Zachariah and Khai collect stamps. Zachariah has 7 American stamps out of 12 stamps. Khai has 15 American stamps out of 24 stamps. Which statement is correct?
Answers
The correct statement is "Khai has more American stamps than Zachariah." This statement is correct because Khai has 15 American stamps out of 24 stamps, while Zachariah has 7 American stamps out of 12 stamps. This means that Khai has a greater proportion of American stamps than Zachariah does.
What is proportion?Proportion is a mathematical concept which describes the relationship between two or more numbers. For example, if A is twice as large as B, then the proportion between A and B is 2:1. Proportions are used to compare two or more values and are often expressed as fractions or ratios.
To determine which statement is correct, it is important to compare the proportion of American stamps owned by each person. To do this, we can calculate the ratio of American stamps to total stamps for each person. For Zachariah, this ratio is 7/12, or 0.583. For Khai, this ratio is 15/24, or 0.625. Since Khai's ratio is larger, we can conclude that Khai has more American stamps than Zachariah does.
Another way to compare the two statements is to look at the number of American stamps each person has. Zachariah has 7 American stamps, while Khai has 15 American stamps. Since Khai has more American stamps than Zachariah, the statement "Khai has more American stamps than Zachariah" is correct.
In conclusion, the correct statement is "Khai has more American stamps than Zachariah." This statement is correct because Khai has a greater proportion of American stamps than Zachariah does, and because Khai has more American stamps than Zachariah does.

the precent chaance a certain door is locked is 70%. the key to unlock the door is one of ten keys hanging on a key rack. you get to pick two keys before walking to the door. what is the probability that you will get through the door without returning for more keys?
Answers
The required probability for the given event is given as 0.5.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
Given that,
The probability of a door being locked is 70% = 0.7
Total number of keys is 10.
The number of keys being carried is 2.
Thus, there can be two cases for getting through the door.
Case 1: The door is locked.
The probability to open the door by 1 key is 1/10.
Then, the probability to open the door by 2 keys is 2/10 = 1/5.
Case 2: The door is open.
In this case no keys are needed which means the chance of getting through is the probability of door not being locked which is given as,
1 - 0.7 = 0.3.
Now, the overall probability should consider both the cases as,
P(getting through the door) = P(Door is closed and keys open it)
+ P(The door is open)
= 0.3 + 1/5
= 0.3 + 0.2
= 0.5.
Hence, the probability to get through the door without returning for more keys is 0.5.

find the area of the surface obtained by rotating the given curve about the x-axis. x = 20 cos 3 ( θ ) , y = 20 sin 3 ( θ ) , 0 ≤ θ ≤ π 2
Answers
The area of the surface obtained by rotating the curve x = 20 cos(3θ), y = 20 sin(3θ), where 0 ≤ θ ≤ π/2, about the x-axis is calculated using the formulA for surface area of revolution
To find the area of the surface, we can use the formula for the surface area of revolution. Given a curve defined parametrically by x = f(θ) and y = g(θ), where α ≤ θ ≤ β, the surface area obtained by rotating the curve about the x-axis is given by:
A = ∫[α,β] 2πy √(1 + (f'(θ))²) dθ
In this case, we have x = 20 cos(3θ) and y = 20 sin(3θ), with 0 ≤ θ ≤ π/2. Taking the derivatives, we find f'(θ) = -60 sin(3θ) and g'(θ) = 60 cos(3θ).
Plugging these values into the surface area formula and simplifying, we get:
A = ∫[0,π/2] 2π(20 sin(3θ))(√(1 + (-60 sin(3θ))²)) dθ
Evaluating this integral will give us the exact value of the surface area of the rotated curve about the x-axis within the given range of θ.

Answers
The new vertices of ΔA'B'C' are A'(4, 4), B'(8, 8), and C'(-8, 4)
What is center of dilation?
A dilation's center is a fixed point in the plane around which all points expand or shrink. Under a dilation (k 1), the sole invariant (not changing) point is the center, which might be within, outside, or on a figure.
The center of dilation is the origin, so to find the new coordinates of each vertex, we need to multiply the original coordinates by the scale factor of 2.
A(2, 2) becomes A'(2 * 2, 2 * 2) = A'(4, 4)
B(4, 4) becomes B'(4 * 2, 4 * 2) = B'(8, 8)

Let u = [0 ] , v = [-1]
[-1] [4 ]
[-3] [-4]
[4 ] [4 ] and let W the subspace of R^4 spanned by ū and v. Find a basis of W^1, the orthogonal complement of Win R^4.
Answers
To find the basis of W^1, the orthogonal complement of the subspace W spanned by ū and v, we first need to find a basis for W. Using Gaussian elimination, we can reduce the matrix [u v] to row echelon form and get two pivot variables corresponding to the first and second columns. Therefore, a basis for W is {ū, v}. To find the basis for W^1, we need to find all vectors in R^4 that are orthogonal to W. This can be done by solving the system of equations obtained by equating the dot product of a vector in W^1 with each vector in W to zero. The resulting basis for W^1 is {(2, 1, 0, 0), (4, 0, 1, 0)}.
Let's start by finding a basis for the subspace W spanned by ū and v. To do this, we put the matrix [u v] in row echelon form:
[ 0 -1 ]
[ 1 4 ]
[-3 -4 ]
[ 4 4 ]
We can see that the first and second columns are pivot columns, so the corresponding variables are pivot variables. Therefore, a basis for W is {ū, v}.
Now, we need to find the basis for W^1, the orthogonal complement of W. We know that any vector in W^1 is orthogonal to every vector in W, so it must satisfy the following system of equations:
(2, 1, 0, 0)·ū + (4, 0, 1, 0)·v = 0
(2, 1, 0, 0)·v + (4, 0, 1, 0)·v = 0
We can solve this system of equations to get:
(2, 1, 0, 0) = 1/9*(-4, 3, 0, 0) + 1/3*(1, 0, 0, 0)
(4, 0, 1, 0) = 1/3*(0, 1, 0, 0) - 2/3*(1, 4, 0, 0)
Therefore, the basis for W^1 is {(2, 1, 0, 0), (4, 0, 1, 0)}.
The basis for W, the subspace spanned by ū and v, is {ū, v}. The basis for W^1, the orthogonal complement of W, is {(2, 1, 0, 0), (4, 0, 1, 0)}. These vectors are orthogonal to every vector in W, and together with the basis for W, they form a basis for the entire space R^4.

The class interval 0.15 - 0.30 has a frequency of 2, so there are 2 individuals in the sample with commuting times of at most half an hour. Therefore, the probability is 2/total sample size.
To construct a frequency table with a class interval width of 0.15 for the given commute times, we can organize the data into the following table:
Class Interval Frequency
0.15 - 0.30 2
0.30 - 0.45 4
0.45 - 0.60 8
0.60 - 0.75 4

0.90 - 1.05 3
1.05 - 1.20 0
1.20 - 1.35 0
1.35 - 1.50 1
Regarding the histogram, without specific information about the data and the format required, it is difficult to generate a representative histogram. However, based on the frequency table, a histogram can be created by plotting the class intervals on the x-axis and the corresponding frequencies on the y-axis.
To calculate the probability that a person chosen at random from the sample will have a commuting time of at least an hour, we sum the frequencies of the class intervals representing times equal to or greater than an hour. In this case, the class intervals 1.05 - 1.20 and 1.20 - 1.35 have frequencies of 0, so there are no individuals in the sample with commuting times of at least an hour. Therefore, the probability is 0 (0/total sample size).
To determine the probability that a person chosen at random from the sample will have a commuting time of at most half an hour, we sum the frequencies of the class intervals representing times equal to or less than half an hour. The class interval 0.15 - 0.30 has a frequency of 2, so there are 2 individuals in the sample with commuting times of at most half an hour. Therefore, the probability is 2/total sample size.

if alpha and beta are zeroes of x2-3x+q. what is the value of q, if 2 alpha+3 beta=15
Answers
The value of q is -27.
Recall Vieta's Formulas, which state that for a quadratic equation \(ax^2\) + bx + c = 0 with zeroes alpha and beta, the sum of the zeroes is equal to -b/a, and the product of the zeroes is equal to c/a.
In our equation \(x^2\) - 3x + q, the sum of the zeroes alpha and beta is -(-3)/1 = 3.
We are given that 2 alpha + 3 beta = 15. Substitute alpha = (15 - 3 beta)/2 into the equation.
Replace the value of alpha in the sum of zeroes equation: (15 - 3 beta)/2 + beta = 3.
Simplify the equation by multiplying both sides by 2: 15 - 3 beta + 2 beta = 6.
Combine like terms: 15 - beta = 6.
Subtract 15 from both sides: -beta = -9.
Multiply both sides by -1 to solve for beta: beta = 9.
Substitute the value of beta into the sum of zeroes equation: alpha = (15 - 3 * 9)/2 = -3.
Since we have the values of alpha and beta, we can find q using the product of the zeroes formula: q = alpha * beta = -3 * 9 = -27.

Let's start at (0,5) then count down 2 points, which is the "Rise"(seems like an interesting name to pick but it works).
Next, you go to the right once. Which counts as the "Run".
Remember: The slope is like a ratio, and the "y" will always go as the numerator and the "x" as the denominator. Which is why "Rise" is on top and the "Run" is on the bottom.

If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113
To find the value of P(B|A), follow these steps:
The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113.
