Lol please help for a brainlist and pls show work In order to find out the density of a small rock, Eddie dropped the rock into a graduated cylinder fill with 52.5 mL of water. The level of the water went up to 68.1 mL. Eddie then placed the rock on a triple beam balance, and its mass was 27.69 g.
What is the volume of the rock?

What is the density of the rock?

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

idk wbu

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
