The function which has the constant rate of change as -1/4 is the function(i) whose graph passes through the points (-2,2) and (2,1).

The "Rate-Of -Change" of a graph is defined as a measure of how much one variable changes in relation to another variable. It is calculated by finding slope of line which represents the graph.

The graph of function(i) is a coordinate-plane with a straight line with a negative slope and line passes through (-2, 2) and (2, 1).

The equation is written as :

⇒ y - 1 = [(1-2)/(2+2)]×(x -2),

⇒ y - 1 = (-1/4)×(x -2),

⇒ y = -(x/4) + 1/2 + 1,

⇒ y = -x/4 + 3/2,

Therefore, the constant-additive rate of change = -1/4.

What does a statistical correlation mean?

A statistical metric known as correlation, which is given as a number, describes the strength and direction of a relationship between two or more variables.

                         Although there may be a correlation between two variables, this does not necessarily imply that the change in one variable is what led to the change in the values of the other variable.

Why correlation, you ask?

In common conversation, we use the word correlation to describe situations where two or more items seem to be connected.

Find x:

Tim was driving for 5 hours before he caught up to Dora.

The answer is (a) 5 hours.

To solve this problem, we can use the formula:
distance = rate × time
Let's denote the time Tim drove as t hours.

Since Dora started driving one hour earlier, her driving time would be (t + 1) hours.
Dora's distance: 75 kph × (t + 1)
Tim's distance: 90 kph × t
Since Tim catches up to Dora, their distances will be equal:
75(t + 1) = 90t
Now we can solve for t:
75t + 75 = 90t
75 = 15t
t = 5.

The answer is (a) 5 hours.

The length of the hypotenuse BC in right  angled triangle ABC is 3.605 units.

A triangle is said to be right angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle. Consequently, other names for this triangle include the right triangle and 90-degree triangle.

In right angle triangle if 90 degree angle is A then

\(AB^{2} +AC^{2} = BC^{2}\)

And here length of altitude AB equals to 3 units and length of base  AC equals to 2 units And here length of hypotenuse BC equals to \(\sqrt{13}\) units

\(AB^{2} +AC^{2} = BC^{2}\)

\(3^{2} +2^{2} = \sqrt{13}\)

Step-by-step explanation:

When bound to CR1 (complement receptor 1), C3b is cleaved by Factor I, resulting in the generation of pathogen-associated B-cell co-receptor ligands.

The complement system is a part of the immune system that plays a crucial role in recognizing and eliminating pathogens. C3b is a component of the complement system that can opsonize pathogens, marking them for phagocytosis by immune cells. When C3b binds to CR1, which is present on B cells, the cleavage of C3b occurs. This cleavage is performed by an enzyme called Factor I, which is regulated by co-factors such as membrane cofactor protein (MCP). Factor I acts by proteolytically cleaving C3b into smaller fragments, resulting in the generation of pathogen-associated B-cell co-receptor ligands.

These pathogen-associated B-cell co-receptor ligands play a role in the activation of B cells, promoting their immune response against the pathogen. By cleaving C3b, Factor I helps regulate and fine-tune the complement system, ensuring an appropriate immune response while preventing excessive inflammation or damage to host tissues.

The probability of X being equal to 4 is 0.1755.

The probability of X being less than 4 is 0.60687.  

The probability of X being greater than or equal to 4 is 0.39313.

The probability of X being between 4 and 6 (inclusive) is 0.49719.

The first thing we need to do is to identify the parameters of the Poisson process. In this case, we are given that the mean is u=5.

(a) P(4):

P(X=4) = (e^(-u) * u^x) / x!

= (e^(-5) * 5^4) / 4!

= 0.1755


(b) P(X<4):

P(X<4) = P(X=0) + P(X=1) + P(X=2) + P(X=3)

= (e^(-5) * 5^0) / 0! + (e^(-5) * 5^1) / 1! + (e^(-5) * 5^2) / 2! + (e^(-5) * 5^3) / 3!

= 0.12465 + 0.20593 + 0.17547 + 0.10082

= 0.60687



(c) P(X>=4):

P(X>=4) = 1 - P(X<4)

= 1 - 0.60687

= 0.39313



(d) P(4<=X<=6):

P(4<=X<=6) = P(X=4) + P(X=5) + P(X=6)

= (e^(-5) * 5^4) / 4! + (e^(-5) * 5^5) / 5! + (e^(-5) * 5^6) / 6!

Let's denote the ages of the two remaining men as x and x + 3 (since one is 3 years older than the other).

We know that the average age of 6 men is 35 years. So, the sum of their ages is 6 * 35 = 210 years.

We also know that the average age of four of them is 32 years. So, the sum of their ages is 4 * 32 = 128 years.

To find the sum of the ages of the two remaining men, we subtract the sum of the ages of the four men from the sum of the ages of all six men:

210 - 128 = 82 years.

Now, we can set up an equation to solve for the ages of the remaining two men:

x + (x + 3) = 82.

Combining like terms, we get:

2x + 3 = 82.

Subtracting 3 from both sides:

2x = 79.

Dividing both sides by 2:

x = 39.5.

So, one of the remaining men is 39.5 years old, and the other is 39.5 + 3 = 42.5 years old.

To determine how much of the variation in average annual energy expenditures is explained by the least-squares regression line, we can look at the coefficient of determination (R-squared) for the regression model.

R-squared is the proportion of the variance in the dependent variable (in this case, average annual energy expenditures) that is explained by the independent variable(s) (in this case, the variable(s) used in the regression model).

The formula for R-squared is:

R-squared = 1 - (SSres / SStot)

where SSres is the sum of squared residuals (i.e., the sum of the squared differences between the actual values and the predicted values) and SStot is the total sum of squares (i.e., the sum of the squared differences between the actual values and the mean value of the dependent variable).

Since the question does not provide any data or regression model, we cannot calculate the exact value of R-squared. However, if you have the data and the regression model, you can calculate R-squared using the above formula and round the answer to at least one decimal place.

We want to get the expected value for the given experiment, we will see that it is equal to -1/6 points, so the correct option is "negative one-sixth"

For an experiment with events {x₁, x₂, ..., xₙ}, each one with probability {p₁, p₂, ..., pₙ}, the expected value is given by:

EV = x₁*p₁ + ... + xₙ*pₙ

Here we have two events:

Let's find the probabilities of each one of these.

She gets 9 points if the sum of the two dice is equal to 8 or 12.

Each dice has 6 outcomes.

Then a combination of two dice has a total of 6*6 = 36 outcomes.

The outcomes that add to 8 or 12 are:

dice 1   dice 2  sum

2           6            8

3           5            8

4           4            8

5          6             8

6           2            8

6           6            12

So 6 out of the 36 outcomes, then the probability of this event is:

p₁ = 6/36 = 1/6

And the other event is for all the other outcomes, so the probability is just:

p₂ = 5/6

Then the expected value is:

EV = (+ 9 points)*(1/6) + (-2 points)*(5/6)  = -1/6 points.
