42÷2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The opposite sides of a parallelogram are parallel and congruent, thus
SR = PQ , that is
8a - 4 = 6a + 10 ( subtract 6a from both sides )
2a - 4 = 10 ( add 4 to both sides )
2a = 14 ( divide both sides by 2 )
a = 7
In a parallelogram consecutive angles are supplementary, thus
∠ P + ∠ Q = 180, that is
18b - 11 + 9b + 2 = 180, that is
27b - 9 = 180 ( add 9 to both sides )
27b = 189 ( divide both sides by 27 )
b = 7
Thus c = a + b = 7 + 7 = 14 → B
Answer:
So on this case the best option for the answer would be:
between .01 and .025
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have 
groups and on each group from 
we have 
individuals on each group we can define the following formulas of variation:
And we have this property
The degrees of freedom for the numerator on this case is given by 
where k =4 represent the number of groups.
The degrees of freedom for the denominator on this case is given by 
.
And the total degrees of freedom would be 
We can find the 
And 
And the we can find the F statistic 
And with that we can find the p value. On this case the correct answer would be 3 for the numerator and 16 for the denominator.
So on this case the best option for the answer would be:
between .01 and .025
<h3>Order of Operations: </h3><h3>The steps used to evaluate a numerical expression:</h3><h3> 1) Simplify the expressions inside grouping symbols.

</h3><h3>PEMDAS represents the order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction</h3><h2>Example :</h2><h3>18 – (4 + 2) + (6 × 5) ÷ 3 = [Parentheses first]</h3><h3>Notice: There are no Exponents in this expression.
