Answer:

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

r=\frac{SSxy}{\sqrt{(SSxx)(SSyy)}}

To find SSxy

SSxy= ∑xy- ∑\frac{(x)(y)}{n}

To find SSxx

SSxy= ∑x^{2}- (∑x)^{2}/n

To find SSyy

SSxy= ∑y^{2}- (∑y)^{2}/n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.

Twice x, plus 7, is the same as – 10.<br> The answer is N
sergij07 [2.7K]

Answer:

x=-8.5.

Step-by-step explanation:

First, write an equation. Twice x (2x) plus 7 (+7) is the same as (=) negative ten (-10), or 2x+7=-10. To solve, first subtract 7 from both sides to get 2x=-17. Then, divide both sides by 2 (x=-8.5).

So say we have the number: 54,321

The 5 would be worth 50,000 meaning it's in the ten thousands place.

The 4 would be worth 4,000 meaning it's in the thousands place.

.

The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

.

Hope that helps :)
