Fill in the scale dimensions in the table to the nearest thousandth. The scale of a blueprint is 1/4 inch = 1 foot. A house has 1 bedroom measuring 10 feet 6 inches by 11 feet, a living room measuring 25 feet by 18 feet 8 inches, a kitchen measuring 13 feet 6 inches by 8 feet, and a dining room measuring 12 feet by 10 feet. Put the shortest length in the first box for each room. Give all answers to three decimal places (thousandths place).

The scale dimensions of the rooms on the blueprint using a scale of 1/4 inch = 1 foot are calculated by converting feet to inches, then dividing by the scale ratio (0.25 inches per foot) to find each room's dimensions in inches on the blueprint.
To calculate the scale dimensions of the rooms on the blueprint, you will use the given scale of 1/4 inch = 1 foot. This means for every 1/4 inch on the blueprint, it represents 1 foot in actual size.
Step-by-Step Calculation for Each Room
Convert the scale into a ratio that can be used for calculations (1/4 inch / 1 foot or 0.25 inches / 12 inches since there are 12 inches in a foot).
Calculate the scale dimension for each room by dividing the actual dimension in inches by the scale ratio.
For each room, ensure to convert feet to inches first (1 foot = 12 inches) and then apply the scale.
Bedroom: 10 feet 6 inches is (10 * 12) + 6 = 126 inches, 11 feet is (11 * 12) = 132 inches. Scale dimensions: (126 inches / 48) by (132 inches / 48) equals 2.625 inches by 2.750 inches.Living room: 25 feet is (25 * 12) = 300 inches, 18 feet 8 inches is (18 * 12) + 8 = 224 inches. Scale dimensions: (300 inches / 48) by (224 inches / 48) equals 6.250 inches by 4.667 inches.Kitchen: 13 feet 6 inches is (13 * 12) + 6 = 162 inches, 8 feet is (8 * 12) = 96 inches. Scale dimensions: (162 inches / 48) by (96 inches / 48) equals 3.375 inches by 2.000 inches.Dining room: 12 feet is (12 * 12) = 144 inches, 10 feet is (10 * 12) = 120 inches. Scale dimensions: (144 inches / 48) by (120 inches / 48) equals 3.000 inches by 2.500 inches.Below is the scale dimensions for each room to the nearest thousandth:

a. -8
b. 8
c. 34
d. 50
Answer:
D. 50
Step-by-step explanation:
[tex]f(x) = 9x - 7 \\ g(x) = 2x {}^{2} - 3x + 1 \\( f + g)(x) = 9x - 7 + (2x {}^{2} - 3x + 1) \\ (f + g)(x) = 2x {}^{2} + 6x - 6 \\ (f + g)(4) = 2(4 ){}^{2} + 6(4) - 6 \\ (f + g)(4) = 32 + 24 - 6 \\ (f + g)(4) = 56 - 6 \\ (f + g)(4) = 50[/tex]
Una was asked to write about predicting population means by taking the means of samples. She recorded a list of some statements generated from her classmates. Which statements are true? Check all that apply. The best prediction of the population mean is the value that falls between the least and greatest sample means. It is unlikely that the population mean will be the least or greatest mean from the samples. If the means of different samples are close in number, or have small variation, then they cannot be used to make predictions for the actual population. A more accurate prediction of the population mean can be made by decreasing the number of random samples. Samples are a random selection of data values from a population. To find the range of the sample means, subtract the least value from the greatest value.
Answer:
1, 2, and 5.
Step-by-step explanation:
The best prediction of the population mean is the value that falls between the least and greatest sample means.
It is unlikely that the population mean will be the least or greatest mean from the samples.
To find the range of the sample means, subtract the least value from the greatest value.
Hope that is helpful ¯\_(ツ)_/¯

Bluesky air has the best on-time arrival rate with 80% of its flights arriving on time. a test is conducted by randomly selecting 16 bluesky air flights and observing whether they arrive on time. what is the probability that 2 flights of bluesky air arrive late? (please carry answers to at least six decimal places in intermediate steps. give your final answer to the nearest four decimal places).
The problem can be solved by using the binomial probability formula. We know that the binomial model deals with the probability of success of an event in a series of experiments. Plug the values into the binomial formula to find the probability that 2 flights out of 16 selected flights will arrive late.
Explanation:This problem can be solved using the binomial probability formula. The binomial distribution model deals with finding the probability of success of an event that has only two possible outcomes in a series of experiments, such as a coin toss.
Given that the probability of a flight arriving on time is 80%, the probability (p) for a flight arriving late is 20% or 0.2. We are looking for the probability that 2 out of 16 flights arrive late. This is a binomial problem where n=16 (the number of trials), k=2 (the number of successes), and p=0.2 (probability of success).
The binomial formula is P(X=k) = C(n, k) * (p^k) * (1-p)^(n-k)
where C(n, k) is a combination that calculates the number of possible combinations of n items taken k at a time, without regard to the order of selection.
So, to solve this problem:
First, calculate C(16, 2).Second, calculate (0.2^2).Third, calculate ((1-0.2)^(16-2)).Lastly, multiply those three results together to get the final probability.The probability that 2 flights out of 16 selected flights will arrive late can be computed by plugging these values into the binomial formula.

In ancient Egypt, surveyors made right angles by stretching a rope with evenly spaced knots as shown. Explain why the ropes forms a right angle
In ancient Egypt, surveyors made right angles by stretching a rope with evenly spaced knots. The tensions in the rope on either side of the right angle were equal, resulting in the formation of a right angle.
Explanation:In ancient Egypt, surveyors made right angles by stretching a rope with evenly spaced knots. The ropes formed a right angle because the angles on either side of the rope were equal. When the rope was stretched taut, the tensions in the rope on either side of the right angle were equal. This resulted in the formation of a right angle.
Barbara is building a wooden cabin. The cabin is 42 meters wide. She obtained a bunch of 27 meters long wooden beams for the roof of the cabin. Naturally, she wants to place the roof beams in such an angle that each pair of opposite beams would meet exactly in the middle. What is the angle of elevation, in degrees, of the roof beams?
The angle of elevation is 38.9° if Barbara is building a wooden cabin. The cabin is 42 meters wide. She obtained a bunch of 27 meters long wooden beams for the roof of the cabin.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
Width of the cabin = 42 meters
Wooden beam length = 27 meters
Since opposite beams would meet exactly in the middle.
The half of the beam width = 42/2 ⇒ 21 meters
As we can see in the right angle triangle:
[tex]\rm cosx = \frac{21}{27}[/tex]
[tex]\rm x = cos^{-1}(\frac{21}{27} )[/tex]
x = 38.9°
Thus, the angle of elevation is 38.9° if Barbara is building a wooden cabin. The cabin is 42 meters wide. She obtained a bunch of 27 meters long wooden beams for the roof of the cabin.
