Astudent is assessing the correlation between the number of hours a plant receives sunlight in the height to which it grows. the table shows the data:

number of hours of sunlight (x) :
0 1 2 3 4 5 6 7 8 9
height of plants in cm (y) :
4 7 10 13 16 19 22 25 28 31

part a: is there any correlation between the number of hours of sunlight that a plant receives in the height to which grows?
justify your answer.

part b: write a function that best fits the data.

part c: what does the slope and y intercept of the plot indicate about the plants?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
