The number 0.54227406110177, is non- repeating and non- terminating, so, that is an irrational number.
We have to determine that the number 0.54227406110177, is rational or irrational.
There is infinite numbers of rationals or irrationals between two real numbers. Rational number is of form p/q where q≠0 and p and q are integers. For example 1/2 , 1/4 are rationals. To identify if a number is rational or not, check the following conditions :
It is expressed in the form of p/q, where q≠0.After simplification, the ratio p/q is represented in decimal form. the decimal expansion of an rational number is repeating and terminating.The numbers which are not rational numbers are called irrationals. Here, see the number 0.54227406110177, no repetition of numbers in decimal form and non- terminating. So, it not a rational number. Hence, it is an irrational.

for each positive integer n, what is the largest value of p such that zero is the most likely number of successes in n independent trials with success probability p?
The largest value of success probability p with zero as most likely number of success with n independent trials is equal to 1 / ( n + 1 ).
Probability of success is equal to p
Probability of failure is equal to ( 1 - p)
Number of trials is positive integer n
Condition for 'n' independent trials :
Zero is most likely number of success
⇒ P(0) ≥ P(1)
⇒ ⁿC₀ p⁰ ( 1 - p )ⁿ⁻⁰ ≥ ⁿC₁ p¹ ( 1 - p )ⁿ⁻¹
⇒ ( 1 - p )ⁿ ≥ np ( 1 - p )ⁿ⁻¹
⇒( 1 - p ) ≥ np
⇒ np + p ≤ 1
⇒ p ≤ 1 / ( n + 1 )
Largest value of p is equal to 1 / ( n + 1 ).
Therefore, the largest value of success probability p with n independent trials is equal to 1 / ( n + 1 ).

Express 20cm to 15m
to the lowest form
Answer:
Step-by-step explanation:
To convert 20 cm to meters, we divide by 100, because 1 meter = 100 centimeters.
So, 20 cm = 20/100 m = 0.2 m
To convert 0.2 m to meters in the lowest form, we divide by 15, because 1 meter = 15 units.
So, 0.2 m = 0.2/15 m = 0.013 m
So the final answer is 0.013 m.

A group of volunteers tagged and released 29 owls as part of a research project. Later, the researchers counted 902 owls, 11 of which had tags. To the nearest whole number, what is the best estimate for the owl population?
The best estimate for the owl population is 2,378.
The population of the owl can be estimated using the concept of proportion. Proportion refers to a mathematical comparison between two numbers. According to the concept, if two sets of given numbers are increasing or decreasing in the same ratio, hence the ratios are said to be directly proportional to each other.
Based on the provided information, 29 owls are tagged and released as part of a research project. Assume that the total number of owl populations is x. At the later time, researchers counted 902 owls and found the 11 were tag. Hence, there are 18 tagged owls which are not accounted for. Assuming that the proportional of tagged owls to number of owls counted applies to the remaining population, the total number of owls can be best estimated as:

What is the midpoint of the segment shown below O A (-7/2, 3/2) O B. (-7,3) O c. (-7/2, 3) O D. (-7,3/2)
Answer:
B.
Step-by-step explanation:
The midpoint of a line segment is found by taking the average of the x-coordinates and the y-coordinates of the endpoints of the segment.
The midpoint of segment AB can be found as follows:
Midpoint of AB = ((-7/2 + -7)/2, (3/2 + 3)/2) = (-7, 3)
Since the midpoint of AB is the same as point B, we can conclude that the midpoint of segment AB is (-7, 3).
height of a cuboid is three-fourths of its length,breadth is 4 cm and total surface area is 608,finds the length and height of the cuboid.
Height of a cuboid is three-fourths of its length,breadth is 4 cm and total surface area is 608.
the length of the cuboid is 24 cm and its height is 18 cm.
Let us denote the length of the cuboid as "l" and the height of the cuboid as "h".
Based on the facts provided, we may conclude:
h = (3/4)l
Furthermore, the total surface area is 608, which may be computed as follows:
608 = 2(lb + bh + lh)
Extending the formula and changing the value of h:
608 = 2(lb + bh + l(3/4)l)
2(lb + 4h + (3/4)l^2) = 608
Now that we have the equation, we can solve for l by substituting the values of b (breadth) and h (height):
2(4l + 4h + (3/4)l^2) = 608
8l + 8h + (3/2)l^2 = 304
(3/2)l^2 + 8l + 8h = 304
We can now solve for l using the quadratic formula:
l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 8h))) / (2 * (3/2))
Because h = (3/4)l, we may simplify by substituting this formula for h:
l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 3l))) / (2 * (3/2))
Expanding the square root:
l = (-8 ± √(64 + 12l)) / 3
When we solve for l, we get:
l = 24
Finally, for h, substitute the value of l into the equation:
h = (3/4) * 24 = 18

Can someone please explain how to group terms in maths (I'm really struggling here )
Answer:
Step-by-step explanation:
Grouping terms in mathematics refers to the process of combining like terms, which are terms that have the same variable raised to the same power.
For example, consider the expression 2x + 3x. The terms 2x and 3x are like terms because they both have the variable x, so they can be grouped together:
2x + 3x = (2 + 3)x = 5x
When grouping terms, it's important to simplify each group of like terms before combining them. For example, consider the expression 2x^2 + 3x^2 + 4x^3. The terms 2x^2 and 3x^2 are like terms because they both have x raised to the power of 2, but they are not like terms with 4x^3 because it has x raised to a different power. To group the terms correctly, we simplify each group of like terms first:
2x^2 + 3x^2 = (2 + 3)x^2 = 5x^2
2x^2 + 3x^2 + 4x^3 = 5x^2 + 4x^3
Once all like terms are grouped and simplified, the expression can be simplified further by combining the groups of like terms:
5x^2 + 4x^3 = 5x^2 + 4x^3
This final expression is the simplified form of the original expression.

)
. Find a sinusoidal function that matches the given graph. If needed, you can enter
π
=3.1416... as 'pi' in your answer, otherwise use at least 3 decimal digits.
Answer:
Step-by-step explanation:
To find a sinusoidal function that matches the given graph, we need to find the amplitude (A), period (T), phase shift (h), and vertical shift (k) of the function.
Since the graph goes through the points (-9,0) and (5,0), we know that the maximum value of the function is located at the average of the x-values, which is -2, and that the minimum value of the function is located at the average of the x-values, which is (9+5)/2 = 7. The amplitude of the function can be found by taking half the difference of the maximum and minimum y-values, which is 0 - (-2)/2 = 1.
The period of the function can be found by taking the difference of the x-values of two consecutive maxima or minima, which is 5-(-9) = 14.
The phase shift can be found by noting the horizontal shift of the graph from its standard form, which is usually given by the equation y = A sin(x). In this case, the graph is shifted 2 units to the right, so the phase shift is 2.
The vertical shift can be found by noting the location of the midline of the graph, which is half way between the maximum and minimum y-values. In this case, the midline is at y = -1.
Putting all these values together, we can write a sinusoidal function that matches the given graph as:
f(x) = 1 sin(x + 2π/14) - 1
This function has amplitude 1, period 14, phase shift 2π/14 to the right, and a vertical shift of -1 down.

The rectangular floor of a classroom is 30 feet in length and 33 feet in width. A scale drawing of the floor has a length of 10 inches. What is the perimeter, in inches, of the floor in the scale drawing?
The perimeter of the floor in the scale drawing is 42 inches.
To find the scale factor, we can use the length of the room in the original and the scaled drawing:
scale factor = length in scale drawing / length in original = 10 inches / 30 feet
Since 1 foot = 12 inches, we can convert the length of the room to inches:
30 feet * 12 = 360 inches
So, the scale factor is 10 inches / 360 inches = 1/36.
To find the length of the room in the scaled drawing, we can use the scale factor:
length in scale drawing = scale factor * length in original = (1/36) * 360 inches = 10 inches
And the width in the scaled drawing would be:
width in scale drawing = scale factor * width in original = (1/36) * 33 feet * 12 inches/foot = (1/36) * 396 inches = 11 inches
Finally, to find the perimeter of the room in the scaled drawing, we add up the lengths of all four sides:
perimeter = 2 * (length in scale drawing) + 2 * (width in scale drawing) = 2 * 10 inches + 2 * 11 inches = 20 inches + 22 inches = 42 inches.
