It is believed that 43% of the US population can play the piano, 28% can play the guitar, 15% can play the harmonica, 12% can pl

melomori [17]

Answer:

The smallest sample size to satisfy the conditions is n=500.

Step-by-step explanation:

The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

$np\geq10\\\\n(1-p)\geq10$

The largest sample size required will be for the minimum p or (1-p).

This happens to be the proportion that can play other instruments: 2%.

Then, we can calculate the minimum sample size as:

$np\geq10\\\\n(0.02)\geq10\\\\n\geq(10/0.02)\\\\n\geq500$

Combine like terms and apply the distributive property to create an equivalent expression:

chubhunter [2.5K]

Answer:

Equivalent expression is $15a+8b$

Step-by-step explanation:

Given expression is,

$2\left(5a+3b\right)+5a+2b$

First step is to apply distributive property. The property states that,

$a\left(b+c\right)=ab+ac$

Applying the property,

$2\left(5a\right)+2\left(3b\right)+5a+2b$

Simplifying,

$10a+6b+5a+2b$

Collecting like terms,

$10a+5a+6b+2b$

Combining the like terms,

$15a+8b$

Therefore, equivalent expression is $2\left(5a+3b\right)+5a+2b=15a+8b$
