So, if I'm understanding you correctly, f(x)=x^2 divided by 3x+x, or
f(x) = (x^2)/(3x+x)
f(6) --> plug the 6 in to all values of x --> f(6) = (6^2)/(3×6 + 6) = 36/(18+6)
= 36/24 --> both are divisible by 12, so 36/12=3 and 24/12=2, now we have the reduced (simplified) answer:
f(6) = 3/2, or 1 1/2, or 1.5
Step-by-step explanation:
Population Mean (u) = 3.50
Sample (n)= 36
Sample mean (x) = 3.60
Population standard deviation (s)= 0.40
Test statistics:
(Null hypothesis) H0: u= 3.5 (Population mean is equal to 3.5)
(Alternate hypothesis) H1: u> 3.5 (Population mean is greater than 3.5)
Z=
=
=
= 1.5
critical value= Z0.05= 1.645 (From Z table)
Since, Z value is less than critical Z value that is Z<1.645
We cannot reject null hypothesis
So, we decide to reject that the mean GPA of graduates exceeds 3.50
Answer:
10w2+9w-2
10*w*2+(9*w)-2
10*3*2+(9*3)-2
60+27-2
=85
Step-by-step explanation:
Well, product means multiply so we need to multiply these fractions.
2 4
--- x --- =
3 5
now, when you are multipliying fractions you multiply the top and the bottom with the other one.
so 2 times 4 and 3 times 5
and you get
8
--
15
since this fraction can not be simplifyed this is the final answer 8/15
