Answer:

we get [tex]x^2=12-6\sqrt{3}[/tex]

Step-by-step explanation:

We are given: [tex]x=3-\sqrt{3}[/tex]

We need to find [tex]x^2[/tex]

Note: Since question is not clear, I am assuming that we need to find [tex]x^2[/tex]

Solving:

[tex]x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\[/tex]

We know that [tex](a-b)^2= a^2-2ab+b^2[/tex]

Using formula and simplifying

[tex]x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\[/tex]

So, we get [tex]x^2=12-6\sqrt{3}[/tex]

Answer:

The value is  [tex]n =2401  [/tex]

Step-by-step explanation:

From the question we are told that  

 The  margin of error is  E = 2%= 0.02

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Here we are going to assume that the sample proportion is  [tex]\^ p = 0.50[/tex]

  Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>   [tex]n =[\frac{ 1.96 }{ 0.02} ]^2 * 0.5 (1 -0.5  ) [/tex]

=>    [tex]n =2401  [/tex]

Step-by-step explanation:

Step-by-step explanation:

The correct answer is: Point B.

The easiest way to solve this is to make the fraction, 3/5, to a decimal.

3/5 = 0.6

Since point B is the closest estimate to 0.6 on the number line, we can confirm that Point B represents 3/5.

Answer:

P(X is less than 348) = 0.2148

Step-by-step explanation:

Given that:

Sample proportion (p) = 0.3

Sample size = 1200

Let X be the random variable that obeys a binomial distribution. Then;

[tex]X \sim Bin(n = 1200,p =0.3)[/tex]

The Binomial can be approximated to normal with:

[tex]\mu = np = 1200 \times 0.3 \\ \\ \mu= 360[/tex]

[tex]\sigma = \sqrt{np(1-p) } \\ \\ \sigma = \sqrt{1200 \times (0.3)(1-0.3) } \\ \\ \sigma = 15.875[/tex]

To find:

P(X< 348)

So far we are approximating a discrete Binomial distribution using the continuous normal distribution. 348 lies between 347.5 and 348.5

Normal distribution:

x = 347.5, [tex]\mu[/tex] = 360, [tex]\sigma[/tex] = 15.875

Using the z test statistics;

[tex]z = \dfrac{x - \mu}{\sigma}[/tex]

[tex]z = \dfrac{347.5 - 360}{15.875}[/tex]

[tex]z = \dfrac{-12.50}{15.875}[/tex]

z = -0.7874

z ≅ - 0.79

The p-value for P(X<347.5) = P(Z < -0.79)

From the z tables;

P(X<347.5) = 0.2148

Thus;

P(X is less than 348) = 0.2148

Answer:

i dont see the question

Step-by-step explanation:

Complete question is;

In a study investigating a link between walking and improved​ health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.

Specify the null and alternative hypotheses for testing whether the true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes

Answer:

Null Hypothesis: H0: μ = 873

Alternative hypothesis: Ha: μ < 873

Step-by-step explanation:

From the study, the claim is that the true average number of minutes gotten from the population average in the past month that the adults had walked for the purpose of health or recreation is lower than the average of 873 minutes.

Now, the population study says it's equal to 873 minutes.

Thus, the hypotheses can be written as;

Null Hypothesis: H0: μ = 873

Alternative hypothesis: Ha: μ < 873

Answer:

1,102

Step-by-step explanation

406/7=56 (unit rate)

56*19=1102

Answer:

The answer is 1,102

Step-by-step explanation:

First, we need to figure out how much per hour.

406 divided by 7 = 58

Now we multiply by the hours

58 x 19 = 1,102

Answer:

5

Step-by-step explanation:

∆FGH is similar to ∆JKH. Therefore, their corresponding lengths are proportional to one another. Thus:

[tex] \frac{GH}{KH} = \frac{FH}{JH} [/tex]

GH = x + 15

KH = x

FH = 12 + 4 = 16

JH = 4

Plug in the values

[tex] \frac{x + 15}{x} = \frac{16}{4} [/tex]

Cross multiply

[tex] (x + 15) \times 4 = 16 \times x [/tex]

[tex] 4x + 60 = 16x [/tex]

Subtract 4x from each side

[tex] 60 = 16x - 4x [/tex]

[tex] 60 = 12x [/tex]

Divide both sides by 12

x = 5

KH = x = 5

Answer:

ANY line that has a slope of 3, and any y intercept other than -5.

Step-by-step explanation:

Parallel lines have the same slopes, but different y intercepts.

So, it would be ANY line that has a slope of 3, and any y intercept other than -5.

Answer:

t=4

Step-by-step explanation:

4t-2=14

You then add 2 to both sides and get

4t=16

Then you must divide 16 by 4 and get

t=4

The solution of the linear equation 4t - 2 = 14 will be 4.

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

The equation is given below.

4t - 2 = 14

The degree of the equation is one, so the equation will be a linear equation. Then solve the equation for 't', then we have

4t - 2 = 14

4t = 16

t = 16 / 4

t = 4

The solution of the linear equation 4t - 2 = 14 will be 4.
