Answer:

There is approximately 5.475 liters of blood in the body.

Step-by-step explanation:

At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.

73 ml in liters = 73\times0.001=0.073 liters

Now, 75 beats/min x  0.073 liters/beat  = 5.475 liters/min

And 5.475 liters/min x 1 min/body = 5.475 liters/body

Hence, there is approximately 5.475 liters of blood in the body.

The statement if TRUE.

There is no restriction on the coefficient of the polynomial, it can either be a fraction,a negative number of a positive number or even irrational number. It does not have any effect.
What matters is the exponent. The exponent must be a non-negative integer. Since in this case the exponent is positive, the expression will be a polynomial.
