Find the value of x that makes f^-1 g ^-1 (x) = 0.
Give your answer as an integer or as a decimal.

Answers

Using the inverse function method, the value of x should be x = 7/2 or x = -5

From the case, we know that:

f(x) = (6x + 7) / 2

g(x) = 3x - 5

f⁻¹.g⁻¹(x) ?

First, we need to find the inverse function of each given functions. We assume that:

f⁻¹(x) = p

g⁻¹(x) = q

f⁻¹(x) = (6x + 7) / 2

p = (6x + 7) / 2

2p = 6x + 7

2p - 7 = 6x

x = (2p - 7) / 6

f⁻¹(x) = (2x - 7) / 6

g⁻¹(x) = 3x - 5

q = 3x - 5

q + 5 = 3x

x = (q + 5) / 3

g⁻¹(x) = (x + 5) / 3

Next, we will try to find the value of x

f⁻¹.g⁻¹(x) = 0

(2x - 7) . (x + 5) = 0

A window has the shape of a rectangle surmounted by an equilateral triangle. If the perimeter of the window is 12m, find the dimensions of the rectangle that will produce the largest area of the window.

Answers

The dimensions of the rectangle that will produce the largest area of the window are x = (12 - √3) / 2 and y = 3 / √3.

Let x be the length of the rectangle, and y be the width of the rectangle. The perimeter of the window is 12m, and since the triangle is equilateral, we know that all 3 sides of the triangle are equal to x.

Therefore, we can set up the following equation to represent the perimeter of the window: x + y + x = 12

The area expression is:

A = x*y + (x^2 * √3)/4

After substituting x = (12-y)/2, the area expression becomes:

A = [((12-y)/2)*y] + [(12-y)^2 * √3]/16

Which can be simplified to:

A = 6y - 3y^2 + (9-3y)√3 / 4

To find the maximum value of this expression, we can differentiate it with respect to y and set it to zero:

dA/dy = -3y + (9-3y)√3/4 = 0

and solve for y:

-3y + (9-3y)√3/4 = 0

-3y = (3y-9)√3/4

-3y = 3y-9 / 2√3

3y = 9 / 2√3

y = 3 / √3

To find x, we can substitute this value of y back into x = (12-y)/2:

x = (12 - 3 / √3) / 2 = (12 - √3) / 2

So the dimensions of the rectangle that will produce the largest area of the window are x = (12 - √3) / 2 and y = 3 / √3.

(note: z represents a standard normal random variable.)

Answers

The probability that at least 27 percent of the children in the sample live in households that are classified at the particular income level is approximately 0.04.

What is the binomial distribution?

In a binomial distribution, the probability of getting success must remain the same for the trials we are investigating. For example, when tossing a coin, the probability of flipping a coin is ½ or 0.5 for every trial we conduct, since there are only two possible outcomes.

To approximate the probability that at least 27 percent of the children in the sample live in households that are classified at the particular income level, we can use a normal approximation to the binomial distribution.

The sample size is n = 300 and the proportion in the population is p = 0.22. The standard deviation of the sample proportion is:

[tex]\sigma_{p}[/tex] = √(p(1-p)/n) = √(0.22(1-0.22)/300) = 0.0115

We can use the standard normal distribution to approximate the probability that the sample proportion is at least 0.27:

[tex]P(p_{hat} > = 0.27) \approx P( (p_{hat} - p) / \sigma_{p} > = (0.27 - 0.22) / 0.0115 )[/tex]

P(z >= 1.74)

where z is the standard normal variable.

We can use a standard normal table or calculator to find the probability for z >= 1.74 is about 0.04.

Hence, the probability that at least 27 percent of the children in the sample live in households that are classified at the particular income level is approximately 0.04.

Solve the system of liner equations using elimination by multiplication

Answers

Answer:

H = 3

K = 0

Step-by-step explanation:

To solve the system of linear equations using elimination by multiplication, we can first multiply the first equation by 3. This gives us:

3(H+2k)=3*3=9

3H+6k=9

Now we have the same coefficient (6k) on the second variable in both equations. We can now subtract the first equation from the second equation to eliminate the second variable:

3H+6k=9

-3H-6k=-9

0H=0

This tells us that the system of equations is consistent and has infinitely many solutions. To find the specific solution, we can use either equation and substitute in a value for one of the variables. For example, we can use the first equation and substitute in H=3. This gives:

3+2k=3

2k=0

k=0

Now we can substitute this value for k back into either equation to find the value of H. For example, using the first equation:

H + 2(0) = 3

H = 3

So the solution to the system of equations is:

H = 3, k = 0

Write the equation of the line that passes through the points (-3, 3) and (1, 2).

Answers

The equation of a line passing through the points (-3, 3) and (1, 2) is x + 4y = 9

What is line passing through the points?

When two points in a plane are given, a line passing through them can be determined. It is the set of all points in the plane that are equidistant from the two given points.

These points form a straight line, which can be represented by an equation with two variables.

The equation of the line can be found using the slope-intercept form or by solving a system of two equations.

The slope of the line is the ratio of the change in the y-coordinate of the two points over the change in the x-coordinate of the two points.

The y-intercept is the point where the line crosses the y-axis. The line can also be expressed in terms of its intercepts on the x and y-axes.

The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

We know that the equation of a line passing through the points (x1, y1) and (x2 , y2) is given by y - y1 = m (x - x1).

m is the slope given by the formula m = (y2 - y1) / (x2 - x1)

Hence on substituting the given points in the equation of a line, we get

y - 3 = m ( x - (-3) ) -------(1)

m =  (y2 - y1) / (x2 - x1)

m = (2 - 3) / (1+3)

m = -1/4

Substituting value of m in equation (1), we get

y - 3 = -1/4 ( x + 3)

4(y - 3) = -x - 3

4y - 12 = -x - 3

x + 4y = -3 +12

x + 4y = 9

Therefore, the equation of a line passing through the points (-3, 3) and (1, 2) is x + 4y = 9

In baseball, a ".300 hitter" gets a hit 30% of the time. (For those of you not well-versed in spiritual things like baseball: hitting .300 is pretty good.) Suppose a player has five times at bat in a game.

a) What is the probability of getting at least one hit in a game?

b) What is the probability of getting at least one hit, in ten consecutive games?


The answers are 0.8319, 0.1588, but I don`t understand how the textbook got them.

Answers

Step-by-step explanation:

a) The probability of getting at least one hit in a game can be found by using the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening.

In this case, the event of getting at least one hit in a game is the complement of getting no hits in a game.

To get no hits in a game, the player must get 0 hits out of 5 at bats.

The probability of getting no hits in a game is (1-.3)^5 = 0.168.

Therefore, the probability of getting at least one hit in a game is 1 - 0.168 = 0.832

b) The probability of getting at least one hit in ten consecutive games is found by multiplying the probability of getting at least one hit in one game by itself ten times.

So it would be (0.832)^10 = 0.1588

Alternatively, we could use the binomial distribution formula, where probability of getting a hit k times out of n trials is given by

P(k) = (n choose k) * p^k * (1-p)^(n-k)

If we want to find the probability of getting at least one hit in ten games, we need to find the probability of getting 0 hits in all ten games and subtract it from 1.

1 - (1 - 0.832)^10 = 0.1588

So the probability of getting at least one hit in ten consecutive games is 0.1588.

Step-by-step explanation:

To set the fractions to a common denominator, we need to know what number they both share. In this case, both 7 and 10 share the number 70, since 7 * 10 is 70.

Therefore, we can multiply 2/7 by 10/10 and 3/10 by 7/7:

[tex]\frac{2}{7}[/tex] * [tex]\frac{10}{10}[/tex] = [tex]\frac{20}{70}[/tex]

[tex]\frac{3}{10}[/tex] * [tex]\frac{7}{7}[/tex] = [tex]\frac{21}{70}[/tex]

Answer: Common denominator = 70

Step-by-step explanation: In order to find a common denominator, we need to find what number they have in common. That'd be 70. So, now rewrite the fractions like this:

[tex]\frac{2}{7} = \frac{?}{70}[/tex]

[tex]\frac{3}{10} = \frac{?}{70}[/tex]

Now, we need to find the equivalent fractions on the right. To do that, use this formula for part 1:

Right denominator / left denominator

Then, what you get after dividing those 2, you multiply by the left numerator.

So, let's plug the numbers in:

70 / 7 = 10

10 * 2 = 20

Therefore, [tex]\frac{2}{7} = \frac{20}{70}[/tex]

70 / 10 = 7

3 * 7 = 21

Therefore, [tex]\frac{3}{10} = \frac{21}{70}[/tex]

jason had $32. he spent all the money buying four cds for x dollars each and two magazines for y dollars each. if jason had bought five cds and two magazines, he would have run short by $4. the following system of equations models this scenario: 4x 2y

Answers

Step-by-step explanation:

The given system of equations models the scenario where Jason spent all of his money on buying CDs and magazines, and that if he had bought one more CD, he would have run out of money. The system of equations is:

4x + 2y = 32 (Equation 1)

5x + 2y = 36 (Equation 2)

The first equation represents the total amount of money Jason spent on 4 CDs (x dollars each) and 2 magazines (y dollars each). The second equation represents the total amount of money Jason would have spent if he had bought one more CD. By subtracting equation 1 from equation 2, we get:

x = 4 (Equation 3)

This equation tells us that each CD costs $4.

By substituting this value into equation 1, we get:

4(4) + 2y = 32

16 + 2y = 32

2y = 16

y = 8 (Equation 4)

This equation tells us that each magazine costs $8.

So, Jason spent $4 for each CD and $8 for each magazine.

How do you solve this problem: you have a random number generator that in each trial generates a number in {1,2,…,n} uniformly at random. What’s the expected number of trials to see all of the n values at least k times? Specifically for k=log(n)

Answers

A base must be raised to a certain exponent or power, or logarithm, in order to produce a specific number.

How do you explain logarithm?

The exponent or power that must be added to a base to produce a particular number is called the logarithm. If bx = n, then the mathematical expression for x is x = logb n, where x is the logarithm of n to the base b. For instance, since 23 = 8, 3 is the logarithm of 8 in base 2, or 3 = log2 8.

The opposite of exponentiation in mathematics is the logarithm. The exponent to which b must be raised in order to obtain a number x is hence the logarithm of a number x to the base b. For instance, since 1000 = 103, log10 of 1000 is 3, or log10 = 3.

Common logarithms, with a base of 10, binary logarithms, with a base of 2, and natural logarithms, with a base of e 2.71828, are the four most popular varieties of logarithms.

Say you have n=4 and k=2. (Next, we might look at n=8 and k=3). Let f[(x-list_),y] be the expected value of the number of random trials needed to get from a list of thus and so many hits already, to completion with y or more hits in every slot. We want f[(0,0,0,0),2].

Note that f[anylist,0]=0, and that f[(0),1]=1.

Now f[0000,2]=1+f[0001,2], because the first random number has to go somewhere and whichever one it lands on is symmetric to the case where it lands on 4.

Next, f[0001,2]=1+(1/4)f[0002,2]+(3/4) f[0011,2]=1+(1/3)f[000,2]+(3/4)f[0011,2], the second step because once one slot is filled, it just takes 4/3 times as long to finish because 1/4 of your shots will be wasted on the saturated target.

By and by, you’ll encounter f[1111,2] among other situations, and this will be equal to f[0000,1].

It’s a finite calculation, it can be written up as a recursive program, and you’ll be able to get an exact answer for any f[(however many zeros), (whatever value counts as saturation)]. The calculation will, unfortunately, run into geometric expansion of time and space as there are going to be a lot of subcases to consider even for f[00000000,3]. Still, it’s nice to have the actual exact answer for a number of representative small cases.

As to the long term situation, once you’ve fired, say, n log n shots, you theoretically might be done, having `wasted no shots’. But consider the number of hits that “1” has got. This is a binomial distribution, with the probability of k hits out of n log n shots each at odds 1/n of hitting being Binomial[n log n, k](1/n)^k((n-1)/n)^(n log n-k). This should work out to roughly a Poisson distribution, with density something like (x/log n)e^{-x/log n} being the probability that you got x hits. The saturated targets would be the ones with x greater than log n, and you’d expect a typical target would need  ( log n - x )  e x / log n dx further hits.

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 7 hours of burning, a candle
has a height of 23.2 centimeters. After 26 hours of burning, its height is 15.6 centimeters. What is the height of the candle after 25 hours?

Answers

The height of the candle after 9 hours can be written as 23.4 cm.

What is a linear relationship?

The linear relationship is the relationship between two variables such that it follows a straight line.

As it is given that the height of the candle is linear to the amount of time. Now, let's the time be on the x-axis and the y-axis be the height of the candle. therefore, the slope of the linear relationship can be represented as,

Point1 of the slope, (x₁, y₁) = (6, 24.6)

Point2 of the slope, (x₂, y₂) = (21, 18.6)

Now, since we know the two points of the linear relationship, therefore, the slope can be written as,

m = (y2 - y1)/(x2-x1)

m = (18.9 - 24.6) / (21 - 6)

m = -0.4

Thus, the slope of the linear relationship is -0.4.

Now, the equation of the linear relationship can be written as,

y = mx + c

y1 = mx1 + c

24.6 = (-0.4 * 6) + c

24.6 = -2.4 + c

Thus, the Linear relationship of the candle height and the amount of time can be written as y = -0.4x + C.

Now, In order to calculate the height of the candle after 9 hours, we will substitute the value of the x as 9.

y = -0.4x + 27.

y = -0.4(9) + 27.

y = -3.6 + 27.

y = 23.4

Hence, the height of the candle after 9 hours can be written as 23.4 cm.

What is Higher-Order Thinking?

Higher-order thinking is a concept of educational reform based on learning taxonomies (like Bloom's taxonomy). Higher-order thinking skills are also known as higher order thinking skills (HOTS). The theory holds that some forms of learning have more universal advantages while requiring more cognitive effort than others.

Joel counts back from 79 to 65.

The numbers in descending order from 79 to 65 is -

79 78 77 76 75 74 73 72 71 70 69 68 67 66 65

The numbers go from right to left on a number line.

The options for the numbers are -

77 72 70 82 70 82 67 62 80

After applying HOTS the numbers which do not lie in between 79 and 65 when counting backwards is -

82 82 62 80

Therefore, the numbers which can be eliminated are 82 82 62 80.

Liam has quarters, dimes, and nickels in his pocket. Liam says he has twice as many quarters as dimes and 3 more dimes than nickels. Liam also says he has the same amount of money in dimes as he has in quarters.

How many of each coin does Liam have in his pocket?

Answers

Liam has 5 quarters, 10 dimes and  and 7 nickels.

What is quarter and dime?

1 dollar is 100 cents - a full dollar, so 100 cents.

One dollar is written on one side of the coin, sometimes as "$1".

1 quarter dollar equals 25 cents - 1/4 of a dollar equals 25%, so 25 cents

On one side of the coin, a quarter dollar is written.

1 dime is 10 cents - 1/10th of a dollar, so 10%, so 10 cents, dime begins with d, decimal begins with, and decimal is base-10. One dime is written on one side of the coin.

1 nickel is 5 cents - made of nickel alloy, 1 cent/penny is possibly not made of nickel because it costs more than 1 cent, so it begins with 5 cents.

On one side of the coin, five cents are written.

Let d be the no. of dimes, n be the no. of nickels and q be the no. of quarters.

Given that

2q = d

n + 3 = d

money in dimes = money in quarters

10d = 25q

d can be written as

d = q/2

So

10(2q)  = 25q

2q/q = 25/10

q = 2.5

as 2.5 cant be a number for quarter, lets double it

q = 5

d = 2q

d = 2(5)

d = 10

n = d - 3

n = 10 - 3

n = 7

Thus, Liam has 5 quarters, 10 dimes and  and 7 nickels.

I asked my daughter how many students are there in her class. She said it is equal to the sum of 3 consecutive natural numbers. Moreover, it is also equal to the sum of the two natural numbers following those 3 consecutive natural numbers. What is the answer to my questions?

Answers

Answer: Let's call the smallest of the 3 consecutive natural numbers "n". The other two numbers are "n+1" and "n+2". The sum of these 3 numbers is "3n + 3"

Also, the sum of the two numbers following these 3 consecutive natural numbers is (n+3) + (n+4) = 2n + 7

We know that these two expressions are equal:

3n + 3 = 2n + 7

By solving this equation we can find the value of n.

Subtracting 3 from both sides: 3n = 4

Dividing by 3: n = 4/3

Since n is a natural number, n has to be the integer 1.

So the three consecutive natural numbers are 1, 2, 3 and the sum of the students in the class is 6, which is also the sum of the next two natural numbers 4 and 5.

Therefore, there are 6 students in her class.

True or False: Scale factors figures must be the same proportions on all sides from the original figure.

Answers

The statement is true, the scale factor maintains the proportions between the sides.

Is the statement true or false?

We want to see if the statement "Scale factors figures must be the same proportions on all sides from the original figure." is true or false.

Suppose we have a polygon with N sides, such that the lengths of each side are:

{L₁, L₂, L₃,...}

If we apply a scale factor k, we just need to multiply each one of these lengths by k, then we will get:

{k*L₁, k*L₂, k*L₃,...}

Now, let's take the proportion between the new lengths for sides 1 and 2, we will get:

(k*L₁)/(k*L₂) = L₁/L₂

The scale factor disappears, then the proportions are maintained,

Answers

If the depth of the snow is 7 inches now, the depth one hour from now is equal to 8.5 Inches.

How to determine the depth one hour from now?

Based on the information provided above, a function which models the depth (D) in inches, of snow in a yard time (t) hours after it started snowing this morning is given by:

D = 1.5t + 4

where:

D represents the depth measured in inches.t represents the time measured in hours.

When the depth (D) in inches is equal to 7 inches now, the time measured in hours would be given by:

D = 1.5t + 4

7 = 1.5t + 4

1.5t = 7 - 4

1.5t = 3

The probability using the same formula as before: P(X>=3) = 1 - P(X<=2), which gives us 1 - 0.8530p = 0.08, or p = 0.0934.

Let p be the probability of a rivet being defective.  In order for 19% of all seams to need reworking, at least 4 of the 23 rivets must be defective.  This means that the probability of at least 4 of the rivets being defective must be 0.19.  We can calculate this probability using the formula P(X>=4) = 1 - P(X<=3), where X is a binomial random variable with parameters n = 23 and p = p.  This gives us 1 - 0.9920p = 0.19, or p = 0.1984.

To ensure that only 8% of all seams need reworking, at least 3 of the 23 rivets must be defective.  This means that the probability of at least 3 of the rivets being defective must be 0.08.  We can calculate this probability using the same formula as before: P(X>=3) = 1 - P(X<=2), which gives us 1 - 0.8530p = 0.08, or p = 0.0934.
