Answer:
25 butterflies, 15 fruit flies, 10 bees
Step-by-step explanation:
The sample that best represents the population is option B, which includes 25 butterflies, 15 fruit flies, and 10 bees. Option B is correct.
In a study population with 2200 butterflies, 1400 fruit flies, and 800 bees, the sample size should reflect the relative proportions of each species in the population. Option B has a similar ratio with 25 butterflies (11.4% of 2200), 15 fruit flies (10.7% of 1400), and 10 bees (12.5% of 800). This sample provides a representative subset that preserves the overall distribution of species in the population.
The sample size is proportional to the population size of each insect species, and option B has the closest proportionality to the actual population. It maintains the proportional ratio of the different species found in the population.
Option B holds true.

Find the exact value, without a calculator. sin(5pi/12) = sin(5pi/6/2)
Answer:
\(\frac{\sqrt{2 + \sqrt{3} } }{2}\)
The exact value of \(sin\frac{5\pi }{12}\) is \(\frac{\sqrt{2+\sqrt{3} } }{2}\).
What is exact value of trigonometric function?The exact values of trigonometric functions are values of trigonometric functions of certain angles that can be expressed exactly using expressions containing real numbers and roots of real numbers.
According to the given question, we have
A trigonometric function, \(sin\frac{5\pi }{12}\)
Now, the exact value of \(sin\frac{5\pi }{12}\) is given by
\(sin\frac{5\pi }{12} = sin\frac{\frac{5\pi }{6} }{2}\)
⇒\(sin\frac{\frac{5\pi }{6} }{2} =\)±\(\sqrt{\frac{1-cos\frac{5\pi }{6} }{2} }\)
⇒\(sin\frac{\frac{5\pi }{6} }{2}\) =±\(\sqrt{\frac{1-cos(\pi -\frac{\pi }{6}) }{2} }\)
⇒\(sin\frac{\frac{5\pi }{6} }{2} =\) ±\(\sqrt{\frac{1+cos\frac{\pi }{6} }{2} }\)
⇒ \(sin\frac{\frac{5\pi }{6} }{2} =\) ± \(\sqrt{\frac{1+\frac{\sqrt{3} }{2} }{2} }\)
⇒\(sin\frac{\frac{5\pi }{6} }{2}\) =± \(\sqrt{\frac{2+\sqrt{3} }{4} }\)
⇒\(sin\frac{\frac{5\pi }{6} }{2} = \frac{\sqrt{2+\sqrt{3} } }{2}\) (considering positive value)
Since, \(sin\frac{5\pi }{12}\) lies in first quadrant and sin is positive in first quadrant. Therefore, we will consider only positive value.
Hence, the exact value of \(sin\frac{5\pi }{12}\) is \(\frac{\sqrt{2+\sqrt{3} } }{2}\).

Why is angle IKH a right angle?
Angle IKH must be right angle since line IH is the diameter of the circle.
What is a right angle?
A right angle is an angle that measures exactly 90 degrees, or a quarter of a full turn.
In the given diagram, we can see that line IH is the diameter of the circle.
Also if line IH is the diameter, then the angle at the circumference formed by the lines joining the diameter of the circle must be 90 degrees.
So angle KHI + angle KIH + angle IKH = 180 (sum of angles in a triangle)
angle KHI + angle KIH + 90 = 18
Thus, angle IKH must be right angle since line IH is the diameter of the circle, and angle IBH must also be 90 degrees.

Answer:
C
Step-by-step explanation:
If p and q vary inversely and p is 29 when q is 25, determine q when p is equal to 5.
Answer:If p and q vary inversely, it means that their product remains constant. So we can set up the equation:
p * q = k
where k is the constant of variation.
Given that p is 29 when q is 25, we can substitute these values into the equation:
29 * 25 = k
725 = k
Now, let's determine the value of q when p is equal to 5:
p * q = k
5 * q = 725
Dividing both sides of the equation by 5:
q = 725 / 5
q = 145
Therefore, when p is equal to 5, q is equal to 145.
Step-by-step explanation:
Answer:p1q1=p2q2
q1=25,p1=29;
p2=5,q2=?;
q2=p1q1/p2;
q2=25*29/5;

]find the midpoint m of ab a=[2,1] b=[-4,7
The coordinates of the midpoint M are (-1, 4).
To find the midpoint M of the line segment AB with endpoints A(2, 1) and B(-4, 7), we can use the midpoint formula.
The midpoint formula states that the coordinates of the midpoint M(x, y) of two points A(x₁, y₁) and B(x₂, y₂) can be found by taking the average of their respective x-coordinates and y-coordinates:
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
Let's apply the formula to find the midpoint M of AB:
x = (2 + (-4)) / 2
= -2 / 2
= -1
y = (1 + 7) / 2
= 8 / 2
= 4

A movie premiere had a full house of 350 film buffs. The price of the tickets was $6 for adults and $4 for underage. The income from ticket sales was $1,600. What is the number of adult's, x, who attended?
A 80
B 140
C 100
D 250
Answer:
C
Step-by-step explanation:
let x be number of adults and y the number of underage , then
x + y = 350 → (1)
6x + 4y = 1600 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate y
- 4x - 4y = - 1400 → (3)
add (2) and (3) term by term to eliminate y
(6x - 4x) + (4y - 4y) = 1600 - 1400
2x + 0 = 200
2x = 200 ( divide both sides by 2 )
x = 100

an urn contains 9 balls, 3 of which is(are) red. the selection of a red ball is desired and is therefore considered to be a success. if a person draws 2 balls from the urn, what is the probability of 2 successes?
Thus, the probability of drawing 2 red balls (2 successes) from the urn is 1/12.
To calculate the probability of 2 successes (drawing 2 red balls) from the urn, we'll use the following terms: total balls, red balls, and combinations.
There are 9 balls in the urn, 3 of which are red.
To find the probability of 2 successes, we need to determine the number of successful combinations and divide that by the total possible combinations.
Successful combinations: Choose 2 red balls from 3, which can be written as C(3,2) = 3! / (2! * (3-2)!) = 3.
Total possible combinations: Choose 2 balls from 9, which can be written as C(9,2) = 9! / (2! * (9-2)!) = 36.
Now, divide the successful combinations by the total possible combinations to find the probability of 2 successes:
Probability = (Successful combinations) / (Total possible combinations) = 3 / 36 = 1/12.
So, the probability of drawing 2 red balls (2 successes) from the urn is 1/12.

What is the equation of a parabola that intersects the x-axis at points (-1, 0) and (3,0)?
The equation of the parabola that intersects the x-axis at points (-1, 0) and (3,0) is y = 0.
Given that a parabola intersects the x-axis at points (-1, 0) and (3,0).We know that, when a parabola intersects the x-axis, the y-coordinate of the point on the parabola is 0. Therefore, the two x-intercepts tell us two points that are on the parabola.Thus the vertex is given by:Vertex is the midpoint of these x-intercepts=(x_1+x_2)/2=(-1+3)/2=1The vertex is the point (1,0).Since the vertex is at (1,0) and the parabola intersects the x-axis at (-1,0) and (3,0), the axis of symmetry is the vertical line passing through the vertex, which is x=1.We also know that the parabola opens upwards because it intersects the x-axis at two points.To find the equation of the parabola, we can use the vertex form:y = a(x - h)^2 + kwhere (h, k) is the vertex and a is a constant that determines how quickly the parabola opens up or down.We have h=1 and k=0.Substituting in the x and y values of one of the x-intercepts, we get:0 = a(-1 - 1)^2 + 0Simplifying, we get:4a = 0a = 0Substituting in the x and y values of the other x-intercept, we get:0 = a(3 - 1)^2 + 0Simplifying, we get:4a = 0a = 0Since a = 0, the equation of the parabola is:y = 0(x - 1)^2 + 0Simplifying, we get:y = 0Hence the equation of the parabola that intersects the x-axis at points (-1, 0) and (3,0) is y = 0.

(3 points) part c: find the value of integral from 4 to 9 of 2 times g of x minus f of x end quantity dx. show the work that leads to your answer. (4 points)
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x.
Part a:
The value of the integral from 0 to 6 of f(x)dx is 16. This can be calculated using the Fundamental Theorem of Calculus (FTC) which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫f(x)dx = F(6) - F(0)
The anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫f(x)dx = (62 + 2*6) - (02 + 2*0) = 36 - 0 = 16.
Part b:
The value of the integral from 4 to 9 of g(x)dx is 20. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫g(x)dx = G(9) - G(4)
The anti-derivative of g(x) is G(x) = x3 + 3x2, so the value of the integral is:
∫g(x)dx = (93 + 3*9) - (43 + 3*4) = 729 - 168 = 20.
Part c:
The value of the integral from 4 to 9 of 2*g(x) - f(x)dx is 68. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫(2*g(x) - f(x))dx = 2*G(9) - F(9) - [2*G(4) - F(4)]
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫(2*g(x) - f(x))dx = (2*(93 + 3*9) - (92 + 2*9)) - [2*(43 + 3*4) - (42 + 2*4)]
= (1854 - 19) - (544 - 16) = 1735 - 528 = 68.

Write an indirect proof of each statement.
If 2 x+3<7 , then x<2 .
To prove the statement "If 2x + 3 < 7, then x < 2" indirectly, we assume the negation of the conclusion (x ≥ 2) and then show that it leads to a contradiction with the given premise (2x + 3 < 7). Here's the indirect proof:
Indirect Proof:
1. Assume the negation of the conclusion: x ≥ 2.
2. If x ≥ 2, then we can multiply both sides of the inequality by 2 to maintain the inequality: 2x ≥ 4.
3. Adding 3 to both sides of the inequality, we get: 2x + 3 ≥ 7.
4. Since we assumed x ≥ 2, and we obtained 2x + 3 ≥ 7, this contradicts the given premise 2x + 3 < 7.
5. The contradiction shows that our assumption (x ≥ 2) must be false.
6. Therefore, it follows that x < 2.

How do I find the average rate of change of the function from x1 to x2?
The function is f(x)= -2x + 15 and x1= 0, x2= 3
Answer:
The average rate of change of the function f(x) = -2x + 15 from x1 = 0 to x2 = 3 is -2.
Step-by-step explanation:
To obtain the average rate of change of a function from x1 to x2, you can use the formula:
Average Rate of Change = (f(x2) - f(x1)) / (x2 - x1)
In this case, you are given the function f(x) = -2x + 15, and the values x1 = 0 and x2 = 3.
First, calculate the values of f(x1) and f(x2) by substituting x1 and x2 into the function:
f(x1) = -2(0) + 15 = 15
f(x2) = -2(3) + 15 = 9
Now we can substitute these values into the formula for average rate of change:
Average Rate of Change = (f(x2) - f(x1)) / (x2 - x1)
= (9 - 15) / (3 - 0)
= -6 / 3
= -2
Therefore, the average rate of change of the function f(x) = -2x + 15 from x1 = 0 to x2 = 3 is -2.
