The system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.

The stability of a linear system can be determined by analyzing the magnitude of its impulse response −

|h[n]| ≤ M for some finite M

In this case, the impulse response is h[n] = 0.25nu[n], where nu[n] is the unit step function. Since the magnitude of h[n] is 0.25 for all n, the system is stable since 0.25 is a finite number that is less than any M.

To summarize, the system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.

Alisha needs to use a fraction of 3/8 of each of the ingredients on the recipe.

We know that a pancake recipe calls for 8 eggs and some other ingredients.

But Alisha only has 3 eggs, so she needs to adjust the recipe.

The fraction of each one of the other ingredients that she needs to use is equal to the fraction between the number of eggs that she has and the number of eggs that the recipe calls, it is:

The solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:

x = -4 or x = 8

What is inequality?

A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is the set of all solutions.

We can solve this absolute value equation by first isolating the absolute value term on one side of the equation and then solving for both possible cases. Here are the steps:

|4 − 2x| + 6 = 18

|4 − 2x| = 12 (subtract 6 from both sides)

Now we have an absolute value equation with no constant term. We can split this equation into two cases: one where the expression inside the absolute value is positive, and one where it is negative. For each case, we can solve for x:

Case 1: 4 - 2x > 0

If 4 - 2x is positive, then we can drop the absolute value bars and write:

4 - 2x = 12

-2x = 8

x = -4

So one solution is x = -4.

Case 2: 4 - 2x < 0

If 4 - 2x is negative, then we must flip the inequality when dropping the absolute value bars:

-(4 - 2x) = 12

-4 + 2x = 12

2x = 16

x = 8

So the other solution is x = 8.

Therefore, the solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:

x = -4 or x = 8

Answer:

15 prints

Step-by-step explanation:

Let's call the number of small prints sold as "x".

The number of medium prints sold is then (52 - x) prints.

We know that the total revenue from all the prints sold is $2,975, so we can set up the following equation:

$2975 = (x * $50) + ((52 - x) * $75)

Expanding and solving for x:

$2975 = $50x + $3900 - $75x

$2975 = $3900 - $25x

$-925 = -$25x

x = 37

So, Catori sold 37 small prints and (52 - 37) = 15 medium prints

the data y = (y1,..., yn) are a sample from a normal distribution with unknown mean θ and known standard deviation σ = 2. Our prior distribution p(θ) is normal with mean 0 and standard deviation σ0.

y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1 y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1

We have two cases for Ф,

1.  Ф=1; it implies that Pr(Ф=1)=0.5, while y~N(1,α²)

2. Ф=2; it implies that Pr(Ф=2)=0.5, while y~N(2,α²)

Now,

For 1st case of α=2,

We have marginal probability density formula

p(y)=∑p(yIФ)p(Ф)

=p(yIФ=1)p(Ф=1)+p(yIФ=2)p(Ф=2)

=N(yI1,2²)(1/2)+N(yI2,2²)(1/2)

=(1/2)[N(yI1,2²)+N(yI2,2²)]

Now.

For Pr(Ф=1Iy=1) at α=2

We have,

=p(Ф=1Iy=1)

=[p(y=1,Ф=1)]/[p(y=1)]

=[p(y=1IФ=1)p(Ф=1)]/[p(y=1)]

={(1/)exp[(-1/(2*2²))(1-1)²(1/2)]}/{(1/)(1/2)[exp[(-1/(2*2²))(1-1)²]+exp[(-1/(2*2²))(1-2)²]}

=0.53 Answer

Now, to describe the changes in shape of Ф when α is increased and decreased deviation

The formula for posterioir density is p(ФIy)=p(yIФ)p(Ф)/p(y)

=exp[(-1/(2α²)(y-Ф)²]/{exp[(-1/(2α²)(y-1)²]+exp[(-1/(2α²))(y-2)²]}

Now at Ф=1 and solving the equation, we get

p(Ф=1Iy)=1 / {1+exp[(2y-3)/2α²]}

Similarly at Ф=1 and solving the equation, we get

p(Ф=2Iy)=1 / {1+exp[(2y-3)/2α²]}

Conclusion:

α² → ∞ ⇒p(ФIy) → p(Ф) = 1/2

α² → 0 ⇒ two cases

y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1

y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1

Correlation is a statistical number derived based on historical data (profitability), and, contrary to popular belief, it is not constant and can change over time.

Correlation is a statistical term that reflects how much two or more variables vary in relation to one another.

The correlation coefficient is evaluated on a scale ranging from + 1 to - 1. The degree of correlation between two variables is denoted by + 1 or -1. When one variable rises as the other rises, the correlation is positive; when one falls as the other rises, the correlation is negative.

y = mx + c ( m is the slope and c the y- intercept )

here slope m = [tex]\frac{3}{2}[/tex] and y- intercept c = 0 , then

Answer:

f(x) = 100 (3)^x  <===> C

f(x) = 100 (3.5)^x  <===> B

f(x) = 100 (4)^x <===> A

Step-by-step explanation:

Since the base of each of the exponential functions is the same, the higher the base, the higher up the graph will be with respect to another base with a lower value

This can be easily determined by choosing a specific value for x for each equation and seeing what the f(x) value is

Let's choose x = 2

For f(x) = 100 (3)^x, at x = 2 we get f(2) = 100(3)^2 = 100 x 9 = 900

For f(x) = 100 (3.5)^x, at x = 2 we get f(2) = 100(3.5)^2 = 100 x 12.25 = 12.25

For f(x) = 100 (4)^x, at x = 2 we get f(2) = 100(4)^2 = 100 x 16 = 1600

So for a specific value of x, the higher the base, the higher the graph is relative to the x-axis

So the matches are:

f(x) = 100 (3)^x  <===> C

f(x) = 100 (3.5)^x  <===> B

f(x) = 100 (4)^x <===> A

The values of the letters are:

A =  $37.5

B = $16.95

If q² – 4pr > 0, the roots of the quadratic equation px² + qx + r = 0 will be: "negative, if p, q, and r are positive". Therefore, Suman answered correctly.

In Mathematics, a quadratic function can be defined as a mathematical expression which defines and represent the relationship that exists between two (2) or more variable on a graph, with a maximum exponent of two.

Generally speaking, the standard form of a quadratic function is given by ax² + bx + c = 0.

Assuming the roots of the quadratic function are a and b. Therefore, the sum of the roots of the quadratic function would be equal to -q/p;

a + b = -q/p

ab = r/p

This ultimately implies that, the nature of the roots would depend on the value of p, q and r, which make Zain's answer to be wrong.

Answer:

52 cats

Step-by-step explanation:

Let d be the number of dogs, then c = 2d + 10 is the number of cats.

The total number of animals is 73, so we have d + c = 73.

Substituting c = 2d + 10 into this equation, we get d + 2d + 10 = 73.

Combining like terms, we get 3d + 10 = 73.

Solving for d, we have 3d = 63, so d = 21.

Thus, there are 21 dogs and 2 * 21 + 10 = 52 cats up for adoption.

The rate of change of f'(x) at (1, 13) is 25.

We have,

To find the rate of change of the derivative f'(x) at point (1, 13), we first need to find the derivative of the function f(x).

Given: f(x) = 14x² - x³

To find f'(x), we differentiate f(x) with respect to x:

f'(x) = d/dx (14x² - x³)

= 28x - 3x²

Now, to find the rate of change of f'(x) at x = 1,

we substitute x = 1 into the derivative expression f'(x):

f'(1) = 28(1) - 3(1)²

= 28 - 3
