The set of parametric equations are

[tex]x=\sqrt{t}[/tex]

[tex]y=\sqrt{3+t[/tex]

A parametric equation uses a parameter, which is an independent variable (often represented by the notation t), and dependent variables, which are expressed as continuous functions of the parameter and are independent of other variables.

Using one or more independent variables known as parameters, a parametric equation defines a set of quantities as functions.

Given the equation:

[tex]x= \sqrt[]{y^{2}-3 }[/tex]

Let's find a set of parametric equation for the given equation given the parameter:

[tex]x = \sqrt{t}[/tex]

From the parameter:

[tex]x = \sqrt{t}[/tex]

Now, substitute [tex]\sqrt{t}[/tex] for x in the given equation:

[tex]x=\sqrt{y^2-3} \\\\\sqrt{t} = \sqrt{y^2 - 3} \\\\t=y^2-3\\\\y^2=3+t\\\\y=\sqrt{3+t}[/tex]

Therefore, the set of parametric equations is:

• [tex]x=\sqrt{t}[/tex]

• [tex]y=\sqrt{3+t}[/tex]

The following measures of typical value in a data set would be affected by the error:

Mean: The mean is the sum of all the values divided by the number of values. If one value is significantly different from the rest, it can significantly affect the mean. In this case, the mean would be affected because the value of 5 is much lower than the other values in the data set, which would cause the mean to be lower than it should be.

Median: The median is the middle value in a data set. If the error is low enough, it may not affect the median, but if it is low enough to move the value of 5 to the middle of the data set, the median would be affected.

In conclusion, the mean and median of this data set would be affected by the error of recording the value of 75 as 5.

The mode, mean and median of this data set would be affected by the error of recording the value of 75 as 5.

Given that, a data set represents the math test scores for a class of 20 students. 90, 85, 95, 100, 100, 90, 100, 65, 100, 85, 80, 95, 80, 100, 85, 75, 100, 90, 90, 75 suppose that the last value, 75, was mistakenly recorded as 5.

so, here, due to mistake the mode, mean and the median will be affected.

Adding a data point to the set, or taking one away, can affect the mean, median, and mode.

If we add a data point that's above the mean, or take away a data point that's below the mean, then the mean will increase.

Yes, providing additional information affect responses to a survey question. The difference in the proportion of shoppers who admitted to texting and driving in the two groups is 0.2.

To calculate the difference in the proportion of shoppers who admitted to texting and driving in the two groups, we need to first determine the number of shoppers in each group who admitted to texting and driving.

Let's assume that in Group A, 10 shoppers admitted to texting and driving, while in Group B, 5 shoppers admitted to texting and driving.

Then, we can calculate the proportion of shoppers who admitted to texting and driving in each group by dividing the number of shoppers who admitted to texting and driving by the total number of shoppers in each group:

Proportion in Group A = 10/25 = 0.4

Proportion in Group B = 5/25 = 0.2

The difference in proportions is then:

Difference = Proportion in Group A - Proportion in Group B

Difference = 0.4 - 0.2

Difference = 0.2

Therefore, the difference in the proportion of shoppers who admitted to texting and driving in the two groups (A-B) is 0.2 or 20%.

This suggests that providing additional information about the potential consequences of texting and driving may reduce the proportion of people who admit to engaging in this behavior. However, it's important to note that this study has a small sample size and there may be other factors that influence people's responses to survey questions about texting and driving.

Correct Question :

Does providing additional information affect responses to a survey question? Two statistics students decided to investigate by asking different versions of a question about texting and driving. Fifty mall shoppers were divided into two groups of 25 at random. The first group was asked Version A and the other half were asked Version B. Version A: A lot of people text and drive. Are you one of them? Version B: About 6000 deaths occur per year due to texting and driving. Knowing the potential consequences, do you text and drive? Calculate the difference in the proportion of shoppers who admitted to texting and driving in the two groups (A-B).

1 cubed is 1 so it only makes sense for t=1

The cube root of 1 is 1. So, t = 1.

the unit rate is 6/5 inches per hour, or approximately 1.2 inches per hour.

The unit rate in inches per hour can be found by dividing the amount of rain falling per unit of time by the corresponding unit of time. In this case, we have 4/5 inches falling every 2/3 hours, so we can find the unit rate by dividing 4/5 by 2/3:

(4/5) / (2/3) = (4/5) X (3/2) = 6/5 inches per hour

So the unit rate is 6/5 inches per hour, or approximately 1.2 inches per hour.

Note that the lenght of segment LN = 55.14 (Option D)

This is arrived at using the Chord Bisector Theorem and the  lengths of the sides of a right-angled triangle.

According to the theorem, the line that goes through the circle's center and is perpendicular to the chord also bisects it.

This means that LK (as per the attached image) is the same as MK.

The Right Angle Postulate also means that:

LX = √[KX² - LK²]

LX = √[29² - 9²]

LX = √(841  81)

The correct answer is C. (1, 5) is the ordered pair which is the solution to the system of equations.

A group of two or more equations with the same variables is referred to as a system of equations. The set of values for the variables that make all of the equations in a system of equations true is known as the solution.

The solution to the systems of equations is x = 1 and y = 5.

To solve this system of equations, we can begin by subtracting the two equations to get y - y = -x + 6 - (x + 4).

Simplifying, we get -2x = 2.

Then, dividing both sides of the equation by -2, we get x = -1.

We can now substitute the value of x into either one of the original equations to find the value of y.

If we substitute x = -1 into the first equation, we get y = -1 + 4, which simplifies to y = 3.

Therefore, the solution for this system of equations is x = -1 and y = 3.

Answer:

change the 2w value

Step-by-step explanation:

first, check the equation:

14w + 21 = 14w + 20

when subtracting the 14w from both sides you can see that

21 is NOT EQUAL to 20, making the answer NS.

now, reread the question... create a new equation with ONE solution.

to fix this, we need to change the amount of W's, NOT the amount of constant.

let's try out another number in place of 2w

7 ( 3w + 3 ) = 14w + 20

21 w + 21 = 14w + 20

7 w = -1

w = -1/7

so now it is clear. to change the outcome of the equation, try out another value instead of 2w. Maybe try 3w, 3.5w, or maybe even 1w, or 1.5w .

Answer:

change the 2w

Step-by-step explanation:

=> 7 ( 3w + 3 ) = 14w + 20

=> 21 w + 21 = 14w + 20

=> 7 w = -1

=> w = -1/7

So everything is now evident. Change the value of 2w to anything else to alter the equation's result. Try 3w, 3.5w, or even 1w or 1.5w if you can.

Answer:

70

Step-by-step explanation:

Let x be the number of kangaroos adopted last year.

Twice the number adopted last year is 2x.

So, the number adopted this year is 2x - 24.

Equating this to the given number of kangaroos adopted this year, we have:

2x - 24 = 116

Adding 24 to both sides, we get:

2x = 140

Dividing both sides by 2, we get:

x = 70

So, the number of kangaroos adopted last year was 70.

The unshaded area is 11.5 times bigger than the shaded area.

The area of the circle is given by:

A_circle = πr^2

where;

n this case, r = 10 cm, so:

A_circle = π(10 cm)^2 = 100π cm^2

The area of the semicircle is given by:

A_semicircle = (1/2)πr^2

where;

In this case, the diameter of the semicircle is 8 cm, so the radius is 4 cm:

A_semicircle = (1/2)π(4 cm)^2 = 8π cm^2

To find the area of the shaded region, we need to subtract the area of the semicircle from the area of the circle:

A_shaded = A_circle - A_semicircle

= 100π cm^2 - 8π cm^2

= 92π cm^2

The unshaded area is the area of the circle minus the area of the shaded region:

A_unshaded = A_circle - A_shaded

= 100π cm^2 - 92π cm^2
