Use a graphing calculator or other technology to answer the question. Which quadratic regression equation best fits the data set?

yˆ=32.86x2−379.14x

yˆ=32.86x2+379.14x−1354.14

yˆ=32.86x2−379.14x+1354.14

yˆ=−1354.14x2−379.14x+32.86

Add the cents that add the left overs to get the first number

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
