x+25

Answer:

Yes

Step-by-step explanation:

The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.

It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means  regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .

Therefore

(standard deviation/ √sample size)²= variance / n

2/ √20

= 2/4.472

=0.44721

The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n

Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n and this can be determined by finding the mean and standard deviation for the distribution of the sample means.

Given :

The mean for the distribution of the sample means is given by:

[tex]\mu_x = \mu[/tex]

[tex]\mu_x = 6.7[/tex]

The standard deviation for the distribution of the sample means is given by:

[tex]\rm \sigma_x = \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\sigma_x = \dfrac{2}{\sqrt{20} }[/tex]

[tex]\sigma_x = 0.44721[/tex]

Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n.

Answer:

The correct answer is X=5

I'm 10000000000% sure

Answer:

x = 5

Step-by-step explanation:

First, to get rid of the fraction, multiply both sides of the equation by x.

— (14.8/x + 2.4) * x = 5.36 * x

— 14.8 + 2.4x = 5.36x

Next, subtract 2.4x from both sides of the equation.

— 14.8 + 2.4x - 2.4x = 5.36x - 2.4x

— 14.8 = 2.96x

Now, divide both sides of the equation by 2.96.

— 14.8/2.96 = 2.96x/2.96

— 5 = x

Answer:

97.5% of American women have shoe sized less than 11.19

Step-by-step explanation:

Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19

The first thing we shall do here is to find the z-score

Mathematically, that will be calculated using the formula;

z = (x-mean)/SD

z = (11.19-8.15)/1.52

z = 2

We can see that the given value is 2 standard deviation away to the right of mean

So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule

So according to the empirical rule

The percentage will be

100-2.35-0.15

= 100-2.5 = 97.5%

Answer:

Step-by-step explanation:

Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}

AC = 4[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AC² + 9² = 17²

AC² + 81 = 289 ( subtract 81 from both sides )

AC² = 208 ( take the square root of both sides )

AC = [tex]\sqrt{208}[/tex] = 4[tex]\sqrt{13}[/tex] ← exact value

     ≈ 14.42 ( to 2 dec. places )

Answer:

54 one-third acre lots

Step-by-step explanation:

24 - 6 = 18

18 ÷ 1/3  =  18 × 3 = 54

Answer: 54

Step-by-step explanation:The remaining portion to be divided into 1/3 acre lots is the difference between the number of acres owned by the farmer and the number of arces used for the entrance. This difference is

= 24 arces - 6 arces

= 18 acres

These acres is to be divided into 1/3 arce then the number of 1/3 arce loits that will be available

= 18 ÷ 1/3

= 18 × 3/1

= 54
