See attached PDF. (The censor thinks there are some unseemly words in there.)
Answer:
a: given
b: definition of congruent
c: definition of bisect
Step-by-step explanation:
just took the assignment
Answer:
The range and mean will increase - False
(because only range will increase, mean will decrease)
The mean and median will decrease - True
The mean will decrease but the median will stay the same - False
(Both of mean and median will decrease)
An outlier is more likely to change the median than the mean - False
(An outlier is more likely to change the mean than the median)
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.
