Step-by-step explanation:
Given that;
n=6 , m=2 , z1 is the average of the elements of x , and z2 is the average of the first three elements of x minus the average of fourth through sixth elements of x
So, Let d=n∧28, d′=n∧22.
We have nd=10, nd′=20n
so
n=10d=20d′nwhenced=2d′.
On the other hand, d is a divisor of 28, and above shows d′ is, too. As it is also a divisor of 22, the only possibilities are d′=1, d′=2, corresponding to d=2, d=4.
However, if d=2, n=20, and 20∧28=4, not 2. So the only solution is d=4, and n=40.
Answer:
12
Step-by-step explanation:
3 x 12= 36
36-9= 27
Nothing multiplies into 12 and adds into 17. Factors of 12 are 1,2,3,4,6, and 12. None of those add up to 17.
The general form for this parabola ix x^2 = 4ay where the focus is (0,2)
a = 2 so we have:-
x^2 = 4(2)y
y = (1/8) x^2 is the answer.
