About 12% of men and 10% of women are left-handed. if we select a person at random, are the event that the person is male and the event that the person is left-handed independt or associated?

Answers

Answer 1
The probability of being left-handed depends on gender, so gender and left-handedness are NOT independent. They are "associated."
Answer 2

The correct option is A. Gender and handedness are associated because men are more likely to be left-handed than women. This conclusion is drawn from the different probabilities of being left-handed based on gender, indicating an association rather than independence.

A. Gender and handedness are associated because men are more likely to be left-handed than women - - This statement is correct based on the given information. Men have a [tex]12\%[/tex] likelihood of being left-handed compared to women who have a [tex]10\%[/tex] likelihood. This difference shows an association between gender and handedness.

The other incorrect options are:

B. Gender and handedness are independent because all of the possible combinations of each exist - This option is incorrect because independence between two events means that the occurrence of one event does not affect the occurrence of the other. In this case, the probability of being left-handed depends on whether the person is male or female ([tex]12\%[/tex] for men and [tex]10\%[/tex] for women), indicating an association rather than independence.

C. Gender and handedness are associated because the percentage is an estimate - This option is incorrect because the percentages given ([tex]12\%[/tex]for men and [tex]10\%[/tex] for women) are specific probabilities based on data, not estimates. The difference in these probabilities reflects an association between gender and handedness.

D. Gender and handedness are independent because they are both comprised of mutually exclusive events - This option is incorrect because being male or female (gender) and being left-handed (handedness) are not mutually exclusive events. One can be male or female and still be left-handed or right-handed. Independence would require that the probability of being left-handed is the same regardless of gender, which is not the case here.

The complete Question is

About 12%  of men and 10%  of women are left-handed. If a person is selected at random, are the event that the person is male and the event that the person is handed independent or associated?

Choose the correct answer below.

A.  Gender and handedness are associated because men are more likely to be left handed than women

B.  Gender and handedness are independent because all of the possible combinations of each exist

C.  Gender and handedness are associated because the percentage is an estimate

D. Gender and handedness are independent because they are both comprised of mutually exclusive events

if m 6 =50 then find m 11

Answers

Final answer:

The question about finding the value of m 11 based on m 6 cannot be answered with the information provided. Additional context or a specific formula is needed to make a calculation.

Explanation:

It appears that there might be a misunderstanding in the question, as the provided information is not sufficient to determine the value of m 11 based on the value of m 6. The references provided deal with various scientific and mathematical concepts that do not seem directly related to one another and therefore do not give a clear method for calculating m 11 from m 6.

Additional context or information such as a specific formula, sequence, or relationship between m 6 and m 11 would be necessary to provide an accurate answer. Without this information, it's not possible to calculate m 11.

How many triangles can be constructed with angles measuring 80 degrees 80 degrees and 40 degrees

Answers

Zero.

The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.

Answer:

None

Step-by-step explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.


which term best describes the statement given below?
if a = b and b = c then a= c

Answers

Answer:

Syllogism law

Step-by-step explanation:

Given:

a ⇒ b, and b ⇒ c, then a ⇒ c

This is a transitive property and it is also called syllogism law.

For example,

if it rains (a), then the cricket field will be wet (b), this means a ⇒b

If the cricket field wet(b), then the game will be cancelled(c), this means b ⇒c

if it rains (a), then the game will be cancelled(c), this means a ⇒ c

So it is a  valid conclusion. This is called syllogism law.

According to these three facts, which statements are true?

Circle W has center (−3, 0) and radius 8.
Circle V is a translation of circle W, 2 units down.
Circle V is a dilation of circle W with a scale factor of 2.


Select each correct answer. (You can choose more than one).

A. Circle V and circle W are similar.

B. Circle V and circle W have the same center.

C. The radius of circle V is 16.

D. The center of circle V is (−5, 0).

Answers

we have that

1)Circle W has center (−3, 0) and radius 8
the equation of a circle W is
(x+3)²+(y)²=8²

2)Circle V is a translation of circle W, 2 units down.
the center of circle V--------> (-3,0-2)---------> (-3,-2)

3)Circle V is a dilation of circle W with a scale factor of 2.
then the radius circle V is 8*2------> 16 units
the equation of a circle V is
(x+3)²+(y+2)²=16²

therefore

 case A. Circle V and circle W are similar.---------> is correct
because  I can transform circle V to circle W using only translations, rotations and scaling  (In the case of circles, no rotations are necessary).

case B. Circle V and circle W have the same center.-------> is not correct

case C. The radius of circle V is 16.-----------> is correct

case D. The center of circle V is (−5, 0).----------> is not correct


the answer is
 case A. Circle V and circle W are similar.---------> is correct
 case C. The radius of circle V is 16.-----------> is correct

Circle V and Circle W are similar and the radius of Circle V is 16; however, Circle V and Circle W do not have the same center, and the center of Circle V is not (-5, 0), but rather (-3, -2).

Given the information that Circle W has center (-3, 0) and radius 8, and Circle V is a translation of Circle W 2 units down and a dilation with a scale factor of 2, the following statements can be evaluated:

Circle V and Circle W are similar: This statement is true. Both circles maintain their shape after a translation and dilation.Circle V and Circle W have the same center: This statement is false. Translation moves the center of Circle V 2 units down, changing its coordinates.The radius of Circle V is 16: This statement is true. The radius is doubled through the dilation process.The center of Circle V is (-5, 0): This statement is false. The correct center after translation would be (-3, -2).

Find the general solution of the given second-order differential equation. 25y'' − 15y' − 4y = 0

Answers

Consider, pls, this option.

Final answer:

To solve the second-order differential equation 25y'' - 15y' - 4y = 0, we find the characteristic equation and its roots, then express the general solution as a linear combination of terms with the found roots as exponents, resulting in [tex]y(t) = C_1e^{-t/5} + C_2e^{4t/5}.[/tex]

Explanation:

We are given a second-order differential equation with constant coefficients: 25y'' − 15y' − 4y = 0. First, we will look for a characteristic equation that arises from this differential equation to find the general solution.

To find the characteristic equation, we substitute [tex]y = e^{rt}[/tex] (where r is a constant) into our differential equation, replacing y'' with [tex]r^2e^{rt}[/tex], y' with [tex]re^{rt}[/tex], and y with [tex]e^{rt}[/tex]. The equation becomes 25r² − 15r − 4 = 0.

Solving for r, we find the roots of the characteristic equation, which are the values of r that satisfy the equation.

Once we have the roots, which we'll call r₁ and r₂, the general solution to the differential equation is [tex]y = C_1e^{r_1t} + C_2e^{r_2t}[/tex], where C₁ and C₂ are arbitrary constants determined by initial conditions.

To find r₁ and r₂, we factor the characteristic equation:
25r² − 15r − 4 = (5r + 1)(5r - 4) = 0. Hence, r₁ = -1/5 and r₂ = 4/5.

Finally, the general solution to the differential equation is [tex]y(t) = C_1e^{-t/5} + C_2e^{4t/5}.[/tex]

What is the solution (x,y) to the systems of equations above?

Answers

If we multiply the bottom equation by 2 and move x to the right, it becomes:

4y = 2x-38

Now we can substitute it for the 4y in the top equation:

3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3

Then 4y = 2*3-38 => y = -8

So the solution is (3,-8)

Final answer:

The solution to the system of equations 3x + 4y = -23 and 2y - x = -19, found using the elimination method, is (x, y) = (-61, -40).

Explanation:

To solve the system of equations 3x + 4y = -23 and 2y - x = -19, we can use the method of substitution or elimination. Let's use elimination to find the solution for (x, y).

Multiply the second equation by 2 to align the x terms: 2(2y - x) = 2(-19), which gives us 4y - 2x = -38.

Rewrite the equations to align like terms:
  3x + 4y = -23
  -2x + 4y = -38

Add the two equations together to eliminate y: (3x - 2x) + (4y + 4y) = -23 - 38, resulting in x = -61.

Substitute x back into the second original equation: 2y - (-61) = -19, which simplifies to 2y + 61 = -19.

Solve for y by subtracting 61 from both sides: 2y = -80, and then dividing by 2 gives us y = -40.

So, the solution to the system of equations is x = -61 and y = -40.

What is the principal if the amount is $1056,the time is 4 years,and the rate is 8%?

Answers

Use the interest formula, fill in the given values, and solve for the remaining variable.
.. I = Prt
.. 1056 = P*.08*4 . . . . . . . . substitute the given values
.. 1056/0.32 = P = 3300 . . divide by the coefficient of P and evaluate

The principal is $3300.

The principal amount is calculated using the formula for simple interest. By rearranging the formula and inputting the given values for the amount, time, and interest rate, the principal is determined to be $800.

To find the principal if the amount is $1056, the time is 4 years, and the rate is 8%, we can use the formula for simple interest which is:

Amount = Principal + (Principal × Rate × Time)

Rewriting the formula to solve for principal (P), we get:

Principal = Amount ÷ (1 + Rate × Time)

Substituting the given values:

Principal = $1056 ÷ (1 + 0.08 × 4)

Principal = $1056 ÷ (1 + 0.32)

Principal = $1056 ÷ 1.32

Principal = $800

Therefore, the principal is $800.

Gerald graphs the function f(x) = (x – 3)2 – 1. Which statements are true about the graph? Check all that apply. The domain is {x| x ≥ 3}. The range is {y| y ≥ –1}. The function decreases over the interval (–∞, 3). The function increases over the interval (–1, ∞). The axis of symmetry is x = –1. The vertex is (3, –1).

Answers

Hey! Statement 1 is false because the domain of f is all real numbers since the function is quadratic.

Statement 2 is true.

Statement 3 is true because when we graph f, it is a parabola opening upwards with vertex (3, -1). Since it is opening upward, then the value of x from -∞ to 3 is decreasing while increasing from 3 to ∞.

Statement 4 is false because we just stated above that f is decreasing from -∞ to 3. Hence, f is also decreasing from -1 to 3. Hence, f is not increasing from -1 to ∞.

Statement 5 is false because the axis of symmetry is x = 3.

Statement 6 is true.
