find the slope of the line of best fit shown below.

The statement is True. It is true that if A and B are 2 × 2 matrices, and det(A) = det(B) = 0, then det(A + B) = 0.

If A and B are matrices such that det(A) = det(B) = 0, then their eigenvalues are 0. It follows that the eigenvalues of A + B are the sums of the eigenvalues of A and B.

The sum of the eigenvalues of A and B is 0 + 0 = 0, and hence the determinant of A + B is 0.30. True.

If A is a 2 × 2 matrix and det(A) ≠ 0, then A is invertible. An invertible matrix has a unique inverse, which means that its determinant is non-zero. If det(A) ≠ 0, then A has an inverse matrix, and hence is invertible.

Conversely, if det(A) = 0, then A is singular and hence not invertible. 31. False. It is not true that if all the entries of an n × n matrix are positive then its determinant is positive.

The statement is true for 2 × 2 matrices but is not true in general for n × n matrices where n > 2. For instance, consider the matrix \begin{pmatrix}1&1&1\\1&1&1\\1&1&1\end{pmatrix} . Its entries are all positive, but its determinant is 0.

Answer:

                 calories

Breakfast: 670  

Lunch:      555

Dinner:     910

Total = 2135 calories

Step-by-step explanation:

Let B, L and D, stand for the calories from Breakfast, Lunch, and Dinner

One day his calories from breakfast were 115 more, than his calories from​ lunch:  

B = L + 115

his calories from dinner were 200 less than twice his calories from lunch.:

D = 2L - 200

total caloric intake from meals was 2135:

B + L + D = 2135

------

We have B and D defined in terms of L from the first two equations, so use them in the third:

B + L + D = 2135

[L+115] + L + [2L-200] = 2135

4L - 85 = 2135

4L = 2220

L = 555 calories

B = L + 115

B = 555 + 115

B = 670 calories

D = 2L - 200

D = 2(555) - 200

D = 910 calories

================

CHECK

Does B + L + D = 2135 calories?

  670 + 555 + 910 = 2135?

 2135 = 2135?   YES

Given the inverse demand function p = 100 - 20q for toasters and a price of $35, we can find the consumer surplus.

First, we'll find the quantity demanded at the given price:

35 = 100 - 20q
20q = 100 - 35
q = (100 - 35) / 20
q = 65 / 20
q = 3.25

Now, to find the consumer surplus, we'll use the formula:

Consumer Surplus = (1/2) × Base × Height

The base represents the quantity (q = 3.25) and the height is the difference between the maximum willingness to pay (p = 100) and the actual price (p = 35).

Consumer Surplus = (1/2) × 3.25 × (100 - 35)
Consumer Surplus = 0.5 × 3.25 × 65
Consumer Surplus = 105.625

So, the consumer surplus is $105.63 when rounded to two decimal places.

The researchers calculated the sodium content (in milligrams) for each order based on Chipotle's published nutrition information. The distribution of sodium content is approximately normal with a mean of 2000 mg and a standard deviation of 500 mg.

In this case, the answer would be the mean sodium content, which is 2000 mg.


First, it's important to understand that a normal distribution is a bell-shaped curve that describes the distribution of a continuous random variable. In this case, the sodium content of Chipotle meals follows a normal distribution.

To calculate the probability of a certain range of sodium content, we can use the z-score formula. The z-score measures the number of standard deviations an observation is from the mean. It is calculated as:

z = (x - mean) / standard deviation

Where x is the specific value we are interested in.
For example, let's say we want to find the probability that a randomly selected meal has a sodium content between 1500 mg and 2500 mg. We can calculate the z-scores for these values:

z1 = (1500 - 2000) / 500 = -1
z2 = (2500 - 2000) / 500 = 1
To find the probability, we can use a standard normal distribution table or a calculator. From the table, we find that the probability of a z-score between -1 and 1 is approximately 0.6827. This means that about 68.27% of the meals have a sodium content between 1500 mg and 2500 mg.

In conclusion, the  answer is the mean sodium content, which is 2000 mg. By using the z-score formula, we can calculate the probability of a certain range of sodium content. In this case, about 68.27% of the meals ordered from Chipotle restaurants have a sodium content between 1500 mg and 2500 mg.

What is Company?

A company is an organization that provides goods or services to its customers in exchange for money. Companies are typically formed by entrepreneurs or business owners who have a vision for a product or service they want to offer. The company is responsible for producing the product or service, marketing it, and then distributing and selling it to the public. Companies must also manage their finances and comply with any legal or regulatory requirements. Companies are typically owned by shareholders who reap the profits of the business. Successful companies often have a strong corporate culture that is reflected in their mission and values.

Pesos that initially was available = 15000 pesos

During year Pesos purchased by company = 25000 pesos

Total pesos at end of the year = 15000 + 25000 pesos = 40000 pesos

Total pesos remaining at end of year = 8000 pesos

Hence pesos consumed in the complete year = 40000 - 8000= 32000 pesos

Step-by-step explanation:

The interest to be paid on $120 at 5% rate for 6 years is $36

Simple interest is the amount paid on a principal amount of money that is borrowed or loaned to someone. It is calculated using the formula: SI = (P × R × T) / 100. Where P is the principal amount, R is the rate and T is the time.

From the question;

P = $120

R = 5%

T = 6years

we shall evaluate for the simple interest as follows:

Simple interest = ($120 × 5 × 6)/ 100

Simple interest = $3600/100

Simple interest = $36

Therefore, the interest to be paid on $120 at 5% rate for 6 years is $36.

You can carve out 150 cubes of side 0.1 m from the given block of wood.

To determine the number of cubes, we need to calculate the volume of the block and the volume of each cube.

The volume of the block is given by:

Volume = length × width × height

Volume = 75 cm × 50 cm × 40 cm

Converting the measurements to meters:

Volume = (75 cm / 100) m × (50 cm / 100) m × (40 cm / 100) m

Volume = 0.75 m × 0.5 m × 0.4 m

Volume = 0.15 m³

The volume of each cube is given by:

Volume of each cube = side³

Volume of each cube = (0.1 m)³

Volume of each cube = 0.001 m³

To find the number of cubes that can be carved out of the block, we divide the volume of the block by the volume of each cube:

Number of cubes = Volume of block / Volume of each cube

Number of cubes = 0.15 m³ / 0.001 m³

Number of cubes = 150

Therefore, you can carve out 150 cubes of side 0.1 m from the given block of wood.

The probability of the sample mean contents of the 10 bottles will depend on the distribution of the contents in the population, the sample size, and the sample mean.

The probability of the sample mean contents of the 10 bottles will depend on the distribution of the contents in the population from which the sample is drawn. If the distribution is normal, then the probability of the sample mean can be calculated using the formula:

P(x) = (1 / √(2πσ^2)) * e^(-(x-μ)^2 / (2σ^2))

Where μ is the population mean, σ is the population standard deviation, and x is the sample mean. The probability of the sample mean will be the area under the normal curve between the sample mean and the population mean.

If the distribution is not normal, then the probability of the sample mean can be calculated using the central limit theorem, which states that the distribution of sample means approaches a normal distribution as the sample size increases. In this case, the probability of the sample mean can be calculated using the formula for the normal distribution, with the sample mean as the mean and the standard error of the mean as the standard deviation.
