We will use the concept of Probability in this question. The probability that Hannah will win both games is 0.42.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.

The probability she will win the game of chess is 0.6.

The probability she will not win  the game of chess is 0.4[1-0.6]

The probability that she will win the game of backgammon is 0.7.

The median is the middle score in the set.

To find the median, start by arranging all of the data points from smallest to largest.

In an odd-numbered set, the median will be the number in the very middle of the list.

In an even-numbered set, you will need to calculate the average of the two middle numbers.

To do this:

Step 1: Take the two middle numbers of the even-numbered set

Step 2: Add the two numbers together

Step 3: Divide the total by 2

As an example, consider this set of numbers: 5, 9, 11, 9, 7. First, you arrange them in numerical order (5, 7, 9, 9, 11). Since you have an odd number of scores, the number in the third position of the data set is the median which, in this case, is 9 (5, 7, 9, 9, 11).

To calculate the median for an even number of scores, imagine that your research revealed this set of data: 2, 5, 1, 4, 2, 7. Your first step is to put them in numerical order (1, 2, 2, 4, 5, 7). The two middle scores are 2 and 4, so you should add them together (2+4=6) and then divide 6 by 2, which equals 3. In this data set, the median score is 3.

The median is calculated by arranging the scores in numerical order, dividing the total number of scores by two, then rounding that number up if using an odd number of scores to get the position of the median or, if using an even number of scores, by averaging the number in that position and the next position.

We can conclude that under the AAS congruency condition, we can prove that △WXY ≅ △YZX.

Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.

You can move, flip, twist, and turn these triangles to produce the same effect.

When relocated, they are parallel to one another.

So, we know that;
Shared side XZ by △WXZ and △YZX.

Right angles exist between WXZ and XZY.

∠XYZ and ∠XYZ have the same values.

Now that we have the parameters, we can infer that XZ is congruent to itself according to the reflexive property of congruence, and as a result, both triangles have a congruent side.

Second, since WXZ and XZY are right angles, it follows that they are equal and hence congruent.

The last piece of information is that XWZ and XYZ are congruent.

In conclusion, the triangles are congruent according to the AAS Congruency since we have two corresponding angles and one corresponding side that are equal but the corresponding side is not with the included angles.

the X and Y Intercepts of a Line Using Algebra

When the equation is written in the slope-intercept form (y=mx +b) we can find the y-intercept by looking at the equation. The value of b is the y-intercept. This is because the y-intercept is when the x value equals 0. When x = 0, mx = 0, so when x = 0, y = b.

To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis.

When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable.

The vertex of a parabola is the point at which the parabola changes direction, the vertex of y =-x² + 4 is (0, 4).

The equation for a parabola in standard form is y = ax² + bx + c. To find the vertex of y = -x² + 4, we need to use the formula x = -b/2a. In this equation, a is -1, and b is 0, so x = 0. Therefore, the vertex of y = -x² + 4 is (0, 4).

To find the vertex of a parabola, we can use the formula x = -b/2a. In this formula, a is the coefficient of x², and b is the coefficient of x. Therefore, to find the vertex of a parabola, we need to find the coefficients of x² and x and then plug them into the formula. This formula will give us the x-coordinate of the vertex, and we can then use the equation of the parabola to find the y-coordinate of the vertex. In the case of y = -x² + 4, the coefficient of x² is -1 and the coefficient of x is 0. Plugging these values into the formula, we get x = 0. We can then use the equation of the parabola to find the y-coordinate of the vertex, which is 4. Therefore, the vertex of y =-x² + 4 is (0, 4).

Step-by-step explanation:

There will be approximately 45 million streams on the seventh day after the song's release.

To solve the problem, use the formula for exponential growth:

[tex]N(t) = N0 * (1 + r)^t[/tex]

where

N(t) is the number of streams at time t,

N0 is the initial number of streams,

r is the daily growth rate expressed as a decimal, and

t is the time elapsed in days.

In this case, N0 = 15 million, r = 0.2 (since the number of streams increases by 20% per day), and t = 7 (since we want to know the number of streams on the seventh day).

Plugin these values into the formula

[tex]N(7) = 15 * (1 + 0.2)^7\\N(7) = 15 * 1.2^7[/tex]

N(7) = 15 * 2.985984

Answer:

For a function to be continuous at a point, it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point.

The sum of these numbers is indeed 131 + 133 + 135 = 399. Therefore, the three consecutive odd numbers are 131, 133, and 135.

What are consecutive numbers ?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

Here we will use algebra to find three consecutive integers whose sum is 399. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 399. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 399

To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:

X + X + 1 + X + 2 = 399

3X + 3 = 399

3X + 3 - 3 = 399 - 3

3X = 396

3X/3 = 396/3

X = 132

Which means that the first number is 132, the second number is 132 + 1 and the third number is 132 + 2. Therefore, three consecutive integers that add up to 399 are 132, 133, and 134.

132 + 133 + 134 = 399

Since, 132 + 133 + 134 equals 399 as displayed above.

Hence ,The sum of these numbers is indeed 131 + 133 + 135 = 399. Therefore, the three consecutive odd numbers are 131, 133, and 135.

Answer: 3.5

Step-by-step explanation:

To solve for x in a square, you need to find the value of x that makes the square equal to zero. In this case, the square is given by (6x-21), so we can solve for x by setting this expression equal to zero and then solving for x.

To solve the equation (6x-21) = 0, we can use basic algebraic techniques. First, we can add 21 to both sides of the equation to get (6x-21) + 21 = 21. Then, we can use the distributive property to expand the left-hand side of the equation as follows:

(6x-21) + 21 = 21

6x - 21 + 21 = 21

6x = 21

Finally, we can divide both sides of the equation by 6 to find the value of x that makes the square equal to zero:

6x = 21

x = 21 / 6

x = 3.5

Therefore, the value of x that makes the square (6x-21) equal to zero is x = 3.5.

[tex]\longrightarrow S=\underbrace{1^2+3^2+5^2+7^2+\,\dots}_{\textrm{$n$ terms}}[/tex]

The n'th term of the sequence [tex]1^2,\ 3^2,\ 5^2,\ 7^2,\,\dots[/tex] is [tex](2n-1)^2.[/tex] So,

[tex]\longrightarrow S=1^2+3^2+5^2+\,\dots\,+(2n-1)^2[/tex]

We know the following sum,

[tex]\longrightarrow 1^2+2^2+3^2+\,\dots\,+n^2=\dfrac{n(n+1)(2n+1)}{6}[/tex]

This is expression for the sum of squares of first 'n' natural numbers. In case of '2n' natural numbers,

[tex]\longrightarrow 1^2+2^2+3^2+\,\dots\,+(2n)^2=\dfrac{2n(2n+1)(4n+1)}{6}[/tex]

We separate odd squares and even squares in the LHS.

[tex]\begin{aligned}\longrightarrow\ \ &\Big(1^2+3^2+5^2+\,\dots\,+(2n-1)^2\Big)&\\+\ \ &\Big(2^2+4^2+6^2+\,\dots\,+(2n)^2\Big)&=\dfrac{2n(2n+1)(4n+1)}{6}\end{aligned}[/tex]

We can take 4 common from the sum of even squares.

[tex]\begin{aligned}\longrightarrow\ \ &\Big(1^2+3^2+5^2+\,\dots\,+(2n-1)^2\Big)&\\+\ \ &4\Big(1^2+2^2+3^2+\,\dots\,+n^2\Big)&=\dfrac{2n(2n+1)(4n+1)}{6}\end{aligned}[/tex]

Now the sums in LHS are, as written above,

[tex]1^2+3^2+5^2+\,\dots\,+(2n-1)^2=S[/tex]

[tex]1^2+2^2+3^2+\,\dots\,+n^2=\dfrac{n(n+1)(2n+1)}{6}[/tex]

So,

[tex]\longrightarrow S+\dfrac{4n(n+1)(2n+1)}{6}=\dfrac{2n(2n+1)(4n+1)}{6}[/tex]

[tex]\longrightarrow S=\dfrac{2n(2n+1)(4n+1)}{6}-\dfrac{4n(n+1)(2n+1)}{6}[/tex]

[tex]\longrightarrow S=\dfrac{2n+1}{6}\Big[2n(4n+1)-4n(n+1)\Big][/tex]
