The scatter plot shows the number of strawberries that have been picked on the farm during the month of february:

(a scatter plot with points showing an upward trend with points that are moderately spread out from a line of best fit. the y axis is labeled number of strawberries and the x axis is labeled days in february)

part a: using computer software, a correlation coefficient of r = 0.01 was calculated. based on the scatter plot, is that an accurate value for this data? why or why not? (5 points)

part b: instead of comparing the number of strawberries picked and the day in february, write a scenario that would be a causal relationship for strawberries picked on the farm. (5 points)

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
