Step-by-step explanation:
Sung Lee invests $3,000 at age 18.
He hopes the investment will be worth $6,000 when he turns 25, that is, after 7 years.
The interest compounds (Compound Interest). The formula for the final amount in a compound interest is:
where P = Principal (Amount invested) = $3000
A = final amount = $6000
R = rate
T = number of years = 7 years
This implies that:
Find the 7th root of 2:
=> R = 10.4%
Hence, the rate would need to be 10.4% for him to achieve his goal.
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.

Step-by-step explanation:
This problem brothers on the mensuration of solid shapes, a cone.
we know that the expression for the volume of a cone is
let the radius r of the cone be=
and the height h is =
we can now solve the expression that represents the volume of the cone, in cubic units.
