Answer:
a) 512cm³ b) 2 × 2 ×2
Step-by-step explanation:
A CUBE'S LENGTH WIDTH AND HEIGHT ARE EQUAL
a) Volume of a cube = length × width × height
as the length width and height are equal so it will be
8 × 8 × 8 = 512
b) Volume of a cube = length × width × height
as length, width and height are equal lets suppose the value of each of them will be = x
volume = x × x × x
vol = x³
8 = x³
∛8 = x
x = 2

What price do farmers get for their watermelon crops? in the third week of july, a random sample of 40 farming regions gave a sample mean of x bar = $6.88 per 100 pounds of watermelon. assume that is known to be $2.00 per 100 pounds.
Answers
We have given a sample size of n=40
Sample mean ¯x=$6.88 per 100 pounds
Population standard deviation= 1.96 per 100 pounds
First, we need to find the value of z α /2 =z (1−0.90/2)
Z (α/2) =z0.05
Z (α/2) =1.645
(a)The required 90% confidence interval is;
¯x ± margin of error
¯x ± z (α/2) * σ/sqrt 40
6.88 ± 1.645 * 1.96/sqrt 40
6.88±0.5097
(6.38,7.38)
Therefore, the lower limit is $6.38 per 100 pounds.
The upper limit is $7.38 per 100 pounds.
The margin of error is 0.50 per 100 pounds.
(b) to have the maximum of E, we use the formula;
n= (z (α/2)×σ/E) ^2
n= (1.645× (1.96/0.41)) ^2
n=61.84≈62
Therefore, the required farming region will be 62.

Exact Distance: [tex]\sqrt{130}[/tex] units

Explanation:
Use the distance formula to have the following steps
[tex](x_1,y_1) = (3,-2) \text{ and } (x_2, y_2) = (-4,7)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-(-4))^2 + (-2-7)^2}\\\\d = \sqrt{(3+4)^2 + (-2-7)^2}\\\\d = \sqrt{(7)^2 + (-9)^2}\\\\d = \sqrt{49 + 81}\\\\d = \sqrt{130}\\\\d \approx 11.4018\\\\[/tex]
The exact distance is [tex]\sqrt{130}[/tex] units

Why is it known as a node?
Node is the actual name in use. It was initially intended to be used as a web application, but the author changed the name to node after realizing it could be applied to a variety of situations.
Pipe standing wave resonances exhibit a number of intriguing characteristics. When sounding a resonance, the closed end of the pile must have a "node." An "anti-node" is required if a pipe's end is open.The lowest frequency resonance occurs in the case of a pipe that is closed at one end when there is just one node at the closed end and an anti-node at the other end. This sound has a wavelength that is four times as long as the pipe. This is referred to as a quarter-wave resonator.When a pipe is opened on both ends, the lowest frequency resonance has an anti-node at either end and a node in the center. A half-wave resonance is present here; The pipe is able to contain half of the wavelength. The frequency of this resonance will be twice that of the closed pipe if this pipe is the same length as the closed pipe.Learn more about node

A member of the junior varsity swim team will be elected as President. Each member is equally likely to be elected. The probability that a sophomore is elected is $3/2$ times the probability that a freshman is elected. Everyone on the junior varsity swim team is either a freshman or sophomore. What fraction of the swim team are sophomores?
Answers
Using the probability concept, it is found that 60% of the swim team are sophomores.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The sum of the probabilities of all outcomes of an event is of 1, hence:
P(freshman) + P(sophomore) = 1.
The probability that a sophomore is elected is $3/2$ times the probability that a freshman is elected, hence:
x + 3/2x = 1.
5/2x = 1
5x = 2
x = 0.4.
Thus:

The equation which could show the missing step in Tyler's solution to the equation as requested in the task content is; 10x + 8x = 36.
What is the solution that could show the missing step in Tyler's solution to the equation as requested in the task content?It follows from the task content that the missing step in the solution steps is to be determined.
Given an equation;
10x = -4(2x-9)
By distributing -4 on the right hand side, we have;
10x = -8x + 36
The next step which is therefore the missing step is;
Add 8x to both sides of the equation so that we have;
10x + 8x = 36
18x = 36
Divide both sides by 18, so that we have;
x = 2 as obtained in the task content.
Ultimately, the equation which could show the missing step in Tyler's solution to the equation as requested in the task content is; 10x + 8x = 36.

The denominator in the earnings per share formula is? a.preferred dividends. b.net income. c.number of preferred shared outstanding. d.number of common shares outstanding.
Answers
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share. The "per share" part necessitates further computation when the number of common shares changes in the middle of the year. The weighting of the per share part depends on how long each share number has been in circulation.How are basic earnings per share determined?
Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period. Preferred dividends should be removed from the net income because they are not available to common stockholders. Net income can also be broken down into "continuing operations" P&L and "total P&L".Learn more about Basic EPS

Given the inequality −6
Answers
The absolute value inequality is |x - 6| < 12 and the complete points are Midpoint = 6 and Distance = 12
How to complete the inequality?The inequality expression is given as
-6 < x < 18
The distance is calculated as:
Distance = |18 -(-6)|/2
Evaluate the difference
Distance = 12
The midpoint is calculated as:
Midpoint = 0.5 * (18 - 6)
Evaluate
Midpoint = 6
The absolute value inequality is represented as
|x - Midpoint| < Distance

The domain of the function is -∝ < x < ∝, the range of the function is -∝ < y < ∝, and the x-intercept of the function is (-1, 0)
How to identify the domain, range, and x-intercept of the function?The equation of the function is given as
g(x) = 4x + 4
The function g(x) is a linear function.
There is no restriction on the input values and output values of a linear function
This means that the domain and the range of a linear function are the set of all real numbers
Set g(x) to 0, to determine the x-intercept
So, we have
4x + 4 = 0
Divide through by 1
So, we have
x + 1 = 0
Evaluate the like terms

When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
