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.

Step-by-step explanation:
Your bowl contains 8 red balls, and 9 blue balls, and you draw 4 balls. in how many ways can the selection be made so that at least one of each color is drawn?
In 2156 ways the selection be made so that at least one of each color is drawn?
The question is asking for the number of ways to select balls from a bowl containing 8 red balls and 9 blue balls if 4 balls are drawn and at least one of each color is drawn.
To solve this, we must consider the different combinations of red and blue balls that meet the requirement.
Calculate the total possible outcomes: 17C4 = 2380
Calculate the outcomes where all balls of one color are drawn: 9C4 + 8C4 = 224
Subtract the outcomes where only one color is drawn from the total: 2380 - 224 = 2156 ways

Which statements must be true?
Select each correct answer.
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

A cube has a volume of 729 cubic centimeters. What can be concluded about the cube? Check all that apply. Recall the formula mr021-1.jpg. The side length, s, can be found using the equation mr021-2.jpg This is a perfect cube. The side length is 243 centimeters. The side length is 9 centimeters. Taking the cube root of the volume will determine the side length. If you multiply the volume by three, you can determine the side length.
Answer:
This is a perfect cube
The side length is [tex]9[/tex] centimeters
Taking the cube root of the volume will determine the side length
Step-by-step explanation:
we know that
The volume of a cube is equal to
[tex]V=s^{3}[/tex]
where
s is the length side of the cube
In this problem we have
[tex]V=729\ cm^{3}[/tex]
Solve for s-------> that means isolate the variable s
Find the length side of the cube s
[tex]s=\sqrt[3]{V}[/tex]
substitute the value of V
[tex]s=\sqrt[3]{729}=9\ cm[/tex] --------> a perfect cube
therefore
Statements
This is a perfect cube--------> Is true
The side length is [tex]9[/tex] centimeters -------> Is true
Taking the cube root of the volume will determine the side length ------> Is true
The side length of the cube is 9cm³ showing that the cube is a perfect cube
Volume of the cubeThe formula for calculating the volume of a cube is expressed as:
V = s³
where:
s is the side length of the cube
Given the following
V = 729cm³
Substitute the given parameters into the formula
729 = s³
s³ = 729
s = 9cm
Hence the side length of the cube is 9cm³ showing that the cube is a perfect cube

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''.
