Answer:

x = -3.

Step-by-step explanation:

First we need to simplify it to where we can have x on only one side, an everything else on the other. Subtract 2x from the left side and right side to get 2=x+5. Next to get x alone, subtract 5 from both sides. ( 2-5=x+5-5) We now have X = -3.

Hope this is helpful.

Edit: Almost forgot the negative at the top, sorry.

The sum of the squares of two consecutive positive even integers is 52.Find the integers
ankoles [38]

Answer:

The two consecutive positive integers are 4 and 6.

Step-by-step explanation:

Let x be an even integer, then the next even integer is (x+2).


The sum of the squares of these even integers is 52.


We can write the following equation and solve for x.


x^2+(x+2)^2=52.

We expand to get,

x^2+x^2+4x+4=52.

We simplify to get,

2x^2+4x+4-52=0.


This gives us,

2x^2+4x-48=0


We divide through by 2 to get,

x^2+2x-24=0.

This is now a quadratic trinomial

We split the middle term to get,


x^2+6x-4x-24=0.


We factor to obtain,

x(x+6)-4(x+6)=0


\Rightarrow (x+6)(x-4)=0


\Rightarrow (x+6)=0 or (x-4)=0


\Rightarrow x=-6 or x=4


We discard x=-6 since it is not a positive integer.

\therefore x=4


Hence the two consecutive positive even integers are,

4

and

4+2=6

For an analysis of variance, if the between-group estimate of the population variance is 30, and the within-group estimate is 25
borishaifa [10]

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 =\frac{30}{25}=1.2

So for the given variance F ratio will be 1.2
