Given:
Profit = 17,500
advertising dollar = 1,020

regression line:

Profit = 372.60 + 17.2(advertising dollar)
17,500 = 372.60 + 17.2(1020)
17,500 = 372.60 + 17,544
17,500 = 17,916.60

There is a residual value of 416.60. 

17,916.60 - 17,500 = 416.60

Oliver buys yen stamps each costing 77cents
krok68 [10]
Hi!
I think that you misspelled the question, and you mean that Oliver bought "ten", not "yen" stamps- yen is the currency of Japan.

So we have 10 stamps of 77 cents each:

10*77=770 cents

He has to pay 770 cents, or since 100 cents are one dollar, 7 dollars and 70 cents.

What is the missing value in x2y8 · x3y? = x5y5?
sweet-ann [11.9K]

Answer:

-3

Step-by-step explanation:

To find:

The value of '?' in the following expression:

x^2y^8.x^3y^? = x^5y^5

Solution:

First of all, let us have a look at a few rules of the exponents:

1.\ a^b.a^c=a^{b+c}

2.\ a^b.a^{-c}=a^{b-c}

Let us apply these rules and try to find out the missing value ('?') in the given expression.

Left Hand Side (LHS):

x^2y^8.x^3y^?\\\Rightarrow x^2.x^3.y^8.y^?\\\Rightarrow x^{2+3}y^{8+?}\\\Rightarrow x^{5}y^{8+?}

Now, let us compare the LHS with RHS, we get:

x^{5}y^{8+?} = x^{5}y^{5}

Dividing with x^5 on both sides:

y^{8+?} = y^5\\\Rightarrow 8+? = 5\\\Rightarrow ? = 5-8 \\\Rightarrow ? =-3

Therefore, the missing value in the expression is <em>-3.</em>
