a political candidate has asked you to conduct a poll to determine what percentage of people support her. if the candidate only wants a 4% margin of error at a 97.5% confidence level, what size of sample is needed?
Answers
To determine the required sample size for a political poll with a 4% margin of error and a 97.5% confidence level, a formula can be used. For this scenario, the sample size required would be approximately 862 respondents.
To calculate the sample size needed for a political poll with a 4% margin of error and a 97.5% confidence level, the following formula can be used:
n = (Z^2 * p * (1-p)) / E^2
Where:
n is the sample size
Z is the Z-score associated with the desired confidence level (in this case, it is 2.24)
p is the expected proportion of support for the candidate (this value is typically unknown, so a conservative estimate of 0.5 is often used to get the maximum sample size)
E is the margin of error
Plugging in the values for this scenario, we get:
n = (2.24^2 * 0.5 * (1-0.5)) / 0.04^2
n ≈ 862
Therefore, the required sample size for this political poll is approximately 862 respondents. This sample size would provide a margin of error of 4% at a 97.5% confidence level, meaning that there is a 97.5% chance that the true proportion of support for the candidate lies within the range of the survey results plus or minus the margin of error.

The rectangle ok the right is a scaled copy of the rectangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Answers
If right is a scaled copy of the rectangle on the left then the scale factor is 1/2.
The scale factor can be calculated by dividing the corresponding lengths (or widths) of the two rectangles.
The length of the left rectangle is 20 units, and the length of the right rectangle is 10 units.
Therefore, the scale factor for the length is:
scale factor for length = length of right rectangle / length of left rectangle
= 10 / 20
= 0.5
scale factor for width = width of right rectangle / width of left rectangle
= 5 / 10
= 0.5
Since the two scale factors are the same, we can conclude that the rectangles are scaled by the same factor of 0.5 in both the length and the width.

Answers
1. Hence, det(A1) ≠ 0 so the system has a unique solution and k can take any value. False. 2. Therefore, M13 = -12k2 - 9.True. 3. Therefore, S is a subspace of P2. True.4. Hence, [a2 a] spans R2. True
Question 1: False. If the determinant of a matrix A, det(A) = 0, then the system has either no solutions or infinitely many solutions. Hence, det(A1) ≠ 0 so the system has a unique solution and k can take any value.
Question 2: True. The matrix A is a 3 x 3 matrix. M13 will be the determinant of the 2 x 2 matrix that is left when the first row and the third column are removed from A. It can be evaluated as M13 = -12k2 - 9. When c11 = 5, we have det(A) = 40k - 12. Now, det(A) = c11M11 - c12M12 + c13M13 = 5(2k-4) + 3(-3) + (-2)(-12k2-9) = 40k-12. Therefore, M13 = -12k2 - 9.
Question 3: True. To show that the set S is a subspace of P2, we need to check that it is closed under addition and scalar multiplication. Let p(t) = a1t2 + a2t + a3 and q(t) = b1t2 + b2t + b3 be any two polynomials in S and let c be any scalar in R. Then, r(t) = p(t) + q(t) = (a1+b1)t2 + (a2+b2)t + (a3+b3) is also in S since (a1+b1)t2 + (a2+b2)t + (a3+b3) + (a1+a2+a3) = a1t2 + a2t + a3 + b1t2 + b2t + b3 = p(t) + q(t). Similarly, cr(t) = c(a1t2 + a2t + a3) = (ca1)t2 + (ca2)t + (ca3) is also in S since (ca1)t2 + (ca2)t + (ca3) + a1+a2+a3 = a1t2 + a2t + a3. Therefore, S is a subspace of P2.
Question 4: True. The set of all vectors [a2 a] where a, b ∈ R spans R2. Let [x y] be any vector in R2. Then, [x y] = (x/2)[2 0] + (y/2)[0 1] + (x/2 - y/2)[1 1]. Therefore, [x y] is a linear combination of [a2 a]. Hence, [a2 a] spans R2.

a concert venue is determining the ticket price for concerts in a particular series. the sales team finds that at a price of $38 per ticket, attendance averages 1,000 people per concert. each decrease in price of $5 adds 50 people to the average attendance. find an equation for revenue, r, as a function of p, the price of tickets. what is r(25)?
Answers
An equation for revenue (r) as a function of (p) is R = 1380p - 10p²,
and R(25) = 28250.
Given that;
The cost of tickets for a specific series of concerts is set by a concert venue. The sales team discovers that 1,000 people on average attend concerts with tickets costing $38. The average attendance increases by 50 persons for every $5 decrease in price. Then,
Let 'T' be the number of times the price is decreased.
So, price;
p = 38 – 5x
x = (38 - p) / 5
And as per the given condition attendance;
a = 1000 + 50x
So, the Revenue is;
To develop an equation for revenue (r) as a function of p, the price of tickets;
R = p * a
R= p * (1000 + 50x)
But, x = (38 - p) / 5
Then,
R = P * (1000 + 50(38 - p)/5)
= p * (1000 + 380 - 10p)
= p * (1380 – 10p)
= 1380p - 10p² → (I)
To get R(25) from (I);
R(25) = 1380(25) - 10(25)²
= 34500 - 6250
= 28250
Hence, an equation for revenue (r) as a function of (p) is R = 1380p - 10p²,
and R(25) = 28250.

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y = −7x2
Answers
The quadratic function y = -7x² represents the trajectory of one of the water balloons. Since it is a quadratic function, it forms a parabola. The coefficient of x², -7, determines the shape of the parabola.
Since the coefficient is negative, the parabola opens downwards.
The x-axis represents time, and the y-axis represents the height of the water balloon. The vertex of the parabola is the highest point the water balloon reaches before falling back down. To find the vertex, we can use the formula
x = -b/2a.
In this case,
b = 0 and a = -7.
Thus, x = 0.
So, the water balloon reaches its highest point at x = 0.
Plugging this value into the equation, we find that y = 0.
Therefore, the water balloon starts at the ground, reaches its highest point at x = 0, and then falls back down.

Since the quadratic functions for the two water balloons are identical, the collision happens at all moments. The water balloons collide at every height and time, forming a continuous collision.
The quadratic function \(y = -7x^2\) represents the height (y) of a water balloon at different moments (x). When two water balloons collide, it means their heights are equal at that particular moment. To find when the collision occurs, we can set the two quadratic functions equal to each other:
\(-7x^2 = -7x^2\)
By simplifying and rearranging, we get:
0 = 0
This equation is always true, which means the water balloons collide at every moment. In other words, they collide continuously throughout their trajectory.
In conclusion, since the quadratic functions for the two water balloons are identical, the collision happens at all moments. The water balloons collide at every height and time, forming a continuous collision.
