hope this is what its asking
City A: mean = 4 City B: Mean = 5
City A: MAD = 1.2 City B: MAD = 1.2
City A: median = 4 CityB: Median = 6
Answer:
The polynomial <u>has a degree of 3</u> because the leading term is -8x³.
Step-by-step explanation:
<h2>Definitions:</h2>
- A <u>term</u> is the product of a number and one or more variables raised to an exponent.
- The <u>degree of a term</u> pertains to the exponent of a variable in a term.
- The <u>degree of a polynomial</u> is the highest exponent in a polynomial. Regardless of the value or sign of its coefficient, what matters is the the <u>exponent</u> of the variable.
- The term that has the greatest exponent in a polynomial is referred to as the <u>leading term</u>; the coefficient in a leading term is known as the <u>leading coefficient</u>.
<h2>Explanation:</h2>
Given the following polynomial: 3⁴- 8x³+ 6x²- 3x:
If we rearrange this in descending degree, it will be easier to understand why the given polynomial has a degree of 3:
3⁴- 8x³+ 6x²- 3x ⇒ - 8x³+ 6x²- 3x + 3⁴
"3⁴" is not a term. It is referred to as a constant. 3⁴ = 3 × 3 × 3 × 3 = 81.
We can substute 3⁴ = 81 into the polynomial:
- 8x³+ 6x²- 3x + 81
As we can see, the term with the highest degree is -8x³. Therefore, the polynomial <u>has a degree of 3</u>.
We know that class starts 11:25 AM (be sure to note that there are only 60 minutes in an hour).
We know that class lasts 30 minutes.
First of all, let's find the time class ends.
11:25 AM (class starts) + 00:30 (minutes) = 11:55 AM (class ends)
Let's start with Yul's time first.
We know that Yul left when class was done, the time was already calculated when we added the time the class started with the time the class lasted and we got (in the previous line) 11:55 AM was when class ended, therefore, Yul left at 11:55 AM.
Sarah stayed an extra 5 minutes.
Class ended 11:55 AM. Simply add 5 minutes (00:05) to 11:55 AM.
11:55 AM (time class ended) + 00:05 (extra time to talk with the teacher) = 12:00 PM. Therefore, Sarah left at 12:00 PM.
As stated in the beginning of this problem, each hour only lasts 60 minutes, not 100 minutes, so every time the minutes are at the 60 tick mark, a new hour starts (in this case, 12:00 PM).
Yul left at 11:55 AM.
Sarah left at 12:00 PM.
