Hello,
Let's assume n,n+1,n+2,n+3,n+4 the 5 numbers
n+(n+1)+...+(n+4)=5n+10=265
5n=265-10
5n=255
n=51
The 5th number is 51+4=55
7 + 2 = 9 and 9/12 + 11/12 = 20/12 = 1 8/12 = 1 2/3
9 + 1 2/3 = 10 2/3
Answer:
f(x)=740
Step-by-step explanation:
f(x)=45x+200
If f(12)
f(x) = 45(12) +200
f(x) = 540 +200
f(x)=740
Answer:
3/10
Step-by-step explanation:
Given:
Standard error = 4
Population standard deviation = 16
To find:
The value of n.
Solution:
The formula of standard error is:
Where, SE is standard error , 
is population standard deviation and n is the total number of elements.
Substituting 
in the above formula, we get
Taking square on both sides, we get
Therefore, the value of n is 16.
