Answer:
B
Step-by-step explanation:
AP is not congruent to PB
For this case we must solve each of the equations proposed:
A) 
We apply distributive property to the terms within parentheses:
Subtracting 6 from both sides of the equation we have:
Dividing between -12 on both sides of the equation:
B) 
We apply distributive property to the terms within parentheses:
We add 5m on both sides of the equation:
Dividing between 2 on both sides of the equation:
C) 
We apply distributive property to the terms within parentheses:
We subtract 14 from both sides of the equation:
Dividing between -7 on both sides of the equation:
D) -
We apply distributive property to the terms within parentheses:
We add 28 to both sides of the equation:
Dividing between -21 on both sides of the equation:
Answer:
Answer:
5/8 of a quart.
Step-by-step explanation:
That would be 28/32 - 1/4
= 28/32 - 8 /32
= 20/32
= 5/8 of a quart.
Answer:
a. correlation
b. inverse linear correlation exists If the higher the population of students lead to a decrease in test score,
c. yes
Step-by-step explanation:
a. Correlation is a measure of the amount of association existing between two variables.
b. For linear correlation, if points are plotted on a graph and all the points lie on a straight line, then perfect linear correlation is said to exist. When a straight line having a positive gradient can reasonably be drawn through points on a graph positive or direct linear correlation exists,
Similarly,when a straight line having a negative gradient can reasonably be drawn through points on a graph, negative or inverse linear correlation exists,
The results of this determination give values of r lying between +1 and −1, where +1 indicates perfect direct Positive linear correlation and −1 indicates perfect inverse correlation or Negative linear correlation and 0 indicates that no correlation exists.
If the higher the population of students lead to a decrease in test score, there will definitely be a negative correlation between class size and test score. i.e low class size result in high test score which consequently lead to high performance.
c. YES
A negative correlation means low class size result in high test score which consequently lead to better performance.
Answer:
B
Step-by-step explanation:
because the angles 1 and 7 are alternate and equal , we can conclude that p and q are parralel
