A weather historian gathered data from several years about the average temperature and total rainfall in her city during the month of May and organized the data into this table. 58

She used a graphing tool to display the data in a scatter plot, with x representing the temperature and y representing the inches of rain. Then she found the equation of the line of best fit
y = -0.424x + 31637
Based on the line of best fit, approximately how many inches of rain will fall in May if the average temperature is 48°F?

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

the answer is two. hope this !

1. sometimes

2.   never

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
