The number of people who caught a col is 8t-5t^2+t^3,. A9nd the number of people who recovered are t-t^2+1/5t^3. Write a polynomial for people who are still sick

Answers

Answer 1

Answer: well.. so many folks caught a cold
so many off that total, recovered,
keep in mind that, the folks who recovered
are just a fraction of the ones who were
sick

so... simply subtract the "recovered" polynomial,
from the "caugh cold" polynomial, namely
$\begin{cases} 8t-5t^2+t^3\impliedby &\textit{caught a cold}\n \textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\n \cfrac{5-t^2+1}{5t^3}\impliedby &recovered \end{cases} \n \quad \n\ [8t-5t^2+t^3]-\left[ \cfrac{5-t^2+1}{5t^3} \right]\implies \textit{still sick}$

Answer 2

Answer: The number of people who caught a col is 8t-5t^2+t^3,. A9nd the number of people who recovered are t-t^2+1/5t^3.

A company can use two workers to manufacture product 1 and product 2 during a business slowdown. Worker 1 will be available for 20 hours and worker 2 for 24 hours. Product 1 will require 5 hours of labor from worker 1 and 3 hours of specialized skill from worker 2. Product 2 will require 4 hours from worker 1 and 6 hours from worker 2. The finished products will contribute a net profit of $60 for product 1 and $50 for product 2. At least two units of product 2 must be manufactured to satisfy a contract requirement. Formulate a linear program to determine the profit maximizing course of action. (Hint: the simplest formulation assigns one decision variable to account for the number of units of product 1 to produce and the other decision variable to account for the number of units of product 2 to produce.)

The perimeter of the given figure is 29.7 ft while the area is 63.25 ft².

What is area?

The area is the amοunt οf space within the perimeter οf a 2D shape. It is measured in squareunits, such as cm², m², etc.

Yοu can think οf area as the area inside a given shape οr space. It refers tο hοw much space is taken up. The larger the shape, the larger the area and perimeter οf the shape will be. Nοt tο be cοnfused with vοlume, area οnly refers tο space taken up by a flat οr 2Dοbject.

The perimeter is sum of all sides

Here,

sum of all sides = 1/2 × 2πr + 6 + 8

= 1/2 × (2×3.14×5) + 6 + 8

= 29.7 ft

Area = 1/2 × πr² + 1/2 × 8 × 6

= 1/2 × (3.14×5×5) + 1/2 × 8 × 6

= 63.25 ft²

Thus, the perimeter of the given figure is 29.7 ft while the area is 63.25 ft².

From the records of a health-insurance companies in Pennsylvania, it is known that 58% of the accounts include dental coverage. A researcher would like to take a random sample of 500 accounts to review. Find the standard deviation of the sample proportion in this situation. Give your answer to 4 decimal places. For help on how to input a numeric answer, please see "Instructions for inputting a numeric response."

Answers

Answer: 0.0221

Step-by-step explanation:

We know that the formula to find the standard deviation of the sample proportion is :

$\sigma_p=\sqrt{(p(1-p))/(n)}$

, where p = proportion of success.

n= sample size.

As per given , we have

p=0.58

n= 500

Then, the standard deviation of the sample proportion in this situation would be :

$\sigma_p=\sqrt{(0.58(1-0.58))/(500)}\n\n=\sqrt{(0.2436)/(500)}\n\n=√(0.0004872)\n\n\approx0.0221$

Hence, the standard deviation of the sample proportion in this situation is 0.0221 .
