Solve for x. Round your answer to the nearest tenth if necessary. NO SCAMS OR LINKS PLEASE!!!!!! ANSWER IS NOT 14.1 ​

Answers

Answer:

[tex]\boxed {\boxed {\sf x\approx 7.3}}[/tex]

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.

a= xb=8.5 c=11.2

Substitute the values into the formula.

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

Solve the exponents.

(8.5)²= 8.5*8.5= 72.25 (11.2)²= 11.2*11.2= 125.44

[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]

Round to the nearest tenth. The 9 in the hundredth place tells us to round the 2 up to a 3.

[tex]x \approx 7.3[/tex]

The unknown side, x, is approximately 7.3

A population has a standard deviation x=18.4. How large a sample must be drawn so that a 98% confidence interval will have a margin of error equal to 4.1?

Answers

Answer:

"109" will be the appropriate response.

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]

⇒      [tex]=(10.4386341)^2[/tex]

⇒      [tex]=109[/tex]

Answers

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

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

What is expected value?

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.

ApplicationStep 1: Define

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

We are given a graph of a function.

Step 2: Solve

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.

Answer

∴ the answer to the question is equal to:

A. D: x ≥ 3

    R: y ≥ 1

The unit rate of flavor B is; $0.20 per ounce

An equation to help Ray determine how many red balloons are needed compared to the the total number of balloons used is; y = ²/₅x

How to find the unit rate?

A unit rate is also called unit ratio and it describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.

We are given that Flavor A is 20 ounces and costs $4.49. Thus;

Unit rate of flavour A = $4.49/20 = $0.2245 per ounce

For Flavor B, the equation y = 0.20x represents the cost (y) per ounce (x) in each box. Thus, the unit rate is $0.20 per ounce

Since ray is making bouquets of balloons. In each bouquet 2 out of every 5 balloons are red.

If x is the number of ounces, then the unit rate is 2/5 . Thus, the equation is; y = ²/₅x

If $x$ is a positive multiple of 8 and $x^2>100$, but $x<20$, what is $x$?

Answers

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, $x=\boxed{16}$.
