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

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.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
