A regression analysis between demand ( y in 1000 units) and price ( x in dollars) resulted in the following equation = 9 – 3 x The above equation implies that if the price is increased by $1, the demand is expected to.

a. increase by 6 units
b. decrease by 3 units
c. decrease by 6,000 units
d. decrease by 3,000 units

D. Decrease by 3000 units.

Step-by-step explanation:

We are given the regression equation as Y=9-3X, where Y is demand in 1000 units and X is price in dollars.

Suppose initially the price is $1, so demand is {(Y=9-3*1) = 6} i.e., 6000.

And now we increased our price to $2.so demand is {(Y=9-3*2) = 3} i.e., 3000.

So, by increasing our price by $1 demand decreased by 3000 units.

So, our ans is d.

I hope I have cleared your doubt.

Have a very good day.

Hnmmmn not sure

7days is 168 hours in decimal form it is just 168 there is no decimal form for this because it is like 168.0 and there is no number you are dividing it by for it to be a decimal.hope this
