find the value of b if a+b+c/4=2 where a = 1 and c=2​

Answer:

\(x=0, \\x=\pi\)

Step-by-step explanation:

Recall the trigonometric identity \(\sin 2x=2\sin x\cos x\).

Therefore, given \(\sin 2x=2\sin x\), rewrite the left side of the equation:

\(2\sin x\cos x=2\sin x\)

Subtract \(\sin x\) from both sides:

\(2\sin x\cos x-2\sin x=0\)

Factor out \(2\sin x\) from both terms on the left:

\(2\sin x(\cos x-1)=0\)

We now have two cases:

\(\begin{cases}2\sin x=0, x=k\pi\text{ for }k\in \mathbb{Z}\\\cos x-1=0,x=k2\pi\text{ for }k\in \mathbb{Z}\end{cases}\)

Since the problem stipulates that \(x\) is in the interval \([0, 2\pi)\), we have:

\(\text{For }x\in [0, 2\pi):\\\sin x=0\rightarrow \boxed{x=0, x=\pi}\\\cos x-1=0\rightarrow \boxed{x=0}\)

Recall that square brackets mean inclusive and parentheses mean exclusive. Therefore, \(2\pi \notin [0, 2\pi)\).

C) g(x) = f(x) + 4

Step-by-step explanation:

A vertical shift is where you shift, slide or translate the whole graph up or down (on a graph) The way this shows up in the equation is just a number tacked on to the end of the equation. A +anumber (like the +4 in the answer) slides the function UP four units. A

-anumber would slide the function DOWN instead.

The underlying function f(x - i) that generates the observed points f'(x - i) in the plot can be determined by integrating the observed points. By integrating f'(x - i), we can obtain f(x - i) up to a constant of integration.

The constant of integration can be determined by incorporating additional information or constraints related to the problem or by considering the behavior of the function at a specific point.

To find the underlying function f(x - i) that generates the observed points f'(x - i), we need to integrate the observed points.

Integration is the reverse process of differentiation, so by integrating f'(x - i), we can recover f(x - i) up to a constant of integration.

The constant of integration arises because integration does not provide a unique solution.

The constant represents an arbitrary additive term that can vary depending on the specific problem or additional constraints.

To determine the constant of integration, we may need additional information or consider specific conditions related to the problem.

It is also important to note that the accuracy of estimating the underlying function f(x - i) depends on the quality and quantity of the observed data points f'(x - i). More data points and precise measurements can lead to a better estimation of the underlying function.

Additionally, the behavior of the function at a specific point can provide valuable insights for determining the constant of integration and refining the estimation of the underlying function.

Option 2 is correct that is 1.79

When presented in ascending order, the value that 75% of data points fall within is known as the higher quartile, or third quartile (Q3).

The quartiles formula is as follows:

Upper Quartile (Q3) = 3/4(N+1)

Lower Quartile (Q1) = (N+1) * 1/3

Middle Quartile (Q2) = (N+1) * 2/3

Interquartile Range = Q3 -Q1,

1.74, 0.24, 1.56, 2.79, 0.89, 1.16, 0.20, and 1.84 are available.

Sort the data as follows: 0.20, 0.24, 0.89, 1.16, 1.56, 1.74, 1.84, 2.79 in ascending order of magnitude.

The data set has 8 values.

hence, n = 8; third quartile: 3/4 (n+1)th term

Q3 =3/4 of a term (9) term

Q3 =27/4 th term

Q3 = 1.74 + 1.84 / 2 (average of the sixth and seventh terms)

equals 1.76

Thus Q3 is 1.76 that is option 2

Answer:

I think the answer is B

Step-by-step explanation:

Okay, let's visualize this.

Step 1:

The question says that you have three times a number. Since we don't know the number, we could x. Three times that would be 3n.

Step 2:

Now that number is increased by 4. In math, when a number is increased, it means adding because you are growing something when you add. Similar to raising your TV's volume, you add decibels. Okay, so the equation would come out to \(3n+4\).

Step 3:

The next part of the question says it is "less than 62". So if x is less than y, it would be represented   \(x < y\) because the less than symbol points away from the smaller number. Therefore the answer is \(3n+4 < 62\).

I hope this helped, and feel free to ask any other questions. The wide brainly community and I will do our best to answer them. :)

Answer:

A: (-2, 0.5)

B: (0,0.5)

C: (0.5,-0.5)

D: (-1.5, -0.5)

Step-by-step explanation:

When dilating about the origin, the distance of each point from the origin changes by the scale factor. For example, if you had a point that was 4 units above the center of dilation, and a scale factor of 1/2, the point would change to be 2 units above the center of dilation, because 1/2 x 2.

To find the image of parallelogram ABCD after a dilation with center (0,0) and a scale factor of 1/2, we need to apply the following transformation to each of the vertices of the parallelogram:\((x, y) to (\frac{1}{2} x, \frac{1}{2}y)\) So, for vertex A (a, b), the image will be (1/2a, 1/2b). Similarly, for vertex B (c, d), the image will be (1/2c, 1/2d), and so on.Therefore, the coordinates of the image of parallelogram ABCD will be:

A' (1/2a, 1/2b)

B' (1/2c, 1/2d)

C' (1/2e, 1/2f)

D' (1/2g, 1/2h)

where A (a, b), B (c, d), C (e, f), and D (g, h) are the coordinates of the vertices of parallelogram ABCD.

Now, to solve this, we input the coordinates.

A has coordinates of (-4,1). 1/2(-4) = -2 and 1/2(1) = 0.5, so A is (-2, 0.5)

B has coordinates of (0,1). 1/2(0) = 0 and 1/2(1)= 0.5. B is  (0, 0.5)

C has coordinates of (1,-1). 1/2(1) = 0.5 and 1/2(-1) = -0.5. C is (0.5, - 0.5)

D has coordinates of (-3,-1). 1/2(-3) = -1.5 and 1/2(-1) = -0.5. D is (-1.5, -0.5)

Let me know if this helped by hitting thanks or brainliest! If you have any questions, comment below and I'll get back to you ASAP.

The coordinates of the image of parallelogram ABCD after a dilation with center (0, 0) and a scale factor of 1/2 are A'(-2, 0.5), B'(0, 0.5),   C'(0.5, -0.5) and D'(-1.5, -0.5).

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.

Given that, the scale factor is 1/2.

Here, vertices of parallelogram ABCD is A(-4, 1), B(0, 1), C(1, -1) and D(-3, -1).

After dilation we get,

A(-4, 1) → 1/2(-4, 1) → A'(-2, 0.5)

B(0, 1) → 1/2(0, 1) → B'(0, 0.5)

C(1, -1) → 1/2(1, -1) → C'(0.5, -0.5)

D(-3, -1) → 1/2(-3, -1) → D'(-1.5, -0.5)

Therefore, the coordinates of the image of parallelogram ABCD after a dilation with center (0, 0) and a scale factor of 1/2 are A'(-2, 0.5), B'(0, 0.5),   C'(0.5, -0.5) and D'(-1.5, -0.5).

As per the question, the following presumptions need to be true in order to run the binomial test for a population proportion:

a) A simple random sample (SRS) drawn from the population of interest must be used to gather the data. The sample's observations must be unrelated to one another. A binary answer variable is required (i.e., it can only take on two possible values, such as "success" and "failure").

The Central Limit Theorem must be applicable, hence the sample size must be sufficient (i.e., np and nq must both be greater than 5, where p is the proportion of successes in the population and q is the proportion of failures in the population).

From the facts given, it is unclear whether these presumptions are true. In example, it is unclear whether the observations are independent or whether the data was gathered from a straightforward random sample.

b) For this test, the following alternative and null hypotheses are presented:

The actual percentage of female students at ACME University is 0.64, which is null. Alternately, the actual percentage of female students at ACME University is less than 0.64.

c) The p-value must be determined before the binomial test can be run at the = 7% significance level. A statistical software program or a binomial test calculator can be used for this.

The p-value for this test is 0.05309 assuming the binomial test assumptions are met. This suggests that there is a 5.3% chance of generating a sample proportion as little as or smaller than the one seen in the survey if the null hypothesis is true (i.e., the true proportion of women among ACME University students is 0.64).

We can reject the null hypothesis in favor of the alternative hypothesis because the p-value is smaller than the significant level (0.05309 0.07). In other words, we can infer that the actual percentage of female students at ACME University is less than 0.64.

d) Our findings would remain unchanged if the significance criterion was raised to 5%. Because the p-value is still below the significance level (0.05309 0.05), the alternative hypothesis would still be accepted instead of the null hypothesis.

Answer:

k = 9.34

Step-by-step explanation:

The number of Miles a car can be driven is proportional to the number of gallons of gasoline it uses.

x ∝ g

x = kg ....(1)

k is constant of proportionality, x is no of miles and g is no of gallons

The car can be driven 14 miles per one and a half gallon of gasoline used.

Here x = 14 and g = \(1\dfrac{1}{2}=\dfrac{3}{2}\)

Put values in equation (1) to find k.

\(k=\dfrac{14}{\dfrac{3}{2}}\\\\x=9.34\)

Hence, the value of constant of proportionality is 9.34.

x = -1/2                    Division

Answer: x=-1/2 in decimal form -0.500

Step-by-step explanation:  Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*(2*x-7)+5-(-19)=0

3 • (2x - 7) +  5) -  -19  = 0

Pull out like factors :

  6x + 3  =   3 • (2x + 1)

Solve  :    2x+1 = 0  

Subtract  1  from both sides of the equation :  

                     2x = -1

Divide both sides of the equation by 2:

                    x = -1/2 = -0.500
