Suppose a household with 4 people uses 180 litres of water per day on average. 60% of this is hot water. how much water is used?

18.75 gallons

step-by-step explanation:

greater than one

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

idk what the heck he answer is, i’m just putting this here so i finish my account
