Answer:
Step-by-step explanation:
Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.
We have to find values of x such that
and
a=2.33 and b =-2.33 as z values
Let us convert to X values
i.e. values below 19.304 and above 25.496
Hence for x below 19.304 and above 25.496 are significantly low and high.
24.2 length is not significantly high.
Answer:
Step-by-step explanation:
Given function is,
Factors of the numerator = x² - 3x + 2
= x² - 2x - x + 2
= x(x - 2) - 1(x - 2)
= (x - 2)(x - 1)
Therefore, given function will be,
f(x) =
For (x - 2) = 0
For x = 2, denominator will become zero.
Thus for input value x = 2, function will not be defined.
If x ≠ 2, f(x) = x - 1
It's a linear function represented by f(x) = x - 1
Having slope = 1 and y-intercept = -1
And (2, 1) is a hole as shown in the graph.
