Scores on an achievement test (a) are related linearly to scores on another test (b). Here are two students' scores a = 500, b = 100 and a = 680, b 127. Use the ordered pairs (a, b). a. Find linear question for these data points

b. Use this linear equation to predict the score on the B test for a student with a score of 700 on the A test​

answer: 1 + 1 = 11

step-by-step explanation:

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

definitely a. the others have almost all data points on one side of the line.
