Answer:
Step-by-step explanation:
Multiply $120 (cost of haircut) X .18 (18% in decimal form) to get the tip amt.
120 X .18 = 21.60
Now add $120 (haircut) + 21.60 (tip) together to get the total amt. she paid.
120 + 21.60 = $131.60
Carla gave her stylist $131.60 total
Answer: 12
Step-by-step explanation:
Correct Question:
Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. His data are shown in the table. Years Since Tree was Planted vs. Height of Tree
Years since the tree was planted, x
Height of tree in feet, y
2, 17, 3, 25, 5, 42, 6, 47, 7, 54, 9, 69
Using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?
Answer/explanation:
There is no good prediction for the height of the tree when it is 100 years old. If you analyze careful in details the regression calculator you realize that it probably will not valid that far in to the future say 100 years.
This ones kinda hard I'm not really sure, but looking at the table, when f(x) = 1, g(x) = 1. So therefore it is yes, and Im guessing you know the negative and positive x coordinates/zero thing, so I think you should be correct. Sorry if this is wrong, not too sure, but hopefully it gives you a better idea.
