Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate for the data below.
ira [324]

Answer:

The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.

That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.

Step-by-step explanation:

The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point.

Our variable is numerical but we have a starting point defined so it can't be an interval variable.

The nominal level of measurement is most appropriate because the data cannot be ordered.

False on this case the bolume can't be a nominal variable since we don't have a categorical variable.

The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.

False we don't have ordered relationship among the variable’s observations

The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.

That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.

McDonald had a farm with a certain number of orange trees. he had to cut down 5 trees to control the insects. Each of the remain
aleksley [76]
(5x210)+41,790= 42,840 initially

Okay so
5 tree cut down
So now he have 41 790 orange so he have less that initially
We have to found how many he had before the 5 tree were cut down
And don't forget that each tree produces 210 oranges
So you look for how many orange he had lost (5x210)
And then addition what you have with 41,790

I hope you understand

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? Wr
Pie

Answer:

\frac{1}{18}

Step-by-step explanation:

As the six-sided number cube had six sides, there are six events which could occur. There is only one interger less than 2 (1), therefore the probability of rolling a number less than 2 is \frac{1}{6}.

There are two events which could occur when flipping a coin. This means the probability of flipping heads is \frac{1}{2}.

To find the probability of both of these happening, you must multiply the fractions together by multiplying together both the denominators and numerators, therefore:

\frac{1}{6} ×  \frac{1}{2} = \frac{1}{18}
