There are three outcomes of 4 out of eighteen outcomes, so the fraction of angle of spinner numbered 4 is
Answer:
Yes
Step-by-step explanation:
Her answer makes sense because 1800 ÷ 9 is 20
Answer:
5% I think
Step-by-step explanation:
Its mostly just a guess but I think its 5%
Refer to the diagram below.
Because ray NP bisects ∠MNQ, therefore
∠MNP = ∠PNQ = 2x + 1.
Therefore
∠MNQ = 2*∠PNQ = 2(2x + 1) = 4x + 2.
Because ∠MNQ is given as x² - 10, therefore
x² - 10 = 4x + 2
x² - 4x - 12 = 0
(x + 2 )(x - 6) = 0
x = -2, or x = 6
When x = -2,
∠MNQ = 4*(-2) + 2 = -6°
This answer is not acceptablle, therefore x = -2 should be rejected.
When x = 6,
∠MNQ = 4*6 + 2 = 26°
Answer: x = 6, and ∠MNQ = 26°
Answer:
B
Step-by-step explanation:
- Parabola that is opening upward has the form

- Parabola opening downward has the form

- Parabola opening leftward has the form

- Parabola opening rightward has the form

Where a is a constant
Now, looking at the graph given, it takes the form 
Where a is 3 (matching the answer).
Hence, B is the correct answer choice.
