The simplified trigonometric expression in this problem is defined as follows:

sin(3x)/sin²(x) = 3csc(x) - 4sin(x).

The trigonometric expression in this problem is defined as follows:

sin(3x)/sin²(x).

The equivalent expression for the sine of 3x is given as follows:

sin(3x) = 3sin(x) - 4 sin³(x).

Then the expression can be written as follows:

(3sin(x) - 4 sin³(x))/sin²(x)

The subtraction is in the numerator, hence the expression can be simplified as follows:

3sin(x)/sin²(x) - 4sin³(x)/sin²(x)

3/sin(x) - 4sin(x)

One divided by the sine is equivalent to the cossecant, hence:

3/sin(x) - 4sin(x) = 3csc(x) - 4sin(x).

Meaning that the first option among those given on the image at the end of the answer is correct.

The problem is given by the image shown at the end of the answer.

Step-by-step explanation:

Answer:

x = 15

yes

Step-by-step explanation:

17²= 289

8²= 64

A² + B² = C²

8²+ B² = 17²

64 + B² = 289

-64 -64

B²= 225

√225

B = 15

Answer: x = 8, y = 2, coordinates (8,2)

Step-by-step explanation:

2x = 4y + 8 (divide by 2 to get value of x)

x = 2y + 4

(now substitute x into the second equation to find value of y)

2y + 4 - 2y = 4

2y - 2y = 4 - 4 (divide by 2 to get value of y)

y - y = 2 - 2

y = 2

Now plug in value of "y" to get value of "x".

x - 2(2) = 4

x - 4 = 4

x = 8

The relationship between the standard deviation and variance is that the standard deviation is the square root of the variance.

The correct option is -C

Hence, the correct option is (c) Standard deviation is the square root of the variance. Variance is the arithmetic mean of the squared differences from the mean of a set of data. It is a statistical measure that measures the spread of a dataset. The squared difference from the mean value is used to determine the variance of the given data set.

It is represented by the symbol 'σ²'. Standard deviation is the square root of the variance. It is used to calculate how far the data points are from the mean value. It is used to measure the dispersion of a dataset. The symbol 'σ' represents the standard deviation. The formula for standard deviation is:σ = √(Σ(X-M)²/N) Where X is the data point, M is the mean value, and N is the number of data points.

What is simplification?

Exam scores are improved by simplifying mathematical problems, which is also used in everyday life to get discounts in malls of up to 35%, flat discounts, or 20% for purchases up to Rs. 100. In this section, you only need to use the basic simplification principles to solve equations.

Therefore, simplifying an expression entails using various techniques to transform it into a simpler variant. The actions needed to reduce things are carried out in a predetermined sequence known as BODMAS.

To simplify the expression, we can start by distributing the coefficients to the terms inside the parentheses:

3/4(5a - 16) - 1/3(6a - 3)

= (3/4 * 5a) - (3/4 * 16) - (1/3 * 6a) + (1/3 * 3)

= (15/4)a - 12 - 2a + 1

= (15/4)a - 2a - 11

The correct option is option (a). In the last seven presidential elections in the United States, the age group that voted the most six out of seven times was 65 and older.

The age group of 65 and older has consistently shown higher voter turnout compared to other age groups in recent presidential elections in the United States. This trend can be attributed to several factors.

Firstly, older adults generally have higher rates of civic engagement and are more likely to view voting as a crucial responsibility. They may have a greater sense of political efficacy and are motivated to participate in the democratic process.

Additionally, older adults tend to have more stable living situations and established routines, which can make it easier for them to prioritize voting. They may also have more free time and flexibility in their schedules, allowing them to overcome potential barriers to voting, such as long wait times at polling stations.

Furthermore, issues such as Social Security, healthcare, and retirement benefits often directly affect older adults, making them more inclined to participate in elections to protect their interests.

parameterization of the line that passes through the point (2,-3) with a slope of 4 is option D. x= t and y = 4t - 6, for any t

It is a parameterization of the line that passes through the point (2,-3) with a slope of 4, because the point (2,-3) satisfies the equation x = t and y = 4t - 6 and the slope of the line is

A parameterization of a line is a set of equations that describe the location of points on the line in terms of a parameter. One common parameterization of a line is the point-slope form, which expresses the line as y = mx + b, where m is the slope of the line and b is the y-intercept.

Another common parameterization is the two-point form, which expresses the line as (x - x1)/(x2 - x1) = (y - y1)/(y2 - y1), where (x1, y1) and (x2, y2) are two distinct points on the line.

Ron will have to attend 7 weeks of school this quarter before he will have taken a total of 10 quizzes.

The given equation q = w + 3 represents the relationship between the total number of quizzes Ron has ever taken (q) and the number of weeks he has attended school this quarter (w). According to the equation, for each week Ron attends school, he takes one additional quiz.

To find the number of weeks of school Ron needs to attend before he will have taken a total of 10 quizzes, we can substitute the value of q (10) into the equation and solve for w.

10 = w + 3

Subtracting 3 from both sides of the equation, we have:

w = 10 - 3

w = 7

Therefore, Ron will have to attend 7 weeks of school this quarter before he will have taken a total of 10 quizzes.

The probability that a randomly selected junior biology major has taken either a statistics or a computer course is 0.68

To find the probability that a randomly selected junior biology major has taken either a statistics or a computer course (or both), we'll use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

Where:
- P(A) is the probability of having taken a statistics course (52% or 0.52)
- P(B) is the probability of having taken a computer course (23% or 0.23)
- P(A and B) is the probability of having taken both courses (7% or 0.07)

Now, plug in the values:

P(A or B) = 0.52 + 0.23 - 0.07
P(A or B) = 0.68

So, the probability that a randomly selected junior biology major has taken either a statistics or a computer course (or both) is 0.68, or 68%.

Step-by-step explanation:

The solution to the equation is x = 17/30.

To solve the equation, start by combining like terms on both sides.

On the left side, we have the fraction 2/3 and the term -4x.

On the right side, we have the fraction 7/2 and the term -9x.

To combine the fractions, we need a common denominator.

The least common multiple of 3 and 2 is 6.

So, we can rewrite 2/3 as 4/6 and 7/2 as 21/6.

Now, the equation becomes:

4/6 - 4x = 21/6 - 9x

Next, let's get rid of the fractions by multiplying both sides of the equation by 6:

6 * (4/6 - 4x) = 6 * (21/6 - 9x)

This simplifies to:

4 - 24x = 21 - 54x

Now, we can combine the x terms on one side and the constant terms on the other side.

Adding 24x to both sides gives:

4 + 24x - 24x = 21 - 54x + 24x

This simplifies to:

4 = 21 - 30x

Next, subtract 21 from both sides:

4 - 21 = 21 - 30x - 21

This simplifies to:

-17 = -30x

Finally, divide both sides by -30 to solve for x:

-17 / -30 = -30x / -30

This simplifies to:

x = 17/30

So the solution to the equation is x = 17/30.

To solve we need to calculate the z-score, but since we are given the sample size then we shall begin as follows:

The z-score is calculated as (320 - 300)/(50/6) = 2.4, which means that the value of 320 is 2.4 standard deviations above the population mean of 300. Using a standard normal table or calculator, we can find the probability that a standard normal random variable is less than 2.4, which is approximately 0.9918.

This means that the probability that the sample mean is greater than 320 is approximately 0.9918. In other words, there is a 99.18% chance that a randomly selected sample of 36 U.S. Marines will have a mean number of pushups greater than 320.

μ=300, σ=50, n=36, x=320

So,

σ/√n

= 50/√36

= 8.33333

z=(320-300)/8.33333

z=2.4

Therefore,

P(x>320)=P(z<2.4)=0.9918.
