Solve for x. Round to the nearest tenth, if necessary.
Answer:
x ≈ 2.8
Step-by-step explanation:
using the sine ratio in the right triangle
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{UV}{UW}[/tex] = [tex]\frac{2.4}{x}[/tex] ( multiply both sides by x )
x × sin60° = 2.4 ( divide both sides by sin60° )
x = [tex]\frac{2.4}{sin60}[/tex] ≈ 2.8 ( to the nearest tenth )

When is minimal deception considered ethical in research? Select one
A. When you need to put limits on the study
B. Only when you have a control group
C. When there is no other way to achieve a specific research goal
D. Deception of any kind is never allowed
Option C is correct. When there is no other way to achieve a specific research goal minimal deception considered ethical in research.
When there is no other way to achieve a specific research goal. Minimal deception is considered ethical in research only when it is necessary to achieve a specific research goal, and there is no other way to achieve that goal without using deception. In these cases, the use of deception should be justified and minimized as much as possible.
Researchers should consider the potential harm to participants, and carefully weigh the potential benefits of the research against any potential harm.
Additionally, the use of deception should be disclosed to participants as soon as possible after the completion of the study, so that they can understand what has occurred and why. Overall, researchers should strive to be transparent and to minimize the use of deception whenever possible, and to use it only when it is necessary to achieve a specific research goal that cannot be accomplished through other means.

Calculating a binomial probability PROBLEM: When rolling two fair six-sided dice, getting a pair of ls is called "snake eyes." The probability of getting "snake eyes" on any roll is 1/36. Suppose that a game player rolls the two dice 80 times. Let X = the number of rolls that result in "snake cyes." Find P(X = 2). Interpret this value in context If two dice are rolled 80 times, then there is a 27.089% chance that we get a pair of snake eyes. Question 3 (25 points) Calculating a binomial probability PROBLEM: See the preceding alternate example. Should the player be surprised if fewer than 2 of the rolls result in snake eyes? Calculate an appropriate probability to support your answer.
No, if less than two of the rolls produce snake eyes, the player shouldn't be startled. Out of 80 rolls, there is a 97.78% probability of receiving fewer than two snake eyes, making this scenario highly probable.
P(X < 2) = 1 - P(X = 2) = 1 - 0.27089 = 0.97711
No, if less than two of the rolls produce snake eyes, the player shouldn't be startled. There is a 1/36 chance of receiving "snake eyes" on any roll. Accordingly, the likelihood of receiving two snake eyes out of 80 rolls is only 0.27089, or roughly 27%. The likelihood of receiving fewer than two snake eyes, on the other hand, is 0.97711, or roughly 97.78%, out of 80 rolls. As a result, statistically speaking, it is more likely that less than 2 of the rolls will produce snake eyes. The player shouldn't be shocked if less than two of the dice produce snake eyes.

Based on the data you provided, the proportion of chipped vae in the last 20 produced was 2/20 = 0.1.
Therefore, we would expect the number of chipped vae in the next 10 to be approximately 0.1 * 10 = 1.
Estimating Chipped Vae CountThe estimate of the number of chipped vae in the next 10 was determined by multiplying the proportion of chipped vae in the last 20 produced (0.1) by the number of vae to be produced in the next 10.
0.1 * 10 = 1
This estimate assumes that the proportion of chipped vae in the next production batch is the same as the proportion in the last 20. This is known as a point estimate and it's based on the information we have available.
Keep in mind that this is just a rough estimate and actual results may vary. Other factors such as changes in production processes or quality control measures may affect the proportion of chipped vae in the next batch.

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took.
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in meters (m) and time is in seconds (s), so the units will be in meters per second (m/s).
The formula speed = distance ÷ time can be rearranged, just like any other equation.

if f(5) = 14, f ' is continuous, and 6 f '(x) dx 5 = 19, what is the value of f(6)? f(6) =
The function calculation can be used to determine the value of f(6): f(6) = f(5) + 6 f '(x) (x) dx 5 f(6) = 14 + 6 f '(x) (x) dx 5 f(6) = 14 + 19 f(6) = 33
The values of f(5) and 6 f '(x) dx 5 can be used to get the value of f(6). Since f' is a continuous function by definition, it may be used to determine the area under the curve between any two locations using its derivative. The area between x=5 and x=6 can therefore be calculated using the definite integral 6 f' (x) dx 5. Adding the f value, which is equal to f(5), gives us f. (6). The definite integral 6 f' (x) dx 5 is 19 in this instance, while the value of f(5) is 14. Therefore, f(6) = f(5) + 6 f '(x) dx 5 = 14 + 19 = 33 can be used to compute the value of f(6). This demonstrates that f(6) has a value of 33.

A driveway has a grade of 20%. What’s the slope of this driveway?
Answer:
The slope of the driveway is 0.2 or 20%.
Step-by-step explanation:
Grade is a measure of the steepness of a slope, typically expressed as a percentage. To convert a grade percentage to a slope, you can use the following formula:
Slope = Grade / 100
So in this case, the grade of the driveway is 20%, and using the formula above, the slope of the driveway would be:
Slope = 20 / 100 = 0.2 or 20%
Keep in mind that grade is an expression of the steepness of a slope, and slope is an expression of the incline of a line. They are related, but they are not the same thing. Grade is a percentage, while slope is a ratio, and they are used in different contexts.
In mathematics, the grade of a surface represents its steepness or incline. A driveway with a grade of 20% means it inclines or descends 20 units vertically for every 100 units horizontally. Therefore, the slope of this driveway is 20/100 or 0.2.
Explanation:In the field of mathematics, particularly in geometry, the term grade is often used to express the steepness or incline of a surface, like a driveway. If a driveway has a grade of 20%, it means that for every 100 units you move horizontally, you'll ascend or descend 20 units vertically.
The slope of the driveway is represented by the same proportion: rise over run, or vertical change over horizontal change. Therefore, in this case, the slope of the driveway is 20/100 or 0.2 when expressed as a decimal.
So, a driveway with a 20% grade has a slope of 0.2.

Write the equation for g(x).
After translations function of g becomes g(x)=x²-1.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
The given function is f(x)=x².
When the shape is moved up by k units, then replace y with y + k.
When the shape is moved towards the left by k units, then replace x with x - k.
From the graph, we can see graph of function g is shifted 1 unit up and 2 units left.
