Question
the equation y = 6.75x models the cost, in dollars, to purchase x pounds of steak
at grocery store 1. this table shows the cost to buy different weights of steak at
grocery store 2.
cost of steak at grocery store 2
weight (pounds)
cost
$15.00
$22.50
$37.50
$67.50
which statement is true?
a the cost of steak at grocery store 1 is $0.75 less per pound than at grocery
store 2
the cost of steak at grocery store 1 is $0.75 more per pound than at grocery
store 2
the cost of steak at grocery store 1 is $0.50 less per pound than at grocery
store 2
d the cost of steak at grocery store 1 is $0.50 more per pound than at grocery
store 2
showing work too

the answer is y = 11.54

hope this : )

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
