The expression 12.3 - (-9.6) simplifies to the addition expression 12.3 + 9.6, which equals 21.9. The answer 21.9 could represent various things in different contexts, such as a sum of money, a distance, or a total number of items.
The expression 12.3 - (-9.6) is a mathematical operation involving two real numbers. The negative sign before the bracket signifies that you will be changing the sign of 9.6, which is negative, making it a positive number; this is due to the fact that subtracting a negative number is equivalent to adding a positive number.
As a result, the equation 12.3 - (-9.6) simplifies to 12.3 + 9.6. When these two numbers are added together, we end up with 21.9. This number might represent a variety of things, depending on the context of the problem. It could, for instance, represent a sum of money, a distance, or a total number of items.

Using the Typing Speed of 60 words per minute, it would take Krista about 8.33 minutes to type a 500-word essay.
This question deals with rate problems, specifically with typing speed. Krista can type 60 words per minute. We know that her essay contains 500 words.
Therefore, to find out how long it will take her to type it, we need to divide the total number of words by her speed. Let's do the calculation:
500 words / 60 words per minute = approximately 8.33 minutes
So, it would take Krista about 8.33 minutes to type her essay.

Hi abycflo! Please read the following :)
We know that the first coordinate location given should always be on the x-axis.
The x-axis is the line you can see that is going horizontal or sideways.
So we know that we have to line up 2 on the x-axis and we immediately know its going to be either B or C.
The y-axis is the line going up or vertically. So on the 3 for the y-axis, we found out that our answer is
C, given from the following coordinates given we can affirmatively say its C.
P.S
Have an Amazing day abycflo! I Hope this Helps and Good Luck!

Sample 2 is a random sample from grades 11 and 12 and consists of the following scores: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.
Choose the following statements that correctly compare the two samples.
Check all that are true.
A). Sample 2 shows 11th and 12th grade students, on average, did better.
B) . Sample 1 has a higher probability than Sample 2.
C). The measure of center is the same for both samples.
D). Sample 1 shows 9th and 10th grade students, on average, did better.
E). Sample 2 has a higher median score than Sample 1.
Answer:
E)- Sample 2 has a higher median score than Sample 1.
Step-by-step explanation:
For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).
We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.
Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.
