y = 255x + 6559

Step-by-step explanation:

Function Modeling

We have the following relationship between the minutes into the ride (x) and the elevation of the tram (y):

x={2,5,9,14}

y={7069,7834,8854,10129}

We first test if the relationship is linear or not.

A linear relationship is tested by calculating the slope from any pair of points.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

Selecting the first two points (2,7069) and (5,7834)

m = 255

Selecting the first two points (5,7834) and (9,8854)

m=255

If we repeat the calculation with any pair of points, we get the same value for the slope, thus we can conclude the relationship is linear.

Using the point-slope form of the line:

y - k = m( x - h )

We select the point (2,7069)

y - 7069 = 255( x- 2 )

Operating:

y - 7069 = 255x - 510

Adding 7069:

y = 255x - 510 + 7069

y = 255x + 6559

answer: x=3 and y=4

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

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
