You must multiply 2.5 by 7 to get the answer which is 17.5 pounds
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 =

/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7

/6
360-3=330 = 11

/6
Lwh = (3+3+6) (4) (7)
12 x 4 x 7 = 336
C.
because a, b, and d aren't porportional
but c x is divided by 2
C
there can be more than one mode. 20 and 30 have the same amount and are most frequent
