kvv77 [185]

Answer:D) 0.6375


Step-by-step explanation:

See, the probability that Kevin would inherit diabetes is 0.75

The accuracy of this test is 0.85

A group of friends go out for lunch. If they order 2 hot dogs and 4 cheeseburgers, the bill will
Trava [24]

Answer:

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

Step-by-step explanation:

Let x = cost of a hot dog

     y = cost of a cheeseburger

(1)      2x + 4y = 23.5           (2)    5x + y = 18.25    

                                                           y =  18.25 - 5x

        2x +4(18.25 - 5x) = 23.5

         2x + 73 - 20x = 23.5

         -18x + 73 = 23.5

                  -18x = -49.5

                       x = 2.75                       y = 18.25 - 5(2.75)

                                                           y = 18.25 - 13.75

                                                           y = 4.50

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger
