Ateacher is assessing the correlation between the number of hours spent studying and the average score on a science test. the table shows the data:

number of hours spent studying
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4
score on science test
(y) 57 62 67 72 77 82 87 92 97

part a: is there any correlation between the number of hours students spent studying and the score on the science test? justify your answer. (4 points)

part b: write a function that best fits the data. (3 points)

part c: what does the slope and y-intercept of the plot indicate? (3 points)

What scale factor was applied to the first rectangle to get the resulting image interior answer as a decimal in the box

This is a map of the mars exploration rover opportunity predicted landing site on mars. the scale is 1cm : 9.4km. what are the approximate measures of the actual length and width of the ellipse? i mostly need to know how to set it up : )

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
