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

The cold war between, Soviet Union, United states and China lead to the Vietnam war. The Vietnam war was considered as the proxy war in the cold war.
<u>Explanation:</u>
Although the United states and the Soviet union did not directly participated in the war but they both supported a different part of the war.

Explanation:
Answer:
Thousands of Jewish children survived this brutal carnage, however, many because they were hidden. With identities disguised, and often physically concealed from the outside world, these youngsters faced constant fear, dilemmas, and danger. Theirs was a life in shadows, where a careless remark, a denunciation, or the murmurings of inquisitive neighbors could lead to discovery and death. The Nazis advocated killing children of “unwanted” or “dangerous” groups either as part of the “racial struggle” or as a measure of preventative security. The Germans and their collaborators killed children for these ideological reasons and in retaliation for real or alleged partisan attacks.
