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]

⇒ [tex]d=\sqrt{221}[/tex]

Hence we can conclude that the exact distance from the mother fox to her kid fox is option (B) √221 is the correct answer.

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.

Answer:

3 * 10^3 in scientific notation.

3,000 in standard notation.

Step-by-step explanation:

We divide:

3.9 *10^5 / 1.3 * 10^2

= ( 3.9/1.3) * (10^5 / 10^2)

= 3 * 10(5-2)

= 3 * 10^3.

This  equals 3 * 1,000 = 3000.

The number of  times larger the culture sample was compared to a earlier week is, in scientific notation  3.0 × 10³ and in standard notation =  3000

Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed. We denote division by '÷' this symbol.

Given that,

biologist estimated the number of cells in a culture sample as 1.3 × 102

One week later, the number of cells had grown to 3.9 × 105

how many times larger the compared to a week earlier(P) = ?

⇒ P = 3.9 × 105/1.3 × 102

⇒ P = 3.0 × 10³

The quotient in scientific notation = 3.0 × 10³

The quotient in standard notation =  3000

Hence, The results are respectively 3.0 × 10³, 3000

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:

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]

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

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 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).

Answer: It's 2.2 times more expensive to buy the 12-oz can of pop compared to buying it in a 2.00 L bottle

Step-by-step explanation:

You know that:

[tex]1.00\ L = 1.057\ quarts[/tex]

[tex]1.00\ quart=32\ oz[/tex]

Then, you can make the conversion from liters to quarts:

[tex](2.00\ L)(\frac{1.057\ quarts}{1.00\ L})=2.114\ quarts[/tex]

Now, you need to make the conversion from quarts to ounces:

[tex](2.114\ quarts)(\frac{32\ 0z}{1.00\ quart})=67.648\ oz[/tex]

You know that a 12-oz can of soda pop costs 89 cents (which is $0.89). Then, the cost per ounce is:

[tex]\frac{\$0.89}{12}=\$0.074[/tex]

 And a 2.00 L bottle (67.648 oz) of the same variety of soda pop costs $2.29. The cost per ounce is:

[tex]\frac{\$2.29}{67.648}=\$0.033[/tex]

Finally, you must divide $0.074 by $$0.033:

[tex]\frac{\$0.074}\$0.033}=2.2[/tex]

Therefore, It's 2.2 times more expensive to buy the 12-oz can of pop compared to buying it in a 2.00 L bottle.

Buying soda pop in a 12-oz can is about 2.19 times more expensive per ounce than buying it in a 2.00 L bottle.

To compare the cost effectiveness of buying soda pop in different quantities, we first need to convert the volume measurements consistently:

1. Convert 2.00 L to ounces:

  Since 1.00 L = 33.8 oz (using the conversion factor 1.00 L = 1.057 quart and 1 quart = 32 oz),

  [tex]\[ 2.00 \text{ L} = 2.00 \times 33.8 \text{ oz} = 67.6 \text{ oz} \][/tex]

2. Calculate the cost per ounce for the 2.00 L bottle:

  [tex]\[ \text{Cost per ounce} = \frac{\$2.29}{67.6 \text{ oz}} \approx \$0.0339 \text{ per ounce} \][/tex]

3. Calculate the cost for the 12-oz can:

  [tex]\[ \text{Cost of 12-oz can} = \$0.89 \][/tex]

4. Compare the costs:

  [tex]\[ \text{Cost per ounce for the can} = \frac{\$0.89}{12 \text{ oz}} = \$0.0742 \text{ per ounce} \][/tex]

5. Calculate how many times more expensive the can is compared to the bottle:

  [tex]\[ \text{Times more expensive} = \frac{\$0.0742}{\$0.0339} \approx 2.19 \][/tex]

Buying a 12-oz can of soda pop costs approximately $0.0742 per ounce, while buying a 2.00 L bottle costs approximately $0.0339 per ounce. This makes the can approximately 2.19 times more expensive per ounce compared to the bottle.

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!

To find the consecutive odd integers, we need to let x represent the lesser odd integer and solve the equation x + 77 = 6(x+2). The solution is x = 13, so the lesser odd integer is 13 and the greater odd integer is 15.

Let's assume that the lesser consecutive odd integer is x and the greater consecutive odd integer is x+2.

According to the given information, 77 added to the lesser consecutive odd integer is six times the greater consecutive odd integer:

x + 77 = 6(x+2)

Solve the equation:

The lesser consecutive odd integer is 13 and the greater consecutive odd integer is 15.
