Variables are variable and samples are samples. Variables are not samples so the question has no meaning.
Confounding variable.

For younger participants there are changes to the ball ( size, weight, texture, colours) and the basket (E.G large dustbins and hoola hoops tied to the basket are used). For older participants they have longer match times.
No. A discrete variable is one that takes discrete numerical values. But a discrete variable can be ordered while a nominal one cannot. Age, in years, is a discrete variable, and you can say that a 10-year old is younger than a 20-year old who is younger than a 40-year old. Favourite fruit would generate a nominal variable but you cannot say that a banana is more than an apple which, in turn, is more than an orange, etc. (Remember, you are talking only of the nominal values of the fruit - not their price or size or nutritional value or any such characteristic.)
Without a variable to represent David's age, the only possible expression is Mario's age = M.
the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.

Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
An isotopic system with a larger decay constant would be more useful for dating younger rocks. This is because rocks with younger ages have lower amounts of parent isotopes left to decay, so a system with a larger decay constant would provide more precise dating for these samples.

The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.
Most individuals do not approve of early marriage in the United States because we encourage education and job seeking before starting a family. In other cultures marriages are considered a resource for monetary gain and participants are married at younger ages.
