X + 2y = 11
x - 2y = -1
---------------add
2x = 10
x = 10/2
x = 5
x + 2y = 11
5 + 2y = 11
2y = 11 - 5
2y = 6
y = 6/2
y = 3
solution is : (5,3)
$185 + $545 = $730
$730 x .20 = $146
$730 - $146 = $584
FINAL COST NOT INCLUDING TAX:
$584
Consider an absolute value inequality.
For example, 3≤|x-7|
this means that x-7 can be
i) 3, 3.4, 5, 7.5 etc
or ii) -3, -3.2, -4.7 etc since these values in abs value all are ≥3
thus the set of all values in i) is represented by x-7≥3, which means x≥10
and the set of all values in ii) is x-7≤-3, which means x≤4.
Thus, the compound inequality is : x≥10 OR x≤4
an absolute inequality corresponding to this compound inequality is 3≤|x-7|
Answer:
33
Step-by-step explanation:
Simplify the expression.
The correlation coefficient between the variables are always between +1 and -1
If the correlation coefficient is near to +1 the degree of relationship between variables is strongly positively correlated. And if the correlation coefficient is near to -1 the degree of relationship between variables is strongly negatively correlated.
Hence at the extremes +1 and -1, there is a strong degree of relationship between two variables
Near to 0 (the middle of the range), there is a weak degree of relationship between two variables
So, the answer would the value the is nearest to 0 since we want a weak relationship
The value that is nearest to 0 is a) 0.10
So, the answer is a)0.10
