Answer:
Y = - 12.55X1 + 276.52
Step-by-step explanation:
Given the data:
Age of child :(X) : 4, 6, 10, 13, 14, 17
Time (seconds) (Y) : 230, 205, 132, 119, 108, 62
Using technology, the linear regression equation obtained using the data Given is :
Y = - 12.55X1 + 276.52
Where :
Slope = - 12.55
Intercept = 276.52
This also indicates that a negative slope is present and hence a negative relationship between age of Child and time in seconds.
Answer:
90% chance that it could happen.
I'm pretty sure it's 22%
If it's not, then I'm sorry!!
The answer is letter is C. 19.5 Because you divide
5(4+y) is the correct answer, you would be adding 4 and y then multiplying the sum by 5
