Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)

Slope = (-2)
38) (7 , 0) & (3 , 2)

39) The line is parallel to x-axis and so its slope is 0
Slope = 0
40) The line is parallel to y-axis and so its slope is undefined
Slope = undefined
32x^5/7 This is the answer for that equation.
Answer:
No, there is not a significant difference
Step-by-step explanation:
The sample mean (1.3) is less than the sample standard deviation (1.9). The sample mean would have to be greater than 1.9 for there to be a significant difference
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5
