A random number generator is used to choose a real number between 0 and 100. The random variable x is the number chosen.
The probability that the computer generates a number between 1 and 4 is 4/11.
Since X has a uniform distribution, the probability of generating any number between 0 and 10 is equally likely. Therefore, the probability of generating a number between 1 and 4 is the same as the probability of generating a number between 0 and 4 minus the probability of generating 0
P(1 ≤ X ≤ 4) = P(X ≤ 4) - P(X = 0)
Since X has a uniform distribution, the probability of generating any specific number is 1/11. Therefore
P(X ≤ 4) = (4 + 1)/11 = 5/11
and
P(X = 0) = 1/11
So,
P(1 ≤ X ≤ 4) = (5/11) - (1/11) = 4/11

Find the area of a semicircle whose diameter is 28cm
Answer:
The area of a semicircle with diameter 28 cm is 98π cm², or 307.88 cm² to the nearest tenth.
Step-by-step explanation:
A semicircle is a two-dimensional shape that is exactly half of a circle.
The area of a circle is given by the formula:
[tex]\sf A=\pi r^2[/tex]
where A is the area of the circle, and r is the radius of the circle.
The diameter of a circle is twice its radius.
Given the diameter of the semicircle is 28 cm, the radius is:
[tex]\sf r = \dfrac{28}{2} = 14 \; cm[/tex]
Substituting this into the formula for the area of a circle, we get:
[tex]\sf A = \pi(14)^2[/tex]
[tex]\sf A = 196 \pi[/tex]
Finally, divide this by two to get the area of the semicircle:
[tex]\sf Area\;of\;semicircle = \dfrac{1}{2} \cdot 196 \pi[/tex]
[tex]\sf Area\;of\;semicircle = 98 \pi\; cm^2[/tex]
So the area of a semicircle with diameter 28 cm is 98π cm², or 307.88 cm² to the nearest tenth.

An animator uses green tiles to design a pattern that grows each second, as shown in this diagram. Use the drop-down menus to build functions that describe how the pattern is changing.
The function of tiles with no empty spaces is n(t) = t² + 2t, the function of tiles removed to create empty spaces is r(t) = t.
The function of tiles with no empty spacesWe have a sequence of tiles represented by the numbers 3, 8, and 15.
This sequence can be described as a quadratic sequence, which can be expressed using the formula
n(t) = at² + bt + c.
By substituting the values of the first three terms into this formula, we can find the values of a, b, and c.
a + b + c = 3
4a + 2b + c = 8
9a + 3b + c = 15
These values can also be determined by graphing the sequence. In this case, a = 1, b = 2, and c = 0.
Therefore, the quadratic sequence can be written as n(t) = t² + 2t.
The function of tiles removed to create empty spacesThe given sequence of tiles can be represented as a linear sequence in which the current term is equal to the number of spaces.
Therefore, the function r(t) can be defined as r(t) = t.
The function of tiles usedThe given equation is expressed as:

In a small town 50% of 2 story homes own computers and 35% of one story homes own computers. In dawn's neighborhood 75% of homes are 2 story. What is the probability that a two story home in dawn's neighborhood owns a computer
To solve this problem, we can use Bayes' theorem. Let's define:
- A: two story home
- B: owning a computer
We want to find the probability of B given A, which we can write as P(B|A). Using Bayes' theorem, we have:
P(B|A) = P(A|B) * P(B) / P(A)
We know that 50% of two story homes own computers, so P(B) = 0.5. We also know that 75% of homes in Dawn's neighborhood are two story, so P(A) = 0.75.
To find P(A|B), we need to use the conditional probability formula:
P(A|B) = P(A and B) / P(B)
We don't have the probabilities for A and B happening together, but we know that:
P(A and B) = P(B|A) * P(A)
Substituting this into the conditional probability formula gives:
P(A|B) = (P(B|A) * P(A)) / P(B)
Putting all the values together, we get:
P(B|A) = (P(A|B) * P(B)) / P(A)
= ((P(B|A) * P(A)) / P(B)) * P(B) / P(A)
= (P(B and A) / P(B)) * P(B) / P(A)
= P(A and B) / P(B)
Substituting the values gives:
P(B|A) = (0.5 * 0.75) / 0.5
= 0.75
Therefore, the probability that a two story home in Dawn's neighborhood owns a computer is 0.75.
The sum of three numbers is 70 . The third number is 2 times the first. The first number is 6 less than the second. What are the numbers?
Answer:
16, 22, and 32.
Step-by-step explanation:
Set up a system of equations to represent the situation with 3 unknown.
x + y + z = 70
z = 2x
x = y - 6 → y = x + 6
The second two equations are the y and z in terms of x, so substitute both into the first equation.
x + (x + 6) + 2x = 70
4x + 6 = 70
4x = 64
x = 16
Use this number to calculate the value of the other unknowns.
y = x + 6
y = 16 + 6
y = 22
Calculate z.
z = 2x
z = 2(16)
z = 32
So, the three numbers are 16, 22, and 32.
if the sum of a number and eight is doubled, the result is seven less than the number. Find the number.
Answer:
Step-by-step explanation:
Let's call the number we're looking for "x".
The problem tells us that "if the sum of a number and eight is doubled, the result is seven less than the number", which can be translated into an equation:
2(x+8) = x-7
Now let's solve for x:
2x + 16 = x - 7
2x - x = -7 - 16
x = -23
Therefore, the number we're looking for is -23.

What is the limit of (n!)^(1/n) as n approaches infinity?
Note: n! means n factorial, which is the product of all positive integers up to n.
Answer:
Step-by-step explanation:
To find the limit of (n!)^(1/n) as n approaches infinity, we can use the Stirling's approximation for n!, which is:
n! ≈ (n/e)^n √(2πn)
where e is the mathematical constant e ≈ 2.71828, and π is the mathematical constant pi ≈ 3.14159.
Using this approximation, we can rewrite (n!)^(1/n) as:
(n!)^(1/n) = [(n/e)^n √(2πn)]^(1/n) = (n/e)^(n/n) [√(2πn)]^(1/n)
Taking the limit as n approaches infinity, we have:
lim (n!)^(1/n) = lim (n/e)^(n/n) [√(2πn)]^(1/n)
Using the fact that lim a^(1/n) = 1 as n approaches infinity for any constant a > 0, we can simplify the second term as:
lim [√(2πn)]^(1/n) = 1
For the first term, we can rewrite (n/e)^(n/n) as [1/(e^(1/n))]^n and use the fact that lim a^n = 1 as n approaches infinity for any constant 0 < a < 1. Thus, we have:
lim (n/e)^(n/n) = lim [1/(e^(1/n))]^n = 1
Therefore, combining the two terms, we have:
lim (n!)^(1/n) = lim (n/e)^(n/n) [√(2πn)]^(1/n) = 1 x 1 = 1
Hence, the limit of (n!)^(1/n) as n approaches infinity is 1.

find a linear homogeneous constant-coefficient differential equation with the general solution that has the form
The linear homogeneous constant-coefficient equation is y'' - 4y' + 2y = 0
A linear homogeneous constant-coefficient equation is of the form:
ay'' + by' + cy = 0
where a, b, and c are constants, and y is a function of x. The general solution of this equation can be written as:
[tex]y(x) = c_1e^{(r_1x)} + c_2e^{(r_2x)}[/tex]
where r₁ and r₂ are the roots of the characteristic equation:
ar² + br + c = 0
In our case, the general solution is given as:
y(x) = [tex]Ae^{2x}[/tex] + Bcos(2x) + Csin(2x)
To find the linear homogeneous constant-coefficient equation that has this general solution, we need to first write the general solution in the form:
[tex]y(x) = c_1e^{(r_1x)} + c_2e^{(r_2x)}[/tex]
where r₁ and r₂ are the roots of the characteristic equation. Comparing this form with the given general solution, we see that r₁ = 2, r₂ = 2i, and r3 = -2i.
Therefore, the characteristic equation is:
a(r-2)(r-2i)(r+2i) = 0
Expanding this equation, we get:
a(r³ - 2r²i - 2ri² + 4r² + 8i²r - 8i) = 0
Simplifying and grouping the real and imaginary terms, we get:
a(r³ - 4r) + 2a(r² + 4) = 0
Dividing by a, we get:
r³ - 4r + 2(r² + 4) = y'' - 4y' + 2y = 0

Complete Question:
Find a linear homogeneous constant-coefficient equation with the given general solution
y(x)=Ae²ˣ+Bcos(2x)+Csin(2x)
Bria is a customer who would like to display her collection of soap carvings on top of her bookcase. The collection needs an area of 300 square inches. What should b equal for the top of the bookcase to have the correct area? Round your answer to the nearest tenth of an inch. (1 point)
help me pls D;
The length of the top of the bookcase is 20 inches, the width should be 15 inches to have the correct area.
How to find the dimensions of rectangle?Since the area of the soap carvings is 300 square inches, we want the top of the bookcase to have the same area. Let's assume the length of the top of the bookcase is "l" and the width is "b". Then we have:
Area of top of bookcase = lb
We want this area to be equal to 300 square inches. Therefore, we can write:
lb = 300
We are solving for "b", so we can rearrange this equation to solve for "b":
b = 300/l
Since we don't know the value of "l", we can't solve for "b" exactly. However, we can approximate it by assuming a value for "l". Let's say we assume that "l" is 20 inches. Then we can calculate "b" as follows:
b = 300/20 = 15
So if the length of the top of the bookcase is 20 inches, the width should be 15 inches to have the correct area.

According to the Venn diagram the value of [tex]n(A ^ C \cap B ^ C) = {3}[/tex] so the number of elements in that set is 1.
What is Venn diagram ?
A Venn diagram is a diagram that shows all possible logical relations between a finite collection of different sets. It is usually represented as a rectangle or a circle for each set and the overlapping areas between them, showing the common elements that belong to more than one set. Venn diagrams are widely used in mathematics, logic, statistics, and computer science to visualize the relationships between different sets and help solve problems related to set theory.
According to the question:
To solve this problem, we first need to understand the notation used.
n(A) denotes the set A and the numbers within the braces {} indicate the elements in set A. For example, n(A)={7,4,3,9} means that the set A contains 7, 4, 3, and 9.
n(AnB) denotes the intersection of sets A and B, i.e., the elements that are common to both A and B. For example, n(AnB)={4,3} means that the sets A and B have 4 and 3 in common.
^ denotes intersection of sets
cap denotes the intersection of sets
Now, we need to find the elements that are common to sets A and C, and sets B and C. We can do this by taking the intersection of A and C, and the intersection of B and C, and then taking the intersection of the two resulting sets.
[tex]n(A ^ C) = n(A \cap C) = {3,9}[/tex]
[tex]n(B ^ C) = n(B\cap C) = {3,5}[/tex]
Now, we take the intersection of [tex]n(A ^ C)[/tex] and [tex]n(B ^ C)[/tex]:
[tex]n(A ^ C \cap B ^ C) = {3}[/tex]
Therefore, the answer is 1.
