Answer:

1.3344

Step-by-step explanation:

Given is the rainforest data.

Let X be the random variables

Then X has mean as 7 and variance as 12.405

SD of X = square root of variance = 3.522

We know that

Z = \frac {X-\mu}{\sigma}\\=\frac{11.7-7}{3.522} \\=1.3344

Z value when x = 11.7 is +1.3344

Answer:

Mean B =μ= 7

Standard Deviation =A=σ ≈ 3.522

Variance =σ²=12.405

X=Score=Data Point=11.7

As, Z=\frac{X- B}{A}

z-score for the Score 11.7

=\frac{11.7-7}{3.522}\\\\=\frac{4.7}{3.522}\\\\Z=1.3344

Find a new function g(x) transformed from f(x)=-x-2 such that g(x) is perpendicular to f(x) .
sineoko [7]

The new function is g(x) =-1(1/-x) +2.

The transformation of function f(x) to function g(x) is given by g(x)=A f(Bx+ H)+K. where the constant A scales the function vertically. (A negative A reflects the function about the x-axis B scales the function horizontally. (A negative B reflects the function on the y-axis.) H shifts the function horizontally, and K shifts the function vertically.

Convert f(x) to g(x)

where the conversion is g(x)=f(x)+2.

A perpendicular line has negative reciprocal slopes, so for g(x) to be perpendicular to f(x), we need to get the negative reciprocal of -x, which is -1(1/-x)

So, f(x)=-x-2  ; m = -1

From the above information, we get g(x) as follows.

g(x) =-1(1/-x) +2

More problems related to finding new functions for a given function are below.
