Step-by-step explanation:

The correct statement among the given options is A. "Research cannot use both qualitative and quantitative methods in a study."

This statement is not correct because research can indeed use both qualitative and quantitative methods in a study. Qualitative research focuses on collecting and analyzing non-numerical data such as observations, interviews, and textual analysis to understand phenomena in depth. On the other hand, quantitative research involves collecting and analyzing numerical data to derive statistical conclusions and make generalizations.

Many research studies employ a mixed methods approach, which combines both qualitative and quantitative methods, to provide a comprehensive understanding of the research topic. By using both qualitative and quantitative data, researchers can gather rich insights and statistical evidence, allowing for a more comprehensive analysis and interpretation of their findings.

Therefore, option A is the statement that is not correct concerning qualitative and quantitative research.

Step-by-step explanation:

So every triangles angles will add up to 180 degrees no matter the triangle. Now a circle is 360 and a line is 180. Look at the line that A and C are on this line equals 180. So angle c and d added together make 180 and angles a b and c added together make 180. so if a+b+c = c+d then a+b=c. I hope thaqtmakes sense.

The correct answer is A) -12t.

To evaluate this expression, we need to use the order of operations. The order of operations is a set of rules that specifies the sequence in which operations should be performed in a math expression to get the correct result. The order of operations is typically abbreviated as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Following the order of operations, we first need to evaluate the expression inside the parentheses, which is 2+(-4t). This gives us 2-4t. Next, we need to perform the multiplication, which gives us 3(2-4t) = 6-12t. Finally, we need to perform the addition, which gives us -6+6-12t = -12t. Therefore, the expression -6+3(2+(-4t)) is equivalent to -12t.

Option B) 12t-12 is incorrect because the multiplication and addition operations are not performed in the correct order.

Option C) none of the above is incorrect because the correct answer is A) -12t.

Answer:

1 and -1

Step-by-step explanation:

The correct answer is 1. The square root of a (real) number is always taken to be the non-negative square root (this allows the square root operation to be a function).

However, if the question is saying it isn't 1, then it wants you to answer 1 and -1, because both square to 1. A better way to word the question would be "For which values of x is x^2 equal to 1?"

Actually, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y).

To see why, let's substitute y = 0 degrees into the expression:

sin(y)*tan(y) = cos(y)

sin(0)*tan(0) = cos(0)

0*tan(0) = 1

0 = 1

As we can see, the equation does not hold for y = 0 degrees. However, this does not make 0 degrees a counterexample, because 0 degrees is not in the domain of the tangent function.

The tangent function is undefined at odd multiples of 90 degrees (e.g. 90, 270, etc.), because at those angles the denominator of the tangent function becomes zero. Therefore, we cannot substitute y = 0 degrees into the expression sin(y)*tan(y) = cos(y), because it would result in division by zero.

In summary, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y), because it is not in the domain of the tangent function.

Answer:

y=3x+4

Step-by-step explanation:

Slope-intercept form is written as y=mx+b

m = the slope

slope is rise over run or (y2-y1)/(x2-x1). We need to choose which y value is y2 and the corresponding x value is the x2. If -2 is y2, then:

x2 = -2

y1 = 1

x1 = -1

then plug in the values.

(-2-1)/(-2-(-1))

-3/-1 = 3

m =3

then plug in values for the first equation. you can use any point on the line.

y = 3x+b

4 = 3*0 +b

4=0+b

b = 4

then write it with out x or y

y = 3x+4

The expected value is the long-term average outcome of a random variable. It is calculated by multiplying each possible outcome by its probability and summing them up. In simpler terms, it represents the average value we expect to get over many trials.

The expected value is a concept in probability and statistics that represents the long-term average outcome of a random variable. It is also known as the mean or average. To calculate the expected value, we multiply each possible outcome by its probability and sum them up.

For example, let's say we have a fair six-sided die. The possible outcomes are numbers 1 to 6, each with a probability of 1/6. To find the expected value, we multiply each outcome by its probability:

Summing up these values gives us:

1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6 = 21/6 = 3.5

Therefore, the expected value of rolling a fair six-sided die is 3.5. This means that if we roll the die many times, the average outcome will be close to 3.5.

The zeros of a function are the values of x when the function, f(x) is 0

The breaks in a function is a point where the function is discontinuous

The, domain, breaks and relationships of the functions f(x), g(x), and h(x) are as follows;

Part A:

The domain and range of the functions f(x) and g(x) are D(-∞, ∞), R(-∞, ∞) and D(-∞, -3] \(\bigcup\) [1, ∞), R[0, ∞) respectively

Part B:

The values of the breaks of the function h(x) and the zeros of the function f(x) are equal

The reason the above values are correct are as follows:

The given parameters are;

f(x) = x⁴ + 4·x³ - 2·x² - 12·x + 9

\(\mathbf{g(x)} = \sqrt{x^2 + 2\times x-3}\)

\(\mathbf{h(x)} = \dfrac{-x^2 + 1}{x^2+ 2 \times x- 3}\)

Part A: The function, f(x) = x⁴ + 4·x³ - 2·x² - 12·x + 9, has a value for all input, value, x, therefore, the domain of the function is D: -∞ < x < ∞

The range of the function f(x) is R: -∞ < y < ∞

The value of x² + 2·x -3 is less than 0 for -3 < x < 1

Therefore, the function, g(x) is not defined for -3 < x < 1, and the domain of the function is given as follows; -∞ < x ≤-3 \(\bigcup\) 1 ≤ x < ∞

The range of the function g(x) is R: 0 ≤ y < ∞

Therefore, the comparison is as follows;

The domain of the function f(x) is continuous and is D(-∞, ∞) . The domain of the function g(x) has a discontinuity from x = -3 to x = 1, and is therefore D(-∞, -3] \(\bigcup\) [1, ∞)

The range of the function is R(-∞, ∞), while the range of g(x) is R[0, ∞)

The functions intersect and have equal values at (-3, 0), and (1, 0)

Part B:

The breaks of the function h(x) is given by the zeros of the denominator, of h(x)

The zeros of the denominator of h(x), x² + 2·x - 3 are; x = -3, and x = 1

The zeros of f(x) = x4 + 4x3 – 2x2 – 12x + 9, are; x = -3, and x = 1

Therefore, the breaks of the function h(x) are at x = -3, and x = 1, which are the zeros of the function f(x)

The breaks of the function h(x) are at the same location and are equal to the zeros of the function f(x)

Based on the available evidence, there is insufficient support to suggest that the mean wind speed is higher than 261 mph. Consequently, we cannot conclude that wind speeds exceeding 261 mph were recorded.

Based on the given information, we can analyze the wind speed data using a hypothesis test. The criteria for a category five hurricane is a wind speed greater than 261 mph. The sample data provided has a mean of 265.1 mph, which exceeds the category five threshold.

The standard deviation of the sample is 41.09 mph, indicating a significant amount of variability within the data. The sample size is twenty, which is relatively small, making it challenging to draw general conclusions.

Since the sample size is less than 30 and the population standard deviation is unknown, we will employ a t-test to conduct the hypothesis test for the mean. The null hypothesis (H0) states that there is no evidence to suggest the wind speed is greater than 261 mph (μ = 261). The alternative hypothesis (Ha) proposes that there is enough evidence to indicate the wind speed is higher than 261 mph (μ > 261).

With a significance level of 0.05, we will use the t-test's critical value method to calculate the p-value and compare it to the significance level. This will help us determine if we should reject or fail to reject the null hypothesis.

Using the t-test formula, the test statistic is computed as follows:

t = (265.1 - 261) / (41.09 / √20) = 1.23

The resulting p-value for this test is 0.232. Since the p-value is greater than the significance level (0.05), we fail to reject the null hypothesis.

In a 7-stage pipeline without branch prediction, if the branch outcome is not known until the 6th stage, we can answer the following questions:

a) How many clock cycles will be wasted if a branch is taken?

b) How many clock cycles will be wasted if a branch is not taken?

Solution:

Part a)

If a branch is taken, then 2 instructions will be lost as it takes 6 cycles for an instruction to reach the end of the pipeline. Once the branch instruction reaches the 6th stage of the pipeline, it is realized that it needs to be taken, and so two instructions need to be flushed out of the pipeline.The next instruction that can be executed is in the 3rd stage of the pipeline, and this will take 5 cycles to complete. Therefore, the total number of clock cycles that will be wasted if a branch is taken = 2 + 5 = 7 cycles.

Part b)

If a branch is not taken, then one instruction will be lost as it takes 6 cycles for an instruction to reach the end of the pipeline. Once the branch instruction reaches the 6th stage of the pipeline, it is realized that it does not need to be taken, and so one instruction needs to be flushed out of the pipeline.The next instruction that can be executed is in the 4th stage of the pipeline, and this will take 4 cycles to complete. Therefore, the total number of clock cycles that will be wasted if a branch is not taken = 1 + 4 = 5 cycles.

Note:

In the case of branch prediction, the number of cycles wasted will be less.

This is because in the case of branch prediction, the branch outcome is predicted earlier (at the fetch stage itself) and so the pipeline can be flushed earlier (if the prediction is wrong). In this case, only a part of the pipeline is affected (up to the stage where the branch is predicted).
