Derrick does 29 push-ups in the morning and 36 more push-ups in the evening. If he does the same number of push-ups every day of the week for 4 weeks, about how many push-ups will he do in all?

Answer:

The correct answer is 0.5

Option D is correct

Step-by-step explanation:

The area to the right of the mean in a normal distribution is indicated by which of the following?

The correct answer is 0.5

Option D is correct

Reason: The half of the data lie to left of mean and half of the data to the right of mean. So area to the right of mean is 0.5

In a normal distribution bell-shaped curve, the area to the right of the mean has been 0.5. Thus, option D is correct.

The probability for the continuous range of values can be given by normal distribution. The distribution has been defined in terms of the graph.

The normal distribution has been based on the mean values and standard deviation. The normal curve has been bell-shaped, and the increase in the standard deviation results in the spreading out of the curve.

The normal curve has the characteristic value of 1 for the area under the curve. The curve has been central to the mean. The area to the left of the mean has been 0.5, and the area to the right of the mean has been 0.5.

In a normal distribution bell-shaped curve, the area to the right of the mean has been 0.5. Thus, option D is correct.

Answer:

84

Step-by-step explanation:

One way to solve proportions is to cross multiply. If we name the unknown value x, then we can see that:

2x = 12(14)

2x = 168

x = 84

Another way to solve proportions is to ask, what number did you multiply the first numerator by to get the second numerator. In this case, what do you have to multiply 2 with to get 14. The answer is 7, so that means you must also multiply the first denominator by 7 to get the second denominator, or in this case, the unknown value. 12 x 7 = 84, so the missing number is 84.

The true statement about the function is that (c) the domain of f(x) consists of all values of x such that g(x) does not equal 0 and h(x) does not equal 0.

The complete question is added at the end of this solution

From the complete question, we have the following equation

f(x) = g(x)/h(x)

The above equation means that

The function f(x) is the quotient of the functions g(x) and h(x)

For the function f(x) to have real values, the function h(x) must not equal 0

i.e. h(x) ≠ 0

This is so because

A number or an expression divided by 0 is not a real number

Hence, the true statement is that the domain of f(x) consists of all values of x where h(x) does not equal 0.

Answer:

x=9.717

y=18.275

Step-by-step explanation:

First solve for x and then use x to help you solve for y

The correct answer is option (D) "The graph shifts 7 units right and 8 units down".Explanation:To solve the given question, we need to use the rules for vertical and horizontal shifts, which are as follows:

Vertical Shift: y=f(x)+a moves the graph of f(x) upward if a > 0 and downward if a < 0.Horizontal Shift: y=f(x+a) moves the graph of f(x) left if a > 0 and right if a < 0.Now, let's transform the function f(x) into function g(x) and determine the shift required.The transformation of f(x) to g(x) is: g(x) = f(x - a) + bwhere a = horizontal shift and b = vertical shiftThe equation of the given functions is:f(x) = 1/(x − 2) and g(x) = 1/(x^(5/9))Let's set the equation of function f(x) in the standard form:y = 1/(x - 2)and the equation of function g(x) in the standard form:y = 1/(x^(5/9))

Now, we can observe that:To transform the graph of f(x) onto the graph of g(x), we need to shift the graph of f(x) right by 7 units and down by 8 units, which is given in option (D).Hence, the correct option is (D) "The graph shifts 7 units right and 8 units down".

The graph shifts 7 units right and 8 units down is the statement that describes the transformation of the graph of function f onto the graph of function g.Conclusion:Thus, we have determined the correct answer with an explanation and concluded that the correct option is (D) "The graph shifts 7 units right and 8 units down".

The three consecutive odd integers are 47, 49, and 51. The third number is 51, so the answer is (d) 51.


Let's represent the first odd integer as x. Then, the next two consecutive odd integers would be x + 2 and x + 4.

According to the problem, the sum of these three consecutive odd integers is 147:

x + (x + 2) + (x + 4) = 147

We simplify and solve for x, which gives us the value of the first integer.

Simplifying and solving for x, we get:

3x + 6 = 147

3x = 141

The  trains are side by side after approximately 15 seconds.Option (b) is correct.

The position of the first train is given by the function:

\($$y_1 = 14t^2$$\)

The position of the second train is given by the function:

\($$y_2 = 130t + 1200$$\)

To find the time when the trains are side by side, we need to solve for the value of t that makes y1 = y2. Thus, we can set the two equations equal to each other:

\($$14t^2 = 130t + 1200$$\)

Rearranging the terms, we get:

\($$14t^2 - 130t - 1200 = 0$$\)

Dividing both sides by 2 to simplify the coefficients, we get:

\($7t^2 - 65t - 600 = 0$$\)

We can use the quadratic formula to solve for t:

\($t = \frac{-(-65) \pm \sqrt{(-65)^2 - 4(7)(-600)}}{2(7)} = \frac{65 \pm \sqrt{4225 + 16800}}{14}$$\)

Simplifying the expression under the square root, we get:

\($$\sqrt{21025} = 145$$\)

So the solutions are:

\($t_1 = \frac{65 + 145}{14}=15$$\)

\($t_2 = \frac{65 - 145}{14} \approx -5.71$$\)

Since time cannot be negative, we discard t2 as an extraneous solution. Thus, the viable time when the trains are side by side is:

\($t = t_1 =15$$\)

Therefore, the trains are side by side after approximately 15 seconds.

These values of h and k are specific to the given system of equations and may not apply to other systems.

(a) The system has no solution when h = 16.
(b) The system has a unique solution for any value of h ≠ 16.
(c) The system has many solutions when h = 16.

To determine the values of h and k that result in different solutions for the given system of equations, let's analyze the coefficient matrix of the system:
```
2   4
8   h
```
(a) To have no solution, the coefficient matrix must be inconsistent. This occurs when the determinant of the matrix is zero. In this case, the determinant is 2h - 32. So, to have no solution, we need 2h - 32 = 0. Solving this equation, we find h = 16. Therefore, the system has no solution when h = 16.

(b) To have a unique solution, the coefficient matrix must be consistent and have a non-zero determinant. This means that 2h - 32 ≠ 0. Since the determinant of the coefficient matrix is 2h - 32, we can conclude that the system has a unique solution for any value of h such that h ≠ 16.
(c) To have many solutions, the coefficient matrix must be consistent and have a determinant of zero. In this case, we need 2h - 32 = 0, which gives us h = 16. Therefore, the system has many solutions when h = 16.

The set {v₁, v₂, v₃, v₄} defined in R⁵ must be linearly independent for the following reasons:

a) Linear Independence

b) Dimensions of the space

This set, containing four vectors, must be independent in R⁵  for satisfying the following properties.

Linear Independence:

We call a set of vectors linearly independent if none of the vectors in the set can ever express any other vectors as a linear combination of the given vectors.

Dimensions:

The given set exists in a 5-Dimensional vector space, which means that any set of vectors in R⁵ can have 5 linearly independent vectors at the maximum.

If {v₁, v₂, v₃, v₄} were linearly dependent, then it would mean that one of them could be linearly expressed by the others. This will reduce the effective dimensions of the set. But it is given that the set exists in R⁵.

Now, if we have the set {v₁, v₂, v₃} as linearly independent and  v₄ is not in the span of {v₁, v₂, v₃}, it would mean that we cannot express v₄ as a linear combination of v₁, v₂, and v₃.

This fact ultimately gives us back the fact that all vectors [v₁, v₂, v₃,v₄} are linearly independent because v₄ then introduces a new direction, which cannot be specified by the existing vectors.

So, to summarise, the set {v₁, v₂, v₃, v₄} defined in R⁵ must be linearly independent to maintain the full-dimensionality of vector space.

Answer:

The surface area of the triangular prism is \(624cm^{2}\)

Step-by-step explanation:

First find the area of the triangle.

The formula of the area of triangle is: \(\frac{1}{2} * h*b\)

h=height

b=base or width.

\(\frac{1}{2}*16*12\)

But, since we have two triangles we can skip the \(\frac{1}{2}\) because \(2*\frac{1}{2} =1\).

\(16*12=192\), that is the area of the two triangles combined.

Now let's find the area of the rectangles. I'll start with the diagonal one.

The formula of the area of the rectangle is: \(h*b\).

\(20*9=180\).

The next rectangle.

\(9*16=144\)

The final rectangle.

\(12*9=108\)

Now combine all the areas to find the surface area of the triangular prism.

\(192+180+144+108=624\)

The surface area of the triangular prism is \(624cm^{2}\)

The big-O estimate for the number of operations in this segment of the algorithm is O(n), where n represents the input size.

To give a big-O estimate for the number of operations used in a segment of an algorithm, we need more specific information about the segment and its complexity. Big-O notation provides an upper bound on the growth rate of the algorithm as the input size increases.

If the segment involves a loop that iterates n times, and each iteration performs a constant number of operations (additions or multiplications), then the complexity would be O(n). This means that the number of operations increases linearly with the input size.

However, without further details about the specific segment or the algorithm's overall structure, it is challenging to provide a more accurate estimation. The complexity analysis requires examining the code's control flow and considering factors such as nested loops or recursion.

In summary, the big-O estimate for the number of operations in this segment of the algorithm is O(n), where n represents the input size.

37,840 is the fox population predicted to be in the year 2019.

What is a growth rate?

The country, territory, or geographic area's yearly average rate of change in population size over a certain time period. It expresses the proportion, usually multiplied by 100, between the annual growth in population size and the total population for that year.

Here, we have

A growth rate of 9% per year means that at the end of each year, the population is 1.09 times what it was at the start of the year.  

We keep this up for t years, starting with an initial population of 20,700, and get

P(n) = 20,700 (1.09)ⁿ

n = years since 2012, when the population was 20,700

For the year 2019,

n = 2019 - 2012 = 7

P(7) = 20,700 (1.09)⁷ ≅ 37,840

Hence, 37,840 is the fox population predicted to be in the year 2019.
