One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr
DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K-273)+32.

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

F=95(K-273)+32

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

F-32=95(K-273)

Divide by 95 both side,

\frac{F-32}{95}=K-273

Add 273 both side,

\frac{F-32}{95}+273=K

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

Question o
taurus [48]

The equation -21t - 4 = 10 - 2t has only one solution

<u>Solution:</u>

Given, equation is – 21t – 4 = 10 – 2t  

We have to find how many solutions does the above given equation have  

Now, let us solve the given equation to find the number of solutions it has.

Then, - 21t – 4 = 10 – 2t

Taking like terms to one side of the equation we get,

- 21t + 2t = 10 + 4  

\begin{array}{l}{-19 t=14} \\\\ {19 t=-14} \\\\ {t=-\frac{14}{19}}\end{array}

here we can see only one value of t.

Hence, the given equation has only one solution.

Determine whether the selection process for each sample was random or nonrandom.
stepladder [879]

The selection process for each sample was Random, Hence, Random sampling

This is further explained below.

<h3>Determine whether the selection process for each sample was random or nonrandom.?</h3>

Generally,  During physical education classes, students are randomly assigned to teams by selecting names from a hat or bag containing their names on individual pieces of paper.

There is a designated area at a supermarket for shoppers to leave comments. Each week, a satisfied customer will be randomly selected from the feedback forms submitted to win a gift certificate.

Selection bias

For a research project, physicians must first compile a list of patients. The first ten people on the list will be placed in the placebo group.

A clothes retailer conducts surveys of clients who use its store credit card to better understand its clientele.

We collect five soil samples from the biggest farm in a given area to determine the quality of the soil there.

The distinction between random and non-random sampling is explained.

In random sampling, each sample has the same chance of getting the target variable. When a researcher uses a sampling strategy that is not random, the features of the sample chosen are not based on chance but on factors like their own convenience, their own professional judgment, and their own prior experience.

In conclusion,  During physical education classes, students are randomly assigned to teams by selecting names from a hat or bag containing their names on individual pieces of paper.

There is a designated area at a supermarket for shoppers to leave comments. Each week, a satisfied customer will be randomly selected from the feedback forms submitted to win a gift certificate.
