Answer:
Failed to Reject Null Hypothesis
Step-by-step explanation:
Null Hypothesis: The means from two respective diets are the same Alternative Hypothesis: The two means from the two diets differ.
Fall in Cholesterol (mg/dL)
Diet n Mean SD
Rice 7 14.4 7.8
Vegetable 9 12.19 7.86
Not necessarily, the more correct definition is opposite reciprocal slopes.
The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.
In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.
The given equations are:
1) 2y = -x + 9
⇒ x = 9-2y
2) 3x - 6y = -15
⇒3x = 6y - 15
x = 2y - 5
Equating the values of x, we get:
9 - 2y = 2y - 5
9 + 5 = 4y
14 = 4y
y = 3.5
Using this value of y in equation 1 we get:
x = 9 - 2(3.5) = 2
So, the solution set is (2, 3.5)
Answer:
1 I think but you said they all have the same area
Answer: The answer would be 40 liters
Step-by-step explanation:
first you would divide 2 by 10 which would equal 5 then multiple the 8 liters by 5 which gives you 40
