PLEASE HELP ME ITS DUE SOON IF YOU PUT A LINK OR UNHELPFUL ANSEWR I WILL REPORT YOU I WILL GIVE PLUS 10 POINTS TO THE BRAINLIEST.

30 pts, will mark brainliestwhat is the period of the sinusoidal function? (picture 1)what is the minimum of the sinusoidal function? (picture2)what is the maximum of the sinusoidal function? (picture 3)

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
