Answer:

1/4

Step-by-step explanation:

There are 3 even numbers of the 6 numbers on a die.

(1,2,3,4,5,6) are the possible numbers. 2,4,6 are even

P( even number ) = 3/6 = 1/2

P (heads) = 1/2

Since they are independent events, we can multiply the probabilities together

P (even, heads) = 1/2 * 1/2 = 1/4

Currently, the sum of the ages of Yumi, Rana and Victoria is 42 years. Four years ago, the sum of the ages of Rana and Victoria

Setler [38]

Y + R + V = 42
but 4 YEARS AGO : (R-4) +(V-4) = Y

Replace Y in the 1st equation by: (R-4) +(V-4)

(R-4) +(V-4) + R + V = 42

2R - 2V - 8 = 42; 2R -2V = 50, or R+V=25
IF R+V =25 AND Y + R +V = 42, then Y + 25 = 42 and Y =17

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.
