84.50 x 18.0 = 15.21 (tip) so total bill will be 84.50 + 15.21 = $99.71
Answer:
8 slices
Step-by-step explanation:
According to the given situation, the data is as follows
F = unknown number of fruits
Number of fruits ate = 7 slices
Total number of fruits = 15 slices
Here the equation that should be used is
7 slices + x = 15 slices
So, the x is
= 15 slices - 7 slices
= 8 slices
Basically we deduct the both the slices so that the difference between them could come and the same is to be considered
The choose ( 0.25 )
Relative Frequency = Category Frequency / Total Frequencies
Category Frequency (prefer tennis) = 7
Total Frequencies = 28
Relative Frequency = 7 / 28
Relative Frequency = 0.25

By "slope" I assume you mean slope of the tangent line to the parabola.
For any given value of <em>x</em>, the slope of the tangent to the parabola is equal to the derivative of <em>y</em> :
The slope at <em>x</em> = 1 is 5:
The slope at <em>x</em> = -1 is -11:
We can already solve for <em>a</em> and <em>b</em> :
Finally, the parabola passes through the point (2, 18); that is, the quadratic takes on a value of 18 when <em>x</em> = 2:
So the parabola has equation
