Step-by-step explanation:
The data which represents the battery life, in hours, experienced by six users is given below:
10 14 14 16 13 8
To determine the point estimate for the web browsing battery life of the iPad, we find the mean number of hours.
The point estimate for the web browsing battery life of the iPad is: 12.5 hours
9514 1404 393
Answer:
$7.10
Step-by-step explanation:
Nevach's rate can be found by using x=1 in the equation for his pay.
y = 28.5 × 1 = 28.50 . . . . dollars
Carson's hourly rate can be found by dividing dollars by hours:
$214/(10 h) = $21.40/h
Nevach's rate exceeds this by ...
$28.40 -21.40 = $7.10
Nevach earns $7.10 more per hour.
80 units
Step-by-step explanation:
Step 1 :
Given,
The function representing the height is y = 4x^2-32x+80
where the x represents the time after they jumped and y represents their height above ground.
We need to find the platform's height.
Step 2 :
Since x represents the time after they jumped, x = 0 when they have not started jumping and the corresponding y will give the height before they start jumping which would be the height of the platform
Step 3:
When x = 0 we have
y = 0-0+80 = 80
So the height of the given platform is 80 units.
