Answer:

67.20\%

Step-by-step explanation:

Given

n =2430 --- sample

r = 16.72\% --- degeneration rate

From the findings, we have:

p = 377 --- tested positive

t =561 --- total test

Required

The positive predicted value (PPV)

This is calculated using:

PPV=\frac{Positive}{Total}

i.e.

PPV = \frac{377}{561}

PPV = 0.6720

Express as percentage

PPV = 0.6720 * 100\%

PPV = 67.20

aivan3 [116]

Combine like terms.

2 {x}^{2}  + 8 {x}^{2}  = 10 {x}^{2}

x + 7x = 8x

4 +  ( - 3) = 1

So, the answer would be

10 {x}^{2}  + 8x + 1
