Luis’ sample would be the most random, because not everyone in the cafeteria might check out books from the library, but since everyone Samantha surveyed was in the library already, most of the people she surveyed would be more consistent in their responses.

Which statement best describes a method that can be used to sketch the graph. y = |x - 2| a. Translate the graph of y = |x| two
ser-zykov [4K]

f(x) + n - translate the graph of f(x) n units up

f(x) - n - translate the graph of f(x) n units down

f(x + n) - translate the graph of f(x) n units left

f(x - n) - translate the graph of f(x) n units right

--------------------------------------------------------------------------

We have

y = |x - 2|

f(x) = |x| → f(x - 2) = |x - 2|

<h3>Answer: c. Translate the graph of y = |x| two units right.</h3>

10. The fraction 325/790 converted to a decimal and rounded to the nearest hundredths place is _____
Romashka [77]

Answer: 325/790 rounded to the nearest hundredths place is <em>0.41</em>

Step-by-step explanation:

if you divide 325/790 you get 0.411 and some other numbers. We only need to focus on these 3 numbers. 4 is the tenths place value and the first 1 is in the hundredths place value. Sense the second 1 (which is in the thousandths place value) is less than 5, we don't round the 1 in the hundredths place value up. Meaning your answer is 0.411.

Hopefully this makes sense.
