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.

3 cans store 9 tennis balls. Write an equation to represent the realationship
LUCKY_DIMON [66]

Answer:

y = 3x.

Step-by-step explanation:

To find out the equation, put it this way. For every 3 cans, there are 9 tennis balls. So if you put it as 9/3, that means that for every can, there are 3 tennis balls. y = 3x. The x is the variable for how many cans there are. If there are 5 cans, the five would multiply by 3 and then thats your answer.

I hope I helped.

Brainliest would be appreciated.

Have a nice day.
