Answer:

(-2, 1)

Step-by-step explanation:

Hi Juliadayx! How are you?

Well, maybe you already heard about the domain and the range of a function.  

The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.

In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).

I hope I've been helpful!

Answer:

Step-by-step explanation: Im pretty sure they are asking you for the slope so it would be y = 0.5x

Answer:

0.5

Step-by-step explanation:

The unit rate is the number of units obtained in the "y" variable per unit obtained in the "x" variable. This behavior is observed in proportional relationships. For example: imagine that we know that the price for 5 pencils is $2.5. Since this is a proportional relationship, the unit rate will be the price of 1 single pencil, that is obtained by dividing 2.5 / 5 = 0.5.

In this case we also know that the graph passes through the point (1, 0.5), so the unit rate is given in that point.  :)

To calculate the length of each section when dividing a rope into 4 parts, the total length of the rope is divided by 4. For a 15-foot rope, each section is 3.75 feet long. If a 30-foot rope is used, each section would be 7.5 feet long.

To find out the length of each section of rope when a 15-foot rope is cut into 4 equal sections, we simply divide the total length of the rope by the number of sections.

Therefore, each section would be: 15 feet ÷ 4 = 3.75 feet long.

Now, if twice the length of this nylon rope is used, that means we would have a 30-foot rope instead of a 15-foot rope. Again, if we cut this 30-foot rope into 4 equal sections, each section would then be: 30 feet ÷ 4 = 7.5 feet long.

Answer:

k = Y*A/L

Step-by-step explanation:

We can apply the Law of Hooke in order to explain the problem.

If we define k = F / ΔL  and the Y = S / δ

Where S is the uniaxial stress: S =  F / A   (i)

and δ is the strain: δ = ΔL / L   (ii)

ΔL is the change in length

we can combine the equations i and ii as follows

Y = (F / A) / (ΔL / L) = (F * L) / (A * ΔL)   (iii)

if k = F / ΔL the equation iii results

Y = k * (L / A)  ⇒   k = Y*(A / L)

The spring constant of a metal bar for low values of tensile strain can be determined using Hooke's Law. It is given by the formula k = (A * Y) / L, where A is the cross-sectional area, Y is the Young's modulus of the material, and L is the initial length of the bar.

The 'spring constant' of a metal bar for low values of tensile strain can be determined using Hooke's Law, which relates the applied force to the resulting elongation. In this case, the elongation is equivalent to the tensile strain.

Therefore, the spring constant of a metal bar for low values of tensile strain is

k = (A * Y) / L

  5x -2y = -10

Step-by-step explanation:

Slope-intercept form of the equation for a line is ...

  y = mx + b . . . . where m is the slope and b is the y-intercept.

Using the given numbers, the equation is ...

  y = 5/2x + 5

Answer:

Step-by-step explanation:

If you consider the English-language meaning of the description of the distances, you can see there might be several ways you could write an equation that says the same thing. Some of them are ...

  laura's distance = max's distance + 2 3/4 feet

  laura's distance - max's distance = 2 3/4 feet

  laura's distance - 2 3/4 feet = max's distance

The first of these equations is shown as an answer above. The last of these equations gives max's distance directly, so is the most useful for finding that value.

  laura's distance - 2 3/4 feet = max's distance

  8 1/6 feet - 2 3/4 feet = max's distance

  5 5/12 feet = max's distance . . . . . . do the arithmetic

_____

Describing addition and subtraction of mixed numbers is beyond the scope of this answer. Many calculators can work with fractions directly, in case you cannot do it by hand.

Max's paper airplane flew 65/12 feet.

To solve this problem,

we need to set up an equation to represent the relationship between Laura's paper airplane and Max's paper airplane. Let's use the variable 'x' to represent the distance Max's paper airplane flew.

We know that Laura's airplane flew 8 1/6 feet and that was 2 3/4 feet farther than Max's airplane.

So the equation is: x + 2 3/4 = 8 1/6. To solve the equation, we need to subtract 2 3/4 from both sides: x = 8 1/6 - 2 3/4.

Now, let's convert the mixed numbers to improper fractions. 8 1/6 = 49/6 and 2 3/4 = 11/4.

So the equation becomes: x = 49/6 - 11/4.

To subtract fractions, we need a common denominator, which in this case is 12. Multiplying the fractions,

we get x = 98/12 - 33/12. Subtracting the numerators, we have x = 65/12.

Therefore, Max's paper airplane flew 65/12 feet.

Answer:

A. 0.1654

Step-by-step explanation:

Let's call :

D: The event in which a person has a disease

ND: The event in which a person doesn't have a disease

TD: The event in which the test result is positive

Therefore, the probability that a person has the disease given that his test result is positive is calculated as:

P(D/TD) =P(D∩TD)/P(TD)

Where P(D∩TD) is the probability that a person has a disease and the test result is positive and P(TD) is the probability that the test result is positive.

So, The probability P(D∩TD) is calculated as a multiplication of:

P(D∩TD)=0.1% * 99% = 0.099%

Because 0.1% is the percentage of population that actually has the disease and 99% is the probability that the test detect the disease when it is present.

Then, for calculate the probability P(TD) we need to sum the probability of the following cases:

P(ND∩TD)= (100%-0.1%)*0.5%=0.4995%

Because (100%-0.1%) is the percentage of population that doesn't have the disease and 0.5% is the probability that the test imply that a person has the disease when it is not present.

So, P(TD) is calculated as:

P(TD) = P(D∩TD) + P(ND∩TD)

P(TD) = 0.099% + 0.4995%

P(TD) = 0.5985%

Finally, P(D/TD) is:

[tex]P(D/TD) =\frac{0.099%}{0.5985%}=0.1654[/tex]

A regression coefficient is the same thing as the slope of the line of the regression equation.

Step-by-step explanation:

The equation for the regression coefficient that you'll find on the AP Statistics test is: B1 = b1 = Σ [ (xi – x)(yi – y) ] / Σ [ (xi – x)2].

To find a regression equation, you plot the data on a scatter plot, draw an approximate line of best fit, calculate its slope and y-intercept, and then write the equation. Alternatively, you can use statistical software or a calculator's regression function to find the most accurate equation.

To find a regression equation, one can follow these steps:

An example regression equation from sample data might look like this: ŷ = 173.51 + 4.83x, where x is the independent variable and ŷ is the predicted value of the dependent variable, y.

It is crucial to remember that regression equations predict outcomes for the variables within the given data set, but they should not be extrapolated beyond the scope of the available data. Variability in real data means that different samples might yield different regression equations, which is why it is important to consider the goodness of fit, such as the correlation coefficient or the coefficient of determination (r2).

The exact distance from the mother fox to her kid fox is option (B) √221 is the correct answer.

It is the length of the straight line connecting these points in the coordinate plane. This distance can never be negative, therefore we take the absolute value while finding the distance between two given points. The distance formula is an application of the Pythagorean theorem.

For the given situation,

The mother fox is at (x₁, y₁) = (-7,7)

The kid fox is at (x₂, y₂) = (7,2)

The formula of distance between two points is

[tex]d=\sqrt{(x_{2} -x_{1} )^{2} +{(y_{2}-y_{1})^{2}}[/tex]

⇒ [tex]d=\sqrt{(7-(-7) )^{2} +{(2-7)^{2}}[/tex]

⇒ [tex]d=\sqrt{(7+7)^{2} +{(2-7)^{2}}[/tex]

⇒ [tex]d=\sqrt{(14)^{2} +{(-5)^{2}}[/tex]

⇒ [tex]d=\sqrt{196+25}[/tex]

The question's subject is ambiguous but appears to be about wildlife biology, focusing on the relationship between mother foxes and their kits or chimpanzee social behavior. The exact distance between a mother fox and her offspring is not provided and would vary in the wild, but close proximity is typical for maternal care.

It seems there might be some confusion in the question as it refers to a 'mother fox' but the given information relates to chimpanzees and red foxes in different contexts. If the question pertains to the actual distance a mother fox might maintain from her kit (assuming 'kit' is used to mean 'offspring'), it is not specified in the provided information. The exact distance would depend on numerous factors including the age of the kit and the environmental circumstances. However, in the natural setting, foxes, which are eutherian mammals, may stay close to their offspring to provide nourishment and protection. In the case of chimpanzees, mothers and offspring maintain close physical proximity especially in the juvenile years, as offspring are dependent on the mother for care and learning social skills.
