<span> Write an exponential growth function to model the situation. A population of 
422,000 increases by 12% each year. 
2. Describe the transformations (from the parent function) of this exponential 
function: y=3(2^x-1)+1 
3. Find the inverse function of g(x) 
g(x)=7x+18/2</span>

consider the following scenario: Assume daily protein intake values in a population of athletes are known to have a standard dev
Kipish [7]

Answer:

The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96*\frac{58.6}{\sqrt{267}} = 7.03

The lower end of the interval is the sample mean subtracted by M. So it is 77 - 7.03 = 69.97g.

The upper end of the interval is the sample mean added to M. So it is 77 + 7.03 = 84.03g.

The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.

Consider the line y=-1/2x+8
OverLord2011 [107]

Given parameters:

Equation of the line is y = -\frac{1}{2} x + 8

Unknown:

Slope of line parallel to this line = ?

Slope of line perpendicular = ?

Solution:

A line parallel to this line will have the same slope with it.

A line perpendicular will have the negative inverse of this slope;

Slope of line  = - \frac{1}{2}

Slope of line parallel to this line = -\frac{1}{2}

Slope of line perpendicular = negative inverse = -( -(\frac{1}{\frac{1}{2} }))   = 2

So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2
