Answer:
The anwser is A
Step-by-step explanation:
When solving a quadratic equation you always use the first coefficient to divide the equation.
Answer:
Domain is all real numbers. Range is [36- negative infinity]
Step-by-step explanation:
y = 2kx², where k is a real constant.
We have:
2k(1)² - 2k(3)² = 32 or 2k(3)² - 2k(1)² = 32.
=> 2k - 18k = 32 or 18k - 2k = 32
=> -16k = 32 or 16k = 32
=> k = -2 or k = 2.
When x = -2,
y = 2(-2)(-2)² or y = 2(2)(-2)².
=> y = -16 or y = 16.
The required probability that a patient had surgery and experienced a major improvement 31% and that a patient received nonsurgical treatment 14.5%.
<h3>What is probability?</h3>
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of patients who got surgery = 398,
63% of percent said they had a major improvement in their condition,
= 0.63 * 398 ≈ 250
29% among those who received nonsurgical treatment,
= 0.29 * (803 - 398)
= 0.29 * 405
≈ 117
Now,
The probability that a patient had surgery and experienced a major improvement in his or her condition.
= 250 / 803
= 31%
The probability that a patient received nonsurgical treatment and experienced an improvement in his or her condition.
= 117 / 803
= 14.5%
Thus, the required probability is 31% and 14.5%.

Answer: 110, 35, 70, G, J, F, E, B, A, H, C, D, I
Step-by-step explanation:
8. For number 8, you will be using the exterior angle theorem. The exterior angle theorem states that the exterior angle equals the two angles inside the given triangle. Since we have 50 and 60, you will add 50 + 60 to get 110.
9. In this problem, you shall use the vertical angle theorem. The vertical angle theorem is simply that any angles vertical from one another are congruent. So a will be also 35 degrees.
10. This is an image depicting two lines cut by a transversal, creating multiple congruent angles. With this, you will be using the alternate interior angle theorem. Alternate interior angles are angles on different sides of the transversal but inside both of the lines that were cut into, as shown above. So, b will also equal 70 degrees.
Part B:
1. G
2. J
3. F
4. E
5. B
6. A
7. H
8. C
9. D
10. I
