(b) find the probability that the next text arrives between 9:07 and 9:10 p.m. (c) find the probability that a text arrives before 9:03 p.m. (d) a text has not arrived for 5 minutes. find the probability that none will arrive for 7 minutes.

Answers

Answer 1

So the probability that Joe will not receive a text in the next 10 minutes is approximately 0.865. So the probability that the next text arrives between 9:07 and 9:10 p.m. is approximately 0.149. So the probability that a text arrives before 9:03 p.m. is approximately 0.393. So the probability that no text will arrive for 7 minutes, given that no text has arrived for 5 minutes, is approximately 0.394.

(a) To find the probability that Joe will not receive a text in the next 10 minutes, we can use the cumulative distribution function (CDF) of the exponential distribution. The CDF gives the probability that the time until the next text is less than or equal to a given time t. The CDF of an exponential distribution with mean 5 minutes is:

\(F(t) = 1 - e^{(-t/5)}\)

To find the probability that Joe will not receive a text in the next 10 minutes, we need to find F(10):

\(F(10) = 1 - e^{(-10/5)}\)

\(= 1 - e^{(-2)}\)

≈ 0.865

(b) To find the probability that the next text arrives between 9:07 and 9:10 p.m., we need to find the probability that the time until the next text is between 7 and 10 minutes. We can use the CDF again to find this probability:

P(7 < X < 10) = F(10) - F(7)

\(= (1 - e^{(-10/5)}) - (1 - e^{(-7/5)})\)

\(= e^{(-7/5)} - e^{(-2)}\)

≈ 0.149

(c) To find the probability that a text arrives before 9:03 p.m., we need to find the probability that the time until the next text is less than 3 minutes. We can use the CDF again to find this probability:

P(X < 3) = F(3)

\(= 1 - e^{(-3/5)}\)

≈ 0.393

(d) To find the probability that no text will arrive for 7 minutes, given that no text has arrived for 5 minutes, we can use the memoryless property of the exponential distribution. The memoryless property states that the conditional distribution of the time until the next text, given that no text has arrived in the first 5 minutes, is the same as the original distribution. In other words, the fact that no text has arrived in the first 5 minutes does not affect the probability of a text arriving in the next 7 minutes.

Therefore, the probability that no text will arrive for 7 minutes, given that no text has arrived for 5 minutes, is the same as the probability that no text will arrive for 7 minutes starting from scratch. This is the probability that the time until the next text is greater than 7 minutes. Using the CDF of the exponential distribution, we can calculate:

P(X > 7) = 1 - F(7)

\(= 1 - (1 - e^{(-7/5)})\)

= \(e^{(-7/5)}\)

≈ 0.394

Find the vectors t, n, and b at the given point. r(t) = 3 cos t, 3 sin t, 3 ln cos t , (3, 0, 0)

Answers

Here are the vectors **t**, **n**, and **b** at the given point:

* **t** = (-3 sin t, 3 cos t, 0)

* **n** = (-3 cos t, -3 sin t, 3 / cos^2 t)

* **b** = (3 cos^2 t, -3 sin^2 t, -3)

The vector **t** is the unit tangent vector, which points in the direction of the curve at the given point. The vector **n** is the unit normal vector, which points in the direction perpendicular to the curve at the given point. The vector **b** is the binormal vector, which points in the direction that is perpendicular to both **t** and **n**.

To find the vectors **t**, **n**, and **b**, we can use the following formulas:

```

t(t) = r'(t) / |r'(t)|

n(t) = (t(t) x r(t)) / |t(t) x r(t)|

b(t) = t(t) x n(t)

```

In this case, we have:

```

r(t) = (3 cos t, 3 sin t, 3 ln cos t)

r'(t) = (-3 sin t, 3 cos t, 3 / cos^2 t)

```

Substituting these into the formulas above, we can find the vectors **t**, **n**, and **b** as shown.

The vectors **t**, **n**, and **b** are all orthogonal to each other at the given point. This is because the curve is a smooth curve, and the vectors are defined in such a way that they are always orthogonal to each other.

The binormal vector (b) is perpendicular to both the tangent and normal vectors and completes the orthogonal coordinate system.

To find the vectors t, n, and b at the given point, we need to calculate the first derivative, second derivative, and third derivative of the position vector r(t).
Given r(t) = (3 cos t, 3 sin t, 3 ln cos t), we can calculate the derivatives as follows:
First derivative:
r'(t) = (-3 sin t, 3 cos t, -3 sin t / cos t)
Second derivative:
r''(t) = (-3 cos t, -3 sin t, -3 cos t / cos^2 t + 3 sin^2 t / cos t)
       = (-3 cos t, -3 sin t, -3 cos t / cos^2 t + 3 tan^2 t)
Third derivative:
r'''(t) = (3 sin t, -3 cos t, 6 cos t / cos^3 t - 6 sin t / cos t)
        = (3 sin t, -3 cos t, 6 sec^3 t - 6 tan t sec t)
At the given point (3, 0, 0), substitute t = 0 into the derivatives to find the vectors:
r'(0) = (0, 3, 0)
r''(0) = (-3, 0, 3)
r'''(0) = (0, -3, 6)
Therefore, at the given point, the vectors t, n, and b are:
t = r'(0) = (0, 3, 0)
n = r''(0) = (-3, 0, 3)
b = r'''(0) = (0, -3, 6)
These vectors represent the tangent, normal, and binormal vectors, respectively, at the given point.
The tangent vector (t) represents the direction of motion of the curve at that point. The normal vector (n) is perpendicular to the tangent vector and points towards the center of curvature.

The binormal vector (b) is perpendicular to both the tangent and normal vectors and completes the orthogonal coordinate system.

Determine the intervals on which the function is decreasing and increasing and then find local minima and maxima. f(x) = (x-2)(x+3) f(x) = (x+1)(x-2)(x+3) f(x) = x e^(-x) f(x) = x^x defined on the interval (0, infinity).

Answers

The intervals on which the function is decreasing and increasing and the local minima and maxima are

a. f(x) = (x-2)(x+3),  increasing on the interval (-∞, -1/2) and (1/2, ∞) and decreasing on the interval (-1/2, 1/2). f(x) has a local minimum at x = -1/2 and a local maximum at x = 1/2.

b.  f(x) = (x+1)(x-2)(x+3),increasing on the interval (-∞, -1) and (2, ∞) and decreasing on the interval (-1, 2). f(x) has a local maximum at  x = -1 and a local minimum at x = 2

c. f(x) = x e⁻ˣ, increasing on the interval (1, ∞) and decreasing on the interval (0, 1). f(x) has a local minimum at  x = 1 and doesn't have local maximum or infinite

d.  f(x) = xˣ, decreasing on the interval (0, 1/e) and increasing on the interval (1/e, ∞). f(x) has a local maximum at x = 1/e. Note that there is no local minimum for this function.

a) f(x) = (x-2)(x+3)

To determine where the function is increasing or decreasing, we can take the derivative of f(x):

f'(x) = 2x + 1

This derivative is positive for x > -1/2, which means that f(x) is increasing on the interval (-∞, -1/2) and (1/2, ∞). The derivative is negative for x < -1/2, which means that f(x) is decreasing on the interval (-1/2, 1/2). The critical points occur at x = -1/2 and x = 1/2. f(x) has a local minimum at x = -1/2 and a local maximum at x = 1/2.

b) f(x) = (x+1)(x-2)(x+3)

To determine where the function is increasing or decreasing, we can take the derivative of f(x):

f'(x) = 3x² - 6x - 3

This derivative can be factored as f'(x) = 3(x+1)(x-2). The derivative is positive for x > 2 and negative for x < -1, which means that f(x) is increasing on the intervals (-∞, -1) and (2, ∞), and decreasing on the interval (-1, 2). The critical points occur at x = -1 and x = 2. f(x) has a local maximum at x = -1 and a local minimum at x = 2.

c) f(x) = x e⁻ˣ

To determine where the function is increasing or decreasing, we can take the derivative of f(x):

f'(x) = e⁻ˣ - xe⁻ˣ

Setting this derivative equal to zero and solving for x, we get x = 1. Therefore, the function has a critical point at x = 1. We can evaluate the derivative for values of x less than and greater than 1 to determine the intervals on which f(x) is increasing and decreasing.

f'(x) is negative for x < 1 and positive for x > 1, which means that f(x) is decreasing on the interval (0, 1) and increasing on the interval (1, ∞). f(x) has a local minimum at x = 1.

d) f(x) = xˣ

To determine where the function is increasing or decreasing, we can take the derivative of f(x):

f'(x) = xˣ (ln(x) + 1)

Setting this derivative equal to zero and solving for x, we get x = 1/e.

Therefore, the function has a critical point at x = 1/e. We can evaluate the derivative for values of x less than and greater than 1/e to determine the intervals on which f(x) is increasing and decreasing. f'(x) is negative for 0 < x < 1/e and positive for x > 1/e, which means that f(x) is decreasing on the interval (0, 1/e) and increasing on the interval (1/e, ∞).

f(x) has a local maximum at x = 1/e. Note that there is no local minimum for this function.

UR = 19 ft

What is perimeter of a shape?

Perimeter of a shape is the length of the boundary of the shape.

It is obtained by taking the sum of all the length of the boundary.

Here,

UT = (25 - x) ft

ST = (3x + 1) ft

RS = (13 + x) ft

UR = (4x - 5) ft

Perimeter = UT + ST + RS + UR

                = (25 - x + 3x + 1  + 13 + x +4x -5) ft

By the problem,

\(7x +34 =76\\7x = 76 -34\\7x = 42\\x = \frac{42}{7}\\x =6\)

UT = \(25 - 6\) = \(19\) ft

A drawer is filled with 2 black shirts, 7 white shirts, and 11 gray shirts. One shirt is chosen at random from the drawer. Find the probability that it is not a black shirt.

Answers

Answer: Probability = 90%

Step-by-step explanation:

In a drawer we have:

2 black shirts

7 white shirts

11 gray shirts

If we would randomly pick a shirt, what are the chances of it not being black?

To do that, we first need to calculate the probability of getting a black shirt.

To calculate that, we need to divide the number of black shirts by the total number of shirts.

Black shirts = 2

Total shirts = 2 + 7 + 11 = 20

That will be 2 black shirts divided by 20.

We get 0.1

If we multiply 0.1 by 100%, we get a 10% chance to get a black shirt.

Now, to know to chances of not getting a black shirt, we just need to subtract 10% from 100%.

And that will be 90% chances of not getting a black shirt.

Probability = 90%

                      y - y1 = m(x - x1)

The given equation is \(y=-\frac{3}{4}x-17\)

The required line is parallel to the given line.

Can someone help me with this Question.

Answers

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

\(P=3W+D\)

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

A 8 wins, 5 draws

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

B 54 points

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

= 60

The positive integers that can divide a number evenly are referred to as factors. Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied.

Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.

how many solutions does 12x + 1 = 12x - 10

Answers

Answer:

No solutions

Step-by-step explanation:

First things first we need to get rid of the variables so we subtract -12x from one side to the other.

Now we have 1= -10

In this case, 1 is not equal to -10 so we get no solutions!

(Side note: if they were the same like 3=3 that would be all solutions.)

how many significant figures are there in the number 1.032

Answers

There are four significant figures in the number 1.032.

Significant figures are the digits in a number that carry meaningful information about its precision. To determine the significant figures in a number, follow these rules:

Non-zero digits are always significant. In this case, the digits 1, 0, 3, and 2 are non-zero.

Zeroes between non-zero digits are significant. In this case, the zero between 1 and 3 is significant.

Leading zeroes (zeros before the first non-zero digit) are not significant. In this case, there are no leading zeroes.

Trailing zeroes (zeros after the last non-zero digit) are significant only if there is a decimal point present. In this case, there is a trailing zero after the 2, and since there is a decimal point, it is significant.

By applying these rules, we find that the number 1.032 has four significant figures.

The number 1.032 has four significant figures.

Determine whether the point (0,0) is in the solution set of each inequality.

Determine whether the point (0,0) is in the solution set of each inequality.

Answers

a) No

b) Yes

1) Let's check algebraically whether (0,0) is the solution set

-2x +3y > 9 Plug into x and y the values of 0,0

-2(0) +3(0) > 9

0 > 9 FALSE! Since 0 can't be greater than 9

1.5x - y ≥ -4 Plug into x and y the values of 0,0

1.5(0) -0 ≥ -4

0 ≥ -4 True

2) Hence, point (0,0) verifies only the second equation.

Why was the volume of your fountain smaller than the volume of the ideal sphere? Discuss a more accurate method for approximating the volume of the

spherical slab other than using just cylindrical slabs. Discuss in two to three sentences.

Answers

Yes, the volume of the fountain smaller than the volume of the ideal sphere.

What is the shape of the fountain and sphere?

The fountain shapes contain the cylindrical slabs, and a sphere is a three-dimensional, spherical solid figure in geometry.

Since the cylindrical slabs used for approximation do not exactly suit the sphere's curvature, gaps exist between the slabs and the sphere's surface, causing the volume of the fountain to be less than the volume of the ideal sphere.

Hence, the volume of the fountain smaller than the volume of the ideal sphere.
