Answer:
6? i am soooo confused
Step-by-step explanation:
A. When f(x) becomes g(x) = f(x) + 2, the graph of f(x) is shifted upward 2 units.
B The graph of f(x) is reflected in the x-axis and then vertically compressed by a factor of 1/2.
Answer: |p-72% |≤ 4%
Step-by-step explanation:
Let p be the population proportion.
The absolute inequality about p using an absolute value inequality.:
, where E = margin of error,
= sample proportion
Given: A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .
|p-72% |≤ 4%
⇒ 72% - 4% ≤ p ≤ 72% +4%
⇒ 68% ≤ p ≤ 76%.
i.e. p is most likely to be between 68% and 76% (.
-3(5-6)-4(2-3)
Handling parentheses first:
-3(-1)-4(-1)
Multiplication left to right:
3-4(-1)
3-(-4)
Rewriting the above we have:
3+4=7
