Answer:

D: (-∞, ∞)

R: (-∞, ∞)

Step-by-step explanation:

All linear equations have infinite domains and ranges. This is because they are endless, they keep going on forever and ever. When you graph this function, it's a straight line with no limits. If you decide to plot f(1000000), you will have a definite point where the line touches x=1000000. It will go on forever.

Step-by-step explanation:

P value for the test is the probability of obtaining results that have been observed in the null hypothesis statement. A very small value of p indicates that there is unlikely chance of null hypothesis being true which means that we cannot accept null hypothesis based on the small p value.

Answer:

Length 37 cm, width 25 cm.

Step-by-step explanation:

Let the original dimensions be length x and width x - 12 cms.

The new dimensions will be length (x - 2) and width (x - 12 - 2) = x-14 cm.

So , from the areas, we have:

x(x - 12) - (x - 2)(x - 14) = 120
