Two middle school classes take a vote on the destination for a class trip. Class A has 25 students, 56% of whom voted to go to S
Kryger [21]

Answer:

The value of <em>n </em>is 15.

Step-by-step explanation:

The combined proportion is computed using the formula:

P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}

The information provided is as follows:

n_{A}=25\\p_{A}=0.56\\n_{B}=n\\p_{B}=0.60\\P=0.575

Compute the value of <em>n</em> as follows:

P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}

0.575=\frac{25\times 0.56+n\times 0.60}{25+n}\\\\0.575(25+n)=14+0.60n\\\\14.375+0.575n=14+0.60n\\\\0.60n-0.575n=14.375-14\\\\0.025n=0.375\\\\n=15

Thus, the value of <em>n </em>is 15.

Help please and explain how you did it
Harrizon [31]

1 yard = 3 feet

10 yards = 30 feet (multiply both sides by 10)

------------------

1 yard = 3 feet

2/3 yard = 2 feet (multiply both sides by 2/3)

-------------------

10 yards + 2/3 yard = 30 feet + 2 feet = 32 feet

<h3>The final answer is 32 feet</h3>
