Answer:

The length of arc AC is [tex]15\pi\ cm[/tex]

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

[tex]C=\pi D[/tex]

we have

[tex]D=36\ cm[/tex]

substitute

[tex]C=\pi (36)[/tex]

[tex]C=36\pi\ cm[/tex]

step 2

Find the length of arc AC

Remember that the circumference subtends a central angle of 360 degrees

The measure of arc AC is equal to

arc AC+30°=180° ----> because the diameter divide the circle into two equal parts

arc AC=180°-30°=150°

using proportion

[tex]\frac{36\pi}{360}=\frac{x}{150}\\ \\x=36\pi*150/360\\ \\x=15\pi\ cm[/tex]

Answer:

D. {(7, 11), (0,5), (11, 7), (7,13)}

Step-by-step explanation:

Because the relations (7, 11), (7,13) are false.

f(7) = 11

f(7) = 13

=> 11 = 13 (F)

Answer:

The correct answer option is: D. {(7, 11), (0,5), (11, 7), (7,13)}.

Step-by-step explanation:

We are given some paired values of inputs and outputs (x and y) for a function and we are to determine whether which of them is not a function.

For a relation to be function, no value of x should be repeated. It means that for each value of y, there should be a unique value of x (input).

In option D, two of the pairs have same value of x. Therefore, it is not a function.

Answer:

  a) growth will reach a peak and begin declining after about 42.6 days. 5000 people will be infected at that point

  b) the infected an uninfected populations will be the same after about 42.6 days

Step-by-step explanation:

We have assumed you intend the function to match the form of a logistic function:

[tex]P(t)=\dfrac{Kpe^{rt}}{K+p(e^{rt}-1}[/tex]

This function is symmetrical about its point of inflection, when half the population is infected. That is, up to that point, it is concave upward, increasing at an increasing rate. After that point, it is concave downward, decreasing at a decreasing rate.

a) The growth rate starts to decline at the point of inflection, when half the population is infected. That time is about 42.6 days after the start of the infection. 5000 people will be infected at that point

b) The infected and uninfected populations will be equal about 42.6 days after the start of the infection.

Answer: 0.9887

Step-by-step explanation:

Given : The true probability of a baby being a boy : [tex]0.527[/tex]

The number of selected births : [tex]7[/tex]

Now, the when next seven randomly selected births in the​ country, then the probability that at least one of them is a girl​ is given by :_

[tex]\text{P(at least one girl)=1-P(none of them girl)}\\\\=1-(0.527)^7=0.988710510435\approx0.9887[/tex]

Hence, the probability that at least one of them is a girl​ =0.9887

Final answer:

The probability of at least one girl being born among seven births in a country where a boy has a 0.527 chance of being born is calculated by subtracting the probability of all seven being boys from 1.

Explanation:

The question asks about the probability of at least one girl being born among the next seven randomly selected births in a country where the true probability of a baby being a boy is 0.527. To find this, we can use the complement rule, which focuses on the probability that all seven births will be boys, the opposite of what we want to find.

First, we find the probability of all seven being boys:

P(all boys) = (0.527)⁷

Next, we subtract this from 1 to get the probability of at least one girl:

P(at least one girl) = 1 - P(all boys)

This gives us the probability that at least one of the next seven births will be a girl.

Step-by-step explanation:

All people who work do so in an office, at a computer. Bill works, so he works in an office, at a computer.

This is false generalization.

A false generalization is a mistake that we do when we generalize something without considering all the points or variables.

Like here, if people work, that does not generally means they always work in offices and work in front of computers.

There are many professions like various sports, civil engineering, police patrolling etc that cannot be done while sitting in an office and in front of a computer.

Answer:

8 is the number.

Step-by-step explanation:

We are given the following expression in words which we are to translate into mathematical expression and tell the number:

'eight times the sum of 5 and some number is 104'

Assuming the number to be [tex]x[/tex], we can write it as:

[tex] 8 ( 5 + x ) = 1 0 4 [/tex]

[tex] 5 + x = \frac { 1 0 4 } { 8 } [/tex]

[tex] 5 + x = 1 3 [/tex]

[tex]x=13-5[/tex]

x = 8

ANSWER

[tex]8[/tex]

EXPLANATION

Let the number be y.

Eight times the sum of the number and 5 is written as:

[tex]8(5 + y)[/tex]

From the question, this expression must give us 104.

This implies that:

[tex]8(5 + y) = 104[/tex]

Expand the parenthesis to get;

[tex]40 + 8y = 104[/tex]

Group similar terms to get:

[tex]8y = 104 - 40[/tex]

Simplify:

[tex]8y = 64[/tex]

[tex]y = \frac{64}{8} [/tex]

This finally evaluates to

[tex]y=8[/tex]

Hence the number is 8

For this case we have the following expression:

[tex](\frac {-27x ^ 0 * y ^ {- 2}} {54x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =[/tex]

By definition we have to:

[tex]a^0 = 1[/tex]

So:

[tex](\frac {-27y ^ {- 2}} {54x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =[/tex]

Simplifying:

[tex](\frac {-y ^ {- 2}} {2x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =[/tex]

By definition of power properties we have to:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

So, rewriting the expression we have:

[tex](-1)^{-2}\frac{-y^{-2*-2}}{2^{-2}*x^{-5*-2}*y^{-4*-2}}=\\\frac{1}{(-1)^2}*\frac{-y^{4}}{2^{-2}x^{10}*y^{8}}=[/tex]

SImplifying:

[tex]+1*\frac{y^{4-8}}{2^{-2}x^{10}}=\\\frac{y^{-4}}{2^{-2}x^{10}}=\\\frac{2^2}{x^{10}y^{4}}[/tex]

Answer:

[tex]\frac{4}{x^{10}y^{4}}[/tex]

Answer:

  (x, y, z) = (0, 0, 0) +t(1, 5, 4)

Step-by-step explanation:

Such a parametric equation can be written in the form ...

  (first point) + t×(change in point values)

where the change in point values is the difference between the point coordinates.

Since the first point is (0, 0, 0), the change is easy to find. It is exactly equal to the second point's coordinates. Hence our equation is ...

  (x, y, z) = (0, 0, 0) +t(1, 5, 4)

The sum can be "simplified" to ...

  (x, y, z) = (t, 5t, 4t)

Answer: 0.2

Step-by-step explanation:

Given: The commuting time on a particular train is uniformly distributed over the interval (42,52).

∴ The probability density function of X will be :-

[tex]f(x)=\dfrac{1}{b-a}\\\\=\dfrac{1}{52-42}=\dfrac{1}{10}, 42<x<52[/tex]

Thus, the required probability :-

[tex]P(X<44)=\int^{44}_{42}f(x)\ dx\\\\=\int^{44}_{42}\dfrac{1}{10}\ dx\\\\=\dfrac{1}{10}[x]^{44}_{42}=\dfrac{1}{10}(44-42)=\dfrac{1}{5}=0.2[/tex]

Hence, the  probability that the commuting time will be less than 44 ​minutes= 0.2

the probability that the commuting time will be less than 44 minutes is 0.2 or 20%.

To calculate the probability that the commuting time will be less than 44 minutes, given that it is uniformly distributed between 42 and 52 minutes, we use the formula for the probability of a continuous uniform distribution:

P(a < X < b) = (b - a) / (max - min)

Here, min is 42, max is 52, a is 42 (since that's the minimum time), and b is 44 (the time we are interested in). So the probability that the commuting time is less than 44 minutes will be:

P(42 < X < 44) = (44 - 42) / (52 - 42) = 2 / 10

This simplifies to 1/5 or 0.2.

Therefore, the probability that the commuting time will be less than 44 minutes is 0.2 or 20%.

Answer:

P (Math or English) = 0.90

Step-by-step explanation:

* Lets study the meaning of or , and on probability

- The use of the word or means that you are calculating the probability

  that either event A or event B happened

- Both events do not have to happen

- The use of the word and, means that both event A and B have to

  happened

* The addition rules are:

# P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen

  at the same time)

# P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they  

   have at least one outcome in common)

- The union is written as A ∪ B or “A or B”.  

- The Both is written as A ∩ B or “A and B”

* Lets solve the question

- The probability of taking Math class 71%

- The probability of taking English class 77%

- The probability of taking both classes is 58%

∵ P(Math) = 71% = 0.71

∵ P(English) = 77% = 0.77

∵ P(Math and English) = 58% = 0.58

- To find P(Math or English) use the rule of non-mutually exclusive

∵ P(A or B) = P(A) + P(B) - P(A and B)

∴ P(Math or English) = P(Math) + P(English) - P(Math and English)

- Lets substitute the values of P(Math) , P(English) , P(Math and English)

 in the rule

∵ P(Math or English) = 0.71 + 0.77 - 0.58 ⇒ simplify

∴ P(Math or English) =  0.90

* P(Math or English) = 0.90

To find the probability that a randomly selected student is taking a math class or an English class, use the principle of inclusion-exclusion. The probability is 90%.

To find the probability that a randomly selected student is taking a math class or an English class, we can use the principle of inclusion-exclusion. We know that 71% of students are taking a math class, 77% are taking an English class, and 58% are taking both.

To find the probability of taking either math or English, we add the probabilities of taking math and English, and then subtract the probability of taking both:

P(Math or English) = P(Math) + P(English) - P(Math and English)

= 71% + 77% - 58%

= 90%

Therefore, the probability that a randomly selected student is taking a math class or an English class is 90%.

The given altitude of triangle ABC is h, is located inside the triangle and

extends from side AB to the vertex C.

The true statements are;

I. Triangle ABC could be a right triangle

II. Angle C cannot be a right angle

Reasons:

I. Triangle ABC could be a right triangle

The altitude drawn from the vertex C to the line AB = h

The length of h = AB

Where, triangle ABC is a right triangle, we have;

The legs of the right triangle are; h and AB

The triangle ABC formed is an isosceles right triangle

Therefore, triangle ABC could be an isosceles right triangle; True

II. Angle C cannot be a right angle: True

If angle ∠C is a right angle, we have;

AB = The hypotenuse (longest side) of ΔABC

Line h = AB is an altitude, therefore, one of the sides of ΔABC is hypotenuse to h, and therefore, longer than h and AB, which is false

Therefore, ∠C cannot be a right angle

III. Angle C could be less than 45 degrees; False

The minimum value of angle C is given by when triangle ABC is an isosceles right triangle. As the position of h shifts between AB, the lengths of one of the sides of ΔABC increases, and therefore, ∠C, increases

Therefore, ∠C cannot be less than 45°

Answer: 61,750 miles

Step-by-step explanation:

Given : The p-value of the tires to outlast the warranty = 0.96

The probability that corresponds to 0.96 from a Normal distribution table is 1.75.

Mean : [tex]\mu=60,000\text{ miles}[/tex]

Standard deviation : [tex]\sigma=1000\text{ miles}[/tex]

The formula for z-score is given by  : -

[tex]z=\dfrac{x-\mu}{\sigma}\\\\\Rightarrow\ 1.75=\dfrac{x-60000}{1000}\\\\\Rightarrow\ x-60000=1750\\\\\Rightarrow\ x=61750[/tex]

Hence, the tread life of tire should be 61,750 miles if they want 96% of the tires to outlast the warranty.

The company looking to ensure 96% of the tires outlast the warranty should use a mileage warranty of 58,250. This ensures a failure rate of only 4%, as calculated using statistics and the concept of normal distribution.

The question deals with the concept of normal distribution in statistics, specifically, with an application to a real-life situation - to decide the warranty for a product (in this case, a type of tire). The mean and standard deviation given represent the average life and variation in life of the tires respectively. If the company wants 96% of the tires to outlast the warranty, then they are looking to find the lifespan beyond which only 4% of the tires would fail.

The Z-score corresponding to the 96th percentile in a standard normal distribution table is roughly 1.75. Since standard deviation is 1,000 miles, that implies that 1.75 standard deviations below the average is acceptable for the warranty. Therefore, we calculate the warranty as Mean - 1.75*Standard Deviation, which results in 60,000 - 1.75*1000 = 58,250 miles. Thus, the company should use a warranty of 58,250 miles.

[tex]x^2(v''x^3+6v'x^2+6vx)-x(v'x^3+3vx^2)-3vx^3=0[/tex]

[tex]x^5v''+5x^4v'=0[/tex]

Let [tex]u(x)=v'(x)[/tex], so that

[tex]\begin{cases}u=v'\\u'=v''\end{cases}[/tex]

Then the ODE becomes

[tex]x^5u'+5x^4u=0[/tex]

and we can condense the left hand side as a derivative of a product,

[tex]\dfrac{\mathrm d}{\mathrm dx}[x^5u]=0[/tex]

Integrate both sides with respect to [tex]x[/tex]:

[tex]\displaystyle\int\frac{\mathrm d}{\mathrm dx}[x^5u]\,\mathrm dx=C[/tex]

[tex]x^5u=C\implies u=Cx^{-5}[/tex]

Solve for [tex]v[/tex]:

[tex]v'=Cx^{-5}\implies v=-\dfrac{C_1}4x^{-4}+C_2[/tex]

Solve for [tex]y_2[/tex]:

[tex]\dfrac{y_2}{x^3}=-\dfrac{C_1}4x^{-4}+C_2\implies y_2=C_2x^3-\dfrac{C_1}{4x}[/tex]

So another linearly independent solution is [tex]y_2=\dfrac1x[/tex].

The probability that a randomly selected dropout aged 16 to 17 is white, given the provided statistics, is 67.39%.

The student is asking a question related to conditional probability in the field of Mathematics. The question prompts us to find out the probability that a randomly selected high school dropout in the age range of 16 to 17 is white. To find the answer, we use the following formula:

P(A|B) = P(A ∩ B) / P(B)

Where:
P(A|B) is the probability of event A happening given that event B has occurred.
P(A ∩ B) is the probability of both event A and event B happening together.
P(B) is the probability of event B happening.

From the problem statement, we know that P(B), the percentage of dropouts who are 16-17 years old, is 9.2%. Also, P(A ∩ B), the percent of dropouts who are both white and 16-17 years old, is given as 6.2%. We are supposed to find P(A|B), the probability that a dropout is white given that they are 16-17 years old.

Therefore, by substituting these values into the formula, we get:

P(A|B) = 6.2% / 9.2% = 67.39%

Rounded to two decimal places, the answer is 67.39%. So, there is approximately a 67.39% chance that a random high school dropout aged 16-17 is white.
