Answer: 108 degrees.
Step-by-step explanation:
I think this is how you solve it:
A circle has a total of 360 degrees.
Having 5 equally placed sensors with a certain detection angle means that the sensors form a regular pentagon.
Finding the measure of the interior angles of a regular pentagon can be found using the formula
(180(n-2))/n, with n being the number of vertices of the polygon.
180(5-2)/5 ; 180(3)/5 ; 540/5 = 108
I think this means the detection angle is 108 degrees. Hope this helps!

Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.30 and P(B) =0.40.
What is P(AAssume that we have two
events, A and&nbB)?
What is P(A | B)?
Is P(A | B) equal to P(A)?
Are events A and B dependent or independent?
A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent. Is this statement accurate?
What general conclusion would you make about mutually exclusive and independent events given the results of this problem?
a) The value of P(A∩B) = 0.
b) The value of P(A|B) = 0.
c) P(A|B) is not equal to P(A). A and B are independent events.
d) The statement "Mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent." is not accurate.
e) We can conclude that mutually exclusive events have a probability of intersection of zero and are not independent.
a) Since A and B are mutually exclusive, they cannot occur at the same time, so P(A∩B) = 0.
b) The conditional probability of A given B is defined as the probability of A occurring given that B has occurred. Since A and B are mutually exclusive, if B has occurred, then A cannot occur. Therefore, P(A|B) = 0.
c) No, P(A|B) is not equal to P(A). Since B has occurred, the sample space has been reduced to only those outcomes in which B has occurred. Therefore, the probability of A given that B has occurred can only be determined from the portion of the sample space in which both A and B occur.
However, since A and B are mutually exclusive, this probability is zero. Therefore, P(A|B) ≠ P(A).
d) The statement is not accurate. Mutually exclusive events and independent events are different concepts. Two events are mutually exclusive if they cannot occur at the same time, whereas two events are independent if the occurrence of one event does not affect the probability of the other event.
If two events are mutually exclusive, they are not independent because the occurrence of one event precludes the occurrence of the other event.
e) Mutually exclusive events have a relationship where if one event occurs, the other cannot. In contrast, independent events are events where the occurrence of one event does not affect the probability of the other event occurring.
Therefore, we can conclude that mutually exclusive events and independent events are not the same concept, and we must be careful not to confuse them.

The dimensions of a rectangular prism are (x + 1) feet by (x + 2) feet by 4 feet. The volume of the prism is (24x - 1) cubic feet. What is the value of x?
Answer:
x=3/2
Step-by-step explanation:
(x+1)(x+2)(4) = (24x-1)
4(x^2+3x+2) = 24x-1
4x^2+12x+8 = 24x-1
4x^2-12x^2+9 = 0
(2x-3)^2 = 0
2x-3 = 0
x = 3/2
The possible values of variable {x] are -
{x} = 1.146 or {x} = 1.854.
What is volume?Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write → V = ∫∫∫ F(x, y, z) dx dy dz.Given is that the dimensions of a rectangular prism are (x + 1) feet by (x + 2) feet by 4 feet.
We can write the volume of the rectangular prism as -
Volume = length x width x height
4(x + 1)(x + 2) = (24x - 1)
(x + 1)(x + 2) = 6x - 1/8
6x - (x + 1)(x + 2) = 1/8
Solving the equation graphically, we get -
x = 1.146 or x = 1.854
Therefore, the possible values of variable {x] are -
{x} = 1.146 or {x} = 1.854.

If you horizontally stretch the quadratic parent function f(x)=x^2 by a factor of 4.
When you horizontally stretch the parent function f(x)=x² by a factor of 4, the new function becomes f(x)= (1/4) x².
The function can be stretched or shrunk in different directions to produce new functions that are similar in shape but differ in size and orientation.
When you horizontally stretch the function f(x)=x² by a factor of 4, the function becomes
=> f(x)= (1/4) x².
To understand this, let's look at the equation of the parent function in detail.
The equation of the parent function f(x)=x² can be written as
=> y=x².
The x values represent the horizontal distances from the origin, and the y values represent the vertical distances from the origin.
When you stretch the function horizontally by a factor of 4, it means that the x values will be multiplied by 4. In other words, the distance from the origin in the x direction will be four times larger. The new equation of the stretched function will be
=> y= (1/4) (4x)².
We can simplify this equation to y= (1/4) x².
In mathematical terms, the horizontal stretching of a function is equivalent to multiplying the independent variable (x) by a constant factor. In this case, the constant factor is 1/4. The constant factor of 1/4 in the equation
=> y= (1/4) x²
represents the horizontal stretch by a factor of 4. The effect of this horizontal stretch is that the parabolic shape of the function will be wider and flatter compared to the parent function. The shape of the parabolic graph of the stretched function will be similar to the parent function, but the x values will be multiplied by 4.

In a density curve, the proportion of data is represented by the area under the curve.
Therefore the answer is "area under the curve".
The area under the curve represents the probability or proportion of data within a certain interval. The curve itself represents the distribution of the data and the shape of the curve provides information about the type of distribution (e.g. normal, skew, etc.).
The intervals on both the horizontal and vertical axis are used to measure the density of the data, but they do not represent the proportion of data themselves. The length of the curve has no significance in representing the proportion of data.

For a cardboard:
Area = (d) 8400 cm²Area in sqm = (b) 0.84 m(b) 3700 cm². (b) 4700 cm².(a) ₹11.75.How to calculate area and cost of painting?The area of the cardboard is:
Length = 1 m 5 cm = 105 cm
Breadth = 80 cm
Area = Length x Breadth = 105 cm x 80 cm = 8400 cm²
The area of the cardboard in square meters is:
1 m = 100 cm
Length = 1 m 5 cm = 105 cm = 1.05 m
Breadth = 80 cm = 0.8 m
Area = Length x Breadth = 1.05 m x 0.8 m = 0.84 m²
The area covered by the ribbons is the area of the cardboard that is not painted. From the previous calculations, we know that the area of the cardboard is 8400 cm² and the area that was painted is 4700 cm². Therefore, the area covered by the ribbons is:
Area covered by ribbons = Total area of the cardboard - Area that was painted
Area covered by ribbons = 8400 cm² - 4700 cm²
Area covered by ribbons = 3700 cm²
The area of the cardboard is (105 cm) x (80 cm) = 8400 cm².
The area covered by the ribbons is 3700 cm².
So, the area of the cardboard that was painted is 8400 cm² - 3700 cm² = 4700 cm².
The area of the cardboard is 8400 cm² or 0.84 m². The area covered by the ribbons is 3700 cm². So, the area that needs to be painted is the difference between the area of the cardboard and the area covered by the ribbons, which is:
8400 cm² - 3700 cm² = 4700 cm²
To convert to square meters, we divide by 10000:
4700 cm² ÷ 10000 = 0.47 m²
Therefore, the cost of painting the remaining area is:
0.47 m² × ₹25/m² = ₹11.75

At your floral business, you can sell 400 bouquets for a total benefit of $4,800. If you
earn $7,200 when selling 600 bouquets, what is your marginal benefit in this range?
The marginal benefit of selling one more bouquet within the range between 400 and 600 is $12.
How to find the marginal benefitTo find the marginal benefit in this range, we need to calculate the additional benefit of selling one more bouquet within this range.
First, let's find the benefit per bouquet in the range between selling 400 and 600 bouquets:
Total benefit in the range = $7,200 - $4,800 = $2,400
Number of bouquets in the range = 600 - 400 = 200
Benefit per bouquet in the range = Total benefit / Number of bouquets = $2,400 / 200 = $12
So for each bouquet sold within the range between 400 and 600, the benefit is $12.
Therefore, the marginal benefit of selling one more bouquet within the range between 400 and 600 is $12.
