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

Answer:
Step-by-step explanation:
Given that the lengths of the sides of a triangle are consecutive integers
Since side cannot be negative we can assume that the sides are
a, a+1 and a+2 where a>0
The largest angle is opposite side a+2 and smallest is angle opposite a
Using sine formula and the given information that the largest angle is twice the smallest angle
we get
Cross multiply to get
Since sin 2A = 2sin A cos A
we get
