Answer:
The two consecutive positive integers are
and
.
Step-by-step explanation:
Let
be an even integer, then the next even integer is
.
The sum of the squares of these even integers is
.
We can write the following equation and solve for
.
.
We expand to get,
.
We simplify to get,
.
This gives us,

We divide through by 2 to get,
.
This is now a quadratic trinomial
We split the middle term to get,
.
We factor to obtain,




We discard
since it is not a positive integer.

Hence the two consecutive positive even integers are,

and

You would have to subtract 13 from 36 to find the amount of females.

there must be 23 females
23:13 is the ratio
Answer:
1.2
Step-by-step explanation:
We have given the variance between - group estimate is = 30
And the variance within - group estimate is =25
Now we have to calculate the F ratio
F ratio is defined as the ratio of variance between the group and variance within the group
So F ratio 
So for the given variance F ratio will be 1.2
Answer:
