Answer:
The answer for this is x=-5
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:
6,18
Step-by-step explanation:
The standard form of a linear equation is Ax + By = C
So the answer is; 1x + 3y = 27
