What is a square root and what does it do?
WINSTONCH [101]

Answer:

Hey

Definition:-

A square root is a number which produces a specific quantity when multiplied by itself.

Example:-

Suppose the area of a square of side 6 cm is given by 6 × 6 = 36 cm².

Therefore 36 is said to be the square of 6. We write 6² = 36 and we read the ‘the square root of 6 is 36' or simply ‘6 squared is 36.'

hope this helps

Step-by-step explanation:

Please find the complete question in the attached file.

\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\

        = \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802

\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}

\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\
