First case:
average of test score =70
number of students =p
total score of 'p' students = ( average of test score)*( number of students)
total score of 'p' students =70p
Second case:
average of test score =92
number of students =n
total score of 'n' students = ( average of test score)*( number of students)
total score of 'n' students =92n
total number of students = p+n
total average score =86
so, total score =86(p+n)
total score = total score of 'p' students +total score of 'n' students

now, we can simplify it



now, we can find p/n

Answer:
The domain of function (m.n)x is same as domain of function m(x).
Step-by-step explanation:
Domain: Any set of input values for which the function is defined and valid.
m(x)=x+5/x-1
Domain of m(x) is x>1 or x<1, x≠1, because if x=1 the function will be undefined.
n(x) = x – 3
Domain of x -3 is -∞<x<∞ i.e all real numbers
(m.n)x = (x+5/x-1)(x-3)
= (x+5)(x-3)/x-1
The Domain of (m.n)x is x<1 or x>1 or x≠1 because the function is undefined for x=1
So, the domain of function (m.n)x is same as domain of function m(x).
Answer:
10 divided by 3 is 5 then you add 8 which will give you 13
Answer:
b
Step-by-step explanation:
i did the math for over an hour and got the same answer 25 times
#10) The original graph has x intercept 0 and y intercept 0. The new graph has x intercept 3 and y intercept -3
So x went up 3 and y went down 3. The answer is H.
#11) Plug in x = 0 and solve. The answer is 48, C.
#12) Use a graphing calculator or online calculator. I got r = 0.778
#13) The only one that is shaded correctly is H.
