Answer:
V= -2000t + 20000
Step-by-step explanation:
Let m be the slope of our function :
- m=(20000-16000)/(0-2)= -2000
- so our function is V= -2000t + b
- b is the intitial price so b = 20000
- then : V= -2000t + 20000
Let's check :
- take the second year : V= -2000*2 +20000 = 16000
- that's true !
Answer:
248.96
Step-by-step explanation:
From this regression output we have the MS Residual or mean squared error to be equal to 61983.1
the question requires us to find the standard error of the estimate. The standard error of the estimate can be gotten by finding the square root of the MSE.

= 248.96
the standard error of the estimate = 248.96
thank you!
Answer:
The child needs a score of 37.2 to move up to the next level of the competition.
Step-by-step explanation:
The mean is the sum of all scores divided by the number of competions. So

In which S is the sum of all her scores and T is the number of competitions.
The child has five competions:
Which means that 
She has to get a mean of at least 36.5, so 
Her scores are: 35.5, 36.3. 36.6, and 36.9. Her last score, i am going to call x. So

The child needs a score of _____ to move up to the next level of the competition.
This score is x. So
