Is there an AAA similarity?

Answer:

the correct answer is 7 and 9

Answer:

7 and 9

Step-by-step explanation:

14 ÷ 2 and 18÷ 2

= 7 and 9

0*.5+2*.2+4*.15+6*.1+10*.05= 2.1

The expected value of the winnings from a game is 2.1.

Expected value is used when we want to calculate the mean of a probability distribution. The weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value.

For the given situation,

Payouts, x = 0, 2, 4, 6, 10

Probabilities, P(x) = 0.5, 0.2, 0.15, 0.1, 0.05

The formula of expected value is [tex]E ( X ) = \mu = \sum [xP( x )][/tex]

⇒ [tex]E(X)=(0)(0.5)+(2)(0.2)+(4)(0.15)+(6)(0.1)+(10)(0.05)[/tex]

⇒ [tex]E(X)=0+0.4+0.6+0.6+0.5[/tex]

⇒ [tex]E(X)=2.1[/tex]

Hence we can conclude that the expected value of the winnings from a game is 2.1.

The relationship between the variables in the table is an inverse variation The equation to model is y = 42/x.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 8 is an equation.

We have,

x:  2  6  7  14

y: 21  7  6  3

Now,

When x = 2, y = 21

This can be written as,

y = kx

21 = 2k

k = 21/2

The equation is y = (21/2)x _____(1)

or

y = k/x

21 = k/2

k = 42

The equation is y = 42/x _____(2)

Now,

We will check which equation fits the table.

From (1)

y = (21/2)x

When x = 6,

y = (21/2) x 6 = 21 x 3 = 63

From (2),

When x = 6,

y = 42/6 = 7

When x = 7,

y = 42/7 = 6

When x = 14,

y = 42/14 = 3

This equation satisfies the table.

Thus,

The relationship is an inverse variation.

The equation is y = 42/x.

Let's organize what is given to us from the problem.

We are given a graph of a function.

We need to analyze the graph to determine the domain and range of the graph.

If we take a look at our x values, we see that our graph starts at x = 3 and continues infinitely.

∴ we can write the graph's x-values as [3, ∞), or x ≥ 3.

⇒ The domain of the graph is equal to x ≥ 3.

If we take a look at our y values, we see that our graph begins at y = 1 and also continues infinitely.

∴ we can write the graph's y-values as [1, ∞), or y ≥ 1.

⇒ The range of the graph is equal to y ≥ 1.

Step-by-step explanation:

$2000 * 3.5% * 4 = $8000 * 0.035 = $280

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11 gets 3a³ + 4a² - a + 5.

The answer in descending powers of a is 3a³ + 4a² - a + 5.

A polynomial is a mathematical expression consisting of a sum of powers in one or more variables (indeterminates) with non-negative integer exponents.

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11                                        

(3a³ + 8a - 6) + (4a² - 9a + 11) = 3a³ + 4a² - a + 5

The coefficients of  a³, a², a and 1 is 3, 4, -1 and 5 respectively.                      

Descending powers of a in the polynomial is a³, a², a. So the answer in descending powers of a is 3a³ + 4a² - a + 5.

Answer:

16

Step-by-step explanation:

16 is a positive multiple of 8, in which 16²=256>100 and 16<20 are true statements.

Answer:

[tex]$x=\boxed{16}$[/tex]

Step-by-step explanation:

Since $x$ is a positive multiple of 8, it must be at least 8. Since $x^2>100$ and $x$ is at least 8, the only solution is $x=16$.

To verify this, note that $x=8$ does not satisfy the inequality $x^2>100$, but $x=16$ does, so $x=16$ is the only solution that works.

Therefore, $x=\boxed{16}$.

The correct option that tests the given claim on statistics is; D. False. In statistics, results are not reported with 100% certainty. Because statistical studies draw on samples, and because there is variation within groups, results cannot be reported with 100 % certainty.

Statistical research is defined as the rigorous development of improved or new statistical methods grounded in probability and statistical theory.

Statistical data analysis is basically a procedure that is used to perform various statistical operations.

Now, from the question, the claim is that In statistics, results are always reported with 100 % certainty.

Now, this claim needs to be examined because there is no perfect human being and as such since statistics is drawn from a lot of samples and groups, there is guaranteed to be some form of variability in responses or results as the case may be.

Answer:

Step-by-step explanation:

The given values are:

Standard deviation,

[tex]\sigma=18.4[/tex]

Margin of error,

[tex]E = 4.1[/tex]

Using the table,

[tex]Z_{(\frac{0.02}{2} )}=2.326[/tex]

Now,

The sample size will be:

⇒  [tex]n=(\frac{Z_{(\frac{0.02}{2})\times \sigma}}{E} )^2[/tex]

On substituting the values, we get

⇒      [tex]=(\frac{2.326\times 18.4}{4.1} )^2[/tex]

⇒      [tex]=(\frac{42.7984}{4.1} )^2[/tex]

The factored form of quadratic equation 2x² + 7x + 3 is 2(x + 1/2) (x + 3)

A quadratic equation can be expressed in:

- Standard form: y = ax² + bx + c

- factored form: y = a(x - x₁) (x - x₂)

Here, x₁ and x₂ are the roots of the given function.

Suppose we are given a quadratic equation:

y = ax² + bx + c

To find the factored form, use the following properties:

x₁ . x₂ = c/a

x₁ + x₂ = - b/a

In this case, the quadratic function is:

y = 2x² + 7x + 3

We have to find x₁ and x₂ such that:

x₁ . x₂ = 3/2

x₁ + x₂ = - 7/2

Hence,

x₁ = - 1/2

x₂ = - 3

Therefore the factored form is:

y = 2(x + 1/2) (x + 3)

Step-by-step explanation:

The triangle has a small square in the corner representing a 90 degree angle. This is a right triangle so we can use the Pythagorean Theorem to solve for the sides.

[tex]a^2+b^2=c^2[/tex]

In this equation, a and b are the legs and c is the hypotenuse.

x and 8.5 are the legs because they make up the right angle. 11.2 is the hypotenuse because it is opposite the right angle.

Substitute the values into the formula.

[tex]x^2+(8.5)^2=(11.2)^2[/tex]

Solve the exponents.

[tex]x^2+72.25 =125.44[/tex]

Solve for x by isolating the variable. 72.25 is being added, so we subtract 72.25 from both sides because subtraction is the inverse operation of addition.

[tex]x^2+72.25-72.25 = 125.44-72.25[/tex]

[tex]x^2=125.44-72.25[/tex]

[tex]x^2=53.19[/tex]

x is being squared, so we take the square root of both sides.

[tex]\sqrt{x^2}=\sqrt {53.19}[/tex]

[tex]x=\sqrt{53.19[/tex]

[tex]x=7.29314746869[/tex]
