Consider the given data.
x 2 4 6 7 10 11 14 17 20
y 4 5 6 5 8 8 6 9 12
a - find the least-squares fit. derive the least-squares fit of the following model:
y=a1x+e
that is, determine the slope that results in the least-squares fit for a straight line with a zero intercept for the given data. (round the final answer to four decimal places.)

energy can cross the boundaries of a closed system in the form of heat and mass

can you make it more obvious. i can't see it properly

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
