Where are the inequalities?
Answer:
mean= sum of all observations /no.of observation
mean=45+80+15+10+94/5
mean=244/5
mean=48.8
this is how the calculator gets 48.8
We need to simplify the expression:
Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:
Now,
On simplifying the above expression we get:
So the simplified form of the expression .
Step-by-step explanation:
If f(x)=3x+2and g(x)=x^2-9
find (f-g)(x)
f(x)- g(x) = [3x + 2] - [x^2 - 9]
= -x^2 + 3x + 11
