Answer:

La ecuación de la recta es \(y = -6\cdot x +23\).

Step-by-step explanation:

Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:

\(x+4\cdot y = 0\) (1)

\(x-3\cdot y = 7\) (2)

La solución del sistema de ecuaciones es \((x,y) = (4,-1)\).

Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:

\(y = m\cdot x + b\) (3)

Donde:

\(x\) - Variable independiente.

\(y\) - Variable dependiente.

\(m\) - Pendiente.

\(b\) - Intercepto.

Si sabemos que \((x,y) = (4,-1)\) y \(m = -6\), entonces el intercepto de la recta es:

\(b = y-m\cdot x\)

\(b = 23\)

Ahora, la ecuación de la recta es \(y = -6\cdot x +23\).

The chances of conducting a hypothesis are positive, under the condition that the proportion of students who attend school is lower than 0.95.

the null hypothesis of the portion of students who attend school is lower than 0.95.

therefore, the test statistics for a population portion are calculated using the formula

\(TS =(P' - P)\sqrt{(P(1-P)/n)}\)

here,

P' = sample population

P = hypothesized population

n = sample size

staging the values according to the given question,

P' = 0.875

P = 0.95

n = 120

then,

\(TS = (0.875 - 0.95) \sqrt{(0.95 * (1 - 0.95) / 120)} = -2.53\)

using the principles of the standard normal distribution table we conclude that there is a 0.56% chance of observing a sample portion as an extreme 0.875 or less. So the population of students who attend the school is less than 0.95.

We can say that after answering the offered question Hence, p > 8 is the equation inequality expressing the range of feasible values for p.

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Let's use the letter "p" to indicate how many pounds Carmen will spend.

Candy is $7 for every pound.

Carmen's sweets expenditure is expressed as follows:

Cost per pound times the weight of the candy purchased is 7p.

Carmen will undoubtedly spend more than $56 on sweets, therefore we may say:

More than $56 was spent on candy

Using the following equation in place of the amount spent on candy:

7p > $56

When we multiply both sides by 7, we get:

p > 8

So, any figure more than 8 is a possibility for the amount of pounds Carmen will purchase. We can express this as follows:

p > 8

Hence, p > 8 is the inequality expressing the range of feasible values for p.

If the calculated value of correlation coefficient is greater than 0.532, then the correlation is significant at the 0.05 level.

In order to calculate the critical value for the testing of correlation, significance level needs to be considered. If the correlation is significant at 0.05 level, then the critical value for the testing is 0.05. This implies that the calculated value of correlation coefficient is significant as compared to the value of critical correlation at the 0.05 level.

The correlation coefficient value can range from -1 to +1. The correlation coefficient can be used to determine the degree of relationship between the two variables.

A correlation coefficient of 0 indicates no correlation between two variables, while a correlation coefficient of -1 or 1 indicates a perfect negative or positive correlation, respectively.

In this case, the correlation coefficient between score and first year GPA is 0.529. This indicates a moderate positive correlation between the two variables.

Now, to determine the critical value for the testing, we need to use the significance level which is 0.05 in this case. The critical value for this significance level is 0.532.

Therefore, if the calculated value of correlation coefficient is greater than 0.532, then the correlation is significant at the 0.05 level.

The correlation between the score and first-year GPA is 0.529. To find the critical value for the testing if the correlation is significant at =.05, we can use the formula:r= (t√n-2)/√1-r²

Where r = 0.529, n = sample size, and t = critical value

Let's assume the sample size is 30. Then the degrees of freedom will be 28 (n-2).

The critical value of t for a two-tailed test at the .05 level with 28 degrees of freedom is 2.048.

Using the formula:r= (t√n-2)/√1-r²0.529 = (2.048√30-2)/√1-0.529²

Solving for √1-0.529² = 0.846.0.529 = (2.048√28)/0.8462.048*0.846 = 1.732t = 0.529 * 1.732 = 0.915

So, the critical value for the testing if the correlation is significant at =.05 is 0.915.

In the short-run model for a typical monopolistically competitive firm at profit maximization, the total revenue is $X, total costs are $Y, and the total economic profit is $Z.

In the short-run model for a typical monopolistically competitive firm, profit maximization occurs when marginal revenue (MR) equals marginal cost (MC). The total revenue of the firm, denoted as TR, is the product of the price per unit (P) and the quantity sold (Q). Therefore, TR = P × Q.

To determine the total costs (TC) of the firm, we need to consider both explicit costs (such as wages, rent, and raw material expenses) and implicit costs (such as the opportunity cost of the owner's time and capital invested). TC includes both the variable costs (VC), which change with the level of production, and the fixed costs (FC), which remain constant regardless of the production level. Thus, TC = VC + FC.

Finally, to calculate the total economic profit, we subtract the total costs (TC) from the total revenue (TR). Economic profit (π) is given by the equation π = TR - TC. If the economic profit is positive, the firm is making profits. If it is negative, the firm is incurring losses. If it is zero, the firm is just breaking even.

Overall, in the short-run model for a monopolistically competitive firm at profit maximization, the total revenue (TR) is $X, the total costs (TC) are $Y, and the total economic profit (π) is $Z. These figures are crucial for understanding the financial performance of the firm and its position in the market.

To find the total surface area of a cone, we need to add the area of the base to the lateral surface area. The lateral surface area of a cone is the curved surface area that makes up the slanted sides of the cone.

The formula for the lateral surface area of a cone is given by:

Lateral surface area of cone = πrℓ

where r is the radius of the base of the cone and ℓ is the slant height.

Here, the radius of the base is 5 cm and the slant height is 9 cm.

So, the lateral surface area of the cone is:

Lateral surface area = πrℓ

= π × 5 × 9

= 45π cm²

The formula for the area of the base of a cone is:

Area of base of cone = πr²

where r is the radius of the base.

Here, the radius of the base is 5 cm.

So, the area of the base of the cone is:

Area of base = πr²

= π × 5²

= 25π cm²

Therefore, the total surface area of the cone is:

Total surface area = Lateral surface area + Area of base

= 45π + 25π

= 70π cm²

So, the total surface area of the cone is 70π cm².

A major branch of algebra called pre-algebra is used to get pupils ready for a typical high school algebra course. Students learn about integers, fraction, square roots, step equations, linear equations, and decimals, as well as how to use variables to solve simple equations.

The stock price on Monday morning

= $43.66

Amount of stock price on Tuesday

= 3/4 of $43.66

= 32.745

The change to a someone bank account if they bought 9 shares of stock on Monday

= single day share value x 9

Single day share value

= Monday's amount - Tuesday's amount

= 43.66 - 32.745

= 10.915 dollars

So the value will be

p < 0.05, there is sufficient evidence to conclude that the machines' maker should perform a recalibration.

Given,

The test statistics formula for finding the z-score is,

z = (X - μ)/(σ/√n)

Where,

X = sample mean

μ = population mean

σ = population standard deviation

n = sample size

This z-score is used to determine the p-value. The null hypothesis is not rejected if p > α, and it is rejected if p < α.

Here,

The population mean μ = 4.00

The sample size n = 196

The sample mean X = 4.14

The standard deviation σ = 0.83

The significance level α = 0.05

So, the hypothesis is:

The null hypothesis: H0: μ = 4

The alternative hypothesis: Ha: μ ≠ 4

Thus, the test statistic value is,

z = (X - μ)/(σ/√n)

= (4.14 - 4)/(0.83/√196)

= 2.36

So, for z = 2.36, the p-value is 0.009137

Therefore,

The provided significance level of 0.05 is not met by the p-value of (0.009137). Therefore, there is enough evidence to support the claim that the machines' manufacturer needs to recalibrate them.
