A) What is the probability of a positive test, given that the patient has breast cancer? 73.6% B) What is the formal term used to describe this probability measure? C) What is the probability of a negative test, given that the patient is breast cancer free? 98.1% D) What is the formal term used to describe this probability measure? 7. Suppose the following represents the scores for a group of participants on the Geriatric Depression Scale (GDS) involved in a study relating depression to early onset of senile dementia. GDS Score 1 12 16 3 13 16 3 13 17 3 13 18 6 14 18 9 14 21 10 15 22 11 15 22 12 16 22 A) Describe the shape of the histogram with reference to its central location, spread, skew, and kurtosis.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

no he doesnt because "-16' is negatiive
