Answer:

34.50

Step-by-step explanation:

46.00×0.25=11.50. 46.00-11.50=34.50

The solution of the quadratic equation is x=5±√35 .

A quadratic equation is given by the equation which can be written in the form ax²+bx +c.

the given quadratic equation is :

x²-10x+25=35

Simplifying the equation we get:

or, x²-10x+25-35=0

or, x²-10x-10=0

Now we will solve the equation by completion squares method:

x²-10x-10=0

or, x²-2×x×5+5²-5²-10=0

or, (x-5)²=35

or, x-5=±√35

or, x= 5±√35

Therefore the solution of the quadratic equation is 5+√35 and 5-√35 .

The equation of the line y = 3x + 10 in standard form is 3x - y = -10.

Given the equation of line in the question:

y = 3x + 10

To write the equation of the line in standard form, we need to rearrange the equation so that the x and y terms are on the left side and the constant term is on the right side of the equation.

It is expressed as;

Ax + Bx = C

y = 3x + 10

Subtracting 3x from both sides, we get:

y - 3x = 3x - 3x + 10

y - 3x = 10

Reorder

-3x + y = 10

Multiply each term by -1

-3x(-1) + y(-1) = 10(-1)

3x - y = -10

Therefore, the equation in standard form is 3x - y = -10.

The values of a1 = [ 3], a2 = [ 9 ], and b = [ 48] and b is not a linear combination of a1 and a2. The correct answer is (a).

To check if b is a linear combination of a1 and a2, we need to see if there exist scalars x and y such that:

x * a1 + y * a2 = b

Substituting the given values, we get:

x * [3] + y * [9] = [48]

[-3] [-9] [-48]

This system of linear equations can be solved using standard methods, such as Gaussian elimination. However, we can quickly see that there are no values of x and y that satisfy the equation.

First, note that the first two rows of the equation system are linearly dependent, since the second row is a multiple of the first row. Therefore, we only have two independent equations to solve for three unknowns (x, y, and z).

If we subtract the first equation from the second equation, we get:

6y = 0

This implies that y = 0. Substituting y = 0 in the first equation, we get:

3x = 48

This implies that x = 16. Substituting these values in the third equation, we get:

0 ≠ -48

Since there are no values of x and y that satisfy the equation system, we can conclude that b is not a linear combination of a1 and a2. Therefore, the answer is (a) b is not a linear combination.

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Part A: The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: The point (8, 2) is not included in the solution area.

Part C: The point (3, 1) represents one feasible solution that meets the constraints of the problem.

Part A: The graph of the system of inequalities consists of two lines and a shaded region. The line x + 3y = 8 is a solid line because it includes the equality symbol, indicating that points on the line are included in the solution set. The line x + y = 2 is also a solid line. The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: To determine if the point (8, 2) is included in the solution area, we substitute the x and y values into the inequalities:

8 + 3(2) ≤ 8

8 + 6 ≤ 8

14 ≤ 8 (False)

Since the inequality is not satisfied, the point (8, 2) is not included in the solution area.

Part C: Let's choose a point in the solution set, such as (3, 1). This point satisfies both inequalities: x + 3y ≤ 8 and x + y ≥ 2. In the context of the real-world scenario, this means that Michelle can buy 3 servings of dry food (x = 3) and 1 serving of wet food (y = 1) with her $8 budget.

The value of \(\lim _{x \rightarrow 2}\) f(x) by Sandwich theorem is 2.

As per the given data the function limits are:

2x − 2 ≤ f(x) ≤ x2 − 2x + 2 for x ≥ 0

Here we have to determine the value of \(\lim _{x \rightarrow 2}\) f(x)

Hence by Sandwich theorem:

The sandwich theorem, also known as the squeeze theorem, asserts that if two functions, g (x) and h (x), are squeezed between one another and their respective limits at a given position are both equal to L, then the limit of f (x) at that point is also equal to L.

We can use the theorem to find tricky limits like sin(x)/x at x=0, by "squeezing" \(\frac{sin(x)}{x}\) between two nicer functions and ​using them to find the limit at x = 0.

\(& \lim_{x \rightarrow 2}(2 x-2) \leq\lim_{x \rightarrow 2} f(x) \leq \lim_{x \rightarrow 2}\left(x^2-2 x+2\right) \\\)

\(& \Rightarrow 2 \leq \lim _{x \rightarrow 2} f(x) \leq 2 \\\)

Hence \(\lim _{x \rightarrow 2}\) f(x) = 2

The confidence interval for the proportion of registered voters who believe illegal immigrants who have lived in the United States since they were children should be eligible for legal citizenship is 0.5998 to 0.6602.

To analyze the results of the poll, we can use the given information to calculate the confidence interval.

Given:

- Sample size (n): 904 registered voters

- Proportion who answered "should be" eligible for legal citizenship (p): 63%

- Margin of error (E): 3%

- Confidence level: 95%

To calculate the confidence interval, we can use the formula:

Confidence Interval = p ± (Z * √((p * (1 - p)) / n))

First, let's find the critical value (Z) corresponding to a 95% confidence level. Since the confidence level is 95%, the alpha level (α) is 1 - 0.95 = 0.05. Dividing this by 2 (for a two-tailed test), we have α/2 = 0.025. Looking up this value in the Z-table, we find that the critical value Z is approximately 1.96.

Next, we can substitute the values into the formula and calculate the confidence interval:

Confidence Interval = 0.63 ± (1.96 * √((0.63 * (1 - 0.63)) / 904))

Confidence Interval = 0.63 ± (1.96 * √((0.63 * 0.37) / 904))

Confidence Interval = 0.63 ± (1.96 * √(0.23211 / 904))

Confidence Interval = 0.63 ± (1.96 * 0.0154)

Confidence Interval = 0.63 ± 0.0302

Therefore, the confidence interval for the proportion of registered voters who believe illegal immigrants who have lived in the United States since they were children should be eligible for legal citizenship is approximately 0.5998 to 0.6602.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Two right triangles are supposed to be consistent on the off chance that they are of a similar shape and size. All in all, two right triangles are supposed to be consistent in the event that the proportion of the length of their comparing sides and their relating points is equivalent.

Answer:

Step-by-step explanation:

i think the answer is 380 but i am not sure  

Given:

S.P. = 315

Loss percent = 10%

To find:

The C.P.

Solution:

Let x be the C.P.

We have,

S.P. = 315

Loss percent = 10%

\(S.P.=C.P.-10\%\text{ of }C.P\)

\(315=x-\dfrac{10}{100}x\)

\(315=x-0.1x\)

\(315=0.9x\)

Divide both sides by 0.9.

\(\dfrac{315}{0.9}=x\)

\(350=x\)

Therefore, the cost price (C.P.) is 350.
