Find a least-squares solution of axequalsb by (a) constructing the normal equations for modifyingabove bold x with caret and (b) solving for modifyingabove bold x with caret. aequals[start 3 by 2 matrix 1st row 1st column negative 1 2nd column 3 2nd row 1st column 2 2nd column negative 3 3rd row 1st column negative 1 2nd column 3 endmatrix ], bequals[start 3 by 1 matrix 1st row 1st column 4 2nd row 1st column 3 3rd row 1st column 2 endmatrix ]

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.

mariah is studying the life cycle of the monarch butterfly. she must choose one stage in the cycle to present in science class: egg, caterpillar, chrysalis, or adult. she plans to make her choice randomly using a custom spinner divided into four sections. first, however, she spins the spinner 50 times to see the frequencies it generates.

stage times landed on

egg 10

caterpillar 12

chrysalis 15

adult 13
