Answer:

The time the patient expected to survive after diagnosis is 29 years.

Step-by-step explanation:

It is provided that the mean survival time after diagnosis for a certain disease is 15 years with a standard deviation of 5 years.

That is,

\mu=15\\\sigma=5

An individual's predicted survival time is <em>a</em> = 2.8 standard deviations beyond the mean.

Compute the time the patient expected to survive after diagnosis as follows:

X=\mu+a\sigma

    =15+(2.8\times 5)\\\\=15+14\\\\=29

Thus, the time the patient expected to survive after diagnosis is 29 years.

HELPP 10 POINTS Here's a graph of a linear function. Write the equation that describes that function.
erastova [34]

m = (y2-y1)/(x2-x1)

m = (6-4)/(4-0)

m = 2/4

y = mx + c

6 = (2/4)(4) + c

c = 4

Thus, the equation is y = (2/4)x +4

If f(x)=7x-7 what is f(8)+f(4)
NARA [144]

<u>Given Function is</u>

  • f ( x ) = 7x - 7 ------- eqn ( 1 )

<u>Now , put the value of x = 8 in eqn ( 1 )</u>

  • f ( 8 ) = 7 ( 8 ) - 7
  • f ( 8 ) = 56 - 7
  • f ( 8 ) = 49 ------- eqn ( 2 )

<u>Now , put the value of x = 4 in eqn ( 1 )</u>

  • f ( 4 ) = 7 ( 4 ) - 7
  • f ( 4 ) = 28 - 7
  • f ( 4 ) = 21 ------- eqn ( 3 )
<h3 />

<u>From eqn ( 2 ) nd eqn ( 3 ) we get,</u>

  • f ( 8 ) + f ( 4 )
  • 49 + 21
  • 70

Hope Helps! :)
