Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )

Rational numbers are numbers which can be written in the form of a/b  

where a and b are integers.

Irrational numbers are those real numbers which are not rational numbers.

Here, Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.

A composite number is a number divisible by another number than 1 and the number itself.

To find example, a sum of two composite numbers, which is not a composite number, is needed.

Step-by-step explanation:

So, she is saving for a car, and I would times $350 by how many months she needs to wait to save enough for the car. Which is 4 months=T$1400 which is enough.

The probability in a random sample of 55 18 to 29-year-olds that 20 will say they currently have a subscription to Hulu is: 0.087.

This is a binomial distribution problem, where n = 55 and the probability of success (i.e. a person subscribing to Hulu) is p = 0.41.

The probability mass function of a binomial distribution is:

P(X = x) = (nCx) * p^x * (1-p)^(n-x)

where nCx is the binomial coefficient (i.e. the number of ways to choose x items from n items).

So, in this case, we want to find P(X = 20):

P(X = 20) = (55C20) * 0.41^20 * (1-0.41)^(55-20)

P(X = 20) ≈ 0.087

Therefore, the probability that in a random sample of 55 18 to 29-year-olds, 20 will say they currently have a subscription to Hulu is approximately 0.087or 8.7%.

His starting salary is 41250, so we would add that on.  

K = 3000t + 41250.

Step-by-step explanation:

The new function g(x) after shifting upward 66 units and shifting 19 units to the right is g(x) = (x - 19)^2 + 66.

After performing the described transformations on the function f(x) = x^2, the new function g(x) can be determined.

Shift upward 66 units:

To shift the graph of f(x) upward by 66 units, we add 66 to the original function:

f(x) + 66 = x^2 + 66

Shift 19 units to the right:

To shift the graph of f(x) 19 units to the right, we replace x with (x - 19):

f(x - 19) = (x - 19)^2

Combining both transformations, the new function g(x) is:

g(x) = (x - 19)^2 + 66

As a result, the new function g(x) is now g(x) = (x - 19)2 + 66 after being shifted up 66 units and 19 units to the right.

Step-by-step explanation:

A = P(1 + rt)

A = Amount after t months or years

P = Principal or amount saved

r = interest rate = 5.18% = 0.0518

t = time.in years = 18 months

45.455% is  the percentage of distance travelled by her in the train .

In math, what is a distance?

The length of the line segment connecting the two sites is used to measure distance between them.

                               The shortest segment of a line connecting a point to a line will have a length equal to the distance between them.

Distance travelled by bus = 3 miles

Distance travelled by train  = 5 miles

Distance travelled by car = 3 miles

Total distance travelled = 3 + 5 + 3 = 11 miles

the percentage of distance travelled by her in the train = 5/11  * 100

The solution to the system of equations is x = 4 and y = 0. In summary, the correct substitution step for the system is: -4x - 6(x - 4) = -16 .C answer is correct

To solve the given system of equations:

1) y = x - 4

2) -4x - 6y = -16

We can use the substitution method to eliminate one variable and solve for the other.

Step 1: Solve the first equation (1) for y in terms of x.

  y = x - 4

Step 2: Substitute the expression for y from equation (1) into equation (2).

  -4x - 6(x - 4) = -16

Step 3: Simplify and solve for x.

  -4x - 6x + 24 = -16

  -10x + 24 = -16

  -10x = -16 - 24

  -10x = -40

  x = -40 / -10

  x = 4

Step 4: Substitute the value of x back into equation (1) to solve for y.

  y = 4 - 4

  y = 0

Therefore, the solution to the system of equations is x = 4 and y = 0.

In summary, the correct substitution step for the system is:

-4x - 6(x - 4) = -16

By substituting the expression for y from equation (1) into equation (2) and simplifying, we obtain the equation -4x - 6y = -16, which can be further solved to find the values of x and y. C answer is correct

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

Answer:

given the drawing below what is the difference between angle D and angle B​

Step-by-step explanation:

Answer:

1) -7/4

2) 4/7

3) -1/5

Step-by-step explanation:

1) A parallel line would have the same gradient so:

4y = -7x +3
y =\(\frac{-7}{4}x +\frac{3}{4}\)

So a parallel line would have the gradient of \(\frac{-7}{4}\).

2) A perpendicular line would have the inverse reciprocal of the gradient so multiplying the 2 gradients would equal -1 so:

Initially Gradient = -7/4

-7/4 x Perpendicular line = -1

Perpendicular line = -1 x 4/-7

Perpendicular line = 4/7

3) Using the same principle, the perpendicular gradient would be -1/5x

The calculated volume of the prism is 702 cubic cm

From the question, we have the following parameters that can be used in our computation

The trapezoidal prism (see attachment)

The formula of the volume of a trapezoidal prism is

Volume = Base area * Height

Where we have

Base area = 1/2 * (8 + 10) * 6

Evaluate the sum of 8 and 10

Base area = 1/2 * 18 * 6

Evaluate the products of 1/2, 18 and 6

Base area = 54

Also, we have

Height = 13

So, the volume is calculated as

volume = 13 * 54

Evaluate

volume = 702

Hence, the volume of the prism is 702 cubic cm

1. Start off defineing a variable, let’s call it m for months.

2. We know that she saves 20$ every month, so we can just divide the total to find the number of months. But, she withdrew $60. We can add those back to get the total she saved. So we have

280 + 60 = 340

Then we can divide by 20:

340/20 = 17.

The value of such that = k * 180, where k is an integer, is the value at which cotangent is undefinable.

Cotangent, or cot, is one of the six standard trigonometric functions. Cotangent of an angle is defined as the ratio of the adjacent side to the opposite side of a right-angled triangle.

The value of cotangent is undefined when the denominator is zero. This implies that cotangent is undefined at angles where the value of sine is zero.

Since the sine function is periodic and has a period of 360 degrees, the values of sine repeat themselves after every 360 degrees.

For this reason, cotangent is undefined at angles such that θ = k * 180, where k is an integer.

That is, cotangent is undefined at 0°, 180°, 360°, and so on. It is also important to note that cotangent is a periodic function, and its values repeat every 180 degrees.

Therefore, cotangent is undefined at 0° + k * 180°, where k is an integer.

To summarize, the value of Θ at which cotangent is undefined is such that θ = k * 180, where k is an integer.

To answer this question, we have to know the definition of each option:

=> MEAN: this is the average value of a data set which is calculated by adding all the values in the data set and dividing by the number of data points.

=> MEDIAN: this is the value that occurs in the middle of a data set when it is arranged in numerical order. It can be identified form a data set but some times, it has to be calculated.

=> MODE: this is the value that occurs most frequently in a dat set. It is always identified from the data set.

=> RANGE: this is calculated by finding the difference between the greatest value and the least value.

Any term that can be or has to be calculated might not be found in the data set.

As we can see, there is only one term that is not calculated but instead identified, that is the mode.
