The probability of picking two black marbles from a box at random without replacement is 10/91 . The probability of drawing a black marble first is 5/14 . What is the probability of picking a second black marble, given that the first marble picked was black?
Answers
The probability of picking a second black marble is 4/13
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Probability helps us know the chance an event has to occur. The closer it gets to zero(0) the less chance it has to occur. The closer it gets to one(1) the more chance it has to occur.
Therefore, The probability of picking a second black marble is 4/13

The number of yards of the automobile of length 'x' meters will be 1.10x yeads.
What is conversion?Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
A meter is about 1 ¹/₁₀ yards.
Convert the mixed fraction number to a decimal number. Then we have
1 meter = 1 ¹/₁₀ yards
1 meter = 1 + ¹/₁₀ yards
1 meter = 11 / 10 yards
1 meter = 1.10 yards
Let the length of the automobile be 'x' meters. Then the number of yards in 'x' meters is given as,
⇒ x × (1.10)
⇒ 1.10x yards
The number of yards of the automobile of length 'x' meters will be 1.10x yeads.

When lisa was born, her parents put 8000 into a college fund account
Answers
The initial deposit was $8000 and after 18 years the simple interest earned is $12960. So, the total amount for Melissa in college account is $20,960.
What is Simple Interest?
Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
The amount that was put in college fund for Melissa, P = $8000
The rate at which interest was earned is, R = 9%
The time period after which the account was checked, T = 18 years
The formula for Simple Interest is -
S.I. = (P R T)/100
Substitute the values into the equation -
S.I. = (P R T)/100
S.I. = (8000 × 9 × 18)/100
S.I. = 1296000/100
S.I. = 12960
The amount of interest earned in 18 years is $12960.
The total amount after 18 years will be -
Total Amount = Initial deposit + Interest earned
Total Amount = $8000 + $12960
Total Amount = $20960
Therefore, the total amount after 18 years is $ 20,960.

Solve this system of linear equations. Separate

2x + 2y = -8
-13x + 7y = -48
Enter the correct answer.
Answers
Answer:
x = 1, y = - 5
Step-by-step explanation:
2x + 2y = - 8 → (1)
- 13x + 7y = - 48 → (2)
multiplying (1) by 7 and (2) by - 2 and adding will eliminate y
14x + 14y = - 56 → (3)
26x - 14y = 96 → (4)
add (3) and (4) term by term to eliminate y
40x + 0 = 40
40x = 40 ( divide both sides by 40 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
2(1) + 2y = - 8
2 + 2y = - 8 ( subtract 2 from both sides )
2y = - 10 ( divide both sides by 2 )
y = - 5

Trapezoid PQRS having vertices P(0, 0), Q(0, 4), R(6, 4), and S(12, 0),
has the length of the midsegment as 11.07 units.
What is a trapezoid?
A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.
The length of the mid segment of trapezoid is half the sum of the lengths of the two parallel sides, PQ and RS.
The points for vertices are given as - P(0, 0), Q(0, 4), R(6, 4), and S(12, 0).
Length of sides PQ and RS is given as -
The line segment PQ = √(x2 - x1)² + (y2 - y1)²
PQ = √(0 - 0)² + (4 - 0)²
PQ = √0² + (4)²
PQ = √0 + 16
PQ = √16
PQ = 4 units
The line segment RS = √(x2 - x1)² + (y2 - y1)²
RS = √(12 - 6)² + (0 - 4)²
RS = √(6)² + (-4)²
RS = √36 + 16
RS = √50
RS = 5√2 units
To find the mid segment add the length of PQ and RS.
So, the equation will be -
Midsegment = PQ + RS
Midsegment = 4 + 5√2
Midsegment = 11.07 units
Therefore, the length of midsegment is 11.07 units.

what is missing is the definition that QS is the height and therefore standing at a right angle (90°) at PR.
then this can be solved.
we use Pythagoras
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.
let's start with the triangle PQS.
21² = 15² + QS²
441 = 225 + QS²
QS² = 216
QS = sqrt(216) = sqrt(36×6) = 6×sqrt(6) = 14.69693846...
now for triangle QSR
(5x - 16)² = (3x - 4)² + QS²
25x² - 160x + 256 = 9x² - 24x + 16 + 216
16x² - 136x + 24 = 0
2x² - 17x + 3 = 0
the solution to a quadratic equation
ax² + bx + c = 0
is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = (17 ± sqrt(17² - 4×2×3))/(2×2) =
= (17 ± sqrt(289 - 24))/4 = (17 ± sqrt(265))/4
x1 = (17 + 16.2788206...)/4 = 8.319705149...
x2 = (17 - 16.2788206...)/4 = 0.180294851...
but using x2 in side lengths 3x - 4 or 5x - 16 gives us negative side lengths. that does not make any sense for actual side lengths.
so, x1 is our solution :

Answers
The joint probability mass function given by PX, Y(a, b) = {1/4a, for 1≤ b≤a≤4, otherwise is indeed a joint probability mass function because the sum of all the joint probabilities is equal to 1.
To find the marginal probability mass function of X, we need to sum the joint probabilities over all possible values of Y:
PX(a) = ∑ PX, Y(a,b) = ∑ (1/4a) = 1/4
To find the marginal probability mass function of Y, we need to sum the joint probabilities over all possible values of X:
PY(b) = ∑ PX, Y(a,b) = ∑ (1/4a) = 1/4
To find P(X = Y + 1), we need to find the joint probability of X = a and Y = a-1, where a = 2,3.
P(X = Y + 1) = PX, Y(2,1) + PX, Y(3,2) = (1/42) + (1/43) = 1/4 + 3/12 = 5/12
So the probability that X is one more than Y is 5/12.
It's important to note that the given joint probability mass function is valid as it satisfies the non-negativity and the condition of summing to 1.

if matrix a is symmetric show that any two eigenvectors of a correspond to different eigenvalues are orthogonal
Answers
A symmetric matrix is a square matrix that is equal to transpose of itself. If A is a symmetric matrix, then it satisfies the condition: A = AT. (AT is the inverse of A )
A square matrix with real numbers or elements is said to be an orthogonal matrix if its transpose is equal to its inverse matrix. Or we can say when the product of a square matrix and its transpose gives an identity matrix, then the square matrix is known as an orthogonal matrix.
Suppose λ and μ are 2 distinct values of matrix A.
For the matrix to be Symmetric,
( Ax,y)=(x,Ay)
condition needs to be satisfied.
Here, ( x,y) is dot product between vectors x and y
λ (u,v) = (λu,v)
where u,v are eigen vectors for eigen values λ and μ
λ(u,v) = (Au,v)
λ(u,v) = (u,Av)
λ(u,v) = μ(u,v)
λ(u,v) = μ(u,v)
but λ≠μ
∴ (u,v) = 0.
