The probability of Y is greater than or equal to 1 given that X is equal to 2 i.e. P(Y ≥ 1 | X = 2) is 2/3.

To find P(Y ≥ 1 | X = 2), we will calculate the conditional probability of Y being greater than or equal to 1 given that X is equal to 2.

First, let us find the probability of X = 2, which is the number of 2 tickets in the box divided by the total number of tickets as follows -

P(X = 2) = 3/9

Next, let us find the probability of Y ≥ 1 and X = 2, which is the number of tickets with Y greater than or equal to 1 and X equal to 2 divided by the total number of tickets as follows -

P(Y ≥ 1, X = 2) = 2/9

Finally, using the formula for conditional probability to find P(Y ≥ 1 | X = 2) we get -

P(Y ≥ 1 | X = 2) = P(Y ≥ 1, X = 2) / P(X = 2)

P(Y ≥ 1 | X = 2) = (2/9) / (3/9)

P(Y ≥ 1 | X = 2) = 2/3

Therefore, the probability of Y is greater than or equal to 1 given that X is equal to 2 is 2/3.

The probability that Jacob makes both free throws is approximately 0.1924 or 19.24%.

The probability that Jacob makes the first free throw is 0.37, and the probability that he misses it is 0.63.

If he makes the first free throw, the probability that he makes the second free throw given that he made the first is 0.52, which means the probability that he misses the second free throw given that he made the first is 0.48.

So, the probability that Jacob makes both free throws is:

P(both made) = P(made first) [tex]\times[/tex] P(made second | made first)

= 0.37 [tex]\times[/tex] 0.52

The value of the x in the circle is 17.

The angle measure of the central angle is congruent to the measure of the intercepted arc.

Therefore, let's find the value of x.

Hence,

180 - 3x(angle on a straight line) = 7x + 10

180 - 3x = 7x + 10

add 3x to both side of the equation

180 - 3x = 7x + 10

180 - 3x + 3x = 7x + 3x + 10

180 = 10x + 10

The distribution of the indicator function Z, which denotes the probability of S being greater than T, can be expressed in terms of the marginal density and the cumulative distribution function of the independent random variables S and T.

In probability theory, a random variable is a variable whose value depends on the outcome of a random event. The distribution of a random variable describes the probability of the variable taking on different values.

Now, let's consider the two independent random variables S and T with common continuous density f. We define X as the minimum of S and T, and Y as the maximum of S and T.

The indicator function Z is defined as the probability of the event {S > T}. In other words, Z takes on the value of 1 if S is greater than T, and 0 otherwise.

To find the distribution of Z, we need to consider the joint probability distribution of S and T. Since S and T are independent, their joint distribution is given by the product of their marginal distributions:

f(S,T) = f(S) * f(T)

Now, let's consider the event {S > T}. This event occurs when S is on the right side of the diagonal line T=S in the (S,T) plane. The probability of this event can be obtained by integrating the joint density over this region:

P(S > T) = ∫∫ {S > T} f(S,T) dS dT

We can simplify this integral by changing the order of integration:

P(S > T) = ∫∞-∞ ∫S∞ f(S,T) dT dS

= ∫∞-∞ f(S) ∫S∞ f(T) dT dS

= ∫∞-∞ f(S) (1 - F(S)) dS

where F(S) is the cumulative distribution function of the random variable T, which gives the probability that T is less than or equal to S.

Thus, we have obtained the distribution of Z as a function of the marginal density f and the cumulative distribution function F:

P(Z=1) = ∫∞-∞ f(S) (1 - F(S)) dS

P(Z=0) = ∫∞-∞ f(S) F(S) dS

Using the sketch, the possible range of values of x for which 2x² + 3x - 2≤0 is [-2, 0.5].

The domain of a function is a possible set of values of the independent variable. Based on the domain of a function, the codomain and range are determined.

Take the inequality as 2x²+3x-2≤0.

Solve the inequality.

2x²+3x-2≤0

(2x-1)(x+2)≤0

→ -2≤x≤0.5

The inequality is sketched in the graph and the area is also shaded for which 2x²+3x-2≤0. The range values of x mean the set of all points in the inequality -2≤x≤0.5, that is, [-2, 0.5].

To choose that a matrix is neither a diagonal matrix and are not scalar multiples of each other. The matrices will be as:

A = [ 2 1 ; 1 2 ]

B = [ -2 1 ; 1 2 ]

The matrices shown above can be used to find invertible matrices. The sum of A and B is [0 2; 2 4], which has a non-zero determinant and is therefore invertible. This choice of A and B satisfies the given conditions because they have different eigenvalues, ensuring they are not scalar multiples of each other, and are also not diagonal matrices.

The key idea behind this choice was to use matrices with the same trace and determinant, which guarantees that their sum will have the same determinant as well. This method allows us to construct examples of invertible matrices that satisfy the given conditions.

As a result, any real number higher than or equal to 12 or less than or equal to -12 is a solution to the inequality, implying that the answer is any real integer.

An inequality is a mathematical statement that compares two values and indicates whether they are equal, greater than, or less than each other. Inequalities are represented using symbols such as <, >, ≤, and ≥, which stand for "less than", "greater than", "less than or equal to", and "greater than or equal to", respectively. For example, the inequality 2 < 5 means that 2 is less than 5, and the inequality 3 ≥ 1 means that 3 is greater than or equal to 1. Inequalities are often used to describe the range of possible values for a variable, and to represent constraints in mathematical models and real-world problems. The solution of an inequality is the set of values that make the inequality true.

Here,

To solve this inequality, we first need to evaluate the expression inside the absolute value. If x is positive, then |x| = x, so the inequality becomes:

6x ≥ 72

Dividing both sides by 6, we get:

x ≥ 12

If x is negative, then |x| = -x, so the inequality becomes:

6(-x) ≥ 72

Expanding the absolute value, we get:

-6x ≥ 72

Dividing both sides by -6, we get:

x ≤ -12

Therefore, all real numbers greater than or equal to 12 or less than or equal to -12 are solutions of the inequality, meaning the solution is all real numbers.

True .The bisection method is a root-finding tool based on the intermediate value theorem. the method is also called the binary search method.

The bisection technique is a root-finding approach that is used to identify the values of x for which f(x) = 0, or the roots, of a function. Using the intermediate value theorem, the approach selects the subinterval in which the function's root must reside after repeatedly bisecting an interval containing the root of the function. This approach can be repeated again until the algorithm converges to a result that accurately approximates the function's root.

The bisection method divides the interval repeatedly to approximatively determine the roots of the given equation.

The interval will be divided using this manner until an incredibly tiny interval is discovered. The bisection method is a technique for locating roots in mathematics.

What are properties of rectangle?

A rectangle is a four-right-angle quadrilateral. It can also be classified as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.

In a rectangle, opposite sides are equal in length. So, JL is equal to KM.

We have the expressions for the lengths of JN and NM. Using this information and the fact that JKLM is a rectangle, we can set up an equation:

JN + NM = JL + KM

Substituting the given expressions, we get:

(13x - 10) + (5x + 54) = JL + KM

Simplifying the left side, we get:

18x + 44 = JL + KM

But we know that JL = KM, so we can replace both JL and KM with JL:

18x + 44 = 2JL

Now we can solve for JL:

2JL = 18x + 44

JL = (18x + 44)/2

JL = 9x + 22

Therefore, The length of JL is 9x + 22.
