I need help with those 2 (Number 7 can y’all please just pick some random lines and put the numbers like-example. (0,-2) and (4,7) that will be the first line- like that please and I gotta show work :( please help a girl out I will add more points thanks so much. God bless y’all

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

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
