Mathematics
1 answer:
abruzzese [7]3 years ago
6 0

Answer:  x=\frac{y+6}{2}

Step-by-step explanation:

12-2x=-2\left(y-x\right)

________________________________

(Expand: -2\left(y-x\right))

=-2y-\left(-2\right)x

=-2y+2x

_________________________________

12-2x=-2y+2x

-2x=-2y+2x-12

-2x-2x=-2y+2x-12-2x

-4x=-2y-12

\frac{-4x}{-4}=-\frac{2y}{-4}-\frac{12}{-4}

__________________________________

(Simplify: \frac{-4x}{-4})

\frac{-4x}{-4}

=\frac{4x}{4}

=x

__________________________________

(Simplify: -\frac{2y}{-4}-\frac{12}{-4})

=\frac{-2y-12}{-4}

-\frac{-2y-12}{4}

\frac{-2y-12}{4}

=-\frac{y+6}{2}

-\left(-\frac{y+6}{2}\right)

=\frac{y+6}{2}

x=\frac{y+6}{2}

Determine whether the quantitative variable is discrete or continuous. Weight of a rock
NemiM [27]

Answer:

Continuous.

Step-by-step explanation:

In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.

Basically, random variables are classified into two (2) main categories and these are;

1. Discrete random variable: a discrete random variable is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

2. Continuous random variable: a continuous random variable is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous random variable.

Hence, the weight of a rock is continuous random variable because it has an infinite number of possible values such as 1kg, 20kg, 10kg, 50kg etc.
