Answer:

24 combinations

Step-by-step explanation:

For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.

Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)

By the way, welcome to brainly.  

The correct answer is the value x such that: P(X ≥ x) = 0.95

(a) The sum of independent exponential variables with the same rate parameter follows a gamma distribution. In this case, since each T_i follows an exponential distribution with a rate parameter of 1/100 (mean of 100), the sum ∑_{i=1}^{10} T_i follows a gamma distribution with shape parameter k = 10 and scale parameter θ = 100. Therefore, ∑_{i=1}^{10} T_i ∼ Gamma(10, 100).

(b) To find the probability of successful operation for at least 1.5 years, we need to calculate the cumulative distribution function (CDF) of the gamma distribution at 1.5 years (547.5 days). Using the gamma CDF, denoted by F_X(x), we have:

P(X ≥ 547.5) = 1 - F_X(547.5)

Using the gamma CDF with shape parameter k = 10 and scale parameter θ = 100, we can calculate this probability.

(c) To determine the number of spares needed to be 95% sure of successful operation for at least two years, we need to find the point where the cumulative distribution function (CDF) of the gamma distribution is 0.95. In other words, we need to find the value x such that: P(X ≥ x) = 0.95

Using the gamma CDF with the appropriate shape and scale parameters, we can solve for x.

The opposite sides of a parallelogram are congruent so a is 15.

3a+7a+2a=180 because the sum of the angles in the triangle BCD is 180 degrees.

3a+7a+2a=180

12a=180

a =180/12

a= 15

(I. e) 3a= 3(15)= 45

7a=7(15)=105

2a=2(15) =30

As a result, angle A=angle C (OPP. Angles of a Parallelogram are Equal) = A = B, D = A (OPP. angles of a parallelogram are equal)

In light of this, 7a=c = c = 105.

OPP sides in a parallelogram are parallel and equal, therefore AB is parallel to CD and BD is a transversal; as a result, angle d=2a (alternative internal angles are equal) translates to d=30.

The feature NOT associated with the function h(x) is that the domain of h(x) is [0.).

The function h(x) is defined as (x - 5)² - log₁ x + 6.

Let's analyze each given option to determine which one is NOT a key feature of h(x).

Option 1 states that the domain of h(x) is [0, ∞).

However, the function h(x) contains a logarithm term, which is only defined for positive values of x.

Therefore, the domain of h(x) is actually (0, ∞).

This option is not a key feature of h(x).

Option 2 states that the x-intercept of h(x) is (5, 0).

To find the x-intercept, we set h(x) = 0 and solve for x. In this case, we have (x - 5)² - log₁ x + 6 = 0.

However, since the logarithm term is always positive, it can never equal zero.

Therefore, the function h(x) does not have an x-intercept at (5, 0).

This option is a key feature of h(x).

Option 3 states that the y-intercept of h(x) is (0, 25).

To find the y-intercept, we set x = 0 and evaluate h(x). Plugging in x = 0, we get (0 - 5)² - log₁ 0 + 6.

However, the logarithm of 0 is undefined, so the y-intercept of h(x) is not (0, 25).

This option is not a key feature of h(x).

Option 4 states that the end behavior of h(x) is as x approaches infinity, h(x) approaches infinity.

This is true because as x becomes larger, the square term (x - 5)² dominates, causing h(x) to approach positive infinity.

This option is a key feature of h(x).

In conclusion, the key feature of h(x) that is NOT mentioned in the given options is that the domain of h(x) is (0, ∞).

Therefore, the correct answer is:

O The domain of h(x) is (0, ∞).

Answer:

D

Step-by-step explanation:

when we have the zeroes, we can build the polynomial by multiplying factors that will turn the functional value to 0 at exactly these points.

f(x) = (x - 3)(x + 6)(x - 1)

we don't need to do the full multiplications to see that the constant term of the polynomial is the result of the multiplication of all 3 constant terms of the factors :

-3 × +6 × -1 = +18

and therefore, D is the correct answer (as it is the only answer option with +18 as constant term).

The value of the expression is -27.

What is an expression?

In mathematics, an expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or a mathematical relationship between quantities. Expressions can be simple or complex, and they can include variables, constants, functions, and other mathematical objects.

First, we can simplify the expression inside the parentheses:

-(-4)(-6) - 3/5 (10+15) = 24 - 3/5 (25)

Next, we can simplify the fraction:

24 - 3/5 (25) = 24 - 15 = 9

So the expression simplifies to:

-9 ÷ 1/3

-9 x 3/1 = -27

Therefore, the value of the expression is -27.

Therefore, the solution set for the system is the point (1.8, 5.2).

A graph is a collection of points, called vertices (or nodes), and a set of connecting lines, called edges, that connect pairs of vertices. Graphs are often used to represent relationships between objects, such as roads between cities, social connections between people, or links between web pages.

Graphs can be classified based on their properties, such as whether they are directed or undirected, whether they have loops (edges that connect a vertex to itself), or whether they are connected (all vertices can be reached from any other vertex).

by the question.

To solve this system of equations graphically, we need to plot the lines represented by each equation on a coordinate plane and find their intersection point (if it exists).

First, let's rearrange the first equation to solve for y:

\(y = (2/3)x + 4\)

Now, we can plot this line by finding two points on it. For example, when x = 0, y = 4, and when x = 3, y = 6. We can then connect these points with a straight line.

\(y < 4x\). This is an inequality, so we'll shade the region below the line y = 4x. To plot the line itself, we can again find two points on it. When x = 0, y = 0, and when x = 1, y = 4. Connecting these points.

we need to shade the region below this line, since y is less than 4x. This region includes all points on the coordinate plane that satisfy y < 4x. We can shade it by drawing a dotted line along the line y = 4x and shading the region below.

Answer:

Step-by-step explanation:

The magnitude of the vector v is 10 and the direction is approximately 36.87°

The given vector v = (8, 6).

Magnitude of the vector is found using the Pythagorean Theorem as:

Magnitude of v = √(8² + 6²)= √(64 + 36)= √100= 10

Therefore, the magnitude of the vector is 10.

Direction of the vector is found using the following formula:

Direction of v = tan⁻¹(y/x)

where x is the horizontal component and y is the vertical component of the vector.

Therefore, direction of v = tan⁻¹(6/8) = tan⁻¹(0.75) ≈ 36.87°

The probability that the chosen adult have high school or some college degree but no college degree is 0.683.

From the definition of probability we know that,

Probability of Event = (Outcomes favorable to that event)/(Total number of outcomes under that event)

Total number of adults in the town is given by = 4286 + 6313 + 3033 + 1886 = 15518.

The number of adults have high school degree only = 4286

The number of adults have some college degree only = 6313

The number of adults have high school or some college degree but no college degree = 4286 + 6313 = 10599.

The probability that the chosen adult have high school or some college degree but no college degree is given by
