For which inequality would x = 12 be a solution?

12 - x ≥ 4
x + 4 ≤ 12
12 x < 200
12 ÷ x > 12

Answers

Answer:

12x < 200

Step-by-step explanation:

12 - x ≥ 4

-x ≥ -8

x ≤ 8

12 is not a solution to this one.

x + 4 ≤ 12

x ≤ 8.

12 is not a solution to this one.

12 x < 200

x < 200/12

x < 16 2/3

12 is a solution.

You have a biased coin, where the probability of flipping a heads is 70%. You flip once, and the coin comes up tails. What is the expected number of flips from that point (so counting that as flip #0) until the number of heads flipped in total equals the number of tails?

Answers

The expected number of flips from that point until the number of heads flipped in total equals the number of tails is 2

How to determine the number of flips?

The given parameters are:

P(Head) = 70%

The expected number of flipping a head is:

E(x) = 70% * x

The expected number of flipping a tail is:

E(x) = (1 - 70%) * x + 1

Where 1 represents the first flip

When both values are equal, we have:

70% * x = (1 - 70%) * x + 1

Evaluate

0.7x = 0.3x + 1

Evaluate the like terms

0.4x = 1

Divide both sides by 0.4

x = 2.5

Remove the decimal

x = 2

Hence, the expected number of flips from that point until the number of heads flipped in total equals the number of tails is 2

Is 23/√3 a rational number? Again is 23 over root 3 a rational or irrational number.

Answers

Answer: irrational number

Step-by-step explanation:

Let us write it out.

[tex]\displaystyle \frac{23}{\sqrt{3} }[/tex]

Next, we will define ratoinal and irrational.

A rational number is a number that can be written as a whole number, fraction, or decimal that ends / repeats.

An irrational number is any number that cannot be turned into a fraction.

Let us see which category the number given falls into.

[tex]\displaystyle \frac{23}{\sqrt{3} } = 13.27905619\;\;\;\;\;\;\text {it goes on...}[/tex]

This means [tex]\frac{23}{\sqrt{3} }[/tex] is an irrational number.

Two players, A and B, are playing an asymmetrical game. There are n points on the game board. Each turn player A targets a pair of points and player B says whether those two points are connected or unconnected. A can target each pair only once and the game ends when all pairs have been targeted. Player B wins iff a point is connected with all other points on the very last turn, while player A wins if any point is connected with all other points on any turn but the very last one OR if no point is connected to all other points after the last turn. For what values of n does either player have a winning strategy?

Answers

The values of n does either player have a winning strategy is; Player B has a winning strategy for all n ≥ 2.

How to predict winning probability?

Let us use an example to solve this question. The game is played on the complete graph Kₙ (n ≥ 2), which consists of n vertices, each pair of vertices joined by an edge.

Now, Initially all edges are unpainted. At each turn, A chooses an edge, which B paints blue or red. Now, B will win if, after the last edge is painted, there is a vertex which is joined to all other vertices by blue edges. If that doesn't happen, then A wins.

The winning strategy of B is described by 3 rules which are;

Rule 1; Paint the last edge blue.Rule 2. Never paint an edge red if that would result in two red vertices being joined by an unpainted edge.Rule 3. Use red paint whenever permitted by Rules 1 and 2.

Thus, if n >2, the first edge will always be painted red, the second will always be painted blue.

In conclusion, when we apply that same scenario to our question it is the same result and as such Player B has a winning strategy for all n ≥ 2.

Which values of x and y would make the following expression represent a real number? (4 5i)(x yi) x = 4, y = 5 x = –4, y = 0 x = 4, y = –5 x = 0, y = 5

Answers

The product will be a real number when x = 4 and y = -5.

Which values of x and y should we use?

We have the product of complex numbers:

[tex](4 + 5i)*(x + yi)[/tex]

We want this to be a real number, then the second complex number must be the complex conjugate of the first one, so we must have:

[tex](x + yi) = (4 - 5i)[/tex]

Now, if we take the product, we get:

[tex](4 + 5i)*(4 - 5i)\\\\4*4 - 4*5i + 4*5i - (5*5)*i^2 = 16 + 25 = 41[/tex]

So we can see that the outcome is a real number.

Then we must have x = 4 and y = -5.

A = Area

a = Short Base

b = Long Base

h = Height

So what is the solution for the above trapezoid?

Following the above formula,

A = 4 * ((5+9)/2)
