  A = \(\left[\begin{array}{cc}4&-4\\3&-2\end{array}\right]\)

3B = \(\left[\begin{array}{cc}12&12\\0&3\end{array}\right]\)

4 + 12 = 16 ; 12 + ( - 4) = 8

In order to calculate the t statistic, you first need to calculate the pooled variance under the assumption that the null hypothesis is true.

In order to calculate the t statistic, you first need to calculate the pooled variance under the assumption that the null hypothesis is true. The standard error is a measure of the variability of the sample means around the true population mean. It takes into account the sample size and the variability of the data. Once you have calculated the standard error, you can then use it to calculate the t statistic, which is a measure of how far the sample mean deviates from the null hypothesis mean, relative to the standard error. The pooled variance is used when you are comparing two independent samples, but it is not necessary for calculating the t statistic in a single sample scenario where the null hypothesis is true.

The equivalent expression for 1.5 cubed over 1.3 raised to the fourth power all raised to the power of negative six is 1.5 to the eighteenth power over 1.3 to the twenty-fourth power.

Here are the steps to simplify the expression:

Apply the negative power rule: (1.5 cubed over 1.3 raised to the fourth power) raised to the power of negative six is equal to (1.3 raised to the fourth power over 1.5 cubed) raised to the power of six.

Apply the power of a quotient rule: (1.3 raised to the fourth power over 1.5 cubed) raised to the power of six is equal to (1.3 raised to the fourth power)⁶ / (1.5 cubed)⁶.

Apply the power of a power rule: (1.3 raised to the fourth power)⁶ is equal to 1.3(⁴*⁶) = 1.3²⁴.

Apply the power of a power rule: (1.5 cubed)⁶ is equal to 1.5(³*⁶) = 1.5¹⁸.

The answer of the given question based on the word problem of multiplication is , option (c) Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.

Total cost refers to the complete amount of money required to purchase or produce a given quantity of goods or services. It includes all the expenses involved in the production or purchase of the product or service, like materials, labor, and overhead costs, as well as any other additional expenses like  taxes or shipping fees. Total cost is an important concept in economics and accounting as it helps businesses and individuals to determine the profitability of a product or service and make informed decisions about pricing and production.

The answer is: "Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00."

Rounding can be used to estimate the total cost of the stamps by approximating the cost of each stamp to the nearest 50 cents, which is $0.50. Therefore, the cost of four stamps can be estimated as 4 multiplied by 0.50, which is $2.00.

there are 91 2-digit numbers : 10 ..99

and there are 9 2-digit numbers with identical first and second digit : 11, 22, 33, 44, 55, 66, 77, 88, 99

99 has to be excluded, because there are no 2 2- digit numbers that I can subtract from each other and get 99.

The probability of rolling a 6 with the red die, a 5 with the green die, and a 4 with the blue die at the same time is 1/216, or approximately 0.46%.

Assuming that each die is fair and that the outcome of rolling one die does not affect the outcome of rolling the others, the probability of rolling a 6 with the red die is 1/6, the probability of rolling a 5 with the green die is also 1/6, and the probability of rolling a 4 with the blue die is 1/6.

Since the three events of rolling each die are independent of each other, we can multiply their probabilities to get the probability of all three events happening at the same time, i.e., rolling a 6 with the red die, a 5 with the green die, and a 4 with the blue die:

Probability of rolling 6 with the red die = 1/6

Probability of rolling 5 with the green die = 1/6

Probability of rolling 4 with the blue die = 1/6

Probability of rolling 6 (R), 5 (G), 4 (B) at the same time = Probability of rolling R and G and B together = Probability of R × Probability of G × Probability of B

= 1/6 × 1/6 × 1/6 = 1/216

Therefore, the probability of rolling a 6 with the red die, a 5 with the green die, and a 4 with the blue die at the same time is 1/216, or approximately 0.46%.

A function is a function that represents the area under a curve. In this case, f is the curve being considered. The function a(x) represents the area under the curve of f from x=0 up to x.

So, if we want to find the area under the curve of f from x=0 up to x=3, we would evaluate a(3) - a(0). This would give us the total area under the curve of f from x=0 to x=3. Similarly, if we have another area function, say b(x), that represents the area under the curve of f from some other starting point (e.g. from x=1), we would use b(x) to find the area under the curve of f from x=1 up to some other x value.
The graph of f, displayed in the figure to the right, represents a function that can be analyzed using various mathematical concepts. In this case, we can consider two area functions for f, denoted as A(x) and B(x), which would allow us to evaluate the areas under the curve of the graph with respect to the x-axis. These area functions can be used to understand properties and behaviors of the function f in different regions of the graph.

Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.

If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

It would take approximately 176,369 pounds of TNT to destroy an abatis made of 72 trees with an average diameter of 30 inches, assuming an average height of 20 feet.

The formula for the volume of a cylinder is V = πr^2h. In this case, we can use the average radius of 15 inches and the average height of 240 inches to estimate the total volume of all 72 trees:

Total volume of all 72 trees = 72 x V

Total volume of all 72 trees = 72 x 169,646

Total volume of all 72 trees ≈ 12,214,832 cubic inches

In this equation, we need to know the density of wood and the REF of TNT. The density of wood can vary depending on the species, but we can use an average value of 0.5 grams per cubic centimeter (g/cm^3). The REF of TNT is 1, by definition. The factor of 0.8 in the equation accounts for losses due to fragmentation and other factors.

Converting the units of volume and density to match, we get:

Total volume of all 72 trees ≈ 200,000,000 cubic centimeters

Density of wood = 0.5 g/cm³

Plugging these values into the equation, we get:

Amount of TNT required = (Total volume of all 72 trees x Density of wood x 0.8) / REF

Amount of TNT required = (200,000,000 x 0.5 x 0.8) / 1

Amount of TNT required = 80,000,000 grams

To convert grams to pounds, we divide by 453.592, which is the number of grams in a pound:

Amount of TNT required = 80,000,000 / 453.592

Amount of TNT required ≈ 176,369 pounds

Answer:

The middle between two numbers is the average of those numbers. So we add those two numbers together and divide by two. And the answer is (1 + 6) / 2 = 3.5

The estimate for the sum of the numbers is 230, and the actual sum of the numbers is 209.

To estimate the sum of the numbers, we can round each number to the nearest ten and then add them together. When rounding off to the nearest tens, we look at the number at the tenth position. If it is five and above, we round it off to the next nearest tens number and if it is below five, we round it off to the previous nearest tens number.

76 rounds to 80   since 6 is above 5
6 rounds to 10 since 6 is above 5
25 rounds to 30 since 5 is located at 5 and above interval
5 rounds to 10 since 5 is located at 5 and above interval
10 rounds to 10 since 0 is below 5
87 rounds to 90 since 7 is above 5

So, the estimate for the sum of the numbers is: 80 + 10 + 30 + 10 + 10 + 90 = 230

To find the actual sum of the numbers, we simply add them together without rounding:
