766-769.5 /436-361

b=-3.5/75

b= - 0.04667

The model will be represented by the equation;

Y=10.35 -0.0466X

What was the effect of European Christians wanting to recover the Holy Land from the Muslims?
nadezda [96]
<span>It was the Crusades.  The Crusades was a campaign to regain the Holy Land from the Muslim invaders after they took it over.  Some came to fight for that goal while others joined to see new lands while some were after the riches that be taken from that area.  Many were promised forgiveness of their sins if they joined the Crusades.  Still, some of the effects of the Crusade were that the Mediterranean was open to trade as soldiers and markets were established.  Other effects were that it led to the growth of towns and cities as the nobility sold their lands to join the Crusades and the people gained their freedom. Finally with the growth of towns, feudalism was weakened.</span>
