Answer:
yes
Step-by-step explanation:
because if you multiply 6 and n it is 6n and 6 x 3 are 18 but subtract 4 and it is correct
The data are reported in the attached table.
We define the null hypothesis H₀ as the statement that is believed true until we prove it wrong with the test.
We define the alternative hypothesis H₁ as the statement we want to conclude with our test.
The difference in graffiti before (B) and after (A) will be:
d = A - B.
If the graffiti declined, it means that A will be smaller than B, therefore d should be negative.
Therefore we can set:
H₀ : μd ≥ 0
H₁ : μd < 0
The equal sign would mean that the number of graffiti incidents remained constant, therefore it is part of the null hypothesis.
Therefore the correct answer is B) H₀: μd ≥ 0 versus <span>H₁</span>: μd < 0
Answer:

15 times 2 plus 3
Answer: Neither
Step-by-step explanation:
5x + 2y = 14
2y = -5x + 14
y = -5/2 x + 7; slope m = -5/2
y = –5x + 9 ; slope m = -5.
Parallel lines slopes are equal and perpendicular slopes are opposite and reciprocal.
So both lines are neither parallel nor perpendicular
Answer
C. Neither.
