The aftermath of which mid 1700's North American war led to long-simmering tensions between American colonists and the British,
Anastasy [175]

Answer:

The French and Indian War

Explanation:

The French and Indian War was a conflict between Britain and France in North America. This war lasted from 1754 to 1763.

This war was won by Britain, with the help of the American colonists. One of the military commanders was in fact George Washington.

The British victory at first increased loyalty to Britain in the colonies, but because the war had been very expensive, Britain resorted to increased taxation on the colonies, which naturally led to increased tensions, which would ultimately result in the American Revolution.

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
