Answer:
<u>12 years</u>
Step-by-step explanation:
Let Kishor's present age be denoted by x.
According to the question :
- He will 3 times as old as he was 4 years ago after 12 years
Therefore, the equation is :
Solving :
- x + 12 = 3x - 12
- 3x - x = 12 + 12
- 2x = 24
- x = <u>12 years</u>
<u></u>
Hence, Kishor's present age is <u>12 years</u>.
f(x) + n - move the graph n units up
f(x) - n - move the graph n units down
n · f(x) - stretch by n in the y-direction
1/n · f(x) - compress by n in the y-direction

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
