Choose the function that has the same graph as y=-4 cos(x-pi). y=-4sin(x-pi), y=-4sin(x-pi/2), y=-4sin(x+pi)

answer: a) 56% women

b)44% men

step-by-step explanation:

at least two

step-by-step explanation:

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
