This is a ratio problem. You only need solve the ratio of the sand.
<u> 48 </u> <u /> = <u> n </u> <u />
1 156
(48)(156) = 1(n) (cross multiplying)<span>
</span>
7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.
The correct answer is no.
You can factor out a 3t first, resulting in:
Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:
Simplify, you get your
x's:
To write the equation in simplified form, you just write it this way:
That's your answer ^
Answer:
x 2-2 3-3
y 5 5 7 7
Step-by-step explanation:
Each domain, or x value, can only be matched with one y value, so given this, the third one is the answer since every domain is only matched with one range, or in other words, there are no repeating domains in on the x row of the table.
Answer:
Step-by-step explanation: This is a question under linear regression analysis.
The question is trying to relate sales (in $1000) and and advertising.
Both sales and advertising are variables and are connected by the equation
Y = 32x + 8
Which is a linear regression equation of 2 variables.
Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.
At $1 of adverts, we have $40 of sales.
We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)
Y = 32(1) + 8
Y = 32 + 8
Y = $40.
