Answer:
C
Step-by-step explanation:
Answer: d = 1/3
Step-by-step explanation: 48y = 48/4 = 12. So, 2d(18) is equal to 12. 12/18 is 2/3 so 2d has to equal 2/3. That means d = 1/3.
I have attached the correct answer. Brainliest will be much appreciated!
Answer:
r = 5
Step-by-step explanation:
To solve for r, plug in the change in x values and change in y values, since the hypotenuse is simply the diagonal of both the y-coordinate and x-coordinates shown via drawing legs on the vertical and horizontal axis. So, since (0,0) is the initial point, r = sqr[(-4-0)^2 + (-3-0)^2 = sqr(16 + 9) = 5.
Now, the angle theta is the angle in which the sine, cosine, and tangent ratios are found. Simply use opposite over hypotenuse for sine, adjacent over hypotenuse for cosine, and opposite over adjacent for tangent using theta as the angle in which these values are obtained.
Answer:
Parameter
Step-by-step explanation:
Parameter and statistic:
- Parameter is a numerical value that describes a population.
- A sample is a part of the population and always smaller than the population.
- The statistic is a numerical value that describes a sample.
Population of interest:
College students aged 18 to 22
Parameter:
66.4% reported using alcohol within the past month
Thus, the given is a parameter as it describes a population proportion.
