Answer:
Three-half
Step-by-step explanation:
The value Three-half cannot represent the probability of an event occurring, because it is greater than one. The probability of something cannot be greater than one.
Answer:
50, 60, 70
Step-by-step explanation:
The mode is the value that appears the most:
2 50s
2 60s
1 80s
2 70s
1 55s
1 85s
1 90s
The modes are 50, 60, and 70
Answer:
E and F
Step-by-step explanation:
I would guess because the shown diagram has a closed line segment, meaning its not A or C because they are ever lasting, B and D is considered a Ray since its going non stop one way, leaving E and F
![\huge{\boxed{14x^3 + 7y^2 - 2}}](https://tex.z-dn.net/?f=%5Chuge%7B%5Cboxed%7B14x%5E3%20%2B%207y%5E2%20-%202%7D%7D)
The like terms can be grouped by their variables and exponents. Let's do that.
![x^3:\ \ \ 4x^3 + 6x^3 - 4x^3](https://tex.z-dn.net/?f=x%5E3%3A%5C%20%5C%20%5C%204x%5E3%20%2B%206x%5E3%20-%204x%5E3)
![y^2:\ \ \ 7y^2](https://tex.z-dn.net/?f=y%5E2%3A%5C%20%5C%20%5C%207y%5E2)
![1^1:\ \ \ \ -1 - 6 + 5](https://tex.z-dn.net/?f=1%5E1%3A%5C%20%5C%20%5C%20%5C%20-1%20-%206%20%2B%205)
Now, just add each group of like terms together by adding their coefficients.
![x^3:\ \ \ 4x^3 + 6x^3 - 4x^3\ \ \ \bf{=14x^3}](https://tex.z-dn.net/?f=x%5E3%3A%5C%20%5C%20%5C%204x%5E3%20%2B%206x%5E3%20-%204x%5E3%5C%20%5C%20%5C%20%5Cbf%7B%3D14x%5E3%7D)
![y^2:\ \ \ 7y^2\ \ \ \bf{=7y^2}](https://tex.z-dn.net/?f=y%5E2%3A%5C%20%5C%20%5C%207y%5E2%5C%20%5C%20%5C%20%5Cbf%7B%3D7y%5E2%7D)
![1^1:\ \ \ \ -1 - 6 + 5\ \ \ \bf{=-2}](https://tex.z-dn.net/?f=1%5E1%3A%5C%20%5C%20%5C%20%5C%20-1%20-%206%20%2B%205%5C%20%5C%20%5C%20%5Cbf%7B%3D-2%7D)
Now, add all the terms together. ![\boxed{14x^3 + 7y^2 - 2}](https://tex.z-dn.net/?f=%5Cboxed%7B14x%5E3%20%2B%207y%5E2%20-%202%7D)
