In a clinical trial of 2165 subjects treated with a certain drug, 21 reported headaches. In a control group of 1718 subjects given a placebo, 23 reported headaches. Denoting the proportion of headaches in the treatment group by pt and denoting the proportion of headaches in the control (placebo) group by pc, the relative risk is pt/pc. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, which is the ratio of the odds in favor of a headache for the treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating StartFraction p Subscript t Baseline divided by (1 minus p Subscript t Baseline )Over p Subscript c Baseline divided by (1 minus p Subscript c Baseline )EndFraction . The relative risk and odds ratios are commonly used in medicine and epidemiological studies. Find the relative risk and odds ratio for the headache data. What do the results suggest about the risk of a headache from the drug treatment?

Write the equation in slope-intercept form. 4x+3y=18Question 7 options:

y=43x+6

y=−34x+184

y=−43x+6

y=4x+6

Answers

Answer:

y = -4/3x + 6

Step-by-step explanation:

1. 3y - 4x + 3y = 18 - 3y

2. 4x = -3y + 18

3. 18 - 4x = -3y + 18 - 18

4. -3/-3y = 4x - 18/3

5. y = -4/3x + 6

How to solve for x in a triangle

Answers

Answer:

Please mark BRAINLIEST!!!!!

Step-by-step explanation:

180-(63+38)=9x-2

9x-2=79

9x=81

x=9

Final answer:

To solve for x in a triangle, you can use known values or relationships among the sides and angles of the triangle. The Pythagorean theorem can help find the hypotenuse in a right triangle. Trigonometric functions can be used to solve for x once the values are known.

Explanation:

To solve for x in a triangle, we need to have known values or relationships among the sides and angles of the triangle. The given equation 0 = tan-¹ (A₂/Ax) can help us find one such relationship. Since this is a right triangle, we can use the Pythagorean theorem (x² + y² = h²) to find the hypotenuse. Once we have known values for the sides and angles of the triangle, we can use trigonometric functions like sine, cosine, and tangent to solve for x.
