Answer:

7/12

Step-by-step explanation:

1, 2, 3, 4, 5, 6, and 7, are all possible rolls less than 8. that's seven combos.

Seven out of twelve. That's 7/12. So the probability of rolling a number less than 8 on a 12 sided die is 7/12.

Adam would like to buy a used car, and collected several data to evaluate the best model (such as age, price, weight, etc.) Than

9966 [12]

Answer: There is a strong association between age and weight.

Step-by-step explanation:

The correlation coefficient (r) is used to describe the relationship between two variables.

$-1\leq r\leq1$

If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.

Here, Variables: Age and weight.

correlation coefficient = 0.512

That means, there is a strong association between age and weight.

In the smaller triangle, let $y$ be the length of the smallest leg. Then the smallest leg in the larger triangle is $14-y$ .

Within the scope of the smaller triangle, we have $y$ such that

$x^2+y^2=13^2\implies y=\sqrt{13^2-x^2}$

Then within the larger the triangle, we would have

$x^2+(14-y)^2=15^2\iff x^2+\left(14-\sqrt{13^2-x^2}\right)^2=15^2$

Now we can solve for $x$ :

$x^2+14^2-28\sqrt{13^2-x^2}+(13^2-x^2)=15^2$

$\implies x=12$
