A patient's total surgery charges are $1,278. The patient must pay the annual deductible of $1,000, and the policy states a 80-2

musickatia [10]

Answer:

The patient owe $1255.6 .

Step-by-step explanation:

As given

A patient's total surgery charges are $1,278.

The patient must pay the annual deductible of $1,000.

The policy states a 80-20 coinsurance. (i.e 20% of the surgery amount is given by the patient .)

20% is written in the decimal form .

$= \frac{20}{100}$

= 0.20

20% of patients surgery cost = 0.20 × $1278

= $ 255.6

Patients owe = Deductible cost + 20% of patients surgery cost

= $1000 + $255.6

= $ 1255.6

Therefore the patient owe $1255.6 .

3 & 4, And tell explanation<br><br> (P.S: Sorry for my sloppy handwriting)

Kazeer [188]

3) Altitude / Time = y2 - y1 / x2 - x1 = 30 - 60 / 6 - 3
m = -30 / 3
m = -10

In short, constant rate of change is y = -10x

b) Constant proportionality exists between two quantities, as the amount of changing in Altitude over fixed period of time is same (constant) for every instance.

4) Sales / Day = y2-y1 / x2-x1 = 2,000 - 1,000 / 6 - 3
m = 1000 / 3
m = 333.3

a) In short, Constant relationship is y = 333.3x

b) Constant proportionality exists between two quantities, as the amount of changing in Sales over fixed days is same (constant) for every instance.

Hope this helps!

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The

oksian1 [2.3K]

Answer:

b=-a

Step-by-step explanation:

we know that b is located the same distance from 0 as another number, a, but in the opposite direction.

so the sum of the two numbers equal zero

a+b=0

a=-b or b=-a
