Answer:
x = 1, y = 2
Step-by-step explanation:
Original equations:
Substitute y and solve for x:
Plug in x to solve for y:
x = 1, y = 2
Note: You can also substitute x and solve for y, then plug in y to solve for x. I did not do that here.
Answer:
The side lengths remain the same, and the position of the figure changes.
Step-by-step explanation:
A translation is a slide of a figure. A figure can be slid vertically, horizontally or diagonally.
Think of sliding a game board across a table. The lengths of the sides of the board do not change; the angles formed by the sides of the board do not change; and the way the board is turned does not change. This means the only correct option would be the last one.
Answer:
Population = 75,342 households
Sample = 400 randomly selected households
The percentage who live in a single household unit = Parameter
The average of 2.9 person per household of all households in the city = parameter
The $65,000 median family income of all the households in the city = Parameter
Step-by-step explanation:
The population refers to all the entire elements, observations or subject which fits into a particular study. In the scenario above, the entire household in the city of study. That is, the 75,342 households.
The sample is the subset of the population which is a smaller set of observation meant to be representative of the larger population. The sample here is the 400 randomly selected households.
Parameter differs from statistics in that numerical estimates or calculations obtained from the population is called the parameter while the numerical characteristics derived from the sample is called statistic.
