x=85.59 degrees
Answer:
The mean of the data: 5,7,5,4,8 is 5.8
Step-by-step explanation:
To find the mean, add up the numbers, then divide them by the number of data points. So 5 + 7 + 5 + 4 + 8 = 29, and 29 divided by 5 is 5.8
X = 5 ... y = 12
x = ? ... y = 30
If you would like to know the value of x when y = 30, you can calculate this using the following steps:
5 * 30 = x * 12
x * 12 =150 /12
x = 150 / 12
x = 12.5
The result is 12.5.
In a function f(x):
set of all the values that x can take is called the domain of the function.
Set of all the values that f(x) (or y) can take is called the range of the function.
Range can have either finite or infinite number of values depending on the function its domain.
For example, f(x) = x^2
can have infinite number of values in range.
whereas :
f(x) = [x] , 0<x<10
where [x] is the greatest integer function,
has finite number of values in its range.
