Answer:

a) The inverse of the function is F=\frac{9}{5}C+32

b) The domain of the inverse function is C>1348.70.

Step-by-step explanation:

Given : The formula C=\frac{5}{9}(F-32), where F>2459.67 express the Celsius temperature C as a function of the Fahrenheit temperature F.

To find : a) A formula for the inverse function and interpret it.

b) What is the domain of the inverse function?

Solution :

a) The formula C=\frac{5}{9}(F-32)

The inverse function of the given formula is the value of F.

Taking F to one side and rest term to other side,

\frac{9}{5}C=(F-32)

\frac{9}{5}C+32=F

Therefore, The inverse of the function is F=\frac{9}{5}C+32

i.e. Fahrenheit temperature F as a function of the Celsius temperature C.

b) The domain of the inverse function.

We have given, F>2459.67

Substituting in the formula,

C=\frac{5}{9}(F-32)

C=\frac{5}{9}(2459.67-32)

C=\frac{5}{9}(2427.67)

C=1348.70

The domain of the inverse function is C>1348.70.

The area under a particular normal curve between 6 and 8 is 0.695. A normally distributed variable has the same mean and standar
TiliK225 [7]

Answer:

69.5%

Step-by-step explanation:

A feature of the normal distribution is that this is completely determined by its mean and standard deviation, therefore, if two normal curves have the same mean and standard deviation we can be sure that they are the same normal curve. Then, the probability of getting a value of the normally distributed variable between 6 and 8 is 0.695. In practice we can say that if we get a large sample of observations of the variable, then, the percentage of all possible observations of the variable that lie between 6 and 8 is 100(0.695)% = 69.5%.
