Answer:
C. Ratio
True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.
Step-by-step explanation:
We want to know which type of variable represent the weigth and the height. Let's analyze one by one the options given:
A. Ordinal
False since by definition an ordinal variable is "is a categorical variable for which the possible values are ordered". And for this case the height and the weigth are not categorical since represent quantitative data.
B. Nominal
False by definition and ordinal variable is which one that can't be represented by numeric values, and for this case the weight and the height are not example of this definition.
C. Ratio
True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.
D. Interval
False on this scale we don't have a clear definition of the 0. And for this case the heigth and the weight have a known definition of the 0 corresponding to the absence of mass. And since the ratios are meaingful for the heigth and the weigth then can't be an interval variable.
I’m pretty sure the answer would be A because the 5 makes the 9 round up to ten and then the 7 becomes an 8.
Answer:
The three iron rods cannot be placed together to form a triangle.
Step-by-step explanation:
We have been given that James has three iron rods. Rod A is 3 feet long, rod B is 8 feet long, and rod C is 13 feet long. We are asked to determine whether the lengths of all rods can be used to form a triangle.
We will use triangle inequality theorem to solve our given problem.
Triangle inequality theorem states that sum of two sides of a triangle must be greater than 3rd side.
Using triangle inequality theorem, we will get inequalities as:
We can see that our 2nd inequality is not true because 11 is not greater than 13.
Since sum of two sides is not greater than 3rd side, therefore, the three iron rods cannot be placed together to form a triangle.
Answer:
i would say the answer is 12

Answer:
45,000 codes
Step-by-step explanation:
We can define that "digits" are defined to symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. There are a total of ten digits.
The problem indicates that the first digit cannot be zero, this means that there are 9 options in the first digit of the code.
For the second, third and fourth digits of the code there is no restriction, so there are 10 options for each.
For the fifth digit of the code, we can choose any even digit, so we have 5 options.
This means that there is a total of
9 * 10 * 10 * 10 * 5 = 45,000
