To make plaster, Kevin mixes 3 cups of water with 4 pounds of plaster powder. Jenny makes plaster using a ratio of 4 cups of water to 5 pounds of plaster powder. Whose recipe uses more water? Answer/Explanation:

Kevin and Jenny each use 12 cups of water to make plaster. Who will make more plaster?
Answer/Explanation:

angle addition postulate

2x=56

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

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

i think the answer is c sorry if it's wrong
