Answer:
Inferential statistics
Step-by-step explanation:
When we conduct a poll, we aim to make a generalization about the population or units under study. The recent poll of 1971 home owners in West Virginia showed that the average (mean) price of house <em>in the U.S</em><em>.</em> is $319,000.
Recall that this poll was conducted only in West Virginia but the result or finding of the poll is being generalized over the U.S. as a whole. Hence, we are using the sample (fraction) to determine the population (whole) of home owners in the U.S. This is what we call <em>statistical inference or inferential statistics.</em>
Answer:
The numbers are 87 and 106
Step-by-step explanation:
x + y = 193
x - y = 19
Add y to both sides of the equation
x = 19 + y
Substitute new value for x into first equation
19 + y + y = 193
Add y's together
19 + 2y = 193
Subtract 19 from both sides of the equation
2y = 174
Divide both sides of the equation by 2
y = 87
193 - 87 = 106
The numbers are 87 and 106
