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: You have to use the distributive property of multiplication. You're answer would be 21x+6y.
Step-by-step explanation: 3(7x+2y) You have to take each individual number in the parentheses by three. That will get you 21x+6y.
Answer:
453 adult tickets and 877 student tickets were sold.
Step-by-step explanation:
Given that adult tickets to a basketball game cost $ 5 and student tickets cost $ 1, and a total of $ 3,142 was collected on the sale of 1,330 tickets, to determine how many of each type of ticket were sold the following calculations must be performed:
5 - 1 = 4
1330 x 1 = 1330
3142 - 1330 = 1812
1812/4 = 453
1330 - 453 = 877
877 x 1 + 453 x 5 = X
877 + 2265 = X
3142 = X
Therefore, 453 adult tickets and 877 student tickets were sold.
The surface area of a rectangular prism is:
A=2(LW+HW+LH) in this case:
A=2(24*13+24*29+13*29)
A=2(1385)
A=2770 mm^2
For 20: a<em>(insert greater than or equal to sign) 18</em>
