The area of the waxed hardwood floor is 35/9 yards square.

The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here: Total area of the floor = 4³/₈ yards² and he waxed 8/9 part of the total area.

Now 8/9 of the total area is

Waxed area= 8/9×35/8   ( 4³/₈ =35/8)

                  =35/9

Thus the area in square units that Jahdiel waxed is 35/9 yards²

The equation of the line graph is y = -3/8x + 5/2

A line is defined as the shortest distance between two points. The equation of a line in slope intercept form is expressed as:"

y = mx + b where:

m is the slope

b is the intercept

Using the coordinate points (-4, 4) and (4, 1)

Slope = 1-4/4-(-4)
Slope = -3/8

Determine the y-intercept

1 = -3/8(4) + b

The time it takes a 100g sample of woosterium-21 to decay to 1/3rd of its original amount is 3.002 hours.

The initial amount of woosterium-21 (Ni) that is provided is 100g

The half life of woosterium-21 (t1/2) is given as 3 hours

The final time (t) is provided as 10 hours

The equation for half life is given by the equation:

Nt =  Ni * (1/2)^(t/t₁/₂)

Where, Nt = the final amount of woosterium-21 after 10 hours.

Therefore, Nt = 100 * (1/2)^(10/3) = 100 * 0.5^3.33 = 100 * 0.09944 = 9.944g

Let third life of woosterium-21 be t₁/₃

Substituting values in equation Nt =  Ni * (1/2)^(t/t₁/₂)

9.944 = 100 * (1/2)^(10/t₁/₃)

0.9944 = (1/2)^(10/t₁/₃)

Taking log on both sides,

log 0.9944 = 10/(t₁/₃) log 0.5

-1.0026 = 10/(t₁/₃) * (-0.301)

1.0026 = 3.01/(t₁/₃)

t₁/₃ = 3.002 hours

Therefore, the third life of woosterium-21 was found to be 3.002 hours.

The probability that both motors from the particular supplier are assigned to the first line is 1/126.

To explain this further, the numerator of the equation is the number of ways to choose two motors from the nine available, and the denominator is the number of ways to assign the nine motors to the three production lines. The denominator is calculated by multiplying the number of ways to assign three motors to the first line, three motors to the second line, and three motors to the third line. This is why the denominator is 3C2*3C2*3C2, which simplifies to 126.

Answer: 3/7

Step-by-step explanation:

The correct response is b. 47.06 minutes. the shortest wait time that would still be in the longest 15% of wait times is 47.06 minutes.

A minute is a unit of time equal to 60 seconds and one-sixtieth of an hour. (See leap second; certain uncommon minutes have 59 or 61 seconds.) The minute is acceptable for use with SI units even though it is not a SI unit. In mathematics, time is defined as a continuous and ongoing sequence of events that occur one after another in the past, present, and future. Time can be used to quantify, contrast, or even rank the length of events or the gaps between them. When you say something has to be done, you are emphatically stating that it should happen or be done right away.

Mean, μ[tex]=38.12[/tex]

Standard deviation,σ[tex]=8.63[/tex]

Waiting times that are longer are worse than those that are shorter. Therefore, the 15% of wait times that are the worst fall into this category. The inferred level of confidence is 0.85.

The z value corresponding to the right tail probability of 0.15 is

Only one student is expected receive an A for the exam.

The 68-95-99.7 rule states that for a normal distribution, 68% of the data falls within one standard deviation of the mean, 95% of the data falls within two standard deviations of the mean, and 99.7% of the data falls within three standard deviations of the mean.

In this case, the mean is 70 and the standard deviation is 10, so the range of scores that would be considered an "A" would be between 90 and 100.

We can calculate the number of standard deviations from the mean that the range 90 to 100 covers and use the 68-95-99.7 rule to estimate the percentage of students who would receive an "A".

For a score of 90, the number of standard deviations from the mean is (90 - 70) / 10 = 2.

For a score of 100, the number of standard deviations from the mean is (100 - 70) / 10 = 3.

So, the range of scores between 50 and 90 covers two standard deviations from the mean and between 40 and 100 covers three standard deviations from the mean. According to the 68-95-99.7 rule, 99.7% of the data falls within three standard deviations of the mean and 95% of the data falls within two standard deviations of the mean, so we would expect about (99.7% - 95%)/2 = 2.35% of the students to receive an "A".

With 50 students, we would expect approximately 50 * 0.0235 = 1.175 ≈ ` student to receive an "A". We can round up to the nearest whole number to get an estimate of 50 students.

Approximately 99.7% of the area under the normal distribution curve falls within 3 standard deviations above and below the mean.

It's important to note that these values apply to a standard normal distribution (mean = 0, standard deviation = 1).

Dependent variables are variables that are examined or evaluated as a part of a study.Participants' test scores would be the dependent variable in a study looking at how tutoring affects test results because that is what is being measured.

This equation, as its name implies, has a minimum of two independent variables and a minimum of two dependent variables. These illustrations can aid in your understanding of a challenging theory.

So, our equation becomes,

999( x- 181818) = 333x - 181818

999x - 181636182 = 333x - 181818

666x = 181454364
