Answer:8s^3 , 27s^3 , n^3s^
Step-by-step explanation:
As we know that
Volume of the cube = side × side × side
let us assume that one side is s
side = 2s
Then,
Volume = 2s ×2s×2s
=8s^3
side =3s
Then,
Volume= 3s×3s×3s
=27s^3
side =ns
Then,
Volume= ns×ns×ns
=n^3 s^3
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.23 and event B occurs with probability 0.21.
a. Compute the probability that A occurs but B does not occur.
b. Compute the probability that either A occurs without B occurring or B occurs without A occurring.
Using it's concept, the probabilities for this problem are given as follows:
a) A occurs and B does not: 0.1817 = 18.17%.
b) Either occurs: 0.3434 = 34.34%.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
In the context of this problem, we have two mutually exclusive events, meaning that they cannot happen together.
For item a, we have that:
The probability of A occurring is 0.23.The probability of B not occurring is of 1 - 0.21 = 0.79.The events are mutually exclusive, hence we can multiply the probabilities as follows:
p = 0.23 x 0.79 = 0.1817 = 18.17%.
For item b, we add the probability in item with the probability of B occurring and A not, found as follows:
The probability of B occurring is 0.21.The probability of A not occurring is of 1 - 0.23 = 0.77.Hence:
p = 0.1817 + 0.21 x 0.77 = 0.3434 = 34.34%.

4. Write an equation of the line that passes through (1,3) and has a slope of 5/4
5. Write two equivalent equations for a line with x-intercept (3,0) and y-intercept (0, 2).
The equation of the first line is y = -1/3x - 4, while the equivalent equations of the second line are y = -2/3(x - 3) and y = -2/3x + 2
How to determine the equation of the line?The given parameters are
Slope, m = 5/4
Point, (x1, y1) = (1, 3)
A linear equation is represented as
y = m(x - x1) + y1
So, we have
y = 5/4(x - 1) + 3
This gives
y = 5/4x + 7/4
Hence. the linear equation is y = 5/4x + 7/4
The equivalent equationsHere, we have
(x, y) = (3, 0) and (0, 2)
A linear equation is represented as
y = m(x - x1) + y1
Where
m = (y2 - y1)/(x2 - x1)
So, we have
m = (2 - 0)/(0 - 3)
m = -2/3
So, we have
y = -2/3(x - 3)
The above equation can be rewritten as
y = -2/3x + 2
Hence, the equations are y = -2/3(x - 3) and y = -2/3x + 2

The side length of the square that provides a counterexample to the statement square units in the area of a square is greater than or equal to the number of units in the perimeter is 2 Units.
What is a square?A square is a kind of a 2D figure in which all the sides are equal.
We know that the absolute perimeter of a square is the sum of the lengths of all the total sides and as we see the area of a square is (side)².
Assuming that the whole square has four units completed for each side.
The square's circumference can be calculated as is 4 sides plus 4 fours, or as seen as 16 units.
Now the area of the square will be calculated as (4) ² = 16 sq units.
Now assuming that the total side length of the square about is 2 units.
The square's perimeter is calculated as (24) = 8 units, while its total area is calculated as (22) = 4 units.
∴ 2 units make up the side length that serves as a counterexample.
Basically, herein we have to determine the absolute numbers that when are multiplied by 4 are seen to be greater than it's square such numbers are 1, 2, 3.

two carts, a and b, are connected by a rope 39 ft long that passes over a pulley p. the point q is on the floor 12 ft directly beneath p and between the carts. cart a is being pulled away from q at a speed of 2 ft/s. how fast (in ft/s) is cart b moving toward q at the instant when cart a is 5 ft from q? (round your answer to two decimal places.)
The velocity of the cart b is found as 20/23 ft/s over the pulley.
What is defined as the rate of change?The momentum of a variable is represented by the rate of change, which is used to mathematically define the percentage change in value over such a defined period of time.For the given data in the question.
q's velocity is 2 feet per second.
Rope length is 39 feet.
Assume x is the distance between A and Q. (refer the image).
Assume y is the distance between Q and B. (refer the image).
As a result of the image,
x² + 12² = L²
Now, with respect to time t, differentiate the above equation.
2x(dx/dt) + 0 = 2L.(dL/dt)
For x = 5 ft and L = 13 ft
dL/dt = (5×2)/13 = 10/13
In the case of B,
y² + 12² = (39 - L)² ; from diagram.
Differentiating now,
2y(dy/dt) + 0 = -2(39 - L).(dL/dt)
At x = 5 ft and y = 23 ft.
dy/dy = -20/23
(A negative sign indicates the opposite direction)
Thus, the velocity of cart b is found as 20/23 ft/s.

The. median, range, and mode for the following numbers:8,7,12,7,11,10,7,12
Answer:
median = 9
range = 5
mode = 7
Step-by-step explanation:
median = 9 is in the middle of 10 and 8
range = 12 - 7
mode = there are 3 7s
Mode : the quantity that appears the most in a sequence
Because 7 is the number that appears the most ( 3 times ), it is the mode.
Range : the difference between the largest number and the smallest number
In this case, 12 is the biggest and 7 is the smallest -> Range = 5.
Median : the "middle number" (for example, if the sequence has 7 numbers, the 4th number will be the median. if the sequence has 8 numbers, the median will be the average of the 4th and 5th number, and of course from increasing order.)
There are 8 numbers in the sequence, from lowest to highest : 7,7,7,8,10,11,12,12.
So, the median = (8+10)/2 = 9.

Gabi is correct to say that the rectangle will be enlarged when it will be dilated by a scale factor of 3/2.
What does the scale factor determine?The image's size will depend on the scale factor, which is used to dilate a mathematical entity (compared to the original object).An expansion happens when the scaling factor's absolute value exceeds one.Compression happens when the scale factor's absolute value falls below one.When the scale factor's absolute value is 1, neither expansion nor compression takes place.As it is given that the rectangle BCDE is dilated by the scale factor of 3/2 which is more than 1, so the rectangle will expand or enlarge.
