I believe the second one : drawing a number from a hat, not replacing it, and then drawing a second number
Answer:
Volume of emerald = 137.04cm³
Step-by-step explanation:
Given that:
Mass of emerald = 378.24grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 378.24grams / 2.76grams/cm³
Volume of emerald = 137.043cm³ ~137.04cm³
Volume of emerald =137.04cm³
Answer:
A function means that we get one input and one output. In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points. Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
Answer:
3
Step-by-step explanation:
We can see that the graph is constant.=> the path of the dot/ the pattern is constant or not changing.
The balance was 18 when there were no visits.
It was 0 after 6 visits.
=>the amount spent on each visit is
Balance/number of visits= 18/6= $3
This can clearly be seen on the graph.
It may not work with a graph where the patter is not constant/ keeps on changing.
