We know that the area of a parallelogram is given by the formula A = bh, where A is the area, b is the base, and h is the height. In this case, we are given the area and the base, and we need to find the height.

We can rearrange the formula to solve for h: h = A/b

Plugging in the given values, we get:

h = 14.4 sq ft / 4.5 cm

Note that the units are different for area and base, so we need to convert them to the same units. Let's convert the base to feet, since the area is given in square feet:

h = 14.4 sq ft / (4.5 cm / 30.48 cm/ft) [converting cm to ft]

h = 14.4 sq ft / 0.148 ft

h ≈ 97.3 cm

Therefore, the height of the parallelogram is approximately 97.3 cm.

The length of the room on the blueprint is 12 inches.

what is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

To solve this problem, we first need to find the length of Jean's bedroom in real life.

Let L be the length of Jean's bedroom in real life. According to the problem, the width of the room is 9 feet, so we can write:

9 = 0.25x, where x is the width of the room on the blueprint.

Solving for x, we get:

x = 9/0.25 = 36

So the width of the room on the blueprint is 36 inches.

Since the width of the room on the blueprint is 75% of its length, we can write:

36 = 0.75L

Solving for L, we get:

L = 36/0.75 = 48

So the length of Jean's bedroom in real life is 48 feet.

To find the length of the room on the blueprint, we use the same scale of 0.25 inch = 1 foot. Therefore:

1 foot = 0.25 inch on the blueprint

48 feet = 48 x 0.25 = 12 inches on the blueprint

Therefore, the length of the room on the blueprint is 12 inches.

Probability is a gauge of how likely an occurrence is to occur. It is represented by a figure between 0 and 1, with 0 representing an unlikely occurrence and 1 representing an inevitable event. Switching a fair coin and coin turns has a chance of 0.5 or 50% because there are two equally likely results. (Heads or tails). Probability theory is a branch of mathematics that studies random occurrences rather than their characteristics. It is applied in many areas, including statistics, economics, science, and engineering.

There are three equally probable results from the spinner: 1, 2, and 3. To determine the likelihood of receiving an odd or divisor of 54, we must tally the number of events that meet this requirement.

54 has divisors of 1, 2, 3, 6, 9, 18, 27, and 54. Only one, three, and nine are unusual. As a result, the potential results that are either odd or divisors of 54 are 1, 3, and 2.

P(odd or divisor of 54) = P(1) + P(2) + P(3) + P(9) = 1/3 + 1/3 + 1/3 + 0 (because 9 is not a spinning choice) = 1

the expectation of the game is $0.22 per game. This means that on average, for every game played, the player can expect to win $0.22. However, this does not guarantee that the player will actually win $0.22 every time they play the game. It simply means that over many plays of the game, the player's winnings will average out to $0.22 per game.

How to solve the probability?

To find the expectation of the game, we need to calculate the probability of winning and losing and multiply them by their corresponding payoffs.

First, let's calculate the probability of rolling a sum of 2 or 12. There is only one way to roll a sum of 2 or 12, which is by rolling a pair of ones or a pair of sixes, respectively. So, the probability of rolling a sum of 2 or 12 is:

P(2 or 12) = P(1,1) + P(6,6) = (1/6) * (1/6) + (1/6) * (1/6) = 1/18

Next, let's calculate the probability of rolling a 7. There are six ways to roll a sum of 7, which are: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). So, the probability of rolling a 7 is:

P(7) = P(1,6) + P(2,5) + P(3,4) + P(4,3) + P(5,2) + P(6,1) = 6 * (1/6) * (1/6) = 1/6

Finally, the probability of losing is:

P(loss) = 1 - P(2 or 12) - P(7) = 1 - 1/18 - 1/6 = 11/18

Now, we can calculate the expectation of the game as follows:

E(X) = (12 * P(2 or 12)) + (5 * P(7)) - (1 * P(loss))

= (12 * 1/18) + (5 * 1/6) - (1 * 11/18)

= 2/9 + 5/6 - 11/18

= 0.22

So, the expectation of the game is $0.22 per game. This means that on average, for every game played, the player can expect to win $0.22. However, this does not guarantee that the player will actually win $0.22 every time they play the game. It simply means that over many plays of the game, the player's winnings will average out to $0.22 per game.

Years Since Purchase

To better understand the exponential function that models the data, let's break it down:

y = 10.92 * 1.50ˣ

The constant "10.92" represents the initial value of the boat when it was purchased. This means that the boat was worth $10.92 when Michael first bought it.

The constant "1.50" represents the growth factor of the boat's value. This means that each year, the value of the boat increases by a factor of 1.50.

The variable "x" represents the number of years since the boat was purchased. The function takes this input and returns the value of the boat at that time.

For example, if we plug in x=1 into the function, we get:

y = 10.92 * 1.50¹

y = 16.38

This means that after one year since the purchase, the boat was worth $16.38. Similarly, if we plug in x=2 into the function, we get:

y = 10.92 * 1.50²

y = 24.57

This means that after two years since the purchase, the boat was worth $24.57.

It's important to note that the exponential function assumes that the growth rate remains constant over time. In reality, the value of the boat may be affected by other factors such as wear and tear, maintenance, and market fluctuations. Nevertheless, the exponential function provides a useful model for understanding the trend in the data and making predictions about the future value of the boat.

1. First, we need to find the volume of the hemisphere bowl:

V_bowl = (2/3)πr^3

V_bowl = (2/3)π(6 cm)^3

V_bowl = 288π cm^3

Since water fills two-fifths of the volume, we can find the volume of water:

V_water = (2/5)V_bowl

V_water = (2/5)(288π cm^3)

V_water = 115.2π cm^3

2. Now, we need to find the radius and height of the cone to which the water is poured. Let's call the radius of the cone r and the height h. We know that the volume of the cone is equal to the volume of the water in the bowl:

V_cone = V_water

(1/3)πr^2h = 115.2π

r^2h = 345.6

We also know that the depth of the water in the cone is 12 cm, so h = 12 cm. Substituting this value into the equation above, we get:

r^2(12 cm) = 345.6

r^2 = 28.8

r ≈ 5.36 cm

So, the radius of the cone is approximately 5.36 cm, and the height is 12 cm.

The probability that a passenger is traveling for business is 67.1%.

The probability of a passenger bringing a laptop on a flight if the passenger is traveling for business is 0.352 or approximately 35.2%.

The probability that a passenger is traveling for business can be calculated by adding the number of passengers traveling for business and dividing by the total number of passengers:

P(traveling for business) = (274 + 397) / 1000 = 0.671

Therefore, the probability that a passenger is traveling for business is 0.671 or approximately 67.1%.

b. The probability of a passenger bringing a laptop on a flight if the passenger is traveling for business can be calculated as follows:

P(laptop | traveling for business) = number of passengers with a laptop and traveling for business / number of passengers traveling for business

P(laptop | traveling for business) = 236 / 671 = 0.352

Therefore, the probability of a passenger bringing a laptop on a flight if the passenger is traveling for business is 0.352 or approximately 35.2%.

To estimate the mean age, we need to find the midpoint of each age range and multiply it by the number of individuals in that range. Then we add up these products and divide by the total number of individuals:

Mean age = [(1+10)/2 x 35 + (11+20)/2 x 22 + (21+30)/2 x 20 + 35.5 x 7] / 84

= (5.5 x 35 + 15.5 x 22 + 25.5 x 20 + 35.5 x 7) / 84

= 16.1

Therefore, the estimated mean age of this extended family group is 16.1 years.

To calculate the sample variance, we need to find the deviation of each age from the mean, square each deviation, and add up these squared deviations. Then we divide this sum by the total number of individuals minus one:

s2 = [(1-16.1)2 x 35 + (11-16.1)2 x 22 + (21-16.1)2 x 20 + (35.5-16.1)2 x 7] / (84-1)

= (2254.05 + 537.08 + 220.89 + 253.68) / 83

= 50.47

Therefore, the estimated sample variance is 50.47 square years.

We simply take the square root of the sample variance to calculate the sample standard deviation:

s = [tex]\sqrt{s2}[/tex]
