Solution: The amount she has to pay for the tip is $5.30, therefore the correct option is option 4.
Explanation:
If Charissa doesn't want to leave pennies on the table, then she has to pay only the amount of tip.
Let the amount for the tip be x.
It is given that the bill for the food is $26.50 and she wants to tip at 20%.
20% of $26.50 =

Answer:
Option c
Step-by-step explanation:
Given that if the coefficient of determination is a positive value, then the regression equation _________
While r the correlation coefficient represents thelinear association between two variables, r has an attached sign.
A positive r represents positive slope and negative r negative slope
But coefficient of determination is the square of r and hence from this R^2 value alone we cannot conclude whether positive or negative relation exists.
As a result,
c. could have either a positive or a negative slope
is right answer
4/3 • pie r^3 is what my math teacher says
