function : y = (-x) - 6
<u>Find x-intercept</u> :
- (-x) - 6 = 0
- (-x) = 6
- x = -6
<u>Find y-intercept</u> :
- y = (-0) - 6
- y = -6
mark these two points on both the axis and draw a straight linear graph.
passes coordinates : (0, -6), (-6, 0)
Answer:
(a) mean = 377.5ml. standard deviation = 4.33
(b) 0.333
(c) 384.25 ml
Step-by-step explanation:
(a)The mean:
The standard deviation:
(b)
(c)P(x > m) = 0.95
So the volumn of shampoo should be 384.25ml to exceed 95% of containers.
