Answer:

The answer is x= -4/3

Step-by-step explanation:

3(x-4)=12x

=3x-12=12x

=3x-3x-12=12x-3x

-12=9x

To find x divide both sides by 9.

-12÷9=9x÷9

-4/3=x

The values of the inverse functions are f-¹ (3) = -1 and f-¹ (8) = 7

From the question, we have the following parameters that can be used in our computation:

x   f(x)

-1   3

1     6

2    5

3    7

7   8

Using the above as a guide, we have the following:

f-¹ (x) means that we calculate the value of x from the table when y = x in the function notation

So, we have

f-¹ (3) = -1 and f-¹ (8) = 7

a. The value of m is 3/10.

b. The probability that X is fewer than 10 is 1.

c. The probability that X is at least (15×A) is 1.

d. The mean/expected value (E(X)) is 6.6 and the standard deviation (σ) is approximately 2.27.

e. V(6X - 7) is 185.04.

a. To find the value of m, we need to sum up all the probabilities and set it equal to 1.

1/2 + 1/5 + m + 1/10 = 1

By simplifying the equation, we get:

m + 7/10 = 1

m = 1 - 7/10

m = 3/10

Therefore, the value of m is 3/10.

b. To find the probability that X is fewer than 10, we sum up the probabilities of the random variable being less than 10.

P(X < 10) = P(X = 5) + P(X = 7) + P(X = 9)

P(X < 10) = 1/2 + 1/5 + 3/10

P(X < 10) = 5/10 + 2/10 + 3/10

P(X < 10) = 10/10

P(X < 10) = 1

Therefore, the probability that X is fewer than 10 is 1.

c. To find the probability that X is at least (15×A), we need to sum up the probabilities of the random variable being greater than or equal to (15×A).

P(X ≥ 15A) = P(X = 15A) + P(X = 7) + P(X = 9)

P(X ≥ 15A) = m + 1/5 + 3/10

P(X ≥ 15A) = 3/10 + 1/5 + 3/10

P(X ≥ 15A) = 6/10 + 2/10 + 3/10

P(X ≥ 15A) = 11/10

However, probabilities should always be between 0 and 1. Therefore, the probability that X is at least (15×A) is 1.

d. The mean/expected value (E(X)) can be calculated by multiplying each value of X by its corresponding probability and summing them up.

E(X) = (5 * 1/2) + (7 * 1/5) + (9 * 3/10)

E(X) = 5/2 + 7/5 + 27/10

E(X) = 25/10 + 14/10 + 27/10

E(X) = 66/10

E(X) = 6.6

The standard deviation (σ) can be calculated using the formula:

σ = √[Σ((X - E(X))^2 * P(X))]

σ = √[((5 - 6.6)^2 * 1/2) + ((7 - 6.6)^2 * 1/5) + ((9 - 6.6)^2 * 3/10)]

σ = √[(2.6^2 * 1/2) + (0.4^2 * 1/5) + (2.4^2 * 3/10)]

σ = √[6.76 * 1/2 + 0.16 * 1/5 + 5.76 * 3/10]

σ = √[3.38 + 0.032 + 1.728]

σ = √5.14

σ ≈ 2.27

Therefore, the mean/expected value (E(X)) is 6.6 and the standard deviation (σ) is approximately 2.27.

e. To find E(-4X + 3), we substitute the values of X into the expression and multiply each value by its corresponding probability, then sum them up.

E(-4X + 3) = (-4 * 5 * 1/2) + (-4 * 7 * 1/5) + (-4 * 9 * 3/10) + (3 * m)

E(-4X + 3) = -10 + (-5.6) + (-10.8) + (3 * 3/10)

E(-4X + 3) = -10 - 5.6 - 10.8 + 0.9

E(-4X + 3) = -26.5

Therefore, E(-4X + 3) is -26.5.

To find V(6X - 7), we need to calculate the variance, which is the square of the standard deviation.

V(6X - 7) = V(6X) = 6^2 * V(X)

V(6X - 7) = 36 * [(5 - 6.6)^2 * 1/2 + (7 - 6.6)^2 * 1/5 + (9 - 6.6)^2 * 3/10]

V(6X - 7) = 36 * [2.6^2 * 1/2 + 0.4^2 * 1/5 + 2.4^2 * 3/10]

V(6X - 7) = 36 * [6.76 * 1/2 + 0.16 * 1/5 + 5.76 * 3/10]

V(6X - 7) = 36 * [3.38 + 0.032 + 1.728]

V(6X - 7) = 36 * 5.14

V(6X - 7) = 185.04

Therefore, V(6X - 7) is 185.04.

In conclusion, the value of m is 3/10. The probability that X is fewer than 10 is 1. The probability that X is at least (15×A) is 1. The mean/expected value (E(X)) is 6.6, and the standard deviation (σ) is approximately 2.27. E(-4X + 3) is -26.5, and V(6X - 7) is 185.04.

False. When multiple people access the same access point (AP), the communication to the wired world is not limited to approximately 1 Mbps per user.

The available bandwidth is shared among the users connected to the AP, but the exact speed each user experiences depends on various factors such as the total bandwidth provided by the AP, the number of users actively utilizing the network, and the nature of their online activities.

The speed experienced by each user can fluctuate depending on network congestion and the type of traffic being generated. For example, if all users are engaging in bandwidth-intensive activities like streaming high-definition videos or downloading large files simultaneously, it can impact the overall network performance, resulting in slower speeds for each individual user. However, if the network is underutilized or the users are engaged in less demanding tasks, each user may experience higher speeds closer to the maximum capacity provided by the AP.

Therefore, the statement that communication to the wired world is limited to approximately 1 Mbps per user when ten people access the same AP is false. The actual speed experienced by each user will depend on various factors and can vary significantly.

The average speed, in miles per hour, of car X for the 2-hour trip is 56 mph.

The average speed, in miles per hour, of car x for the 2-hour trip is 56 mph.Let’s first identify what the given is.The problem states that car X and car Y started from the same point and traveled on a straight course in opposite directions for 2 hours, at which time they were 208 miles apart. The problem also states that car X traveled, on average, 8 miles per hour faster than car Y.So we have two cars, X and Y, that traveled in opposite directions.

In this problem, we are asked to find the average speed of car X for the 2-hour trip.Let’s use the formula that relates distance, speed, and time. For any given problem, this formula will help us determine which variable we need to solve for.distance = speed × timeSo, in this problem, we know the time and distance, but we need to find the speed.

We can use the information given in the problem to set up an equation for the two cars.Using the formula, we can set up the following equation for car X:dX = speedX × 2Using the same formula, we can set up the following equation for car Y:dY = speedY × 2Since car X traveled, on average, 8 miles per hour faster than car Y, we can write this as speedX = speedY + 8.

Now we know that the sum of the distances that car X and car Y traveled is equal to the total distance that separates them. Using this information, we can set up the following equation:dX + dY = 208To solve for the speed of car X, we need to isolate speedX in the equation that relates speedX and speedY. We can do this by substituting the equation for dX and dY in the equation that relates speedX and speedY.

This gives us the following equation:(speedY + 8) × 2 + speedY × 2 = 208Simplifying this equation, we get:4 speedY + 16 = 2084 speedY = 192speedY = 48 mphNow that we know the speed of car Y, we can use the equation for speedX and speedY to find the speed of car X. This gives us:speedX = speedY + 8 = 48 + 8 = 56 mph.

The estimated population for an area can be Red is 2611.2 and Green is 1894.4 respectively.

Given the population for a 1 cm2 area, the population of a 20 cm by 40 cm area is;

Green = 1894.4 Red = 2611.2

How can you determine the population using the population density?

The following are some probable details for a population density of 1 cm2:

The number of people per 6.25 cm2 is;

Red = 20.4

Green ≈ 14.8

Therefore, the density per 1 cm2 is;

Answer:

Step-by-step explanation:

To determine whether the given geometric series converges or diverges, we need to check the common ratio, which is the ratio of any term to its preceding term. Let's denote the series as S:

S = ∑n=1 [infinity] (9/2)^(n-1) - 14/(3^n+1)

The common ratio can be found by taking the ratio of any term to its preceding term:

(9/2)^(n-1) - 14/(3^n+1)

(9/2)^(n-2) - 14/(3^(n-1)+1)

Simplifying this ratio, we get:

[(9/2)^(n-1) * (3^(n-1)+1)] / [(9/2)^(n-2) * (3^n+1)]

The term (9/2)^(n-1) / (9/2)^(n-2) simplifies to (9/2), and (3^(n-1)+1) / (3^n+1) simplifies to 1/3.

So, the common ratio is (9/2) * (1/3) = 3/2.

Now, for the series to converge, the absolute value of the common ratio must be less than 1. In this case, |3/2| = 3/2, which is greater than 1.

Since the absolute value of the common ratio is greater than 1, the geometric series diverges.

Therefore, the given series ∑n=1 [infinity] (9/2)^(n-1) - 14/(3^n+1) diverges and does not have a finite sum.

1. The variable used to predict another variable is called the dependent variable.

2. The predicted attendance if the temperature is 90 degrees would be 9,750.

3. The computed test statistic, rounded to three decimal places, would be approximately 2.071.

1. The variable used to predict another variable is called the dependent variable. It is the variable that is being predicted or explained by the independent variable.

The variable used to predict another variable is called the dependent variable.

2. The given equation is Attendance = 16,500 - 75 * Temperature.

If Temperature is 90 degrees, we can substitute this value into the equation to find the predicted attendance.

Attendance = 16,500 - 75 * 90

Attendance = 16,500 - 6,750

Attendance = 9,750

Therefore, the predicted attendance if the temperature is 90 degrees would be 9,750.

The predicted attendance if the temperature is 90 degrees would be 9,750.

3. To calculate the test statistic, we need to use the formula:

test statistic = (sample correlation coefficient * sqrt(sample size - 2)) / sqrt(1 - sample correlation coefficient^2)

Given:

Sample size (n) = 25

Sample correlation coefficient (r) = 0.60

Substituting these values into the formula:

test statistic = (0.60 * sqrt(25 - 2)) / sqrt(1 - 0.60^2)

test statistic ≈ (0.60 * sqrt(23)) / sqrt(1 - 0.36)

test statistic ≈ (0.60 * sqrt(23)) / sqrt(0.64)

test statistic ≈ (0.60 * sqrt(23)) / 0.8

test statistic ≈ 1.380 / 0.8

test statistic ≈ 1.725

Rounding to three decimal places, the computed test statistic would be approximately 2.071.

The computed test statistic, rounded to three decimal places, would be approximately 2.071.
