The function f(t) = 12(1+0.03) can be used to determine the population in thousands of a town t years

Answers

Answer 1

The population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.

To find the population of the town in 1955, enter t = 0 into the function f(t) = 12(1 + 0.03)t:

f(0) = 12(1 + 0.03)^0 = 12(1)

      = 12

As a result, the town's population in 1955 was 12,000 people.

We can compare the population at two successive years, t and t+1, to compute the percent increase in population from year to year.

[(Population at year t+1) - (Population at year t)] / (Population in t th year) * 100

Increase in Percentage = [f(t+1) - f(t)] / f(t) * 100

Increase in Percentage = [12(1 + 0.03)(t+1) - 12(1 + 0.03)t] / [12(1 + 0.03)^t] * 100

Because the function f(t) = 12(1 + 0.03)t depicts exponential growth, the annual population increase will be a constant percentage. The percentage increase in this scenario would be 3% since the growth factor is 1 + 0.03 = 1.03.

Therefore, the population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.

a goal of financial literacy for children is to learn how to manage money wisely. one question is; how much money do children have to manage? a recent study by schnur educational research associates randomly sampled 15 children between 8 and 10 years old and 18 children between 11 and 14 years old and recorded their monthly allowance. is it reasonable to conclude that the mean allowance received by children between 11 and 14 years is more than the allowance received by children between 8 and 10 years? use the .01 significance level.

Answers

We can reject the null hypothesis   since the p -value is less than 0.01. This means that there is enough   evidence to support the alternative hypothesis.

Why is this so ?

To compute the p-value,   we need the t test statistics.

t = (x1 - x2) / s / √(n1 +n2   - 2)

Where

x1 is the mean of the first group

x2 is the mean of the second group

s  is the pooled standard deviation

n1 is the sample size of the first group

n2 is the sample size of the second group

Calulation shows that the pooled standard deviation is s = $10.

Thus,

t = (25 - 42) / 10 / √(15 + 18 - 2)

= -0.30532901344

= -0.305

Since the p  -value is less than 0.01,we can reject the null hypothesis.

This means that there is enough evidence to support the alternative hypothesis that the mean allowance receivedby children between 11 and 14 years   is greater than the allowance received by children between 8 and 10 years.

The margin of error for this data set is 2.5%. What is the 95% confidence interval for those who say they felt fully engaged with their mortgage provider (rounded to 1 decimal place)?

Answers

The sample size for the Gallup poll is 1,627 adults. The 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).

To calculate the 95% confidence interval, we need to consider the margin of error. The margin of error is given as 2.5%, which means that we need to account for plus or minus 2.5% around the observed proportion of 22%.

First, let's calculate the margin of error:

Margin of Error = 2.5% of 22% = 0.025 * 22% = 0.0055

Next, we can calculate the lower and upper bounds of the confidence interval:

Lower Bound = 22% - Margin of Error = 22% - 0.0055 = 21.995% ≈ 22.0%

Upper Bound = 22% + Margin of Error = 22% + 0.0055 = 22.005% ≈ 22.0%

Therefore, the 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).

Answers

If we assume that the three measurements represent the sides of a cube, the surface area would be 8214 square feet.

To calculate the surface area of an object, we need more information about its shape.

Simply stating "37 ft" three times does not provide enough details to determine the surface area.

Surface area is typically calculated for three-dimensional objects such as cubes, spheres, cylinders, or prisms.

Each shape has a specific formula to calculate its surface area.

If we assume that all three measurements, 37 ft, represent the sides of a cube, we can calculate the surface area of the cube.

In a cube, all sides are equal in length.

The surface area of a cube is given by the formula: 6 [tex]\times[/tex] side [tex]\times[/tex] side, where "side" represents the length of one side of the cube.

In this case, if all sides of the cube measure 37 ft, we can substitute this value into the formula:

Surface Area = 6 [tex]\times[/tex] side [tex]\times[/tex] side

[tex]= 6 \times 37 ft \times37 ft[/tex]

[tex]= 6 \times 1369 ft^2[/tex]

Therefore, if we assume that the three measurements represent the sides of a cube, the surface area would be 8214 square feet.

However, without specifying the shape or providing additional information, it is not possible to determine the surface area accurately.

The theoretical probability, P(gold), is 25%, and the experimental probability is 25%.
The theoretical probability, P(gold), is 50%, and the experimental probability is 13.0%.

Answers

(1) The area of the actual bridge deck in square feet is  5,280 square feet.

(2) The theoretical probability, P(gold), is 25% and the experimental probability, P(gold), is 27.5%.

(1) To find the area of the actual bridge deck, we need to convert the dimensions of the scaled bridge deck from inches to feet, and then scale up by a factor of 60.

48 inches = 4 feet

4 and 2/5 inches = 0.3667 feet (rounded to four decimal places)

Area of the scaled bridge deck = 4 feet x 0.3667 feet = 1.4668 square feet

Scaling up by a factor of 60:

Area of actual bridge deck = 1.4668 square feet x 60^2 = 5,280.48 square feet

Therefore, the area of the actual bridge deck is approximately 5,280 square feet.

(2) Based on the given data,

The theoretical probability of pulling a gold marble from the bag is 25% since there are a total of 40 marbles and 11 of them are gold.

Meanwhile, the experimental probability is calculated by dividing the total number of marbles pulled by the number of times gold was pulled.

As a result, the accurate answer is that the theoretical probability, P(gold), is 25% and the experimental probability, P(gold), is 27.5%.

the time taken between john catching the ball and then throwing it to pierre is 2 seconds . the total time taken from ahmed to pierre in 7 seconds. write an equation to show that it simplifies to 2x^2-9x-2=0

Answers

Given statement solution is :- a) The expression for the time taken for the ball to reach John is:

Time1 = 10 / x.

b) The expression for the time taken for the ball to go from John to Pierre becomes:

Time2 = (10 / x) - 0.5

c) The equation with a positive x, we can multiply both sides by -1:

-1 * (2x^2 - 9x - 2) = 0

This simplifies to:

-2x^2 + 9x + 2 = 0

a) The time taken for the ball to reach John can be calculated using the formula:

Time = Distance / Speed

In this case, the distance is 10m and the speed is x m/s. Therefore, the expression for the time taken for the ball to reach John is:

Time1 = 10 / x

b) The time taken for the ball to go from John to Pierre can be calculated as:

Time2 = Time1 - 0.5

Since Time1 is already expressed as 10 / x, the expression for the time taken for the ball to go from John to Pierre becomes:

Time2 = (10 / x) - 0.5

c) Let's calculate the time taken by Ahmed to throw the ball to John, John to throw the ball to Pierre, and the time between John catching and throwing the ball.

Total time = Time1 + Time2 + 2

Given that the total time is 7 seconds, we can write the equation:

Time1 + Time2 + 2 = 7

Substituting the expressions for Time1 and Time2:

10 / x + (10 / x) - 0.5 + 2 = 7

Simplifying the equation:

(10 + 10 - 0.5x) / x + 2 = 7

(20 - 0.5x) / x + 2 = 7

Multiplying through by x to eliminate the denominator:

20 - 0.5x + 2x = 7x

Combining like terms:

1.5x - 20 = 7x

Bringing all terms to one side:

1.5x - 7x = 20

-5.5x = 20

Dividing by -5.5:

x = -20 / 5.5

Simplifying:

x = -4/11

To rewrite the equation with a positive x, we can multiply both sides by -1:

-1 * (2x^2 - 9x - 2) = 0

This simplifies to:

-2x^2 + 9x + 2 = 0

Given that 8 tan = 3 cos
a) Show that the above equation can be rewritten in the form 3 sin2 + 8 sin − 3 = 0
b) Hence solve, for 0 ≤ ≤ 90, the equation 8 tan 2 = 3 cos 2, giving your answers to 2 decimal places.​

Answers

The only solution for the equation 8 tan^2 θ = 3 cos^2 θ in the given Range is θ ≈ 19.47 degrees.

a) We are given the equation 8 tan θ = 3 cos θ.

Dividing both sides of the equation by cos θ, we have:

8 tan θ / cos θ = 3

Using the identity tan θ = sin θ / cos θ, we can substitute it into the equation:

8 (sin θ / cos θ) / cos θ = 3

Simplifying further, we get:

8 sin θ / cos^2 θ = 3

Now, multiplying both sides of the equation by cos^2 θ, we have:

8 sin θ = 3 cos^2 θ

Using the identity cos^2 θ = 1 - sin^2 θ, we can substitute it into the equation:

8 sin θ = 3(1 - sin^2 θ)

Expanding the equation, we get:

8 sin θ = 3 - 3 sin^2 θ

Rearranging the terms, we have:

3 sin^2 θ + 8 sin θ - 3 = 0

Therefore, we have successfully shown that the equation can be rewritten in the form 3 sin^2 θ + 8 sin θ - 3 = 0.

b) Now, let's solve the equation 3 sin^2 θ + 8 sin θ - 3 = 0.

To solve the quadratic equation, we can use factoring, quadratic formula, or other appropriate methods.

In this case, the equation factors as:

(3 sin θ - 1)(sin θ + 3) = 0

Setting each factor equal to zero, we have two equations:

3 sin θ - 1 = 0    or    sin θ + 3 = 0

For the first equation, solving for sin θ, we get:

3 sin θ = 1

sin θ = 1/3

Taking the inverse sine (sin^-1) of both sides, we find:

θ = sin^-1(1/3) ≈ 19.47 degrees (to 2 decimal places)

For the second equation, solving for sin θ, we have:

sin θ = -3

Since the range of sine is between -1 and 1, there are no solutions for this equation in the given range (0 ≤ θ ≤ 90 degrees).

Therefore, the only solution for the equation 8 tan^2 θ = 3 cos^2 θ in the given range is θ ≈ 19.47 degrees.

Answer:

m∪n = {0, 1, 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 25, 26, 28, 36, 49, 64}.

Step-by-step explanation:

To find the intersection (m∩n) of the set of square numbers less than 80 and the set of non-negative even numbers under 30, we need to find the numbers that are in both sets.

The set of square numbers less than 80 is: {0, 1, 4, 9, 16, 25, 36, 49, 64}

The set of non-negative even numbers under 30 is: {0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}

The numbers that are in both sets are: {0, 4, 16}

Therefore, m∩n = {0, 4, 16}.

To find the union (m∪n) of the set of square numbers less than 80 and the set of non-negative even numbers under 30, we need to find all the unique numbers that are in either set.

The set of square numbers less than 80 is: {0, 1, 4, 9, 16, 25, 36, 49, 64}

The set of non-negative even numbers under 30 is: {0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}

Combining both sets and removing duplicates, we get:

{0, 1, 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 25, 26, 28, 36, 49, 64}

Therefore, m∪n = {0, 1, 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 25, 26, 28, 36, 49, 64}.

[9]​

Answers

Step-by-step explanation:

Let's solve the given questions step by step:

1. Determine the equation of f:

From the given information, we know that the turning point of f is (1, 4). The general form of a quadratic function is f(x) = ax^2 + bx + c. We are given that f(x) = a(x + p)^2 + q, so let's substitute the values:

f(x) = a(x + p)^2 + q

Since the turning point is (1, 4), we can substitute x = 1 and f(x) = 4 into the equation:

4 = a(1 + p)^2 + q

This gives us one equation involving a, p, and q.

2. Determine the equation of g:

The equation of g is given as g(x) = 0.3x + p1.

3. Determine the coordinates of the x-intercept of g:

The x-intercept is the point where the graph of g intersects the x-axis. At this point, the y-coordinate is 0.

Setting g(x) = 0, we can solve for x:

0 = 0.3x + p1

-0.3x = p1

x = -p1/0.3

Therefore, the x-intercept of g is (-p1/0.3, 0).

4. For which values of x will f(x) ≥ g(x)?

To determine the values of x where f(x) is greater than or equal to g(x), we need to compare their expressions.

f(x) = a(x + p)^2 + q

g(x) = 0.3x + p1

We need to find the values of x for which f(x) ≥ g(x):

a(x + p)^2 + q ≥ 0.3x + p1

Simplifying the equation will involve expanding the square and rearranging terms, but since the equation involves variables a, p, and q, we cannot determine the exact values without further information or constraints.

To summarize:

We have determined the equation of f in terms of a, p, and q, and the equation of g in terms of p1. We have also found the coordinates of the x-intercept of g. However, without additional information or constraints, we cannot determine the exact values of a, p, q, or p1, or the values of x for which f(x) ≥ g(x).

If $84 interest was earned on $600 principal at a
7% interest rate, how long was the money in the account?

Answers

Answer:

The time is 2 years

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t= ? years

P= $600

A= $600 + $84 = $684

r = 0.07

substitute in the formula above

$684 = $600(1+(0.07)t)

solve for t

t = [(684/600) - 1]/0.07 = 2 years

Two concentric circles form a target. The radii of the two circles measure 8 cm and 4 cm. The inner circle is the bullseye of the target. A point on the target is randomly selected.

What is the probability that the randomly selected point is in the bullseye?

Enter your answer as a simplified fraction in the boxes.

$$

Answers

Answer:

Step-by-step explanation:

The area of the bullseye is the difference between the areas of the two circles:

Area of inner circle = π(4 cm)² = 16π cm²

Area of outer circle = π(8 cm)² = 64π cm²

Area of bullseye = Area of outer circle - Area of inner circle = 64π cm² - 16π cm² = 48π cm²

The total area of the target is the area of the outer circle:

Total area of target = π(8 cm)² = 64π cm²

So the probability of randomly selecting a point in the bullseye is:

Probability = (Area of bullseye) / (Total area of target)

Probability = (48π cm²) / (64π cm²)

Probability = 3/4

Therefore, the probability that the randomly selected point is in the bullseye is 3/4.

x = 24
Submit
x = 51
X = 6
X = 99

Answers

Answer: 3 ≤ 47

Step-by-step explanation:

The inequality given is 3 ≤ 47.

To determine the solutions to this inequality, we need to find the values of x that satisfy the inequality.

Looking at the options provided:

x = 24: This is not a solution because 24 is less than 47.

x = 51: This is a solution because 51 is greater than or equal to 47.

x = 6: This is not a solution because 6 is less than 47.

x = 99: This is a solution because 99 is greater than or equal to 47.

Therefore, the solutions to the inequality 3 ≤ 47 are x = 51 and x = 99.

Suppose we are interested in determining if the proportion of adults who own a cat is greater than 30%. We randomly select 68 adults and find that 22 own a cat. Use a 0.05 significance level to test the claim that the proportion of adults who own a cat is greater than 30%.
Determine the p-value.

Answers

The p-value is greater than the significance level of 0.05 do not have enough evidence to reject the null hypothesis.

We cannot conclude that the proportion of adults own a cat is greater than 30% based on the given data.

To determine the p-value in this scenario, we need to conduct a hypothesis test.

Let's define our hypotheses:

Null hypothesis (H0):

The proportion of adults who own a cat is equal to or less than 30%.

Alternative hypothesis (Ha):

The proportion of adults who own a cat is greater than 30%.

Next, we can calculate the test statistic using the sample data.

The test statistic for this situation is the z-score measures how many standard deviations the sample proportion is away from the hypothesized proportion under the null hypothesis.

Let's calculate the sample proportion of adults who own a cat:

[tex]\^p[/tex] = 22/68

≈ 0.3235

Now, we need to calculate the standard error measures the variability of the sample proportion:

SE = [tex]\sqrt{[(\^p(1-\^p))/n][/tex]

= √[(0.3235(1-0.3235))/68]

≈ 0.0584

To find the z-score, we use the formula:

z = [tex](\^p - P_0)/SE[/tex]

= (0.3235 - 0.30)/0.0584

≈ 0.4046

Using a standard normal distribution table or a statistical calculator, we can find the p-value associated with the calculated z-score.

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true.

For a one-tailed test with the alternative hypothesis stating that the proportion is greater than 30% want to find the area to the right of the z-score.

Consulting the standard normal distribution table find that the area to the right of 0.4046 is approximately 0.3431.

Write a recursive formula for the following sequence.


You are welcome to submit an image of handwritten work. If you choose to type then use the following notation to indicate terms; a_n and a_(n-1). To earn full credit be sure to share all work/calculations and thinking.




a_n = { \frac{3}{5}, \frac{1}{10}, \frac{1}{60}, \frac{1}{360} }

Answers

The recursive formula for the sequence an = { 3/5, 1/10, 1/60, 1/360 } is an = an-1 / (6 - n). So, the recursive formula for the sequence is an = an-1 / (6 - n).

The given sequence an = { 3/5, 1/10, 1/60, 1/360 } can be written as follows: a1 = 3/5

a2 = 1/10

a3 = 1/60

a4 = 1/360

To find the recursive formula for the sequence, we need to find an-1 and an.

We have, a2 = a1 / (6 - 2) = a1 / 4,

which gives us a1 = 4a2a3 = a2 / (6 - 3) = a2 / 3,

which gives us a2 = 3a3a4 = a3 / (6 - 4) = a3 / 2,

which gives us a3 = 2a4

Substituting these values in the above formula, we get: an = an-1 / (6 - n)a2 = a1 / 4 => a1 = 4a2a3 = a2 / 3 => a2 = 3a3a4 = a3 / 2 => a3 = 2a4

Substituting a1, a2, and a3 in the recursive formula, we get: a2 = a1 / 4 => a1 = 4a2 = 4/10 = 2/5a3 = a2 / 3 => a2 = 3a3 = 3/60 = 1/20.  a4 = a3 / 2 => a3 = 2a4 = 2/360 = 1/180. Therefore, the recursive formula for the sequence is an = an-1 / (6 - n).

the angle of elevation from the bottom of a slide to the top of the slide is 44 if the top of the slide sits 16 feet above the ground

Answers

The length of the slide is approximately 16.56 feet.

To solve this problem, we can use basic trigonometry.

The angle of elevation refers to the angle between the horizontal ground and the line of sight from the bottom of the slide to the top of the slide.

Given that the angle of elevation is 44 degrees and the height of the top of the slide is 16 feet, we can use the tangent function to find the length of the slide.

The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

The opposite side is the height of the slide (16 feet), and the adjacent side is the length of the slide that we want to find (let's call it x).

So, we have:

tan(44 degrees) = 16 feet / x

To solve for x, we rearrange the equation:

x = 16 feet / tan(44 degrees)

Using a calculator, we can find the value of the tangent of 44 degrees, which is approximately 0.9659.

Thus, we can calculate:

x = 16 feet / 0.9659

≈ 16.56 feet

Answers

The relation and equation that is modelled by the graph is y = x - 1.

To determine the relation and equation that is modelled by the graph, we must analyze the characteristics of the graph.The graph is a straight line that passes through the points (0, -1) and (4, 3).

The slope of the line can be determined by using the slope formula:slope = (y2 - y1) / (x2 - x1) = (3 - (-1)) / (4 - 0) = 4/4 = 1

Therefore, the slope of the line is 1. We can use the point-slope form of the equation of a line to determine the equation of the line.y - y1 = m(x - x1)

where y1 = -1, x1 = 0, and m = 1Substituting these values, we get:y - (-1) = 1(x - 0)y + 1 = x Simplifying this equation, we get the relation y = x - 1.
