First you need to divide 64 by 75 and then multiply by 100 which is 85.3% which then you need to find the average of the 2 which will be (85.3+x)/2=88 where x= the value of the second test.

Then you will need to isolate the x with the following steps:

  1. multiply each side by 2 making it 85.3+x=176
  2. Subtract 85.3 from each side
  3. this results in 90.7

Answer:

90.66.....%

Step-by-step explanation:

let x be the second test score,

0.5( 64/75 + x ) = 0.88

solve for x

x = 0.88 * 2 - 64/75 = 0.906666....

which is equivalent to 90.6666... %

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

-6(t + 2) = 18

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. [Distributive Property] Distribute -6:                                                             -6t - 12 = 18
  2. [Addition Property of Equality] Add 12 on both sides:                                 -6t = 30
  3. [Division Property of Equality] Divide -6 on both sides:                                t = -5

The hospital in patient admission rate for employees of the ramsey
romanna [79]

The computation shows that the the hospital in-patient admission rate for the employees of the Prendergast Corporation is 104.5 admissions per 1000 employees.

<h3>How to calculate the value?</h3>

The in-patient admission rate for Ramsey Manufacturing company = 100 admissions per 1000 employees.

It is given that the in-patient rate of Prendergast will be 10% higher than Ramsey's.

So, in-patient rate of Prendergast:

= 100 + 10% of 100

= 110 admissions

Now, it is also given that out of total in-patients, 5% are for tonsillectomies (which are not in-patient).

So, in-patient admission rate for Prendergast:

= 110 - 5% of 110

= 110 - 5.5

= 104.5 admissions per 1000 employees

The hospital in-patient admission rate for employees of the Ramsey Manufacturing Company is 100 admissions per 1000 employees per year.

The Prendergast Corporation has older employees and is told that its hospital in-patient admission rate will be 10% higher than Ramsey’s. At the same time, however, all tonsillectomies will be done in the hospital’s outpatient department instead of requiring the patient to be admitted as an in-patient. Given that 5% of all in-patient admissions are for tonsillectomies, what is the hospital in-patient admission rate for the employees of the Prendergast Corporation?
