Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
Answer:
Graph (0, 25) and (50, 0)
Step-by-step explanation:
Intercept form of an equation for a line is ...
x/(x-intercept) + y/(y-intercept) = 1
Dividing each equation by the constant on the right can put it into this form.
First equation:
t/42 + f/42 = 1
Second equation:
t/50 + f/25 = 1
This tells you the second equation can be graphed using the points ...
... (50, 0) and (0, 25) . . . . . matches the second selection
