La altura del triangulo está dada por el polinomio:

p(x) = a + 4

Recordar que para un triangulo de base B y altura H, el area es

A = B*H/2

En este caso, sabemos que la base es B = (4*a^2 + 6)

Y el area es A = 2a^3 + 8a^2 +3a +12

Entoces la altura será un polinomio tal que:

P(a)*(4*a^2 + 6)/2 = 2a^3 + 8a^2 +3a +12

P(a)*(4*a^2 + 6) = 2*(2a^3 + 8a^2 +3a +12) = 4a^3 + 16a^2 + 6a + 24

Podemos ver que p(a) va a ser un polinomio de grado 1, entonces:

p(a) = (c*a + b)

Reemplazando eso:

(c*a + b)*(4*a^2 + 6) = 4a^3 + 16a^2 + 6a + 24

Expandiendo:

(4c)*a^3 + (6c)*a + (4b)*a^2 + 6*b = 4a^3 + 16a^2 + 6a + 24

Comparando terminos del mismo exponente, podemos ver que:

(4c) = 4

6c = 6

4b = 16

6b = 24

Resolviendo esas ecuaciones para c y b, podemos ver que:

b = 16/4 = 4

c = 4/4 = 1

Entonces la altura del triangulo está dada por el polinomio:

p(x) = a + 4

It is not possible to get a very strong correlation just by chance when there is no relationship between the two variables. False

Correlation measures the strength and direction of the linear relationship between two variables. A high correlation coefficient indicates a strong relationship between the variables, while a low or near-zero correlation suggests a weak or no relationship.

A strong correlation implies that changes in one variable are associated with predictable changes in the other variable. Therefore, a high correlation cannot occur by chance alone without an underlying relationship between the variables.

a) The intersection of sets b and c, denoted as b ∩ c, is {d}. This is because the elements common to both sets b and c are {d}.

b) The set ac u b c is {a, b, c, d, e, h}. This is the union of the sets ac, b, and c, which means it includes all the elements that are present in any of the three sets. Combining sets ac (which is equal to a) with b and c gives us {a, b, c, d, e, h}.

c) To find the set (a ∩ cc) c, we need to evaluate the complement of the intersection of a and the complement of c. First, the complement of c is {a, b, d, f, g, h}. The complement of c is found by considering all the elements that are not present in c but are present in the universal set u. Then, we find the intersection of a and cc (complement of c), which is {a, b, d}.

Finally, taking the complement of this set gives us {c, e, f, g, h} as the answer. This set includes all the elements that are not present in the intersection of a and cc.

The solution of the inequality is x ≥ 3.

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Let's find the solution of the inequality as follows;

5x - 10 ≥ - 3x + 14

5x - 10 ≥ -3x + 14

add 10 to both sides of the inequality

5x - 10 + 10 ≥ -3x + 14 + 10

5x ≥ -3x + 24

add 3x to both sides of the inequality

5x ≥ -3x + 24

5x + 3x ≥ -3x + 3x + 24

8x ≥ 24

divide both sides by 8

The original price of the tire will be equal to $160.4.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Gary had a 40% discount for new tires. The sale price of a tire was $96.25.

Let the original price of the tire be x. Now form the equation to have the price of the tire,

x ( 0.60 ) = $96.25

x = $96.25 / 0.60

x = $160.4

Therefore, the original price of the tire will be equal to $160.4.

6^1/3 is equivalent to 3√6

Let

k = 1/3

6^k = 3√6

Cube both sides of the equation

(6^k)^3 = (3√6)^3

(3√6)^3 ( cube root cancel power cube (

6^3k = 6^1

They both have the same base, so it cancels out

3k = 1

Here it's sayin that Q is a point in between the end-points P & R. If we join P & R , it forms a line segment & Q is in the line segment PR. Hence PQ & QR are also line segments which combine to form line segment PR. So ,

PR = PQ + QR

Putting the given values of PQ ,QR & PR

True. Exception reports show a greater level of detail than is included in routine reports.

Exception reports are reports that help in identifying data that does not conform to expected patterns. Exception reports show information about an exception in the data set.

This helps to identify irregularities or anomalies in data or system operations.Exception reports are used to analyze system performance, monitor resource consumption, and to detect unusual activity.

This type of report is important to identify issues or errors, where the routine reports or standard reports would not provide enough detail or insight to do so.

It provides detailed information on any unusual event or anomaly that occurred beyond the usual course of events or processes.Exception reports are generated and distributed when the data is not expected or when an event occurs that is outside of what is considered typical.

For example, a financial system might generate an exception report if a transaction is entered that exceeds the maximum allowed amount. This report would show the details of the transaction and highlight the exception.

The purpose of exception reports is to provide users with a higher level of detail than they would find in routine reports. Exception reports are used to highlight significant data, which will be used for further analysis or action.

The probability of a Type II error is represented by beta. Thus, the correct answer is option B.

Beta represents the probability of failing to reject the null hypothesis when it is false.

On the other hand, Type I error (alpha) represents the probability of rejecting the null hypothesis when it is true. A Type II error occurs when a false null hypothesis is not rejected. Hence, beta is the probability of making a Type II error.

The null hypothesis is rejected when the p-value is less than or equal to the level of significance, not exceeds it.

The p-value is the probability of obtaining a result as extreme as or more extreme than the observed result when the null hypothesis is true. If the p-value is less than the level of significance, the null hypothesis is rejected, and vice versa.

Hence, the statement "The null hypothesis is rejected when the p-value exceeds the level of significance" is false.

We accert H1 alternative that is result is population mean greater than 400.

There is a 2.1% chance than mean second Trimester weight gain for all expectant mothers is 14 pounds in 2015.

What is standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

We have given: μ = 14, x bar = 16, n = 40, s = 6,  α = 5%, = 0.05

To test μ0 : μ = 14   Vs  H1: μ > 14

Test statistics = (X bar - μx)√n / sx = (2 x 6.3245) / 6 = 2.1081

So, P value = 0.021

Conclusion: There is a 2.1% chance than mean second Trimester weight gain for all expectant mothers is 14 pounds in 2015.

P value for the hypothesis test

n = 50, x bar = 420, sx = 81, μ = 400,

To test:  H0: μ 400    Vs   H1:  μ > 400

It is right tail test

Test statistics =  (X bar - μx)√n / sx = (420 - 400) √50 / 81 =

z = 1.7459

P value = 0.04093

Declsion: We reject H0 is p value < α

Here α = 0.05

Hence P value < α

Conclusion: We accert H1 alternative that is result is population mean greater than 400.

Hence, we accert H1 alternative that is result is population mean greater than 400.

There is a 2.1% chance than mean second Trimester weight gain for all expectant mothers is 14 pounds in 2015.
