No, because with a sample size of 10, the heavily skewed population distribution will not allow for a nearly normal distribution of sample means.

With a sample size of 10, the heavily skewed population distribution will not allow for a nearly normal distribution of sample means. This is because the sample size is too small and the skewed population distribution will not have enough data to accurately represent the overall population. With a sample size of 10, the sample means will be heavily influenced by outliers and extreme values, which will lead to a histogram that is skewed and not nearly normal. Therefore, no matter how slightly skewed the population distribution is, a sample size of 10 is not large enough to create a normal distribution of sample means.

The degree of agreement among observers can be established by using a statistical measure of Inter rater reliability (Option c is correct)

Interrater reliability describes how closely two or more people agree.

Because everyone has used it, interrater reliability is the easiest type of reliability to comprehend. For instance, watching a judged event like dog shows or Olympic ice skating depends on human observers upholding a high level of consistency across observers.

Higher values of Kendall's coefficient, which ranges from 0 to 1, suggest more inter-rater reliability. Excellent values are greater than 0.9, and a value of 1 denotes perfect agreement. For the purpose of testing hypotheses, statistical software can compute confidence ranges and p-values.

The primary purpose of the passage is to caution against uncritical embrace of nuclear fusion power as a major energy source.

Nuclear fission generates a significant amount of radioactive waste, which can be hazardous and needs to be stored securely for a long period of time. Nuclear fusion waste has a lower radioactivity and decays significantly more quickly. Fossil fuels like gas and oil are not required for nuclear fusion.

Radiation that is released voluntarily is referred to as radioactivity. An atomic nucleus that is unstable for some reason accomplishes this by "wanting" to give up some energy in order to change its configuration to one that is more stable.

The passage begins by classifying as misconceptions favorable views about nuclear fusion power and finishes by recommending the use of current energy sources going forward rather than nuclear fusion power. All of this adds up to the text trying to warn against uncritically embracing nuclear fusion power as a major source of energy.

The time at which the two cars will be 170 miles apart is; 1.619 hours

Let us write an equation for each car as;

d₁ = r₁*t₁ (northbound)

d₂ = r₂*t₂ (southbound)

They both start at the same time, and will stop them both when they are 170 miles apart. Thus;

t = d₁/r₁

t = d₂/r₂

Thus, the equation to find their times is;

d₁/r₁ = d₂/r₂

d₁ = d₂r₁ /r₂

Thus;

d₁ + d₂ = 170

d₁ = 170 - d₂

Similarly, r₁ = 45 mph and r₂ = 40 mph

170 - d₂ = d₂(45/60)

4(170 - d₂) =3d₂

7d₂ = 680

d₂ = 680/7

d₂ = 97.143 miles

d₁ = 170 - 97.143

d₁ = 72.857 miles

The lateral surface area of the walls of the warehouse is 18,000 sq ft.

Area is a measure of the size of a surface or the amount of space that a two-dimensional shape occupies. It is typically measured in square units, such as square feet or square meters. The area of a shape is calculated by multiplying the length and width of the shape together.

To find the lateral surface area of the walls of the warehouse, you need to find the combined area of all the exterior walls. To do this, you can use the formula for lateral surface area, which is:

Lateral Surface Area = 2 * (l * h + w * h)

where l is the length of the wall, w is the width of the wall, and h is the height of the wall.

Using this formula, we can find the lateral surface area of each wall and add them together to get the total lateral surface area:

Wall 1: Lateral Surface Area = 2 * (100 ft * 30 ft) = 6,000 sq ft

Wall 2: Lateral Surface Area = 2 * (200 ft * 30 ft) = 12,000 sq ft

Total Lateral Surface Area = 6,000 sq ft + 12,000 sq ft = 18,000 sq ft

Answer:

1 - (5/6)x = 2y

Step-by-step explanation:

To write the equation y = 5/12x - 1/2 in standard form, we need to first get rid of the fractions by multiplying both sides of the equation by the least common denominator of the fractions, which in this case is 12. This gives us the equation 12y = 5x - 6. Next, we can rearrange the terms on the right-hand side of the equation to get 6 - 5x = 12y. Finally, we can divide both sides of the equation by 6 to get the equation in standard form, which is 1 - (5/6)x = 2y. The standard form of the equation is thus 1 - (5/6)x = 2y.

Answer:

5/12x = y - 6

Step-by-step explanation:

To write the equation y = 5/12x - 1/2 in standard form, we need to first move all the terms that contain x to one side of the equation and all the constants to the other side. This will give us the equation 5/12x - y = -1/2. Next, we need to multiply both sides of the equation by the denominator of the fraction on the right-hand side to eliminate the fraction. This gives us 5/12x - y = -6. Finally, we need to add y to both sides of the equation to obtain the standard form of the equation, which is 5/12x = -6 + y. This can be written more concisely as 5/12x = y - 6. Therefore, the equation y = 5/12x - 1/2 can be written in standard form as 5/12x = y - 6.

The amount of the last payment that Elroy will make is $710, which includes the $200 monthly payment and a balance of $510.

The last payment amount is the result of the mathematical operations of subtraction and multiplication.

The first mathematical operation was the subtraction of the down payment from the total cost of the video game system.

Using multiplication, the monthly payments are determined to be $3,400 for 17 months.  This is subtracted from the remaining balance to obtain the last payment amount.

The cost of a custom video game/virtual sound system = $4,210

Down payment = $100

The remaining balance for monthly payment = $4,110 ($4,210 - $100)

Payment period = 18 months (1¹/₂ years)

Monthly payments = $200

Payment for the first 17 months = $3,400 (17 x 200)

Last payment = $710 ($4,110 - $3,400)
