Im guessing the first answer
Answer:
m=-12
Step-by-step explanation:
Let's solve your equation step-by-step.
1 / 3
m= −4
Step 1: Multiply both sides by 3.
3*(
1 / 3
m) = (3) * (−4)
m=−12
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%
