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

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

how am i supposed to answer

step-by-step explanation:

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
