Jack plotted the graph below to show the relationship between the temperature of his city and the number of ice cream cones he sold daily: Main title on graph is Ice Cream Cone Sale. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 60 on y axis at increments of 10. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Ice Cream Cones Sold. Dots are made at the ordered pairs 0, 5 and 5, 15 and 7.5, 15 and 10, 24 and 10, 28 and 12, 32 and 12.5, 25 and 12.5, 30 and 15, 35 and 15, 40 and 17.5, 35 and 20, 45 and 22.5, 36 and 23, 46 and 25, 55 and 27.5, 60.
Part A: In your own words, describe the relationship between the temperature of the city and the number of ice cream cones sold. (5 points)

Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

a is the answer to ur question
