Answer: There is not a good prediction for the height of the tree when it is 100 years old because the prediction given by the trend line produced by the regression calculator probably is not valid that far in the future.
Step-by-step explanation:
Years since tree was planted (x) - - - - height (y)
2 - - - - 17
3 - - - - 25
5 - - - 42
6 - - - - 47
7 - - - 54
9 - - - 69
Using a regression calculator :
The height of tree can be modeled by the equation : ŷ = 7.36X + 3.08
With y being the predicted variable; 7.36 being the slope and 3.08 as the intercept.
X is the independent variable which is used in calculating the value of y.
Predicted height when years since tree was planted(x) = 100
ŷ = 7.36X + 3.08
ŷ = 7.36(100) + 3.08
y = 736 + 3.08
y = 739.08
Forward prediction of 100 years produced by the trendline would probably give an invalid value because the trendline only models a range of 9 years prediction. However, a linear regression equation isn't the best for making prediction that far in into the future.
The answer is c because of Pythagorean’s theorem. a^2 + b^2 = c^2
So 5^2 + 12^2 = 13^2
25+144=169
Answer:
So we can compute the angle θ between u and v using the dot product: θ = arccos ( u · v u v ) . u · v = u vcos(0) = u v > 0. , so u · v = u vcos(π/2) = 0.
Step-by-step explanation:
brainliest please therefore your answer is option 1
The domain is the x-axis and the range is the y axis.
Example:
(-2,4) (6,7) (3,-8)
D:{-2,6,3}
R:{4,7,-8}
Answer:
Multiply both the divisor and the dividend by 10 to make it easier to divide
Step-by-step explanation:
As given division equation in a more suitable format that shows the dividend and the divisor that is = 
so now we we will make the two parts to be whole number
first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places
so, that we multiplying both of them by a 10 will make them whole numbers
so so correct answer is 10
11
