Answer: 0.137.
Step-by-step explanation:
Let p be the population proportion of musicians that are left-handed.
Given: Sample size : n= 2690 [subset of population]
Number of musicians that are left-handed: x= 368
Then the sample proportion: ![\hat{p}=\dfrac{368}{2690}\approx0.137](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7B368%7D%7B2690%7D%5Capprox0.137)
Since sample proportion is the best point estimate of the population proportion.
Hence, a point estimate for p, the population proportion of musicians that are left-handed is 0.137.
The formula of the perimeter of a rectangle is equal to:
Perimeter = 2L + 2W
Forming the equation.
<span>Perimeter = 2L + 2W
</span>17.6 = 2L + 2W
Getting the lengths.
<span>17.6 = 2L + 2W
</span>2L = 17.6 - 2W
L = (17.6 - 2W) / 2
<span>17.6 = 2L + 2W
</span>2W = 17.6 - 2L
<span>W = (17.6 - 2L) / 2</span>
Answer choice B. It's the only one with a right angle (90 degrees) which is the only way to form a right triangle
A=l*b
=45.25*22.63
=1024.0075
b is approx 22.63
