Therefore , on solving the provided question we can say that inequality will be  x < 2.2727272727 .

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two variables values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality.

Here,

Given :

the inequality will be

=> 3(2x – 5) < 5(2 – x)

=> 6x - 15 < 10-5x

Answer:

To find the solution to the system of equations, we need to find the values of x and y that make both equations true at the same time.

The pairs of points you provided are coordinates (x,y) which we can use to find the solution.

For the pair of points (1.8, 11.4) and (-2.8, -2.4)

We can substitute the x and y values of the first point into both equations and check if they are true.

f(1.8) = 31.8 + 6 = 7.4

g(1.8) = 1.8^2 + 41.8 + 1 = 11.16

As we can see the first equation is not true, we can safely assume that this is not the solution of the system of equations.

For the pair of points (0,6) and (0, 1)

We can substitute the x and y values of the first point into both equations and check if they are true.

f(0) = 30 + 6 = 6

g(0) = 0^2 + 40 + 1 = 1

As we can see both equations are true at the same time, this is the solution of the system of equations.

For the pair of points (-3.7,0) and (-0.27,0)

We can substitute the x and y values of the first point into both equations and check if they are true.

f(-3.7) = 3*(-3.7) + 6 = -7.1

g(-3.7) = (-3.7)^2 + 4*(-3.7) + 1 = 13.69

As we can see the first equation is not true, we can safely assume that this is not the solution of the system of equations.

For the pair of points (2.8, 5.1) and (3.6, 1.2)

We can substitute the x and y values of the first point into both equations and check if they are true.

f(2.8) = 32.8 + 6 = 11.4

g(2.8) = 2.8^2 + 42.8 + 1 = 21.96

As we can see the first equation is not true, we can safely assume that this is not the solution of the system of equations.

So the solution of the system of equations is (0,6) and (0, 1)

Percentage Decrease is the percentage change in the value when it is decreased over a period of time.

How to determine this

When 1 us dollar is exchanged at 120 rupees

And devaluated by 10%

i.e 10% of 120 rupees

= 10/100 * 120

= 1200/100

= 12 rupees devaluated

So, 120 - 12 = 108 rupees can be exchanged

How much is 450 us dollars

Let x represent the number

If 1 us dollars = 108 rupees

The probability game is solvable, and Player 1 has a strictly dominant strategy of Left (L), while Player 2 has four strictly dominated strategies. The surviving outcomes are (L, U), (L, M), (L, D), and (L, R).

This normal-form game is solvable, with Player 1 having a strictly dominant strategy of Left (L). Player 1's left strategy is strictly dominant because it will always yield a higher payoff than any other strategy for Player 1, regardless of what Player 2 does. Player 2, on the other hand, has four strictly dominated strategies: Up (U), Middle (M), Down (D), and Right (R). These strategies are strictly dominated because they will always yield a lower payoff than any other strategy for Player 2, regardless of what Player 1 does. The set of outcomes that survive the process of iterative elimination of strictly dominated strategies is (L, U), (L, M), (L, D), and (L, R). In other words, Player 1 will always choose left, and Player 2 will choose either Up, Middle, Down, or Right.

There are 8 options that Bryson could choose out of all the 12 options. We can express that as 8 over 12:

[tex]\frac{8}{12}[/tex]

Then, we simplify this by dividing both the numerator and denominator by 4, and we get:

Therefore, it is a 2/3 chance that Bryson will choose a number greater than 4, and we would say that 2/3 chance is likely, but not certain.

Answer:

1.  59% chance of drawing an odd card.  "As likely as not."

2.  A 66.67% chance of drawing a number greater than 4.  Likely

Step-by-step explanation:

We will assume that all card draws are random, as promised.  

The likihood of drawing an odd number is determined by counting how many numbers in the cards labelled 1 - 12 are odd.  There are 6 odd and 6 even cards.  Bryson's change of picking an odd card, randomly, is 6/12 (6 times out of 12 tries).  That's a 50% chance.  I don't see the options for answers, but "As likely as not" would be correct.  The chance for even is also 6/12, or 50%

To determine the likihood of picking a number great than 4, count the values greater than 4 (5,6,7,8,9,10,11,12)  There are 8 values greater than 4.  Bryson has an 8/12 chance of picking a number greater than 4.  That would mean a 66.666% chjance, which I would consider "likely."

The perimeter of the square is 4*12 inches = 48 inches

To solve for the perimeter of the square inscribed in the circle, we first need to determine the side length of the square. Since the square is inscribed in the circle, the diameter of the circle is equal to the side length of the square.

Given that the radius of the circle is 6*√2 inches, we can find the diameter of the circle by multiplying the radius by 2:

Diameter = 2 * (6√2) inches

Diameter = 12√2 inches

Now that we know the diameter of the circle is equal to the side length of the square, we can find the perimeter of the square by multiplying the side length by 4:

Perimeter = 4 * (12√2) inches

Perimeter = 48√2[tex]\sqrt{2}[/tex][tex]\sqrt{2}[/tex] inches

so the perimeter of the square is 48*√2 inches.

As we know that the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square, so the side length of the square is equal to the diameter of the circle divided by sqrt(2) .

Side length = 12*√2 inches /√2

Side length = 12 inches

so, the perimeter of the square is 4*12 inches = 48 inches

The equation of a circle with centre (a,b) and radius r is given by (x-a)^2 + (y-b)^2 = r^2.

C1 has centre (0,0) and radius 2, so its equation is (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4.

C2 touches the x and y axes each in one point, so it must have a centre on the line y=x and a radius equal to the distance from the centre to either of those points of tangency. Since the centre of C2 is on the line y=x and it is in the first quadrant, the coordinates of the centre are (1,1). The distance from the centre to the point of tangency on the x-axis is 1, so the radius is 1. The equation of C2 is (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

Therefore, The equations of the two circles are (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4 and (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

What is standard deviation ?

The standard deviation is a measure of the spread or dispersion of a set of data. It is a statistical measure that describes how much variation or deviation there is from the mean (average) of a set of values. The standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences of each value from the mean.

n = (z*sigma / E)^2

where , n = sample size

z = the z-score corresponding to the desired level of confidence (90% confidence level corresponds to a z-score of 1.645)

sigma = the estimated standard deviation of starting salaries (9000)

E = the desired margin of error (400)

Plugging in the known values ,

n = (1.645 * 9000 / 400)^2

n ≈ (40.1125)^2

n ≈ 1611.6

Integral(upper=a, lower=0) Integral(upper=0, lower=a) r2sinθ dr dθ (1/3)a3sinθ

We can evaluate this iterated integral by converting it to polar coordinates.

The first integral has an upper bound of a and a lower bound of 0. This corresponds to the radial coordinate of r, which has a lower bound of 0 and an upper bound of a. The second integral has an upper bound of 0 and a lower bound of -√(a2-y2). This corresponds to the angular coordinate of θ, which has a lower bound of -π/2 and an upper bound of π/2.

Therefore, the integral in polar coordinates is:

Integral(upper=a, lower=0) Integral(upper=0, lower=a) r2sinθ dr dθ

We can then evaluate this integral by using the formula for the area of a sector:

Area = (1/2)r2θ

Substituting in the upper and lower bounds of the integrals, we get:

(1/2)(a2)(π/2) = (1/3)a3sinθ

Therefore, the answer is (1/3)a3sinθ.
