In order to convert a temperature in kelvin, k, into a temperature in degrees fahrenheit, f, the equation above can be used. which of the following equations correctly expresses the temperature in kelvin in terms of the temperature in

Option C is correct

Step-by-step explanation:

K denotes Kelvin and F denotes Fahrenheit . Kelvin and Fahrenheit are basically units of temperature .

It's not very difficult to convert Kelvin into Fahrenheit or Fahrenheit into  Kelvin .

Simple addition and subtraction will help in such conversions .

Put value you know to get the answer in the desired temperature scale using the appropriate temperature unit conversion formulas .

Fahrenheit is expressed in degrees but Kelvin is not expressed in degrees We need to find which of the given equations correctly expresses the temperature in Kelvin in terms of the temperature in  Fahrenheit .

Correct option is C

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
