I dont know man you gotta ask a question
See photos for solutions and steps :)
Answer:
C. p(x) = 5x - 12.
Step-by-step explanation:
p(x) = 8x - (3x + 12) (Note you have to put the 3x+12 in parentheses).
p(x) = 8x - 3x - 12
p(x) = 5x - 12
Answer:
Ok
Step-by-step explanation:
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%
