The probability of P(X ≤ 2) is 0.0135
We have the information available from the question:
Binomial variable is X
the value of n = 5
and, the value of p = 0.4
We are given to compute the probability P(X [tex]\leq[/tex] 2) and round the answer to five decimal places.
The binomial distribution formula is given by:
[tex]P(X)=nCx(p)^x(1-q)^n^-^x[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)!x!}[/tex]
We have to find the probability:
P(X [tex]\leq[/tex] 2) = P(X=1) + P(X=2)
P(X = 1) = [tex]5C1(0.4)^1(1-0.4)^5^-^1[/tex] = 0.0026
P(X= 2) =[tex]5C2(0.4)^2(1-0.4)^5^-^2[/tex] = 0.0109
P(X [tex]\leq[/tex] 2) = P(X=1) + P(X=2)
P(X [tex]\leq[/tex] 2) = 0.0026 + 0.0109
P(X [tex]\leq[/tex] 2) = 0.0135

build a binary search tree for the words banana, peach, apple, pear, coconut, mango, and papaya using alphabetical order.
To build a binary search tree using alphabetical order for the given words, we start with an empty tree and insert each word in the appropriate position based on its alphabetical order.
Here's the step-by-step process:
Start with an empty tree.
Insert the first word, "banana," as the root of the tree.
Insert the second word, "peach," comparing it to the root. Since it comes after "banana," it becomes the right child of the root.
Insert the third word, "apple." Comparing it to the root, it comes before "banana," so we traverse to the left child of the root. Since the left child is empty, "apple" becomes the left child of "banana."
Insert the fourth word, "pear." Comparing it to the root, it comes after "banana," so we traverse to the right child. Comparing it to "peach," it comes before "peach," so we traverse to the left child of "peach." Since the left child is empty, "pear" becomes the left child of "peach."
Insert the fifth word, "coconut." Comparing it to the root, it comes before "banana," so we traverse to the left child. Comparing it to "apple," it comes after "apple," so we traverse to the right child. Comparing it to "pear," it comes before "pear," so we traverse to the left child of "pear." Since the left child is empty, "coconut" becomes the left child of "pear."
Insert the sixth word, "mango." Comparing it to the root, it comes after "banana," so we traverse to the right child. Comparing it to "peach," it comes before "peach," so we traverse to the left child. Comparing it to "pear," it comes after "pear," so we traverse to the right child. Comparing it to "coconut," it comes after "coconut," so we traverse to the right child. Since the right child is empty, "mango" becomes the right child of "coconut."
Insert the seventh word, "papaya." Comparing it to the root, it comes after "banana," so we traverse to the right child. Comparing it to "peach," it comes after "peach," so we traverse to the right child. Comparing it to "pear," it comes after "pear," so we traverse to the right child. Comparing it to "coconut," it comes after "coconut," so we traverse to the right child. Comparing it to "mango," it comes after "mango," so we traverse to the right child. Since the right child is empty, "papaya" becomes the right child of "mango."
The resulting binary search tree will look like this:
banana
/ \
apple peach
\ \
pear papaya
/
coconut
\
mango
Note: The tree might have different structures depending on the order of insertion, as long as it maintains the binary search tree property.

Bryan is a waiter. He waits on a table of 4 whose bill comes to $110.31. If Bryan receives a 15% tip, approximately how much will he receive?
If Bryan receives a 15% tip, then he will receive an amount of approximately $16.55 as a tip.
In order to calculate the tip-amount, we need to multiply the total-bill by the tip percentage. In this case, the "bill-amount" is $110.31, and the tip percentage is 15%.
To find the tip amount, we can use the formula:
Tip amount = (Total bill) × (Tip percentage),
Simplifying further,
We get,
Tip amount = $110.31 × 0.15,
= $16.5465 (rounded to the nearest cent)
Therefore, Bryan will receive approximately $16.55 as a tip.

If angle A=320∘, what is the radian measure of A? Give your answer as an exact fraction in terms of π.
The radian measure of angle A is (16/9)π.
To convert degrees to radians, we use the conversion factor:
[tex]1\ degree = \pi /180\ radians[/tex]
Given that angle A is 320 degrees, we can calculate its radian measure as follows:
Angle A in radians = (320 degrees) * (π/180 radians/degree)
= (320π)/180 radians
= (16/9)π radians
Therefore, the radian measure of angle A is (16/9)π.

1. 38° 2. 65° 3. 52° 4. 72°
Answer:
3
Step-by-step explanation:
The closest angle to F in the triangle is 52 degrees.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that Right triangle EFG it is known that the side opposite of acute angle F has a length of 18 inches and the leg adjacent to F has a length of 14 inches.
We can use the tangent function to find the measure of angle F:
tan(F) = opposite/adjacent = 18/14
we can find the inverse tangent of this value:
F = tan⁻¹(18/14)
= tan⁻¹(1.28)
F= 52.15°
Hence, the closest angle to F in the triangle is 52 degrees.

Use the Laplace transform to solve the following initial value problems. 2 a) ' +5/- y = 0, (O) = -1/(0) = 3 b) +4+ 30) = -1. V(0) - 2
To solve the initial value problems using the Laplace transform, we can apply the Laplace transform to the given differential equations and initial conditions.
For the first problem, the Laplace transform of the differential equation is s^2Y(s) + 5sY(s) + 2Y(s) = 0. Solving for Y(s), we find Y(s) = -3/(s+1).
Taking the inverse Laplace transform, we obtain the solution y(t) = -3e^(-t). For the second problem, the Laplace transform of the differential equation is sY(s) + 4Y(s) + 3/(s+1) = -2. Solving for Y(s), we find Y(s) = (-2s - 1)/(s^2 + 4s + 3). Taking the inverse Laplace transform, we obtain the solution y(t) = (-2t - 1)e^(-t).
a) The Laplace transform of the given differential equation is:
s^2Y(s) + 5sY(s) + 2Y(s) = 0
Using the initial condition Y(0) = -1 and Y'(0) = 3, we can apply the initial value theorem to obtain:
Y(s) = -1/s + 3
Taking the inverse Laplace transform of Y(s), we find:
y(t) = -3e^(-t)
b) The Laplace transform of the given differential equation is:
sY(s) + 4Y(s) + 3/(s+1) = -2
Using the initial condition Y(0) = -1, we can apply the initial value theorem to obtain:
Y(s) = (-2s - 1)/(s^2 + 4s + 3)
Taking the inverse Laplace transform of Y(s), we find:
y(t) = (-2t - 1)e^(-t)

where S is the processor speed in MHz. Find the processor speed for which cost is at a
minimum. [4 marks]
Answer:
The speed is: 0.0142MHz
Step-by-step explanation:
Given
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
Required
The processor speed when the cost is at minimum
First, differentiate C(s) with respect to s
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
[tex]C'(s) = 2468s - 35[/tex]
The cost is at minimum when [tex]C'(s) = 0[/tex]
So, we have:
[tex]C' = 2468s - 35 = 0[/tex]
[tex]2468s - 35 = 0[/tex]

Some unsound arguments are valid. True or False?
The statement "Some unsound arguments are valid" is false.
The statement "Some unsound arguments are valid" is false.
A valid argument is a statement that follows the rules of logic.
An argument is known to be sound when it is valid and has true premises. When the premises of an argument are correct, the argument is considered sound. When an argument is valid, it follows logically from its premises, which are the statements that provide evidence or support for the argument's conclusion.
The unsound argument is the one that contains at least one false premise.
The sound argument is the one that contains only true premises and is valid (that is, follows logically from the premises).
If an argument is unsound, it can never be valid because it contains at least one false premise.
Therefore, the statement "Some unsound arguments are valid" is false.
