What is a complex plane?

A complex plane is formed by complex numbers in a similar manner as the Cartesian coordinate system. But the x axis is made up of real numbers and y axis is made up of imaginary numbers.

A complex number is plotted on a complex plane. In the complex plane the x axis is known as the real axis and the y axis is known as the imaginary axis.

Consider the given complex number.

[tex]z = 3-5i[/tex]

Here, 3 is real number and -5 is imaginary number.

Since 3 is real number hence, move 3 steps in the right direction on x axis. Now, -5 is the imaginary number hence, move 5 steps in the downward direction parallel to the y axis.

The final position is [tex]z = 3-5i[/tex].  

Hence, a complex number is represented on a complex plane.

The weekly goal of 150 minutes of moderate exercise or 75 minutes of intense exercise has increased by 22.9 percent.

The intensity of exercises depends on mostly the amount of energy you have to spend. But the time spent also differs. Intense exercises are basically exercises that require you to expend more energy than how much you spend on normal exercise. Any exercise becomes intense when you spend 70 to 85 percent of your maximum heart rate working out. It is vigorous but you get the same amount of calories burned.

Moderate exercises are the normal ones. These require normal intake of heart rate and energy but take more time. The walk from your house to your college/school or the normal crunches and all you do are perfect examples of moderate exercises.

There is a 0.044% probability of having exactly 8 boys in a sample of 10 births.

Simply put, the probability is the likelihood that something will occur.

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2 (a head or tail).

P(heads) = 1/2 is what we write.

So, X is the proportion of boys among n particular births. Let p represent the likelihood of having a boy at a certain birth.

Here n=10.

Additionally, because male and female births are equally likely, there is a 50% chance of having a boy or a girl.

P(Boy) = P(girl) = 0.5

p = 0.5

Based on the information provided, there will be a defined number of trials (n) of 10, with a constant chance of success (p).

Furthermore, every trial stands alone from the others.

So, with n=10 and p=0.5, X follows a binomial distribution.

The following is the probability function of the binomial distribution for the k number of successes, where x = k.

[tex]\mathrm{P}(\mathrm{X}=\mathrm{k})=(10 C k) 0.5^k(1-0.5)^{10-k}[/tex]

Finding the likelihood of 8 boys in n=10 births is necessary.

P(X=8) = (10C8)0.5⁸(1-0.5)¹⁰⁻⁸

= 45 × 0.0039 × 0.25

P(X = 8) = 0.0438

Therefore, there is a 0.044% probability of having exactly 8 boys in a sample of 10 births.

Step-by-step explanation:

the table was filled correctly already by somebody yesterday.

the important thing to remember is that an arc angle is always measured at the center point of the circle. that is the difference to angles between the intersecting lines of arc segments.

it would be really important that you start doing these things yourself. this hands-on experience of these (really basic) questions is designed to help you get a feeling how these things work together, which makes later topics much easier for you.

please tell me what you don't understand here. you only need to apply common sense. no magic voodoo math formulas or strategies.

FAR = 100° FR = 140° VO = 60° FR+VO = 200°

FAV = 80° FV = 60° RO = 100° FV+RO = 160°

OAV = 100° VO = 60° FR = 140° VO+FR = 200°

OAR = 80° RO = 100° FV = 60° RO+FV = 160°

how did we get the measures of the intercepted arcs ? by counting the 20° segments on the arc. the full circle arc represents 360°. always, for every circle. one time around is one time around and therefore 360°, no matter the size of the circle.

when you stand directly on the south pole of the Earth for 24 hours, you will have rotated the full 360° in that time (one rotation per day). if you stand on the equator for 24 hours, the Earth has taken you on one spin of the full 360°. the difference is the absolute arc length and the necessary speed at which we cover the distance of a full arc length.

every 250 million years our whole sogar system rotates once (by the full 360°) around the center of our galaxy.

the degrees have nothing to do with radius, diameter, area, ... of a circle. only with the relative parts of the circumference. when the minute arm of a clock moved for 15 minutes, then it went 90° around the clock's face. after 60 minutes it went the full 360°, and the cycle starts anew.

so, minutes on a clock or hours of the day are just another way of counting degrees around a circle.

what have we noticed with the sum of the measures of the intercepted arcs ?

many things.

e.g.

they are exactly twice as large as the line angles. 100 to 200. 80 to 160.

the sum of 2 pairs of opposing arc angles is always 360°.

...

so, how will we get the line angles based on the sum of the angles of the intersected arcs ?

we cut the sum of the intersected arc angles in half. 200 to 100. 160 to 80.

A 96% confidence interval for the mean difference in textbook prices at the two online bookstores is (3.22,8.38).

What is a confidence interval?

An estimated range for an unknown parameter is known as a confidence interval. The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.

Here, we have

The mean and standard deviation are M = 5.8 and s = 4.658

To calculate the estimated standard error, we apply

S = [tex]\sqrt{s^2/n}[/tex]

 =[tex]\sqrt{4.658^2/5}[/tex]

= 2.08

The 96% confidence interval is :

CI = x ±t₉₆s/√n

= 5.8 ±2.7764× 2.08/√5

= 5.8±2.58

= (3.22,8.38)

Using the normal distribution formula, we know that the z score that is equivalent to 25 is 1.5.

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.

The characteristics of normal distributions are as follows: Bell-like in its symmetry.

The distribution's mean and median, which are both at its center, are equal.

68 percent of the data, or approximately, falls within one standard deviation of the mean.

So, the formula is used to determine the Z score for a data point x in a normal distribution:

Z = z - mean/standard deviation

Now, use the formula to calculate the z value as follows:

Z = z - mean/standard deviation

Z = 25 - 16/6

Z = 9/6

Z = 3/2

Z = 1.5

Therefore, using the normal distribution formula, we know that the z score that is equivalent to 25 is 1.5.

The percent of the wall does she paint will be;

⇒ 79%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The length of room wall = 8 feet

The width of room wall = 12 feet

The length of windows = 5 feet

The width of windows = 2 feet

Now,

The area of wall = 12 x 8 feet²

                         = 96 feet²

And, The area of windows = 5 x 2 feet²

                                         = 10 feet²

Hence, The area of paints a wall in her bedroom = 96 - 2 (10)

                                                                            = 96 - 20

                                                                            = 76 feet²

So, She paint the wall of area 76 feet².

Since, The area of whole wall = 96 feet²

But, There are two window.

So, The percent of only wall paint of are 76 feet² = 100 x 76 / 96

                                                                            = 79.16%

Thus, The percent of the wall does she paint to the nearest whole percent will be;

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides.

Every triangle is bicentric and convex.

The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane.

Answer:

Step-by-step explanation:

1.Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v. We can use this to get the tangent vectors by taking the respective partial derivatives. Tu=<7, 1, 13> by taking the u derivatives of the components and Tv=<0, -1, 1> by taking the v derivatives of the components.

2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>

3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30. Multiply this by the magnitude of the normal vector to find that Area(S)=30sqrt(294)

4. To integrate, we first must put the initial function in terms of the parameters we found in the first step. Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (sqrt294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6). From here the problem can be integrated like any other double integral, the final answer being 190sqrt(294)

Answer: A

Step-by-step explanation: To solve this problem, we need to use the properties of triangles and the given information to determine the measure of angle C.

First, we can use the fact that angle A is opposite angle C to deduce that angles A and C are congruent (i.e. they have the same measure). This means that the measure of angle C is 25 degrees.

Next, we can use the fact that triangle AABC is isosceles (i.e. it has two sides of equal length) to deduce that angle B is also 25 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, so if angle A is 25 degrees and angle C is 25 degrees, then the remaining angle, angle B, must be 180 - (25 + 25) = 130 degrees.

We can also use the fact that triangle AEFG is isosceles to deduce that angle F is also 100 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, so if angle E is 100 degrees, then the remaining angle, angle F, must be 180 - 100 = 80 degrees.

Finally, we can use the given information that the measure of angle Z is 25 degrees and the measure of angle F is 100 degrees to deduce that the measure of angle X is 180 - (25 + 100) = 55 degrees. This is because the sum of the interior angles of a triangle is 180 degrees, and we have already determined the measures of two of the angles (angles Z and F).

Therefore, the measure of angle C is 25 degrees, which means the correct answer is A) 125 degrees.
