The percent of error can be found by dividing the difference in weights by the predicted weight.
290 - 258 = 32 pounds
32/258 = 0.124
0.124 = 12.4% approximately was the percent of error
Answer:
3y² -2y -1 =0
Step-by-step explanation:
X= y²+1 .....(1)
3x - 2y = 4.....(2)
put x in (2) : 3(y²+1
)-2y =4
3y² +3 -2y -4 = 0
3y² -2y -1 =0
