The increase in a person’s body temperature T(t), above 98. 6ºF, can be modeled by the function T (t) = StartFraction 4 t Ove
kvv77 [185]

The meaning of the horizontal asymptote for the given function is that;

The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses

We are told the increase in a person's body temperature above 98.6°F can be modeled by the function;

T(t) = 4t/(t² + 1)

Where;

t represents the time elapsed

Now, let us find a way to simplify the function so that t at the numerator is removed.

Thus, we will now have;

4t/(t² + 1) = 4/(t + (1/t))

To get the horizontal asymptote, we have to find the limit of the function as t approaches infinity.

Thus;

Lim t ➡ ∞ gives;

T(∞) = 4 × 1/(∞ + (1/∞))

T(∞) = 4 × 0

T(∞) = 0

This means that y = 0 is the horizontal asymptote of the function.

Thus, in conclusion The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses

1. A senator is thinking about running for president. But she will only do so if more than 60% of the voters view her favorably.
OLga [1]

The senator is faced with the making a decision to run for President, based

on the conclusion she can make from the data she gathers.

The statistical method that would be best for her to use is <u>inferential </u>

<u>statistic method</u> such as finding the percentage of supporters she has to a

given <u>confidence level</u>.

Reason:

The two main types of statistical methods are;

Inferential statistics methods; Theses are methods used to reach a

conclusion that extends past the given or available data.

Descriptive statistics methods; Theses are statistical method used as a

summary of a data set.

Given that the senator is trying to draw conclusion based on the data she

gathers, she should use inferential statistic method.

The type inferential statistic method that can be used is the confidence

interval.

From the data collected, the proportion of voters that view her favorably is

used at a given confidence level to determine the true proportion of voters

that view her favorably.

Therefore;

The statistical method that would be best for her to use is the

finding of the <u>confidence interval which is a inferential statistic method</u>.
