To figure out the difference you would subtract 294 from 453.
So 453-294=159
Answer: a) 6, 0, 10 b) yellow/orange line
Step-by-step explanation:
a) Plug the x in the y functions, y = 2x² + x
when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6
when x = 0, y = 2(0)² + (0) = 0 + 0 = 0
when x = 2, y = 2(2)² + (2) = 8 + 2 = 10
b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.
And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.

Answer:
0.8945
Step-by-step explanation:
The average life of smokers,
is 60 months
Standard deviation is 8 months
Random sample, n is 30 smoke detectors

= 
= 
= P(-1.37 < Z < 2.05)
= P(Z < 2.05) - P(Z < -1.37) Then from the standard tables, the Z values are 0.9798 for Z=2.05 and 0.0853 for Z=-1.37
= 0.9798 - 0.0853
= 0.8945
Therefore, the probability that a random sample of 30 smoke detectors will have a lifetime between 58 months and 63 months is 0.8945
