The correct answer is n²+n+4. The quadratic expression in the multiplication table is of the form n² + an + b.

Quadratic is a type of equation involving one or more variables. It is an equation in the form of ax2 + bx + c = 0, where a, b, and c are constants and x is an unknown variable.

For the first quadratic equation x² + 5x + 6, we can see the coefficients of the n², n and constant terms are 1, 5 and 6 respectively. For the second quadratic equation x² + 4x + 3, the coefficients of the n², n and constant terms are 1, 4 and 3 respectively.

The third quadratic equation x² + 6x + 8 has the coefficients of the n², n and constant terms as 1, 6 and 8 respectively. The fourth quadratic equation x² + 5x + 4 has the coefficients of the n², n and constant terms as 1, 5 and 4 respectively.

Now, if we compare the coefficients of the n², n and constant terms with the last quadratic equation n² - 9n + 20, we can see that the coefficients of the n², n and constant terms are 1, -9 and 20 respectively.

Therefore, the correct answer is n²+n+4.

Step-by-step explanation:

To determine whether Alex is more likely to take a '3' card from Rex or from Nina, we need to compare the probabilities of drawing a '3' card from each of them.

Rex has four cards numbered 1 to 4, but we don't know the specific arrangement of the cards. Therefore, the probability of drawing a '3' card from Rex depends on how the cards are distributed. If Rex has a '3' card among his four cards, the probability of drawing it would be 1/4.

Nina, on the other hand, has five cards numbered 1 to 5. Since there is a '3' card among Nina's cards, the probability of drawing a '3' card from her is 1/5.

Comparing the probabilities, we can see that the probability of drawing a '3' card from Rex is higher (1/4) compared to drawing it from Nina (1/5). Therefore, Alex is more likely to take a '3' card from Rex

a. The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes.

b. The probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20

What is Probability?

Probability is a field of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of inaccuracy in study by using probability.

a. The mean of the sampling distribution of the difference in sample means, xF - xM, is equal to the difference of the population means, μF - μM = 8.8 - 7.3 = 1.5 minutes.

where σF and σM are the standard deviations of the populations of female and male students, respectively, and nF and nM are the sample sizes of female and male students, respectively.

\(Standard\ Deviation = \sqrt{3.3^2/8 + 2.9^2/8} \\\\Standard\ Deviation = \sqrt{{2.75} }\\\\Standard\ Deviation = 1.65\ minutes\)

So, the mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes, respectively.

b. The probability of getting a difference in sample means xF - xM that is less than 0 can be found using a standard normal distribution table. First, we need to standardize the difference in sample means xF - xM by subtracting the mean and dividing by the standard deviation:

z = (xF - xM - (μF - μM)) / standard deviation

z = (0 - 1.5) / 1.65 = -0.91

Looking up -0.91 in a standard normal distribution table, we find that the probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

So, there is a 20% probability of getting a difference in sample means xF - xM that is less than 0.

Hence, The mean and standard deviation of the sampling distribution of the difference in sample means xF - xM are 1.5 and 1.65 minutes and probability of getting a difference in sample means xF - xM that is less than 0 is approximately 0.20.

Using the properties of multiplication to compare the expressions 3 to the eighth power and 3 to the fifth power x 3 to the third power, it can be seens that that the two expressions are equal to each other.

The properties of multiplication state that when multiplying two expressions with the same base, we can add their exponents together. This means that 3 to the fifth power x 3 to the third power is equal to 3 to the eighth power.

In mathematical notation, this looks like:

3^8 = 3^5 x 3^3

Using the properties of multiplication, we can add the exponents together:

3^8 = 3^(5+3)

Simplifying the exponent:

3^8 = 3^8

This shows that the two expressions are equal to each other. Therefore, we can conclude that 3 to the eighth power and 3 to the fifth power x 3 to the third power are the same value.

To find the value of cot 8, we can use the fundamental trigonometric identity: cot(theta) = 1 / tan(theta).

Since we know that csc(0) = -sqrt(33) and it is in quadrant III, we can determine the value of sin(0) and cos(0) using the Pythagorean identity: sin^2(theta) + cos^2(theta) = 1.

In quadrant III, sine is negative, so sin(0) = -sqrt(33).

Using the Pythagorean identity, we can calculate cos(0):

sin^2(0) + cos^2(0) = 1

(-sqrt(33))^2 + cos^2(0) = 1

33 + cos^2(0) = 1

cos^2(0) = 1 - 33

cos^2(0) = -32

Since cosine is positive in quadrant III, we take the positive square root:

cos(0) = sqrt(-32) = sqrt(32)i = 4sqrt(2)i

Now, we can find the value of tan(0) using the definition: tan(theta) = sin(theta) / cos(theta):

tan(0) = sin(0) / cos(0)

tan(0) = (-sqrt(33)) / (4sqrt(2)i)

tan(0) = -sqrt(33) / (4sqrt(2)i) * (sqrt(2)/sqrt(2))

tan(0) = -sqrt(33) * sqrt(2) / (4sqrt(2)i * sqrt(2))

tan(0) = -sqrt(66) / (4i)

tan(0) = -sqrt(66) / 4i

Finally, we can find cot(8) using the reciprocal property:

cot(8) = 1 / tan(8)

cot(8) = 1 / (-sqrt(66) / 4i)

cot(8) = 1 * (-4i) / (-sqrt(66))

cot(8) = 4i / sqrt(66)

Therefore, the value of cot 8 is 4i / sqrt(66).

Answer:

angle BAC = 50.5°

Step-by-step explanation:

To find the size of angle BAC, we will follow the steps below;

First, we will use Pythagoras theorem to find side AC

from the diagram, AB = 14 cm       BC = 17 cm

Using Pythagoras theorem,

AC² = AB² + BC²

        = 14² + 17²

         =196 +289

           =485

AC² = 485

Take the square root of both-side

AC = √485

AC = 22 .023

AC = 22.023 cm

angle <B = 90°

Using the sine rule,

\(\frac{sin A}{a}\)   =  \(\frac{sin B}{b}\)

A = ?

a=BC = 17 cm

B = 90°

b = AC = 22.023 cm

we can now [proceed to insert the values into the formula and then solve for A

\(\frac{sin A}{a}\)   =  \(\frac{sin B}{b}\)

\(\frac{sin A}{17}\)  = \(\frac{sin 90}{22.023}\)

cross - multiply

22.023× sinA = 17× sin90

Divide both-side of the equation by 22.023

sin A = 17 sin90 / 22.023

sin A = 0.771920

Take the sin⁻¹ of both-side of the equation

sin⁻¹sin A = sin⁻¹0.771920

A = sin⁻¹0.771920

A≈ 50.5°

Therefore, angle BAC = 50.5°
