Gina represents three linear functions in three different forms as shown which list shows gina's three functions in order from l

east to greatest rate of change?
function f x= -2, 1 y= -5, -1
function g is y=-x+9
function h is the coordinate plain on the graph.

The graph is not shown, so I cannot include that in the answer.  As for the other two, while -1 is technically a smaller number than 2/3, in terms of rate of change, it makes a steeper line, so it is a larger rate of change.  In order from least to greatest (except the graph) we have

f, g

The slope of f is given by
m=(y₂-y₁)/(x₂-x₁) = (-1-1)/(-5--2) = -2/-3 = 2/3

g is in slope-intercept form, or f(x) = mx+b; the slope is m. In g, this is -1.

A recent study asked U. S. Adults to name 10 historic events that occurred during their lifetime that have had the greatest impa
Nadusha1986 [10]

Using the z-distribution, as we are working with a proportion, it is found that the 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, the parameters are:

z = 2.575, n = 2000, \pi = 0.77

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 - 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7458

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 + 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7942

The 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.
