Write an absolute value function f(t) to describe an individual variance from normal body temperature where t is the individual current temperature

Suppose the relationship between Y and X is given by: Y = 25 - 3X + error  By how much does the expected value of Y change if X decreases by 2 units?

Give the correct notation for the quantity described and compute its value.(a) Proportion of Reese’s Pieces that are orange.  In a bag of 80 Reese’s Pieces, 34 were orange.(b) Average attendance for home games played by the New York Yankees in 2018.  There were 81 home games and the total attendance was 3,483,000.

Mean Temperature (°C) The following scatterplot shows the mean annual carbon dioxide (CO,) in parts per million (ppm) d) What is the meaning of the slope of this equation? measured at the top of a mountain and the mean annual air temperature over both land and sea across the globe, in degrees Celsius (C). Complete parts a through h on the right. O A. For every degree that the mean temperature increases, CO, levels increase by 0.004 ppm. 16.800 O B. For every 0.004 ppm increase in CO, levels, the mean temperature increases by 1°C. 16.725 OC. For every 1 ppm increase in CO, levels, the mean temperature increases by 0.004°C. 16.650 O D.
