Is the data point, P, an outlier, an influential point, both, or neither?

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.

a. Influential point

b. Outlier

c. Both

d. Neither

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

Hence, point P(194,364.2) is on regression line and it is not outlier.

9 x 8 divided by (5-3)=36

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
