A function is shown on the coordinate plane below. For what intervals is the function increasing?

pls hurry

Answers

The function is increasing over the intervals D. -6 < x < -1 and 2 < x < 3 and 4 < x < 6.

When does a function increase?

A function is increasing when the slope of its graph is positive, meaning that its graph is rising from left to right.

In the given coordinate plane, the graph of the function consists of three sections, each of which has an increasing slope.

The first section is from -6 to -1, the second section is from 2 to 3, and the third section is from 4 to 6.

This means that the function is increasing over the intervals -6 < x < -1 and 2 < x < 3 and 4 < x < 6.

To confirm this, we can calculate the slope of the graph in each interval. The slope of the graph between two points (x1,y1) and (x2,y2) is given by (y2-y1)/(x2-x1).

For the first interval, the slope is (3-(-5))/(-1-(-6)) = 8/-5 = -1.6. This is a negative value, which means the graph is decreasing over this interval. For the second interval, the slope is (4-3)/(3-2) = 1/1 = 1. This is a positive value, so the graph is increasing over this interval.

For the third interval, the slope is (6-4)/(4-2) = 2/2 = 1. This is also a positive value, so the graph is increasing over this interval as well.

Therefore, the function is increasing over the intervals -6 < x < -1 and 2 < x < 3 and 4 < x < 6, which is option D.

suppose that the cumulative probability of a company defaulting by years one, two, three and four are 3%, 6.5%, 10%, and 14.5%, respectively. what is the probability of default in the fourth year conditional on no earlier default?

Answers

The probability of default in the fourth year conditional on no earlier default is 14.5%. Option (4).

The probability of default in the fourth year conditional on no earlier default is equal to the probability of default in the fourth year, given that the company did not default in the first three years.

Using the conditional probability formula, we can calculate this probability as follows:

P(Default in Year 4 | No earlier default) = P(Default in Year 4 and No earlier default) / P(No earlier default)

We can calculate the numerator by multiplying the probability of default in the fourth year (14.5%) by the probability of no earlier default, which is the complement of the sum of the probabilities of default in the first three years:

P(Default in Year 4 and No earlier default) = 0.145 x (1 - 0.03 - 0.065 - 0.10) = 0.145 x 0.705 = 0.102

The denominator is simply the probability of no earlier default, which we just calculated:

P(No earlier default) = 1 - 0.03 - 0.065 - 0.10 = 0.705

Now we can substitute these values into the conditional probability formula:

P(Default in Year 4 | No earlier default) = 0.102 / 0.705 = 0.1449, or approximately 14.5%

Therefore, the probability of default in the fourth year conditional on no earlier default is 14.5%.

Answers

Answer:

165 centimeters squared.

Step-by-step explanation:

Since we have 2 shapes combined, we need to split them to make 2 rectangles. Now that we have split these two, we can find their individual areas. We know the formula to find area is L * W = A.

So now we do 15 * 7 = 105 to find the area of the shape on the left.

To find the area of the shape on the right, we do 10 * 6 = 60.

Now we add these to get 165 centimeters squared.

Suppose the measure of <6 can be represented by(3x-9). What equation can be written to solve for the value of x?

What is the value of x?

Answers

Hence, x has a value of 49 as to find x, we add 9 to both sides and divide the result by 3.

what is angle ?

The distance between two intersecting lines or planes is measured in terms of angles. The amount of rotation required to align one of the lines or planes with the other is usually expressed in terms of degrees. The range of an angle is 0 degrees (i.e., no rotation) to 360 degrees (corresponding to a complete rotation).

given

As angles 5 and 7 are a pair of linear angles, their sum must be 180 degrees. Angle 7 therefore has a measure of 180 - 42 = 138 degrees.

We can use the fact that angles 6 and 7 are vertical angles and have the same measure to find the value of x. As a result, we can set the following phrase to indicate that the measure of angle 6 is equal to angle 7:

3x - 9 = 138

In order to find x, we add 9 to both sides and divide the result by 3:

3x = 147

x = 49

Hence, x has a value of 49 as to find x, we add 9 to both sides and divide the result by 3.

The sum of the vectors is then the vector from the tail of the first vector to the head of the final vector. Polygon method of vector additionIn addition, other methods of vector addition, such as the component method, may have limits on the number of vectors that can be added. When using the component method, for example, vectors are broken down into their x- and y-components.

These components are then added to determine the total x- and y-components of the sum vector. The sum vector is then found by combining the x- and y-components. Because of this, the number of vectors that can be added using the component method may be limited by the ability to calculate the individual x- and y-components.

Answers

The condition that will never be required for a nonparametric test is The data are interval. so, the correct option is A).

Nonparametric tests do not assume any specific distribution for the data and do not rely on population parameters such as mean and variance. Therefore, they can be used with data that are nominal, ordinal, or interval, without any assumption about the underlying distribution of the data.

Nonparametric tests rely on the rank ordering of the data rather than their exact values, making them robust to outliers and non-normality.

However, it is important to note that some nonparametric tests may have assumptions about the nature of the data, such as the independence of observations, or the symmetry or continuity of the distribution. These assumptions should be carefully considered before applying a nonparametric test. The correct answer is A).

in how many ways can 4 children be arranged on a 4-animal merry go round if andy is seated on the giraffe

Answers

There are 6 possible arrangements of four children on a 4-animal merry-go-round if Andy is seated on the giraffe.

If Andy is seated on the giraffe in a 4-animal merry-go-round, the arrangement of four children on the merry-go-round can be determined as follows:

Since Andy is already seated on the giraffe, only three children are left to be seated on three other animals. The first child can be seated on any of the three remaining animals. The second child can be seated on either of the two remaining animals since one has already been occupied.

Finally, the third child can be seated on the only remaining animal. Therefore, there are three options for the first child, two options for the second child, and one option for the third child, resulting in 3*2*1 = 6 possible arrangements of four children on a 4-animal merry-go-round if Andy is seated on the giraffe.Answer:6.

Use translations to graph the given function.

Answers

Based on the graph, it looks like the function being graphed is h(x) = √(x+4).

To graph this function using translations, we can start by looking at the graph of the parent function f(x) = √x, which is a basic square root function. The graph of f(x) looks like a half of a parabola, opening up from the origin (0,0), and it includes all points with non-negative x-coordinates.

To graph h(x) = √(x+4), we can start by applying a horizontal shift to the graph of f(x) by replacing x with (x - (-4)) = (x + 4). This will shift the graph of f(x) to the left by 4 units. The resulting function is:

h(x) = √(x+4) = f(x+4)

Next, we can apply a vertical shift of 4 units up, which will move the entire graph of h(x) up by 4 units. The resulting function is:

h(x) = √(x+4) + 4

Using these translations, we can graph h(x) as follows:

Start with the graph of f(x) = √x.

Shift the graph to the left by 4 units by replacing x with (x+4).

Shift the graph up by 4 units by adding 4 to the function.

Plot some points on the resulting graph and connect them with a smooth curve.

The resulting graph should look like the one in the image you provided.

one thousand dollars is deposited in a savings account where the interest is compounded continuously. after 6 years, the balance will be $1370.55 . when will the balance be $1711.03 ? round to the nearest tenth of a year.

Answers

If the balance will be $1370.55 after 6 years, then The balance will be $1711.03 after approximately 14.3 years.

The formula for calculating the balance in a continuously compounded account is:

[tex]A = Pe^{rt}[/tex]

Where:

A = final balance

P = principal (initial deposit)

e = Euler's number (approximately 2.71828)

r = annual interest rate

t = time in years

We know that the initial deposit is $1000 and the balance after 6 years is $1370.55, so we can use these values to solve for the annual interest rate:

[tex]1370.55 = 1000*e^{6r}[/tex]

⇒ [tex]ln(\frac{1370.55}{1000}) = 6r[/tex]

⇒ [tex]r = \frac{ln(\frac{1370.55}{1000})}{6}[/tex]

⇒ [tex]r = 0.0345[/tex]

Now we can use the same formula to find out when the balance will be $1711.03:

[tex]1711.03 = 1000*e^{(0.0345*t)}[/tex]

⇒ [tex]ln(\frac{1711.03}{1000}) = 0.0345*t[/tex]

⇒ [tex]t = \frac{ln(\frac{1711.03}{1000})}{0.0345}[/tex]

⇒ t = 14.3 years.

a pwr core contains about 50000 fuel rods. if the probability to find one defective fuel rod is 0.1%, what is the probability to find 10 defective cores

Answers

The probability of finding 10 defective cores in a sample of 10 power cores is approximately 0.0000161, or about 0.0016%.

Assuming that each fuel rod is independent of each other and that the probability of finding a defective fuel rod is constant at 0.1%, we can model the number of defective fuel rods in a power core with a binomial distribution. Let X be the number of defective fuel rods in one power core, then X follows a binomial distribution with parameters n = 50000 and p = 0.1/100 = 0.001.

To find the probability of finding 10 defective cores, we can use the binomial distribution again, but with a different set of parameters. Let Y be the number of defective cores in a sample of 10 power cores, then Y follows a binomial distribution with parameters n = 10 and p = P(X ≥ 1), where P(X ≥ 1) is the probability of finding at least one defective fuel rod in one power core. We can find P(X ≥ 1) using the complement rule:

P(X ≥ 1) = 1 - P(X = 0)

= 1 - (1 - 0.001)^50000

≈ 0.3935

So, the probability of finding 10 defective cores in a sample of 10 power cores is:

P(Y = 10) = (10 choose 10) * (0.3935)^10 * (1 - 0.3935)^(10 - 10)

How to find the equivalent polynomial related to rational equation

In this problem we find the definition of a rational equation that must transformed into an equivalent polynomial. This can be done by using algebra properties:

2 / (x + 1) - 1 / (x + 2) = 1 / 2

First, use subtraction between fractions of different denominators:

[2 · (x + 2) - (x + 1)] / [(x + 1) · (x + 2)] = 1 / 2

(2 · x + 4 - x - 1) / (x² + 3 · x + 2) = 1 / 2

(x + 3) / (x² + 3 · x + 2) = 1 / 2

Explanation:

How does Rolling-circle replication of plasmids proceed?

Rolling-circle replication of plasmids is a replication mechanism in which the replication process moves in one direction from a single fixed origin. Rolling-circle replication is a process that is often seen in circular plasmid DNA. It is a process that begins with an initiator protein, which is responsible for the nicking of a single DNA strand.The initiation point allows the helix to begin unwinding in one direction.

             As the DNA helix unwinds, replication is carried out in a continuous manner, and the helix is wound up behind it. During the replication process, a new strand is synthesized that is attached to the parent strand's 3' end.

                     Rolling-circle replication, on the other hand, is utilized to produce new plasmids that have a single strand, which can then be employed in other cells for the production of proteins or for research purposes.

Answers

Among the following, "They have the same unusual features" is not a correct comparison among the Z-distribution and all the t-distributions. Option B is the correct answer.

A z-distribution refers to the normal distribution of a standard set of values for a variable. If a variable has a normal distribution with a mean of 0 and a standard deviation of 1, it is said to follow a standard normal distribution, which is also known as a z-distribution.

A t-distribution is a type of probability distribution that is used in statistical analysis when the sample size is small or the population's standard deviation is unknown. T-distributions are used in a variety of statistical tests, including the t-test and the analysis of variance (ANOVA). T-distributions are a family of distributions that resemble the normal distribution, with the tails stretched to either side, based on the number of degrees of freedom.

In general, the t-distribution is less peaked and has heavier tails than the normal distribution. As the degrees of freedom increase, the t-distribution approaches the normal distribution. Thus, Option B "They have the same unusual features" is not a correct comparison among the Z-distribution and all the t-distributions.

A double cheeseburger costs less than a head of broccoli due to lower ingredient costs, a more efficient manufacturing process and some more reasons which are listed below:


Firstly, cheeseburgers are typically made with cheaper ingredients, such as pre-made patties, processed cheese, and pre-made buns. The manufacturing process is also more streamlined and efficient, which further reduces cost. Additionally, the demand for cheeseburgers is typically higher than that for broccoli, which helps to keep prices low.



On the other hand, broccoli requires more labor to harvest and process. It also requires more storage space, which drives up costs. The demand for broccoli is typically lower than for cheeseburgers, which also keeps prices higher.

Answers

Answer:

The rate of production of H2O is 1.35 M/s.

Step-by-step explanation:

To calculate the rate of production of H2O, we need to consider the stoichiometry of the balanced chemical equation:

2 C3H6 + 2 NH3 + 3 O2 → 2 CH2CHCN + 6 H2O

Given the rate of consumption of C3H6 is 0.45 M/s, we can use the mole ratio between C3H6 and H2O to find the rate of production of H2O.

Step 1: Determine the mole ratio of C3H6 to H2O in the balanced equation.

Mole ratio = (moles of H2O produced) / (moles of C3H6 consumed) = 6 / 2 = 3

Step 2: Calculate the rate of production of H2O.

Rate of H2O production = (rate of C3H6 consumption) × (mole ratio) = 0.45 M/s × 3 = 1.35 M/s

So, the rate of production of H2O is 1.35 M/s.
