<span>The hundredth place is the one with two places to the right of the decimal place. For example in the number 123.4579, five is in the hundredths place.
Therefore, the answer 3.88 + 4.82 + 1.73 correctly shows rounding to the hundredths place. All of the numbers being added together only have two numbers after the decimal. By laws of math, when they are all added together, there will only be two number after the decimal.</span>
Answer:
C.
Steps:
Using points (1,0) and (0,3), you can find the slope.
3 - 0 = 3
1 - 0 = 1
3/1 = 3
To do that you'll need the mean and standard deviation of all the scores. Can you provide this info?
For example: Supposing that the mean of these scores were 52 and the standard deviation 3. You'd need to find the "z-score" of 57 in this case.
57 - 52
It is z = ------------ , or z = 5/3, or z = 1.67.
3
Find the area to the left of z = 1.67. Multiply that area by 100% to find the percentile rank of the score 57.
Answer: C: 12-7x
Step-by-step explanation:
This expression is a good example of the difference of two squares, as 144 is the square of 12, while 49x² is the square of 7x.
Any difference of two squares 
can be factored into the sum of their square roots times the difference of their square roots 
.
Let's factor our expression.
Out of all the options given, only 
is a factor. Hence, option C is correct.
