Answer:
6973568802
Step-by-step explanation:
I memorized the equation: A(n) = A(1)*d^(n-1).
You can plug into the equation A(21) = 2*3^20, which can be solved to 6973568802. (I solved this step through a calculator by finding 3^20, then multiplying that by 2 to get 6973568802.
Hope this helps!
Answer:
B (-1, 1.5)
Step-by-step explanation:
Add the x coordinates together and divide by 2: (-4 + 2) = -2/2 = -1.
The only option with (-1) as an x-coordinate is B, and that is the answer.
Answer:
<h3>Option a) Influential point is correct.</h3><h3>∴ the point P(194,364.2) is an influential point.</h3>
Step-by-step explanation:
Given that the regression equation for a set of paired data is = -23.8 + 2x. The values of x run from 100 to 400.
A new data point, P(194, 364.2), is added to the set.
From the given we can write it as y = -23.8+2x
Put x=194 in the above equation we get,


= 364.2
<h3>
∴ y(194)=364.2</h3>
Hence, point P(194,364.2) is on regression line and it is not outlier.
<h3>
∴ the point P(194,364.2) is an influential point.</h3><h3>Hence option a) Influential point is correct.</h3>
