A sampling distribution is constructed based on a sample size of 9. if the sampling distribution has a mean of 500 and a standard error of 15, what is the standard deviation of the original comparison population
The standard deviation of the original comparison population is 45.
Explanation:The standard deviation of the original comparison population can be calculated using the formula:
Standard deviation of the sampling distribution = standard error * sqrt(sample size)
Given that the standard error of the sampling distribution is 15 and the sample size is 9, we can substitute these values into the formula:
The standard deviation of the original comparison population can be determined by using the relationship between the standard deviation, standard error, and sample size in a sampling distribution. The formula is:
[tex]\[ \text{Standard deviation of the original comparison population} = \text{Standard error} \times \sqrt{\text{Sample size}} \][/tex]
Given a standard error of 15 and a sample size of 9, substitute these values into the formula:
\[ \text{Standard deviation of the original comparison population} =[tex]15 \times \sqrt{9} = 15 \times 3 = 45 \][/tex]
Therefore, the standard deviation of the original comparison population is 45.
Standard deviation of the original comparison population = 15 * sqrt(9) = 15 * 3 = 45
Therefore, the standard deviation of the original comparison population is 45.

UW=VW
UV=UK
JK=2VW
UW=12KL
UV¯¯¯¯¯∥JL¯¯¯¯¯
The only correct statements in relation to the given triangle are;
JK = 2VW
UV ║ JL
1) UW = VW; This is not correct because we see that UW forms a parallel line to KV but there is nothing to show about it being equal to VW. 2) UV = UK; This is not correct because there is no sign of them being congruent to each other.3) JK = 2VW; We see that UKVW forms a rhombus. This means that parallel sides are equal. Thus; UK = VW.
Since UK is equal to UJ from the triangle, then;
2UK = JK
Since UK = VW, then; 2VW = JK. Thus, the statement is true.
4) UW = 12KL; This is not correct because UW = KV = KL/2 from the diagram.5) UV ║ JL; This statement is correct because from the diagram UV is a side of the parallelogram UVLW with UV parallel to WL since opposite sides of a parallelogram are equal.Read more at; https://brainly.com/question/7447576

Find y'' by implicit differentiation. 4x3 + 5y3 = 2
The value of implicit differentiation of y" of the 4x³ + 5y³ = 2 is [tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2} = 0\\[/tex].
To find y'', or the second derivative of y, by implicit differentiation, we'll differentiate both sides of the equation with respect to x, treating y as a function of x.
Step - 1:
Start by differentiating each term with respect to x using the chain rule:
Differentiating 4x³ with respect to x gives 12x².Differentiating 5y³ with respect to x requires the chain rule. We get 15y²(dy/dx).Since we're differentiating with respect to x, we need to multiply dy/dx by y' to indicate the derivative of y with respect to x.
Step - 2:
The right-hand side of the equation, 2, has a derivative of 0 since it is a constant.
Putting it all together, we have the equation:
[tex]12x^2 + 15y^2 \times \frac{dy}{dx} = 0.[/tex]
Now, to find y'', we differentiate this equation with respect to x, treating dy/dx as a function of x.
Differentiating 12x² with respect to x gives 24x.Differentiating 15y² × dy/dx with respect to x requires the product rule. We get [tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2}[/tex].Step - 3:
The right-hand side of the equation, 0, has a derivative of 0 since it is a constant.
Putting it all together, we have the equation:
[tex]30y \times \frac{dy}{dx} + 15y^2 \times \frac{d^2y}{dx^2} = 0\\[/tex]

To find y'' by implicit differentiation from the equation 4x^3 + 5y^3 = 2, differentiate both sides with respect to x, apply the chain and product rules appropriately and then solve for y''.
Explanation:To find the second derivative y'' by implicit differentiation for the equation 4x^3 + 5y^3 = 2, you follow these steps:
Differentiate both sides of the equation with respect to x to find the first derivative (y').Apply the chain rule to differentiate y terms, remembering to multiply by y' (dy/dx) because you are differentiating with respect to x.The differentiation of 4x^3 yields 12x^2, and the differentiation of 5y^3 using the chain rule gives you 15y^2*y'.You then set the derivative equal to 0, because the differential of 2 with respect to x is 0.To find the second derivative (y''), differentiate your expression for y' with respect to x again, applying the chain rule and product rule as necessary.This process will provide you with the value of y''.

Final answer:
To find the total cost of a jacket with sales tax, you can either use the given expression or calculate the sales tax separately and add it to the original price.
Explanation:
To find the total cost of a jacket with a sales tax, you can use the expression 55.80 + 0.027(55.80) as mentioned in the question.
Another way to find the total cost is to calculate the sales tax first and then add it to the original price of the jacket. To do this, you need to multiply the original price of the jacket by the sales tax rate (2.7% or 0.027) and then add the result to the original price: 55.80 + (0.027 * 55.80).

If you have 256 data points, how many classes (bins) would sturges' rule suggest
Final answer:
Sturges' rule suggests using 9 classes or bins for 256 data points.
Explanation:
Sturges' rule is a method for determining the number of classes or bins required for a histogram. According to Sturges' rule, the formula to calculate the number of classes is:
K = 1 + log2(n)
Where K is the number of classes and n is the number of data points. In this case, since you have 256 data points, the number of classes suggested by Sturges' rule would be:
K = 1 + log2(256)
K = 1 + log2(28)
K = 1 + 8
K = 9
Therefore, Sturges' rule would suggest using 9 classes or bins for the histogram.
