According to the combination method, the number of formation using the digit 4 is 192
The term combination in math is called as the mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
While we looking into the four-digit has 4 digits and the first digit is the thousands place. Then the digits 2 and 3 are less than 4, here we know that they can't take the thousands place. Here we also know that the digit 4, 5, and 6 can take this place.
Here we have the remaining 4 numbers and the remaining three digits can be taken by any of them to form a number greater than 4000.
Then the number of ways is calculated as
=> 3×4×3×2 = 72
Then the number of 5 digit numbers greater than 4000.
Here we have to observe that all five-digit numbers are greater than 4000. And here we have 5 digits and hence the number of five-digit numbers is written as
=> 5×4×3×2×1 = 120
Then the total number of ways is calculated as
=> 72 + 120 = 192
Therefore the number of numbers that are greater than 4000 which can be formed using the digits 2, 3, 4, 5, 6 without repetition is 192.

is the relationship proportional?
The relationship is proportional when John works for the hour allocated.
How to illustrate the relationship?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of that constant.
Because the rate of change in a proportional relationship is constant (and equal to the constant of proportionality), it is a linear relationship.
In this case, when John works for an hour, he is paid $15, when he works for 2 hours, he's paid $30.

Number of cars arrive at a highway toll in an hour is independent of other hours and is well-estimated by a Normal distribution with an average of 100 cars per hour and standard deviation 40 cars. What is the probability of having a total of more than 180 arrivals at the toll in the next two hours
The probability of having a total of more than 180 arrivals at the toll in the next two hours is 0.84.
The time taken to assemble follows the normal distribution.
Given mean i.e. μ = 100
Given standard deviation i.e. σ = 40
The normal random variable of a standard normal distribution is called a standard score or a z-score. Every normal random variable X can be transformed into a z score via the following equation:
z=(X−μ)/σ
where X is a normal random variable, μ is the mean of X, and σ is the standard deviation of X.
For X=180
Z=(180−100)/40= 2
For X=2
Z=(2-2)/2=0
P(a<X<b)=P(X<b)–P(X<a)
P(20<X<22)=P(X<180)−P(X<2)
=P(Z<2)−P(Z<0)
=0.8413

As per the given standard deviation, the probability of having a total of more than 180 arrivals at the toll in the next two hours is written as 0.84.
Here we have given that the number of arrive at a highway toll in an hour is independent of other hours and is well-estimated by a Normal distribution with an average of 100 cars per hour and standard deviation 40 cars.
Which means that
mean = 100
And the value of standard deviation = 40
Now, we have to use the normal random variable of a standard normal distribution is called a standard score or a z-score.
Then the value of z score is calculated as
=> z=(X−μ)/σ
Apply the values on it then we get
=> z = (180−100)/40= 2
Therefore, the probability is calculated as
=> P(20 < x <22) = P(X<180)−P(X<2)

The equation of the blue line is y = –x 5. manipulate the orange line by setting the sliders so its slope, m, is –1 and its y-intercept, b, is –3. does the system appear to have a solution after the changes?
The system does appear to have a solution after the changes.
The equation of the orange line after the changes is y = -x - 3. The system appears to have a solution after the changes because the equations for both lines are in the same form. The blue line has a slope of -5 and the orange line has a slope of -1. This means that the lines have the same slope and the same y-intercept. This means that the two lines are parallel and will intersect at the point (-3,3).
To calculate the point of intersection, we can plug in -3 for x in both equations and solve for y.
For the blue line: y = -(-3)^5 = 3
For the orange line: y = -(-3) - 3 = 3
This means that the point of intersection for these two lines is (-3,3). Therefore, the system does appear to have a solution after the changes.

If the team's engagement score was 4. 6 this month, then with a improving rate of 11% per month, the score 3 months ago is approximately 3.46.
Therefore, the engagement score 3 months ago was approximately 3.46.
To find the engagement score 3 months ago, we need to first find the rate of improvement over 3 months. We can do this by multiplying the monthly rate of improvement by 3. So the rate of improvement over 3 months is
11% × 3 = 33%
If rate of improvement over 3 months is 33%, then
((current engagement score) - (score 3 months ago))/(score 3 months ago) × 100 = 33
that is
[tex]\frac{(current\ engagement\ score) - (score\ 3\ months\ ago)}{score\ 3\ months\ ago} \ 100 = 33[/tex]
Let score 3 months ago be a, then
(4.6 - a)/ a × 100 = 33, that is
[tex]\frac{4.6\ -\ a}{a} \ 100 = 33[/tex]
Multiplying by a and dividing by 100 on both sides
4.6 - a = 0.33a

What is Reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
Given data ,
Let the function be represented as f ( x )
Now , the transformed function is given as g ( x )
The function g ( x ) has the x coordinates as the additive inverse
So , it must be a reflection transformation
And , the axis of transformation is y axis
So , when you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y)

b) The estimate for the consumption in 2011 is given as follows: 61.4 gallons.
How to model the situation?The yearly increase in the consumption is constant, meaning that a linear function is used to model this situation.
The slope-intercept definition for the linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the yearly increase in consumption.b is the intercept, representing the consumption in the year of 2000.The consumption increases by about 2.4 gallons per person each year, hence the slope is of:
m = 2.4.
In 2005, which is five years after 2000, the excess consumption was of 47 gallons, hence the intercept b is calculated as follows:
47 = 2.4(5) + b
b = 47 - 2.4(5)
b = 35.
Meaning that the function is defined as follows:
y = 2.4x + 35.

The correct answer is an option (b)
In this question we have been given an expression startroot 64 r superscript 8 baseline endroot.
i.e., √(64r^8)
We need to simplify this expresison.
We know that 64 is square of 8.
8^2 = 64
So, we can write given expression as,
√(64r^8)
= √(8^2r^8)
= √[8^2r^(2 * 4)]
We know that for the properties of exponents i.e., non-zero numbers a, m,n
(a^m)^n = a^(m * n) ............(1)
So, √[8^2r^(2 * 4)]
= √[8^2(r^4)^2]
= √((8r^4)^2)
Square-root is nothing but the 1/2 power of number/expression.
i.e., √((8r^4)^2)
= [(8r^4)^2]^1/2
= (8r^4)^(2 * 1/2) ...........(from (1))
= (8r^4)^1

A side of the triangle below has been extended to form an exterior angle of 144°. Find the value of x.
The value of x in the right angle triangle is 54 degrees.
How to find the angle of a triangle?The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
Therefore, exterior angle theorem can be used to find the angle x.
The triangle is a right angle triangle.
A right angle triangle is a triangle that has one of its angles as 90 degrees.
Therefore, let's find the angle x using exterior angle theorem.
90 + x = 144
subtract 90 from both sides of the equation
90 + x = 144
90 - 90 + x = 144 - 90
x = 54 degrees
Therefore, the angle x is 54 degrees.
