The insurance company pays the full cost of 3,900 prescriptions claims out of 4,500 prescriptions claims submitted. what is the rate of the claims paid expressed as a percent? (show your work)

To find the rate of the claims paid, simply divide (where x is the rate of the claims paid) :

Since you need it in a percent form, move the decimal two times to the right and add a percent sign (your answer is):

86.67%. Hope I could help!

86.67%.

Step-by-step explanation:

We have been given that the insurance company pays the full cost of 3,900 prescriptions claims out of 4,500 prescriptions claims submitted.  

To solve our given problem, we need to find 3,900 is what percent of 4,500.

Therefore, the rate of the claims paid expressed as a percent would be 86.67%.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
