Answer:

The 95% CI is   \(2.108 < \mu < 2.892\)

Step-by-step explanation:

From the question we are told that

   The  population mean \(\mu = 2.5\)

    The standard deviation is  \(\sigma = 0.8\)

Given that the confidence level is  95% then the level of confidence is mathematically evaluated as

          \(\alpha = 100 - 95\)

   =>  \(\alpha = 5\%\)

  =>    \(\alpha = 0.05\)

Next we obtain the critical value of  \(\frac{\alpha }{2}\) from the normal distribution table, the values is  \(Z_{\frac{\alpha }{2} } = 1.96\)

Generally the margin of error is mathematically evaluated as

          \(E = Z_{\frac{\alpha }{2} } * \frac{\sigma}{\sqrt{n} }\)

here we would assume that the sample size is  n =  16 since the person that posted the question did not include the sample size

  So    

               \(E = 1.96* \frac{0.8}{\sqrt{16} }\)

               \(E = 0.392\)

The  95% CI is mathematically represented as

              \(\= x -E < \mu < \= x +E\)

substituting values

              \(2.5 - 0.392 < \mu < 2.5 + 0.392\)

substituting values

              \(2.108 < \mu < 2.892\)

The representations of the inequality is  an open circle is at 1 and a bold line starts at 1 and is pointing to the right.

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g. 5 < 6, x ≥ 2, etc.

Since our answer is x > 1.  An open circle will be at 1 and a bold line starts at 1 and is pointing to the right (>). Check the attached image.

Step-by-step explanation:

Express \(\sf0.\overline{36}\) in p/q form

\(\large\underline{\sf{Solution-}}\)

Given that:

\(\longmapsto\sf0.\overline{36}\)

Let this be equal to x.

So,

\(\longmapsto\sf x=0.\overline{36}- - - -(1)\)

Multiplying both side by 100,

\(\longmapsto\sf 100x=36.\overline{36}- - - -(2)\)

Subtracting (2) from (1),

\(\longmapsto\sf 100x-x=36.\overline{36}-0.\overline{36}\)

\(\longmapsto\sf 99x=36\)

So,

\(\longmapsto\sf x=\dfrac{36}{99}\)

Dividing by 9,

\(\sf\longmapsto x=\dfrac{4}{11}\)

Hence,

\(\sf\longmapsto\bf0.\overline{36}=\dfrac{4}{11}\)

Step-by-step explanation:

As my previous answer got deleted for being wrong (in which it was right), I will answer again.

The answer is 1. Why? Just plug it into the equation. F(1) = 2(1) + 5 = 7.

This is proof that it is right, and that there are some corrupt admins on brainly.

How to get to this solution?

Well notice how we are given what f(a) is. It is 2a + 5. So plug this in for f(a).

If we do so, we get 2a + 5 = 7.

Solving this equation, we get a = 1.

7π/12 lies in the second quadrant, so we expect cos(7π/12) to be negative.

Recall that

\(\cos^2x=\dfrac{1+\cos(2x)}2\)

which tells us

\(\cos\left(\dfrac{7\pi}{12}\right)=-\sqrt{\dfrac{1+\cos\left(\frac{7\pi}6\right)}2}\)

Now,

\(\cos\left(\dfrac{7\pi}6\right)=-\cos\left(\dfrac\pi6\right)=-\dfrac{\sqrt3}2\)

and so

\(\cos\left(\dfrac{7\pi}{12}\right)=-\sqrt{\dfrac{1-\frac{\sqrt3}2}2}=\boxed{-\dfrac{\sqrt{2-\sqrt3}}2}\)

The probability that an 18-year-old man picked at random is taller than 74 inches is approximately 0.0228 or 2.28%.

We have,

We can use the standard normal distribution to solve this problem by standardizing the height value using the formula:

z = (x - μ) / σ

where:

x = the height value (in inches)

μ = the mean height (in inches)

σ = the standard deviation (in inches)

Substituting the given values, we get:

z = (74 - 68) / 3

z = 2.0

Using a standard normal table or calculator, we can find the probability that a random standard normal variable is greater than 2.0 to be approximately 0.0228.

Therefore,

The probability that an 18-year-old man picked at random is taller than 74 inches is approximately 0.0228 or 2.28%.

Step-by-step explanation:

a prime polynomial is one which does not factor into 2 binomials.

its only factors are 1 and itself

attempt to factorise the given polynomials

3x³ + 3x² - 2x - 2 ( factor the first/second and third/fourth terms )

= 3x²(x + 1) - 2(x + 1) ← factor out common factor (x + 1) from each term

= (x + 1)(3x² - 2) ← in factored form

--------------------------------------------------

3x³ - 2x² + 3x - 4 ( factor the first/second terms

= x²(3x - 2) + 3x - 4 ← 3x - 4 cannot be factored

thus this polynomial is prime

----------------------------------------------------

4x³ + 2x² + 6x + 3 ( factor first/second and third/fourth terms )

= 2x²(2x + 1) + 3(2x + 1) ← factor out common factor (2x + 1) from each term

= (2x + 1)(2x² + 3) ← in factored form

-------------------------------------------------

4x³ + 4x² - 3x - 3 ( factor first/second and third/fourth terms )

= 4x²(x + 1) - 3(x + 1) ← factor out common factor (x + 1) from each term

= (x + 1)(4x² - 3) ← in factored form

--------------------------------------------------

the only polynomial which does not factorise is

3x³ - 2x² + 3x - 4

Step-by-step explanation:

I assume the length that got cut off is 18.

The domain for the function is the interval [0, 14], which represents the feasible values for the length of one side of the rectangular garden.

To determine the appropriate values of the domain for the graph of the function \(A(t) = -t^2 + 14t\), we need to consider the situation and the constraints given.

The function A(t) represents the area of the rectangular garden as a function of the length of one of its sides, which is denoted by t.

We are also told that Marama plans to fence the garden with 28 feet of wired fencing.

Now, let's break down the problem and find the appropriate values for the domain.

We know that the perimeter of a rectangle is the sum of all its sides. In this case, since we have a rectangular garden, the perimeter can be represented as:

\(Perimeter = 2t + 2w\),

where t is the length of one side (the width) and w is the length of the other side (the width).

The problem states that Marama plans to use 28 feet of wired fencing. Therefore, the perimeter of the garden must equal 28 feet:

\(2t + 2w = 28\).

Simplifying this equation, we have:

\(t + w = 14\).

We can express w in terms of t as \(w = 14 - t\).

The area of a rectangle is given by the product of its length and width:

\(Area = t \times w\).

Substituting the expression for w from step 2, we have:

\(A(t) = t \times (14 - t)\).

Simplifying further:

\(A(t) = 14t - t^2\).

To determine the appropriate values of the domain, we need to consider the context of the problem. Since we are dealing with a physical garden, both the length and width must be positive numbers. Additionally, the values of t must be feasible given the constraints of the perimeter.

We know that \(t + w = 14\), so \(t + (14 - t) = 14\), which simplifies to \(14 = 14\).

This shows that the value of t can range from 0 to 14, inclusive.

Therefore, the appropriate values of the domain for the graph of the function \(A(t) = -t^2 + 14t\) are \(t \epsilon [0, 14]\).

To illustrate this graphically, we can plot the function \(A(t) = -t^2 + 14t\) and mark the appropriate values of the domain on the x-axis (representing t):

Answer:e. The sampling distribution of the difference in sample proportion is approximately normal.

Step-by-step explanation:

(200) (0.06) >= 10

(200) (0.94) >=10

(197)(0.086) >=10

(197)(0.914) >= 10

We test the sample proportions of it is normal :

Deer population 1:

Sample size, n1 = 200

Proportion, p1 = 0.06

q = 1 - p = 1 - 0.06 = 0.94

n1 * p = 200 * 0.06 = 12

n1 * q = 200 * 0.94 = 188

Deer population 2:

Sample size, n2 = 197

Proportion, p = 0.086

q = 1 - p = 1 - 0.086 = 0.914

n2 * p = 197 * 0.086 = 16.94

n2 * q = 197 * 0.914 = 180.06

Since for samples and proportions ;

n*p and nq ≥ 10 ;

We cm conclude that the sampling distribution of the difference in sample mean is appropriately normal.

The sampling distribution of the difference in sample proportions is approximately normal because samples and proportions are greater than or equal to 10.

Given :

For dear population 1, the sample size is 200 and proportion is 0.06.

\(\rm q_1 = 1-p_1=1-0.06=0.94\)

\(\rm n_1p_1=200\times 0.06=12\\\)

\(\rm n_1q_1=200\times 0.94 = 188\)

Now, for dear population 2, the sample size is 197 and the proportion is 0.086.

\(\rm q_2 = 1-p_2=1-0.086=0.914\)

\(\rm n_2p_2=197\times 0.086=16.94\)

\(\rm n_2q_2=197\times 0.914 = 180.06\)

Therefore, from the above calculations, it can be concluded that the sampling distribution of the difference in sample proportions is approximately normal because samples and proportions are greater than or equal to 10.
