3 pieces of wood have a total length of 32 m. The second piece is twice the size of the first and the third piece is 2 more mete
andreev551 [17]

Answer:

X + Y + Z = 32

X2 = Y

X3 + 2 = Z

X + X2 + X3 + 2 = 32

Make X alone

There is a 2 so we subtract 2 from both sides

X + X2 + X3 = 30

Add the X's up

X + X2 + X3 = X6

X6 = 30

Divide by 6

30 / 6 = 5

You are left with X=5

The first piece of wood has a length of 5

5 x 2 = 10

The second piece has a value of 10

5 x 3 + 2 = 17

The third piece is 17

Hope this helps. If you have any questions you may ask.

Answer:

Standard deviation of a normal data distribution is a measure of data dispersion.

The value of standard deviation will never be negative.

The greater the spread, the greater the standard deviation.

2.Then find out the square of it's distance to mean value.

3.Then total the values

4.Then divide the number of data point.

5.the square root have to be taken.

Formula-

SD=\sqrt{\frac{(\sum{x-x)^2}  }{n-1}

   Advantage-

It is used to measure dispersion when mean is used as measure of central tendency.
