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.
Answer:
Tests is 100% Accurate, so by using the formula of random variable probability.
Step-by-step explanation:
Total number of people = 10
Sample space = p(A) = 10
Number of people that have flu = n(s) = 4
Pick random 3 persons, the possibility that they have flue is n(A) = ?
Let X is the random variable, consisting of number of positive flu test,
Tests is 100% Accurate, so by using the formula of random variable probability, we get
P(X) = n (A) / n(S)
P(X) = ¾, is the probability of having positive flu test
Here are some
1 ) 4 ( x - 3 )
2 ) 10 x - 2 x - 12
3 ) 8 x - 4 - 8
Move 50x to the opposite sude so 50x-200>-75
move 200 over so 50x> 125
divide so x>2.5
