The probability that it is less than 11.9 inches long will be 0.11304.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
A manufacturer knows that their items have a normally distributed length, with a mean of 14.2 inches, and standard deviation of 1.9 inches.
If one item is chosen at random.
Then the probability that it is less than 11.9 inches long will be
Then the z-score will be
z = (11.9 – 14.2) / 1.9
z = –1.21
Then the probability will be
P(x < 11.9) = P(z < –1.21)
P(x < 11.9) = 0.11304

Sure of course. idc boutpoints email me. message me for my email and i can give u step by step explanations of anything u need
A) h(x) = g(x) + 30
The term g(x) represents the cost of the cable service minus the startup fee. Also, B, C, and D choices do not represent $30 as a one-time startup fee, so they are immediately wrong answers.
Good luck!
Answer:
The answer is 800
