Answer:
y=-12/5x+62
Step-by-step explanation:
to solve this i turned two point form, 5,50 and 17 1/2,20, into slope intercept form by using the formula y-y1=(y2-y1/x2-x1)(x-x1), which when input with the data becomes y-50=(20-50/17 1/2-5)(x-5) which then becomes y-50=-12/5(x-5), then y-50=-12/5x+12, and finally y=-12/5x+62
Answer: See explanation
Step-by-step explanation:
a. Predict the sales resulting from a $15,000 investment in inventory and an advertising budget of $10,000.
To solve this, in the regression equation, we have to replace x1 with 15 and then replace x2 with 10. This will be:
y = 25 + 10x1 + 8x2.
y = 25 + 10(15) + 8(10)
y = 25 + 150 + 80
y = 255
Therefore, the predicted sales is 255.
b. Interpret b1 and b2 in this estimated regression equation.
A change in b1 which is the inventory investment will bring about a change of 10 units in the sales as long as other values are constant.
A change in b2 which is the Advertising expenditure will bring about a change of 8 units in the sales as long as other values are constant.
Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}
