B. The experimental probability and the theoretical probability for group X is the same.

Answer:

sin ∠FDE is 12/13

Step-by-step explanation:

The trigonometric ratios will be used to find the value of sin∠FDE

In the given triangle, according to angle FDE

Base = DE = 5

Hypotenuse = DF = 13

Perpendicular = EF = ?

sin ∠FDE = [tex]\frac{perpendicular}{Hypotenuse} = \frac{EF}{DF}[/tex]

We have to find the length of DF first

Pythagoras theorem will be used as the given triangle is a right angled triangle

[tex](Hypotenuse)^2 = (Base)^2+(perpendicular)^2\\(DF)^2 = (DE)^2+(EF)^2\\(13)^2 = (5)^2 + EF^2\\169 = 25+EF^2\\EF^2 = 169-25\\EF^2 = 144\\\sqrt{EF^2} = \sqrt{144}\\EF = 12[/tex]

So,

sin ∠FDE = EF/DF

sin ∠FDE = 12/13

Hence,

sin ∠FDE is 12/13

Answer:

26 is the answer. am I right?

Answer:

Well the answer would be 9.

Step-by-step explanation:

All you have to do is put 6 in the place of X. So the new equation would be 5x2+6-7, and all you do is solve that. So multiply 5 and 2 to get 10, than add 10 to 6 and get 16, 16 minus 7 to get your answer of 9.

Answer:

[tex]\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]

Step-by-step explanation:

We know that:

[tex]\sin(-x)=-m[/tex]

First, since sine is an odd function, we can move the negative outside:

[tex]=-\sin(x)=-m[/tex]

Divide both sides by -1:

[tex]\sin(x)=m[/tex]

We will now use the Pythagorean Identity:

[tex]\cos^2(x)+\sin^2(x)=1[/tex]

Substitute m for sine:

[tex]\cos^2(x)+m^2=1[/tex]

Solve for cosine:

[tex]\cos^2(x)=1-m^2[/tex]

Take the square root of both sides:

[tex]\cos(x)=\pm\sqrt{1-m^2}[/tex]

Since x is an acute angle, cosine will always be positive. Thus:

[tex]\cos(x)=\sqrt{1-m^2}[/tex]

Take the reciprocal of both sides. Hence:

[tex]\frac{1}{\cos(x)}=\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]

Answer:

x = 12

Step-by-step explanation:

Pythagorean triplet

12,16,20

So, the value of x is 12

x + 256 = 400

x = 400 - 256

x = 144

The square of 12 is 144

The question is missing parts. Here is the complete question.

The isosceles triangle below has height AQ of length 3 and base BC of length 2. A point P may be placed anywhere along the line segment AQ.

What is the minimum value of the sum of the lengths of AP, BP and CP?

Answer: The sum is 4.73.

Step-by-step explanation: Height of a triangle is a perpendicualr line linking a vertex and its opposite side.

Because triangle ABC is isosceles, point Q divides the base in 2 equal parts:

BQ = CQ = 1

Suppose QP = x

To calculate minimum value of the sum:

AP = AQ - QP

AP = 3 - x

Since triangles BQP and CQP are congruent and right triangles, use Pythagorean Theorem to figure out the value of BP and CP:

BP = CP = [tex]\sqrt{BQ^{2}+PQ^{2}}[/tex]

BP = [tex]\sqrt{1+x^{2}}[/tex]

Then, sum of AP, BP and CP is

[tex]f(x)=3-x+2\sqrt{1+x^{2}}[/tex]

The minimum value is calculated using first derivative:

[tex]f'=-1+\frac{2x}{\sqrt{x^{2}+1} }[/tex]

The value of x is limited: it can assume value of 0, when P=A and x=3, when P=Q. So, interval is [0,3].

x has value:

[tex]-1+\frac{2x}{\sqrt{x^{2}+1} }=0[/tex]

[tex]2x=\sqrt{x^{2}+1}[/tex]

[tex]4x^{2}-x^{2}-1=0[/tex]

[tex]3x^{2}=1[/tex]

x = ± [tex]\frac{1}{\sqrt{3} }[/tex]

x can't assume negative value because is not in the interval:

x = [tex]\frac{1}{\sqrt{3} }[/tex]

To find the minimum value of the sum, substitute x in the function above:

f([tex]\frac{1}{\sqrt{3} }[/tex])=[tex]3-\frac{1}{\sqrt{3} } +2\sqrt{1+(\frac{1}{\sqrt{3} })^{2} }[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3-\frac{1}{\sqrt{3}}+2(\sqrt{\frac{4}{3} } )[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3-\frac{1}{\sqrt{3}} +\frac{4}{\sqrt{3}}[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3+\frac{3}{\sqrt{3} }[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=4.73[/tex]

The minimum value of the sum of AP, BP and CP is 4.73.

The minimum value of the sum of the lengths of AP, BP and CP is [tex]3 + \frac{\sqrt{3}}{3}[/tex] units.

According to this statement we must determine the sum of the line segment lengths so that a minimum is found. By Pythagorean theorem and given data we have the following expression:

[tex]y = AP + BP + CP[/tex]

[tex]y = 3-x +2\sqrt{x^{2}+1}[/tex] (1)

Now we proceed to find the critical values by performing first and second derivative tests.

FDT

[tex]-1 +\frac{2\cdot x}{\sqrt{x^{2}+1}} = 0[/tex]

[tex]2\cdot x = \sqrt{x^{2}+1}[/tex]

[tex]4\cdot x^{2}-x^{2}-1=0[/tex]

[tex]3\cdot x^{2} = 1[/tex]

[tex]x^{2} = \frac{1}{3}[/tex]

[tex]x = \frac{\sqrt{3}}{3}[/tex]

SDT

[tex]y'' = \frac{2\cdot \sqrt{x^{2}+1}-2\cdot x \cdot \left(\frac{2\cdot x}{\sqrt{x^{2}+1}} \right)}{x^{2}+1}[/tex]

[tex]y'' = \frac{2\cdot x^{2}+2-4\cdot x^{2}}{(x^{2}+1)^{3/2}}[/tex]

[tex]y'' = 2\cdot \frac{1-x^{2}}{(x^{2}+1)^{3/2}}[/tex]

[tex]y'' \approx 0.866[/tex]

A minimum exists when [tex]y'' > 0[/tex], then we conclude that [tex]x = \frac{\sqrt{3}}{3}[/tex] lead to a relative minimum. And by (1) we have the minimum sum:

[tex]y = 3-\frac{\sqrt{3}}{3}+2\sqrt{\frac{4}{3} }[/tex]

[tex]y = 3 - \frac{\sqrt{3}}{3} +\frac{4\sqrt{3}}{3}[/tex]

[tex]y = 3+\frac{\sqrt{3}}{3}[/tex]

The minimum value of the sum of the lengths of AP, BP and CP is [tex]3 + \frac{\sqrt{3}}{3}[/tex] units.

Nota - The statement reports typographical issues, the correct form is presented below:

The isosceles triangle below has height AQ of length 3 and base BC of length 2. A point P may be placed anywhere along the line segment AQ. What is the minimum value of the sum of the lengths of AP, BP and CP.

Answer: A

Step-by-step explanation: In all logic its only a 40 soemthing difference and its a bigger number so my guess is 6.1

The percentage decrease in the number of students will be 6.6%. The correct option is B.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that last year, Springfield Middle School had 620 students. This year, it has 582 students.

The percentage decrease will be calculated as:-

Percentage decrease = ( 620 - 582 ) / 582

Percentage decrease = ( 38 / 582) = 0.0652

Percentage decrease = 0.0652 x 100 = 6.52% ≅ 6.6%

Therefore, the percentage decrease in the number of students will be 6.6%. The correct option is B.

Subtract the time values

131.25 - 119.5 = 11.75

This rounds to 12 when rounding to the nearest whole number.

This means she ran about 12 minutes faster. Since she ran 12 miles, this tells us she ran about 12/12 = 1 minute faster per mile.

The more accurate amount is 11.75/12 = 0.97916666666667 and we can see this is fairly close to 1. If we round to the nearest whole number, then we would get 1.

Answer:

22 hours (B)

Step-by-step explanation:

John's velocity = 55mph

Sally's velocity = 65mph

John's time taken = x

Sally's time taken = x - 4

since they must cover the same distance.

and, distance = vel × time

Sally's vel × time = John's vel × time

55x = 65(x-4)

55x = 65x - 220

-10x = -220

x = 22 hours.

Therefore, Sally catches up after 22 hours

Answer:

Let´s define the variables:

x = number of people in theater A

y = number of people in theater B

We know that a 20% (or 0.2 in decimal form) of the people in theater A answered the survey, then the number of people from theater A that answered the survey is: Na = 0.2*x

We know that a 30% (or 0.3 in decimal form) of the people in theater B answered the survey, then the number of people from theater B that answered the survey is: Nb = 0.3*y

There where 800 people in total (counting from the two theatres)

Then x + y = 800.

A) In this case we have:

Na = Nb

this means that:

0.2*x = 0.3*y

and we also have the equation:

x  + y = 800

To solve this, we need to isolate one variable in one of the equations, i will isolate x in the second equation:

x = 800 - y

And now we can replace this in the other equation to get:

0.2*(800 - y) = 0.3*y

We need to solve this for y:

160 - 0.2*y = 0.3*y

160 = 0.3*y + 0.2*y = 0.5*y

160/0.5 = y = 320

Then there where 320 people in theater B, and:

x + y = 800

x + 320 = 800

x = 800 - 320 = 480

There where 480 people in theather A.

B) Now we have:

x = 440

y = 360

then:

Na = 0.2*440 = 88

In theater A, 88 people answered the survey.

Nb = 0.3*360 = 108

In theater B, 108 people answered the survey.

In total, 88 + 108 = 196 people answered the survey.

Given

P:  ---2 -----,4 ----,6

C: 1200, 1400, 1600

Required

Calculate the fixed cost

First, we need to determine the equation that determines the relationship between P and C

We start by selecting any two corresponding values of P and C

We have that:

[tex](P_1,C_1) = (2,1200)[/tex]

[tex](P_2,C_2) = (6,1600)[/tex]

Calculate the slope, using:

[tex]m = \frac{C_2 - C_1}{P_2 - P_1}[/tex]

[tex]m = \frac{1600 - 1200}{6 - 2}[/tex]

[tex]m = \frac{400}{4}[/tex]

[tex]m = 100[/tex]

The equation is then calculated using:

[tex]C - C_2 = m(P - P_2)[/tex]

Where

[tex]m = 100[/tex] and

[tex](P_2,C_2) = (6,1600)[/tex]

[tex]C - 1600 = 100(P - 6)[/tex]

[tex]C - 1600 = 100P - 600[/tex]

Collect Like Terms

[tex]C = 100P - 600 +1600[/tex]

[tex]C = 100P + 1000[/tex]

From the equation above,

100P represents the amount paid for P phones produced

1000 represents the fixed cost paid

C represents the total amount paid
