Answer:
62.5%
Step-by-step explanation:
In this case we have the information we need to calculate the percentage because they give us the necessary experimental probability, we only have to pass the probability to its percentage form.
We know that probability can be converted to a percentage by multiplying the value of probability by 100, like so:
5/8 * 100 = 62.5
In other words, the probability that it will arrive at that time is 62.5%
A pencil holder shaped like a triangular prism is shown in the picture the height of the pencil holder is 12 cm,and the volume of the pencil holder is 216 cm.what is the area of the base of the pencil holder in square centimeters
The area of the base of the triangular prism-shaped pencil holder is 18 square centimeters, calculated by dividing the given volume of 216 cm³ by the height of 12 cm.
The question asks for the area of the base of a pencil holder with a given volume and height, shaped like a triangular prism. To find the area of the base of the pencil holder, we can use the formula for the volume of a prism: Volume = Base Area imes Height. Since the volume and height are given, we can rearrange the formula to solve for the Base Area as follows:
Base Area = Volume / Height
Plugging in the values given:
Base Area = 216 cm³ / 12 cm
Base Area = 18 cm²
Therefore, the area of the base of the pencil holder is 18 square centimeters.
Cylinder A has a base of 3 and height of 3 cylinder be has the base of 2 and the height of 4. What is the ratio of the volume of cylinder A to the volume of cylinder B?
Answer:
1.6875
Step-by-step explanation:
For cylinder A, the base = diameter = 3, the height of the base is 3.
The radius of cylinder A (r) = diameter / 2 = 3/2 = 1.5
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1.5² × 3 = 6.75π
For cylinder B, the base = diameter = 2, the height of the base is 4.
The radius of cylinder B (r) = diameter / 2 = 2/2 = 1
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1² × 4 = 4π
The ratio of the volume of cylinder A to the volume of cylinder B = volume of cylinder A / volume of cylinder B = 6.75π / 4π = 1.6875

Which statement is correct about the system of linear equations graphed below? On a coordinate plane, a line with negative slope goes through (0, 3) and (4, 2). A line with positive slope goes through (0, negative 4) and (4, negative 2). The system of equations has one solution because the lines will eventually intersect. The system of equations has one solution because the lines will never intersect. The system of equations does not have one solution because the lines will eventually intersect. The system of equations does not have one solution because the lines will never intersect.
Answer:
the answer is A. The system of equations has one solution because the lines will eventually intersect
Step-by-step explanation: because as the line goes on it will intercect once and if it has only one point of intercect its one solution
The system of equations has one solution because the lines will eventually intersect.
Which statement is true?
We know that for a system of equations, the solutions are the points where the graphs of the equations do intercept.
Also, remember that two lines always intercept if they have different slopes (parallel lines have the same slope and different y-intercept).
In this particular case, we know that one line has a negative slope and the other has a positive slope, so the lines are not parallel. This means that the lines will intercept, so the system has one solution.
With that in mind, the correct statement is "The system of equations has one solution because the lines will eventually intersect."

What is the inverse of f(x)= 1/5 x
Is it an inverse function?
The inverse of the function f(x) = 1/5x is found by switching the roles of y and x, then solving for y. This results in the inverse function f^-1(x) = 5x, which undoes the effect of the original function.
Explanation:The inverse of a function, in this case f(x) = 1/5x, is the function that will reverse the effect of the original function. In this case, to find the inverse function of f(x), you swap the roles of y and x in the original function and solve for y.
So, f(x) = 1/5x becomes x = 1/5y. Multiply both sides by 5 to get rid of the denominator on the y-side, which results in 5x = y. Thus, the inverse function is f^-1(x) = 5x.
It's indeed an inverse function as it reverses the effect of the initial function f(x).

Complete question:
A veterinarian surveys her clients and finds that 32 percent of the households have dogs, 25 percent have cats, and 11 percent have both dogs and cats. Let event C be choosing a client who has cats and let event D be choosing a client who has dogs. Which statements are true? Check all that apply.
1. P(C | D) = 0.78
2. P(D | C) = 0.44
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
5. P(C | D) = P(D | C)
Answer:
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
Step-by-step explanation:
Clients that have Cats = P(C) = 25% = 0.25
Clients that have Dogs = P(D) = 32% = 0.32
The number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11
Sets of data in mathematics are governed by laws which include Distributive law, Commutative law, Associative law, Identity law e.t.c.
The commutative law of sets states that :
A ∩ B = B ∩ A
A ∪ B = B ∪ A
Therefore, based on the commutative law of sets, Option 4 " P(C ∩ D) = P(D ∩ C) " is correct.
Since we are told in the question above that the number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11 and based on the commutative law that says
P(C ∩ D) = P(D ∩ C)
Therefore, Option 3 " P(C ∩ D) = 0.11"
is correct as well.

r=1 ft
Give the exact answer in simplest form.
feet
Final answer:
The diameter of a circle with a radius of 1 foot is 2 feet.
Explanation:
The radius of a circle is half the diameter. So, if the radius (r) of a circle is given as 1 foot, the diameter (d) is simply twice the radius. Therefore, the diameter is:
d = 2 × r
d = 2 × 1 ft
d = 2 ft
Hence, the diameter of the circle is 2 feet.

Suppose a culture of bacteria begins with 5000 cells and dies by 30% each year. Write an equation that represents this situation.
Answer:
[Tex]A(t)=5000(0.7)^t[/tex]
Step-by-step explanation:
The problem presented is one in which the population of the bacteria depreciates by a decay factor r every year.
Since it is a decay problem, we use the model:
[Tex]A(t)=P(1-r)^t[/tex]
Initial Population, P=5000
Decay Rate,r=30%=0.3
t=time interval
Therefore, the equation that represents this situation is:
[Tex]A(t)=5000(1-0.3)^t[/tex]
[Tex]A(t)=5000(0.7)^t[/tex]
The equation that represents this situation is y = 5000(0.7)ˣ
An exponential decay is given by:
y = abˣ
where a is the initial value of y, b is the rate of decay and y, x are variables.
Since the culture begins with 5000 cells, hence a = 5000. The cells die by 30% each year, hence b = 100% - 30% = 0.7
The equation is: y = 5000(0.7)ˣ
Therefore the equation that represents this situation is y = 5000(0.7)ˣ

Answer:
42 x - 24 x n - i = 0
Step-by-step explanation:
Expand the following:
6 x (7 - 4 n) = i
6 x (7 - 4 n) = 6 x×7 + 6 x (-4 n):
6×7 x - 4×6 x n = i
6×7 = 42:
42 x - 4×6 x n = i
6 (-4) = -24:
42 x + -24 x n = i
Subtract i from both sides of 42 x - 24 x n = i:
42 x - 24 x n - i = i - i
-i + i = 0:
Answer: 42 x - 24 x n - i = 0

A rectangular gardens length is 6 feet longer than it’s width. if the perimeter can be represented by P(x)= 4x + 12.
What is the width and length of the garden if the perimeter is 32 ft?
Answer:
The width is 5 and the length is 11
Step-by-step explanation:
The formula for perimeter is
P = 2(l+w)
We know the perimeter is 32
32 = 2 (l+w)
Divide each side by 2
32/2 = 2(l+w)
16 = l+w
We know the length is 6 longer than the width
l = w+6
16 = w+6+w
Combine like terms
16 = 2w+6
Subtract 6 from each side
16-6 = 2w+6-6
10 = 2w
Divide by 2
10/2 = 2w/2
5 =w
The length is
l = w+6
5+6 = 11
