Variable A is x. Variable B is y. (x,y)
2 , 2, 4, 5, 6, 7, 8, 9
Mean is computed by adding all the numbers in the data set and dividing it by its count.
2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43
43 / 8 = 5.375 rounded to 5.4

Answer:
hello :
the area is : (x+3)(x+7) m²
x² +7x+3x+21
(x²+10x + 21)m²
ASA, HL, and SAS.
AAS wouldn't work, and LA and LL don't exist
Hope this helps!
Solution :
Population proportion, P = 77%
Sample size is given by n = 55
Sample proportion =
Null hypothesis
The population proportion of the fatalities of the drivers that are related to alcohol = 77%
%
Alternate hypothesis,
Therefore, the test statistics =
= -3.2
Critical value = -1.64
and the rejection zone : test zone, -1.645
Therefore, we fail rejecting
p value 0.0582
rejection zone :: p value , 0.01
So we fail to reject
Thus the data does not indicate the population proportion of the drivers fatalities which are related to the alcohols which is less than 77% in the county of Kit Carson.
