Answer:
Choice B
Step-by-step explanation:
Divide both of the choices by the price and ounces. You will find that the unit rate of choice B is lower.
Work
3.49/25=0.14
4.79/45=0.106
Therefore choice B has the lowest unit rate and that is the answer!
Answer:
"Confounding Variable"
Step-by-step explanation:
According to my research on statistical studies, I can say that based on the information provided within the question the term being defined in the question is called a "Confounding Variable". This is a variable that affects both the dependent variable and independent variable, this then causes a confusion in their relationship.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
3 times because if he needs 3/4 cup the. you should use it 3 times. (3/4÷1/4=3)
Let's rewrite the binomial as:
![(1 - 2x)^{19}](https://tex.z-dn.net/?f=%281%20-%202x%29%5E%7B19%7D)
![\text{Binomial expansion:} (1 + x)^{n} = \sum_{r = 0}^n\left(\begin{array}{ccc}n\\r\end{array}\right) (x)^{r}](https://tex.z-dn.net/?f=%5Ctext%7BBinomial%20expansion%3A%7D%20%281%20%2B%20x%29%5E%7Bn%7D%20%3D%20%5Csum_%7Br%20%3D%200%7D%5En%5Cleft%28%5Cbegin%7Barray%7D%7Bccc%7Dn%5C%5Cr%5Cend%7Barray%7D%5Cright%29%20%28x%29%5E%7Br%7D)
Using the binomial expansion, we get:
![\text{Binomial expansion: } (1 - 2x)^{19} = \sum_{r = 0}^{19}\left(\begin{array}{ccc}19\\r\end{array}\right) (-2x)^{r}](https://tex.z-dn.net/?f=%5Ctext%7BBinomial%20expansion%3A%20%7D%20%281%20-%202x%29%5E%7B19%7D%20%3D%20%5Csum_%7Br%20%3D%200%7D%5E%7B19%7D%5Cleft%28%5Cbegin%7Barray%7D%7Bccc%7D19%5C%5Cr%5Cend%7Barray%7D%5Cright%29%20%28-2x%29%5E%7Br%7D)
For the 15th term, we want the term where r is equal to 14, because of the fact that the first term starts when r = 0. Thus, for the 15th term, we need to include the 0th or the first term of the binomial expansion.
Thus, the fifteenth term is:
