No it should be a 50% chance because the first roll is a independent variable, 6/12=1/2

The lengths of the sides of a rectangle are 18cm by 3m. Express the area of the rectangle in square decametres.

lubasha [3.4K]

For this case we have that by definition, the area of a rectangle is given by:

$A = b * h$

Where:

b: It is the base of the rectangle

h: It is the height of the rectangle

By definition we have to:

1 meter equals 0.1 decameters

1 centimeter equals 0.001 decameters

According to the data of the statement we have:

$b = 18 \ cm * \frac {0.001} {1} * \frac {decametres.} {cm} = 0.018 \ decameters.\\h = 3m * \frac {0.1} {1} * \frac {decameters} {m} = 0.3 \ decameters.$

Thus, the area of the rectangle is:

$A = 0.018 * 0.3 = 0.0054 \ decameters ^ 2$

Answer:

$0.0054 \ decameters ^ 2$

Answer:

Answer B $(-\infty,1)U(1,2]$

Step-by-step explanation:

Notice that the quotient of f(x)/g(x) is:

$h(x)=\frac{\sqrt{2-x} }{x-1}$

therefore, this new function imposes conditions due to the fact that it has a square root in the numerator and a binomial in the denominator both with the variable x. Then, in order for the root in the numerator to be defined, the argument inside the root must be larger than or equal to zero. That is:

$2-x\geq 0\\2\geq x\\x\leq 2$

So, this condition must be satisfied by the x-values of the domain.

Then we have the binomial in the denominator, which in order to be defined needs to be different from zero. Notice that the only x-value that could cause problems (render zero) is:

$x-1=0\\x=1$
