Both values are approximate, rounded to 3 decimal places.

===================================================

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

[tex]S=(n-2)180[/tex]

The polygon given has 7 sides. Substitute 7 for n. Thus:

[tex]S=(7-2)180\\S=5(180)\\S=900[/tex]

The sum of the interior angles is 900 degrees.

Answer:

The expected value for the random variable is 14.16.

Step-by-step explanation:

We are given the following data below;

          Z                               P(Z)                        [tex]Z \times P(Z)[/tex]

          9                               0.16                           1.44

         12                              0.25                             3

         15                              0.36                           5.4

         18                               0.17                           3.06

         21                              0.06                          1.26        

       Total                             1                              14.16        

Now, the expected value for the random variable Z is given by;

          E(Z) = [tex]\sum Z \times P(Z)[/tex]

                  = [tex](9 \times 0.16) + (12 \times 0.25) +......+(21 \times 0.06)[/tex]

                  = 14.16.

Answer:

Step-by-step explanation:

2x - 3y = - 1 ………… Equation 1

y = x - 1 ….……….… Equation 2

To solve using substitution , substitute equation 2 into equation 1

That's

2x - 3( x - 1) = - 1

2x - 3x + 3 = - 1

- x = - 1 - 3

- x = - 4

Multiply through by - 1

We have

Substitute x = 4 , into y = x - 1

We have

y = 4 - 1

y = 3

We have the answers as

x = 4

y = 3

personal budget

Step-by-step explanation:

Drawing up a budget is a good way to plan your expenditure based on how much money you expect to receive. Budgets are often estimates, because you cannot easily include unexpected expenses in a budget. However, you can plan to save some money that you can use in the event of an unexpected expense. Budgeting includes normal monthly budgeting and budgeting for particular expenses, such as an expensive item that you want to buy, a project or a trip overseas.

Answer:

[tex]n = 4.5[/tex]

Step-by-step explanation:

We can turn these words into a real equation. This gets us:

[tex]7n + 3 = 39 - n[/tex]

We want to isolate [tex]n[/tex] on one side of the equation.

Let's add [tex]n[/tex] to both sides:

[tex]7n + n + 3 = -39 - n +n\\\\8n + 3 = -39[/tex]

Subtract 3 from both sides:

[tex]8n+3-3 = 39-3\\\\8n = 36[/tex]

Divide both sides by 8:

[tex]8n \div 8 = 36 \div 8\\\\n=4.5[/tex]

Answer:

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:

[tex]t_{1} = 0.422\pi \pm \pi\cdot i[/tex], [tex]\forall \,i \in \mathbb{N}_{O}[/tex]

[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]

If [tex]\frac{dy}{dx} = -1[/tex], then:

[tex]-1 = -\frac{4}{\tan t}[/tex]

[tex]\tan t = 4[/tex]

Tangent is positive at 1st quadrant and is a function with a periodicity of [tex]\pi[/tex], the set of solutions are:

[tex]t_{1} = 0.422\pi \pm \pi\cdot i[/tex], [tex]\forall \,i \in \mathbb{N}_{O}[/tex]

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

The question is incomplete. Here is the complete question.

ABO blood type is examined in a Taiwanese population, nad the allele frequencies are determined. In the population, f(IA)=0.3, f(IB)=0.15 and f(i)=0.55.

Part A: Assuming Hardy-Weinberg conditions apply, what is the frequency of genotype IAIA? Enter your answer to two decimal places.

Part B: Assuming Hardy-Weinberg conditions apply, what is the frequency of genotype IBIB? Enter your answer to four decimal places.

Part C: Assuming Hardy-Weinberg conditions apply, what is the frequency of genotype IAIB? Enter your answer to two decimal places.

Part D: Assuming Hardy-Weinberg conditions apply, what is the frequency of genotype IAi? Enter your answer to two decimal places.

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

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

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

Answer:

Add 8 to both sides of the equation

m=19

Step-by-step explanation:

The equation given is:

m-8=11

We want to solve the equation for m. To do this, we must isolate m on one side of the equation.

8 is being subtracted from m. The inverse of subtraction is addition. Add 8 to both sides of the equation.

m(-8+8)= 11+8

m= 11+8

m= 19

The step used to solve the equation is adding 8 to both sides and the solution is m=19

[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".

Complex number is expressed as z = x + iy where:
