[tex]z = 3 + i[/tex] is complex as [tex]a,b\in \mathbb{R}[/tex], [tex]b \neq 0[/tex].

Step-by-step explanation:

A complex number comprehends all numbers of the form:

[tex]z = a+i\cdot b[/tex], [tex]\forall \,a,b\in \mathbb{R}[/tex]

Where [tex]i = \sqrt{-1}[/tex].

In other words, complex numbers are an extension of real numbers.

There is the following classification depending on what values of [tex]a[/tex] and [tex]b[/tex] exist:

Real - [tex]a \in \mathbb{R}[/tex], [tex]b = 0[/tex]

Complex - [tex]a,b\in \mathbb{R}[/tex], [tex]b \neq 0[/tex]  

Pure imaginary - [tex]a = 0[/tex], [tex]b \neq 0[/tex] (The term "nonreal complex" is a synonym for pure imaginary complex)

Let be [tex]z = 3 + i[/tex], which is complex as [tex]a,b\in \mathbb{R}[/tex], [tex]b \neq 0[/tex].

The number contains both real and imaginary parts, hence it is classified as a complex number.

Complex numbers are square roots of negative numbers. They are represented using the letter "i".

[tex]t_{2} = 1.422\pi \pm \pi\cdot i[/tex], [tex]\forall \,i \in \mathbb{N}_{O}[/tex]

Step-by-step explanation:

In the case of parametric equations, the slope of the curve is equal to:

[tex]\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }[/tex]

Where [tex]\frac{dx}{dt}[/tex] and [tex]\frac{dy}{dt}[/tex] are the first derivatives of [tex]x[/tex] and [tex]y[/tex] regarding [tex]t[/tex]. Let be [tex]x(t) =2\cdot \cos t[/tex] and [tex]y(t) = 8\cdot \sin t[/tex], their first derivatives are found:

[tex]\frac{dx}{dt} = -2\cdot \sin t[/tex] and [tex]\frac{dy}{dt} = 8\cdot \cos t[/tex]

Thus, equation for the slope is:

[tex]\frac{dy}{dx} = -\frac{8\cdot \cos t}{2\cdot \sin t}[/tex]

[tex]\frac{dy}{dx} = -\frac{4}{\tan t}[/tex]

Answer:

62.93%

Step-by-step explanation:

Z score is a score used in statistics to measure by how many standard deviations that the raw score is above or below the mean. A positive z score means the raw score is above the mean and a negative z score means the raw score is below the mean. The z score is given as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Given that:

Mean (μ) = 30.05 inches, standard deviation (σ) = 0.3 inches

For x > 29.95

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{29.95-30.05}{0.3} =-0.33[/tex]

From the normal distribution table, P(x > 29.95) = P(z > -0.33) = 1 - P(z < 0.33) = 1 -  0.3707 = 0.6293 = 62.93%

The expression is 7 * 5 + 288/18.

The statement is given as:

Add the product of 7 and 5 to the quotient of 288 and 18.​

Add means +.

So, we have:

The product of 7 and 5 + The quotient of 288 and 18.​

Product means *

#SPJ1

Answer: -0.05 mg/cc*h

Step-by-step explanation:

Here we have the relation:

ConcentrationVsTime.

If we want to find the average rate of change, we can find the slope of a line that passes through the extremes of each interval: (tmin, Cmin) and (tmax, Cmax)

The interval for the time is:

0h to 12h.

The interval for the concentration is:

0.7 mg/cc to 0.1mg/cc.

Then we can use the points:

(0h, 0.7mg/cc) and (12h, 0.1mg/cc)

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Then in this case the slope (or rate of change) is:

a = (0.1mg/cc - 0.7mg/cc)/(12h - 0h) = (-0.6mm/cc)/12h = -0.05 mg/cc*h

Explanation:

I'm assuming you meant to say 16:9 instead of 16:97

The ratio 16:9 means that the horizontal width is 16x units and the height is 9x units. They form the ratio 16x:9x which reduces to 16:9

She wants the tv to be the same size as her old one, so the new tv will also have a diagonal of 42 inches (tv sizes are measured by the length of the diagonal).

Through the pythagorean theorem, we can say

a^2+b^2 = c^2

(16x)^2 + (9x)^2 = (42)^2

256x^2 + 81x^2 = 1764

337x^2 = 1764

x^2 = 1764/337

x^2 = 5.23442136498517 approximately

x = sqrt(5.23442136498517)

x = 2.28788578495194

x = 2.288

--------

This means the dimensions would be

width = 16x = 16*2.288 = 36.608 inches

height = 9x = 9*2.288 = 20.592 inches

both are approximate

Step-by-step explanation:

so first you need to make a equation

since we are trying to find out the amount of rides we can make that stand for x so..

we can first write it as 2.50x

(x = the numbers of rides)

since the entree fee is 17 dollars but they are two kids we have to times 17 by 2 giving us 34 we can add 34 dollars to the equation

34 + 2.50x

alex and kendra have only $51.50 dollars and they cant spend more then that so that means the whole equation has to equal $51.50

34 + 2.50x = 51.50

since we are trying to find the number of rides we can subtract 34 on both sides giving us

2.50x = 51.50 - 34

2.50x = 17.50

then we solve for x which you can divde 2.50 on both sides

x = 17.50 /2.50

x = 7

Answer:

a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is 34.554

Of the turkeys at the 90th percentile for weight, roughly the percentage that  would  be taller than 28 inches 79.37%

Step-by-step explanation:

Given that:

For a population of turkeys at a farm, the correlation found between the weights and heights of turkeys is r = 0.64

the average weight in pounds [tex]\overline x[/tex] = 17

the standard deviation of the weight in pounds [tex]S_x[/tex] = 5

the average height in inches [tex]\overline y[/tex] = 28

the standard deviation of the height in inches [tex]S_y[/tex] = 8

Also, given that the weight and height both roughly follow the normal curve

For this study , the slope of the regression line can be expressed as :

[tex]\beta_1 = r \times ( \dfrac{S_y}{S_x})[/tex]

[tex]\beta_1 = 0.64 \times ( \dfrac{8}{5})[/tex]

[tex]\beta_1 = 0.64 \times 1.6[/tex]

[tex]\beta_1 = 1.024[/tex]

To the intercept of the regression line, we have the following equation

[tex]\beta_o = \overline y - \beta_1 \overline x[/tex]

replacing the values:

[tex]\beta_o = 28 -(1.024)(17)[/tex]

[tex]\beta_o = 28 -17.408[/tex]

[tex]\beta_o = 10.592[/tex]

However, the regression line needed for this study can be computed as:

[tex]\hat Y = \beta_o + \beta_1 X[/tex]

[tex]\hat Y = 10.592 + 1.024 X[/tex]

Recall that;

both the weight and height roughly follow the normal curve

As such, the weight related to 90th percentile can be determined as shown below.

Using the Excel Function at 90th percentile, which can be computed as:

(=Normsinv (0.90) ; we have the desired value of 1.28

∴

[tex]\dfrac{X - \overline x}{s_x } = 1.28[/tex]

[tex]\dfrac{X - 17}{5} = 1.28[/tex]

[tex]X - 17 = 6.4[/tex]

X = 6.4 + 17

X = 23.4

The predicted height [tex]\hat Y = 10.592 + 1.024 X[/tex]

where; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.9616[/tex]

[tex]\hat Y = 34.5536[/tex]

Now; the probability of predicted height less than 34.5536 can be computed as:

[tex]P(Y < 34.5536) = P( \dfrac{Y - \overline y }{S_y} < \dfrac{34.5536-28}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< \dfrac{6.5536}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< 0.8192)[/tex]

From the Z tables;

P(Y < 34.5536) =0.7937

Hence,  a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is :

[tex]\hat Y = 10.592 + 1.024 X[/tex]

where; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.962[/tex]

[tex]\mathbf{\hat Y = 34.554}[/tex]

Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?

i.e

P(Y >28) = 1 - P (Y< 28)

[tex]P(Y >28) = 1 - P( Z < \dfrac{28 - 34.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < \dfrac{-6.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < -0.8193)[/tex]

From the Z tables,

[tex]P(Y >28) = 1 - 0.2063[/tex]

[tex]\mathbf{P(Y >28) = 0.7937}[/tex]

= 79.37%

Part I: What is the frequency of type AB blood in this population? Enter your answer to two decimal places.

Part J: What is the frequency of type O blood in this population? Enter your answer to four decimal places.

Answer: Part A: f(IAIA) = 0.09

              Part B: f(IBIB) = 0.0225

              Part C: f(IAIB) = 0.05

              Part D: f(IAi) = 0.16

              Part E: f(IBi) = 0.082

              Part F: f(ii) = 0.3025

              Part G: f(type A) = 0.25

              Part H: f(type B) = 0.1050

              Part I: f(type AB) = 0.05

              Part J: f(type O) = 0.3025

Step-by-step explanation: A population in Hardy-Weinberg equilibrium is a population with a constant value in the population's allele frequency.

In the population of Taiwan, frequencies are:

A: Frequency for genotype IAIA: Frequency of allele A is 0.3, then for genotype IAIA:

f(IAIA) = 0.3²

f(IAIA) = 0.09

B: Frequency of allele B is 0.15. Then, for genotype IBIB:

f(IBIB) = 0.15²

f(IBIB) = 0.0225

C: Frequency for genotype IAIB:

f(IAIB) = 0.3*0.15

f(IAIB) = 0.05

D: Frequency for genotype IAi:

f(IAi) = 0.3*0.55

f(IAi) = 0.16

E: frequency for genotype IBi:

f(IBi) = 0.15*0.55

f(IBi) = 0.082

F: frequency for allele i is 0.55. Then, for genotype ii:

f(ii) = 0.55²

f(ii) = 0.3025

Individuals with type A blood can be IAIA or IAi. Using probability's "OR" rule:

f(type A) = 0.09 + 0.165

f(type A) = 0.25

The same happens to individual with type B blood:

f(type B) = 0.0225 + 0.0825

f(type B) = 0.105

Since blood type is a codominance, i.e., allele A and allele B are expressed, frequency of type AB is equal to frequency of genotype AB:

f(type AB) = 0.3*0.15

f(type AB) = 0.05

Frequency for type O is:

f(type O) = 0.55²

f(type O) = 0.3025
