Answer: The percent of US adults spend above 29 hours per month on PC internet = 50%
Step-by-step explanation:
Given: , US adults spent on average 29 hours per month using the PC internet.
As the me spent on the PC internet follows a normal distribution.
And there is 50% of the population lies above the mean and below the mean.
Then, the percent of US adults spend above 29 hours per month on PC internet = 50%
Answer:
Domain :Set of all real values
Range : -5
Step-by-step explanation:
Here we see the blue line. Assuming it to be the graph of the function we are about to find Domain for.
Here we see that the graph is a straight line , parallel to x axis at y=-5
Hence the function will be
f(x)=-5
Also for every values of x, y =-5. Hence it is defined for all values of x. So the Domain is Set of All Real numbers
However,
For every value of x, the value of y is constant that is -5. Hence The range of f(x)=-5 is {-5}
Subtract 28 from 49 which is 21 picked in the second hour
Mean:12
median:11.5
