The ordered pair that describes the location of V" is (5, -2).

In mathematics, reflection is a transformation in which a geometric figure is mirrored or flipped over a line, plane or point. It is a type of transformation that changes the position of an object without changing its shape or size. Reflection can occur in any number of dimensions, including two-dimensional space (plane), three-dimensional space (solid objects), or even higher dimensions.

The reflection of point V over the x-axis will change the sign of the y-coordinate, so point V' will be located at (-5, -2).

The reflection of point V' over the y-axis will change the sign of the x-coordinate, so point V" will be located at (5, -2).

Therefore, the ordered pair that describes the location of V" is (5, -2).

Step-by-step explanation:

the distance around the field is the perimeter, which is 2(length) + 2(width)

2(150) + 2(100) = 500

2 kilometres = 2000 metres, and 2000/500 = 4

Answer: 4 times

Step-by-step explanation:

Step 1: find the Perimeter

Perimeter = 2L + 2W

= 2(150 meters) + 2(100 meters)

= 500 meters.

Step 2: find how many times the runner would have to run around the perimeter.

2 kilometers = 2000 meters

2000/500=4

The runner would need to go around the field 4 times to run 2km.

If Person A and Person B are playing archery together. the probability that A gets more targets than B is 0.5, or 50%.

The number of targets hit by A and B follows a binomial distribution with parameters n = 201 and n = 200, respectively, and p = 0.5.

To find the probability that A gets more targets than B, we need to find the probability that A hits more than 100 targets (since 100 is the average number of targets hit by each player). We can use the normal approximation to the binomial distribution to do this.

The mean of the difference in the number of targets hit by A and B is:

E(A - B) = E(A) - E(B) = np - np = 0

The variance of the difference in the number of targets hit by A and B is:

Var(A - B) = Var(A) + Var(B) = np(1-p) + np(1-p) = 100

The standard deviation of the difference is then:

SD(A - B) = sqrt(Var(A - B)) = 10

Using the normal distribution approximation, we can standardize the difference in number of targets:

Z = (X - E(A - B)) / SD(A - B)

where X is the number of targets that A hits.

P(A hits more targets than B) = P(A - B > 0)

= P(Z > (0 - 0) / 10)

= P(Z > 0)

= 0.5

Therefore, the probability that A gets more targets than B is 0.5, or 50%. This means that there is an equal chance that A will hit more targets than B as there is that B will hit more targets than A.

x=18.5

The value of x that makes the equation true is -1.

To obtain the value of x, we must first express the equation as seen in the diagram. This gives us:

5x + 6 = 1

Five x was obtained by counting the number of x's that we have in the boxes and the sum of figure 1.

The relative frequency is 8/25.

Relative frequency is a statistical concept that refers to the proportion of times that an event occurs in a given sample or population. It is calculated by dividing the number of times the event occurs by the total number of observations in the sample or population.

Relative frequency is an important concept in probability theory and statistics because it provides a way to estimate the probability of an event occurring based on the observed data. As the sample size increases, the relative frequency becomes a more accurate estimate of the true probability of the event.

Relative frequency is also used in hypothesis testing, where it is used to test whether a particular hypothesis is supported by the data. In this case, the observed relative frequency is compared to the expected relative frequency under the null hypothesis to determine whether the difference between the two is statistically significant.

The total number of spins is 75 and the number of times the spinner landed on 3 is 24.

Therefore, the relative frequency for the event "spin a 3" is:

24/75 = 8/25

So, the relative frequency is 8/25.

The "spin a 3" occurrence has a relative frequency of [tex]\frac{8}{25}[/tex].

A statistical concept known as "relative frequency" describes the percentage of times an event happens in a given sample or population. It is calculated by dividing the total number of observations in the sample or group by the frequency of the event.

Because it offers a method to calculate the probability of an event occurring based on the observed data, relative frequency is a crucial concept in probability theory and statistics. The relative frequency becomes a more precise indicator of the actual probability of the event as sample size rises.

In order to determine whether a specific hypothesis is backed by the data, relative frequency is also used in hypothesis testing. To determine

whether the difference between the two is statistically significant, the observed relative frequency is in this instance compared to the expected relative frequency under the null hypothesis.

There were 75 total spins, and 3 appeared 24 times during those rotations.

As a consequence, the proportional frequency of "spin a 3" is as follows:

Answer:

The image of triangle ABC after the translation 5 units to the right and 5 units down is A'B'C' with vertices at (3, -1), (-2, -6), and (2, -8).

Step-by-step explanation:

To prove that triangle ABC is isosceles, we need to show that at least two of its sides have the same length. We can use the distance formula to calculate the length of each side:

AB = sqrt[(−7−(−2))^2 + (−1−4)^2] = sqrt[25 + 25] = 5sqrt(2)

AC = sqrt[(−3−(−2))^2 + (−3−4)^2] = sqrt[1 + 49] = sqrt(50)

BC = sqrt[(−7−(−3))^2 + (−1−(−3))^2] = sqrt[16 + 4] = 2sqrt(10)

Since AB and AC have different lengths, triangle ABC cannot be equilateral. However, if we compare AB and BC, we see that they have the same length, 5sqrt(2). Therefore, triangle ABC is isosceles.

To find the coordinates of A'B'C' after the translation 5 units to the right and 5 units down, we simply add 5 to the x-coordinates and subtract 5 from the y-coordinates of each vertex. Thus:

A' = (-2+5, 4-5) = (3, -1)

B' = (-7+5, -1-5) = (-2, -6)

C' = (-3+5, -3-5) = (2, -8)

Therefore, the image of triangle ABC after the translation 5 units to the right and 5 units down is A'B'C' with vertices at (3, -1), (-2, -6), and (2, -8).

Check the picture below.

The length L of the curve is approximately 185.35 units.

To find the length of the curve, we first need to find the derivative of the given function:

f'(y) = 1 - (25/32) y^(-2/3)

Next, we need to find the integrand by squaring the derivative and adding 1:

g(y) = √(1 + [1 - (25/32) y^(-2/3)]^2)

Then, we can use this integrand to set up the integral:

L = ∫[0,243] g(y) dy

L= 185.35 units

Using a calculator or software, we can evaluate this integral to find the length L of the curve, which is approximately 185.35 units. Hence the length of curve is  185.35 units

(2x10^n)+(4.02x10^5), what is n?

Step-by-step explanation:

To determine the value of n, we need to rewrite the expression as a number in scientific notation, in the form a x 10^n, where 1 ≤ a < 10.

We can start by factoring out 10^n from both terms:

(2 x 10^n) + (4.02 x 10^5) = 10^n (2 + 4.02 x 10^-5)

Now we need to divide both sides of the equation by (2 + 4.02 x 10^-5):

(2 x 10^n) + (4.02 x 10^5) / (2 + 4.02 x 10^-5) = 10^n

We can simplify the expression on the left side by multiplying the numerator and denominator by 10^5:

(2 x 10^n x 10^5 + 4.02 x 10^5) / (2 x 10^5 + 4.02) = 10^n

Simplifying the numerator:

(2 x 10^(n+5) + 4.02 x 10^5) / (2 x 10^5 + 4.02) = 10^n

Now we can cross-multiply to eliminate the fraction:

(2 x 10^(n+5) + 4.02 x 10^5) = 10^n (2 x 10^5 + 4.02)

Expanding both sides:

2 x 10^(n+5) + 4.02 x 10^5 = 2 x 10^(n+5) + 4.02 x 10^n

Subtracting 2 x 10^(n+5) from both sides:

4.02 x 10^5 = 4.02 x 10^n

Dividing both sides by 4.02:

10^5 = 10^n

Therefore, n = 5.

Using the standard normal distribution table, we can find that the probability of a student typing more than 50 words per minute is 0.2033 or 20.33%.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

It seems like you have given me information about the distribution of typing speed for Mes Fuller's 120 keyboarding students. The distribution is normally distributed with a mean (μ) of 45 words per minute and a standard deviation (σ) of 6 words per minute.

A normal distribution is a continuous probability distribution that is symmetric around the mean value. The mean value is the center of the distribution, and the standard deviation measures the amount of variability or spread of the data.

With this information, we can calculate probabilities for different values of typing speed using the standard normal distribution table or a statistical software program.

For example, if we want to know the probability of a student typing more than 50 words per minute, we can calculate the z-score as follows:

z = (x - μ) / σ = (50 - 45) / 6 = 0.83

therefore, the standard normal distribution table, we can find that the probability of a student typing more than 50 words per minute is 0.2033 or 20.33%.
