Tribulus is a food supplement that some athletes use to enhance performance. A study1 on the effects of this supplement involved randomly assigning athletes to take the supplement for a day period and comparing various characteristics to similar athletes who were not given Tribulus. One of the measurements was anaerobic alactic muscular power (AAMP) where the Tribulus group showed a mean performance of with a standard deviation of while the control group had a mean AAMP of with a standard deviation of:.

i think it is

step-by-step explanation:

a formal letter is a letter the you would send to a king

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
