Answer:
B
Step-by-step explanation:
The chances of the first student walking to school is 7/30.
Without replacement, there are 29 students left. Hence the chance of the second student walking to school is 6/29 of the original 7/30 chance.
![(\frac{7}{30} )(\frac{6}{29} )=\frac{7}{145}](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%7D%7B30%7D%20%29%28%5Cfrac%7B6%7D%7B29%7D%20%29%3D%5Cfrac%7B7%7D%7B145%7D)
Answer: 2x^3.
Step-by-step explanation:First, we can simplify the 12/6 to 2/1 by factoring our 6. Next, remember that when we divide the same base with different exponents, we subtract the exponents. Thus, x^5/x^2 = x^(5-2) = x^3. Thus, the answer is 2x^3.
Using proportions, it is found that:
- Unit price for the 11.3 ounce package: $0.33 per ounce.
- Unit price for the 29.3 ounce package: $0.31 per ounce.
- The 29.3 ounce package is the better deal.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The unit price is given by the cost divided by the number of ounces, and the better deal is given by the deal with the lowest unit price.
Hence, for the 11.3 ounce package:
u = 3.68/11.3 = $0.33 per ounce.
For the 29.3 ounce package:
u = 8.98/29.3 = $0.31 per ounce.
Due to the lower unit cost, the 29.3 ounce package is the better deal.
