Answer:

Step-by-step explanation:

we have given that emails arrives at the server at the rate of 10 per hour means [tex]\frac{10}{60}=0.166[/tex]  per minute

we have to find the probability that the time difference between the two email is more than 2 minute

so probability [tex]P\left ( X> 2 \right )=e^{-2\lambda }=e^{-2\times 0.166}=0.7166[/tex]

The probability that the time between two consecutive emails arriving at the server is more than two minutes is 0.72 (or 72%).

Given:

- Average rate of email arrivals [tex](\( \lambda \))[/tex] = 10 per hour

1. Understanding the Poisson Process:

  - In a Poisson process, the time between events (in this case, email arrivals) follows an exponential distribution.

  - If [tex]\( \lambda \)[/tex] is the average rate of events per unit time (here, per hour), the time between events (interarrival time) T follows an exponential distribution with parameter [tex]\( \lambda \)[/tex].

2. Parameter Conversion:

  - Since [tex]\( \lambda = 10 \)[/tex] emails per hour, we convert this to the rate per minute:

 [tex]\[ \lambda_{\text{minute}} = \frac{10}{60} = \frac{1}{6} \text{ emails per minute} \][/tex]

3. Probability Calculation:

  - We are interested in the probability that the time between two consecutive emails is more than two minutes.

  - Let X denote the time between two consecutive emails. X follows an exponential distribution with rate [tex]\( \lambda_{\text{minute}} = \frac{1}{6} \)[/tex].

[tex]\[ P(X > 2) = e^{-\lambda_{\text{minute}} \cdot 2} \][/tex]

  Substitute [tex]\( \lambda_{\text{minute}} = \frac{1}{6} \)[/tex]:

 [tex]\[ P(X > 2) = e^{-\frac{1}{6} \cdot 2} \] \[ P(X > 2) = e^{-\frac{1}{3}} \][/tex]

4. Calculating the Probability:

  - Use a calculator to find [tex]\( e^{-\frac{1}{3}} \)[/tex].

[tex]\[ e^{-\frac{1}{3}} \approx 0.7165 \][/tex]

  Therefore, the probability that the time between two consecutive emails is more than two minutes is approximately 0.72 (rounded to two decimal places).

This result aligns with the characteristics of a Poisson process with an average arrival rate of 10 emails per hour.

the first one

the degree of the polynomial in the numerator is 2.

the degree of the polynomial in the denominator is 2.

when the top and bottom have the same degree, like in this case, the horizontal asymptotes that that can afford us is simply the value of their coefficients.

[tex]\bf \cfrac{x^2-16}{x^2+2x+1}\implies \cfrac{1x^2-16}{1x^2+2x+1}\implies \stackrel{\textit{horizontal asymptote}}{y=\cfrac{1}{1}\implies y=1}[/tex]

for the second one

well, the degree of the numerator is 3.

the degree of the denominator is 2.

when the numerator has a higher degree than the denominator, there are no horizontal asymptotes, however, when the degree of the numerator is exactly 1 degree higher than that of the denominator, the rational has an oblique or slant asymptote, and its equation comes from the quotient of the whole expression, check the picture below, the top part.

for the third one

this one is about the same as the one before it, the numerator has exactly one degree higher than the denominator, so we're looking at an oblique asymptote, check the picture below, the bottom part.

Answer:

Step-by-step explanation:

Let the other leg = x

x^2 + 4^2 = (3x)^2

x^2 + 4^2 = 9x^2

4^2 = 9x^2 - x^2

16= 8x^2

16/8 = x^2

x^2 = 2

x = sqrt(2)

The lengths of the sides

x = sqrt(2)      

other side =4

hypotenuse = 3*sqrt(2)

x = 1.4

other side= 4

hypotenuse = 3*1.4142

hypotenuse = 4.2

Answer:

4 feet, 1.4 feet, 4.2 feet

Step-by-step explanation:

We are looking for the lengths of the three sides of a right triangle. We are given that one leg has length 4ft. Let x be the length of the other leg. Since the hypotenuse of the right triangle is three times the length of this leg, we can represent the hypotenuse as 3x. This is a right triangle, so we can use the Pythagorean Theorem to find x.

42+x216+x2=(3x)2=9x2

Subtracting x2 from both sides, then dividing by 8 to isolate the x, we have

8x2x2x=16=2=±2–√

Considering only the positive value for x, the lengths of the three sides of the triangle are approximately 4 feet, 2–√≈1.4 feet, and 32–√≈4.2 feet.

Answer:

  Your work is correct as far as it goes. Now eliminate the terms that are zero.

Step-by-step explanation:

Multiplying anything by zero gives zero. Adding zero is like adding nothing. Zero is called the "additive identity element" because ...

  a + 0 = a

Adding zero doesn't change anything. You can (and should) drop the zero if your goal is to simplify the expression.

[tex]a. \quad x_{f}=v_{0}\\\\b. \quad x_{f}=v_{0}t\\\\c. \quad v_{f}^2=v_{0}^2[/tex]

Answer:

Step-by-step explanation:

For the equation ...

  y = a(x -h)² +k

you can find the x-intercepts by setting y=0 and solving for x.

  0 = a(x -h)² +k

  -k = a(x -h)² . . . . . . subtract k

  -k/a = (x -h)² . . . . . divide by a

  ±√(-k/a) = x -h . . . . take the square root

  h ± √(-k/a) = x . . . . add h . . . . this is the general solution

__

So, for each of your problems, fill in the corresponding numbers and do the arithmetic. If (-k/a) is a negative number, the square root gives imaginary values, so there is "no solution".

1.  x = 5 ± √9 = {5 -3, 5 +3} = {2, 8} . . . . the x-intercepts are 2 and 8

2.  x = -3 ± √(-2) . . . . . . no solution; the roots are complex

3.  x = 5 ± √(-8/4) . . . . . no solution; the roots are complex

Answer:

Step-by-step explanation:

These are all done the exact same way.  I'll do the first one in its entirety, and you can do the rest, following my example.

Finding x-intercepts means that you find the places in the polynomial where the graph of the function goes through the x-axis.  Here, the y-coordinates will be 0.  To find these x-intercepts, you have to set y equal to 0 and then factor.  First, though, we need to know exactly what the polynomial looks like in standard form.  The ones you have are all in vertex form.  We find the standard form by first expanding the binomial, like this:

[tex]0=(x-5)(x-5)-9[/tex]

FOIL those out to get

[tex]x^2-10x+25-9=0[/tex]

Combine like terms to get

[tex]0=x^2-10x+16[/tex]

Now we have to factor that.  I'll use regular old factoring, although the quadratic formula will work also.

In our quadratic, a = 1, b = -10 and c = 16

The product of a * c = 16.  The factors of 16 are:

1, 16

2, 8

4, 4

Some combination of those factors will give us a -10, the b term.  2 and 8 will work, as long as they are both negative.  -2 + -8 = -10.  Fit them into the polynomial with the absolute value of the largest number named first:

[tex]x^2-8x-2x+16=0[/tex]

Now we group them by 2's without ever changing their order:

[tex](x^2-8)-(2x+16)=0[/tex]

and then factor out the common thing in each set of parenthesis.  The common thing in the first set of parenthesis is an x; the common thing in the second set is a 2:

[tex]x(x-8)-2(x-8)=0[/tex]

Now the common thing is (x - 8), so we factor that out and group together in a separate set of parenthesis what's left over:

[tex](x-8)(x-2)=0[/tex]

By the Zero Product Property, either x - 8 = 0 or x - 2 = 0.  Solving the first one for x:

x - 8 = 0 so x = 8

Solving the second one for x:

x - 2 = 0 so x = 2

The 2 solutions are x = 2 and x = 8, choices a and d.

Answer: Adjacent Angles

A pair of angles which share a common side and vertex is called adjacent angles.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

A pair of angles which share a common side and vertex.

If two angles share a side and a vertex, they are said to be adjacent in geometry.

In other words, adjacent angles do not overlap and are placed precisely next to one another.

Therefore, the right definition is adjacent angles.

Answer:

D

Step-by-step explanation:

Answer:

Option D (As the x-values go to negative infinity, the function's values go to positive infinity).

Step-by-step explanation:

The graphed function shows a curve which has two turning points and three x-intercepts, which means it is a cubic polynomial. To check which statement is true, we will check all the statements one by one.

Option A) The graph shows that after the second turning point, the function starts to increase. Which means that as x-values increase, the function values will approach positive infinity. Therefore, option A is incorrect.

Option B) This option is incorrect because the graph explicitly shows that f(0) = 0, which means that when x = 0, the function value is also 0.

Option C) This option is incorrect because the function value is 0 at the x-value = 0, as shown in the graph. It can be also seen that As the x-values go to negative infinity, the function's values go to positive infinity since the value of the function decreases as the value of x decreases. Hence Option D is the correct answer!!!

Answer:

The correct option is D.

Step-by-step explanation:

Consider the provided graph of the function.

As the x values go to positive infinity or negative infinity the function value increase or goes to positive infinity.

The end behavior of the function is,

[tex]f(x)\rightarrow +\infty, as x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow +\infty, as x\rightarrow +\infty[/tex]

Now consider the provided options.

Option A is incorrect because As the x-values go to positive infinity, the function's values go to positive infinity.

Option B is incorrect because As the x-values go to zero, the function's values doesn't go to positive infinity.

Option C is incorrect because As the x-values go to negative infinity, the function's values are not equal to zero.

Option D is the correct option because As the x-values go to negative infinity, the function's values go to positive infinity.

Therefore, the correct option is D.

Answer:

(a) The expression for the average cost per pair of shoes is [tex]A(x)=\frac{12000}{x}+19[/tex] and equation for the situation is [tex]\frac{12000}{x}+19-(\frac{12000}{x+1000}+19)=0.43[/tex].

(b) x=[tex]x\approx 4806[/tex]

(c) The average function is not defined for x=0, so the domain of the function is all real numbers except 0.

(d) The reasonable domain is all natural numbers.

Step-by-step explanation:

The cost in dollars to manufacture x pairs of shoes is given by

[tex]C(x)=12000+19x[/tex]

where, x is the pairs of shoes.

(a)

The expression for the average cost per pair of shoes.

[tex]A(x)=\frac{C(x)}{x}[/tex]

[tex]A(x)=\frac{12000+19x}{x}[/tex]

[tex]A(x)=\frac{12000}{x}+19[/tex]

This month, the manufacturer produced 1000 more pairs of shoes than last month. The average cost per pair dropped by $0.43.

[tex]A(x)-A(x+1000)=0.43[/tex]

[tex]\frac{12000}{x}+19-(\frac{12000}{x+1000}+19)=0.43[/tex]

Therefore the expression for the average cost per pair of shoes is [tex]A(x)=\frac{12000}{x}+19[/tex] and equation for the situation is [tex]\frac{12000}{x}+19-(\frac{12000}{x+1000}+19)=0.43[/tex].

(b)

On solving the above equation we get

[tex]\frac{12000}{x}-\frac{12000}{x+1000}=0.43[/tex]

[tex]\frac{12000000}{x^2 + 1000 x} = 0.43[/tex]

[tex]12000000=0.43(x^2 + 1000 x)[/tex]

[tex]12000000=0.43x^2 + 430x[/tex]

[tex]0=0.43x^2 + 430x-12000000[/tex]

Using graphing calculator we get

[tex]x\approx -5806.31,4806.31[/tex]

The pair of shoe can not be native and decimal value.

[tex]x\approx 4806[/tex]

Therefore the solution is [tex]x\approx 4806[/tex].

(c)

The average cost function is

[tex]A(x)=\frac{12000}{x}+19[/tex]

The function is not defined if the denominator is 0.

The above function is not defined for x=0, so the domain of the function is all real numbers except 0.

(d)

In the average function x represents the number of pair of shoe.

It means the value of x must be a positive integer.

Since the average function is not defined for x=0, So the reasonable domain of average function is

Domain={x : x∈Z⁺, x≠0}

Domain=N

Therefore the reasonable domain is all natural numbers.

The intersection of plane GFL and a plane that contains points A and C can be any plane that passes through those two points.

In mathematics, an intersection of two planes is the set of points that are common to both planes.

In this case, we want to find the intersection of plane GFL and a plane that contains points A and C.

Since both points A and C lie on the same plane, any plane that contains both points A and C would intersect plane GFL at those points.

Therefore, any plane that passes through points A and C would be an intersection of plane GFL and a plane that contains points A and C.

Answer:

  573.6 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship of right triangle sides and angles:

  Tan = Opposite/Adjacent

This tells us ...

  tan(61°) = (height)/(distance to first point)

or

  distance to first point = height/tan(61°)

Likewise, ...

  distance to second point = height/tan(32°)

Then the difference of the distances is ...

  distance to second point - distance to first point

     = height/tan(32°) -height/tan(61°)

  600 ft = height × (1/tan(32°) -1/tan(61°))

Dividing by the coefficient of height, we have ...

  height = (600 ft)/(1/tan(32°) -1/tan(61°)) ≈ (600 ft)/(1.04603) ≈ 573.6 ft

Answer:

y = 500(1.05)^x.

Step-by-step explanation:

551.25 = 500x^2    where x is the multiplier for each year.

x^2 = 551.25/500

x =  1.05

So the value after x years is 500(1.05)^x.

Answer: [tex]y=500(1.05)^x[/tex]

Step-by-step explanation:

The exponential growth equation is given by :-

[tex]y=A(1+r)^x[/tex]              (1)

, where A is the initial value of ,  r is the rate of growth ( in decimal) and t is the time period ( in years).

Given : The value of a collector’s item is expected to increase exponentially each year.

The item is purchased for $500. After 2 years, the item is worth $551.25.

Put A= 500 ;  t= 2 and y= 551.25 in (1), we get

[tex]551.25=500(1+r)^2\\\\\Rightarrow\ (1+r)^2=\dfrac{551.25}{500}\\\\\Rightarrow (1+r)^2=1.1025[/tex]    

Taking square root on both sides , we get

[tex]1+r=\sqrt{1.1025}=1.05\\\\\Rightarrow\ r=1.05-1=0.5[/tex]

Now, put A= 500 and r= 0.5 in (1), we get the equation represents y, the value of the item after x years as :

[tex]y=500(1+0.5)^x\\\\\Rightarrow\ y=500(1.05)^x[/tex]    

Answer:

ΔKLJ ~ ΔRPQ by AA~

Step-by-step explanation:

Angle angle similarity needs two corresponding angles in two triangles to be same. The two given triangles are similar by: ΔKLJ ~ ΔRPQ by AA~

It is a theorem in mathematics that sum of internal angles of a triangle equate to [tex]180^\circ[/tex]

Suppose that two angles are given as   [tex]a^\circ[/tex] and  [tex]b^\circ[/tex] and let there is one angle missing. Let its measure be [tex]x^\circ[/tex]

Then, by the aforesaid theorem, we get:

[tex]a^\circ + b^\circ + x^\circ = 180^\circ\\\\ \text{Subtracting a + b degrees from both sides} \\\\x^\circ = 180^\circ - (a^\circ + b^\circ)[/tex]

Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure. This makes all three angles same and thus, those two triangles are scaled copies of each other. Thus, they're called similar.

For given case, we've got

[tex]m\angle K = m\angle R\\m\angle J = m\angle Q\\[/tex]

Thus, for the rest of the angle pair, we have:

[tex]m\angle L = 180 - (m\angle J + m\angle K) = 180 - (m\angle Q + m\angle R) = m\angle P\\\\m\angle L = m\angle P[/tex]
