Answer:

He can randomly survey 50 sixth-graders in the school. Because if he asked 30 people in the band some people might be in a different grade, if he randomly 50 boys in the school then what if half didn't even play anything. If he did friend what if most friends don't even play a instrument.

Then which one would it be it would be more easier if he did 50 random sixth-graders because they might know friends or themselves and a person who plays an instrument.

Hope this helps

If p varies directly with T and p =105 when T=400.Find p when T =500
kumpel [21]

Answer:

<h3>p = 131.25</h3>

Step-by-step explanation:

The variation p varies directly with T is written as

p = kT

where k is the constant of proportionality

To find p when T =500 we must first find the formula for the variation

That's

when p = 105 and T = 400

105 = 400k

Divide both sides by 400

<h3>k =  \frac{21}{80}</h3>

So the formula for the variation is

<h2>p =  \frac{21}{80} T</h2>

when

T = 500

Substitute it into the above formula

That's

p =  \frac{21}{80}  \times 500

Simplify

The final answer is

<h3>p = 131.25</h3>

Hope this helps you
