Evaluate 3 + 1 1 t − 9 u 3+11t−9u3, plus, 11, t, minus, 9, u when t = 9 t=9t, equals, 9 and u = 1 1 u=11u, equals, 11.

The correct answer is 3

Step-by-step explanation:

Given the function

f(t, u) = 3 + 11t - 9u

To get the value of the function when t = 9 and u = 11, we will substitute the given variables into the given function to have;

f(9, 11) = 3 + 11(9) - 9(11)

f(9, 11) = 3 + 99 - 99

f(9, 11) = 3

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
