Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 5.40 − 0.01x and σ = 0.085. (a) What is the expected change in reaction time for a 1°F increase in temperature? For an 11°F increase in temperature? 1°F increase hr 11°F increase hr (b) What is the expected reaction time when temperature is 190°F? When temperature is 260°F? 190°F hr 260°F hr (c) Suppose five observations are made independently on reaction time, each one for a temperature of 260°F. What is the probability that all five times are between 2.66 and 2.94 hours? (Round your answer to four decimal places.) (d) What is the probability that two independently observed reaction times for temperatures 1° apart are such that the time at the higher temperature exceeds the time at the lower temperature? (Round your answer to four decimal places.)

center (1,3) with radius 6
step-by-step explanation:
we must complete the square to find the center and radius of the circle.
first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.
we now create space between the x and y terms with parenthesis.
we complete the square by taking the middle terms -2x and the -6y - divide each and square them.
we add the squares to both sides.
simplify.
and write the quadratics in factored form.
the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
