The 90% confidence interval is given by (3.9911; 7.9911)

It is 90% confident that the true average speed of a vehicle on a highway is between 3.9911 and 7.9911 miles per hour.

1) Former concept

A confidence interval is "a range of values ​​that is likely to encompass the values ​​of a population with some degree of confidence. Often expressed as a percentage.

The error bar is the range of values ​​above and below the sample statistic in the confidence interval.

A probability distribution that is symmetric about the mean and indicates that data close to the mean are more common than data far from the mean.

X = 2, represents the sample mean of the sample

μ = population mean (variable of interest)

s = 1 represents the standard deviation of the sample

n = 11 represents the sample size

2 ) Confidence Interval:

Confidence Interval for mean is given below:

                  X ± t (α/2) s/√n

To compute the critical value, we first need to find the degrees of freedom given by

df = n -1

   = 11 -1 = 10

Confidence is 0.90 or 90%, so the value of and is α = 0.1 , and α/2 = 0.05 you can use Excel, a calculator, or a spreadsheet to find the critical values. The Excel command would be "=-T.INV(0.05,10)".

2 - 1.81 (1/√11) = 3.9911

2 + 1.81 (1/√11) = 7.9911

So in this case the 90% confidence interval is (3.9911 , 7.9911)

We are 90% confident that the true mean for the speeds of vehicles traveling on a highway is between 3.9911 and 7.9911 miles per hour.

This is a fraction, so it can also be written as a decimal by dividing the numerator by the denominator: 1/62 = 0.0161.

What is conditional probability?

Conditional probability is a measure of the probability of an event occurring given that another event has already occurred. It is written as P(A|B), where A and B are events and P(A|B) represents the probability of event A occurring given that event B has already occurred.

To find the probability that one of each color is drawn from the bag, you can use the following steps:

Calculate the total number of possible combinations of three balls that can be drawn from the bag without replacement. This is equal to the number of ways to choose 3 balls from a total of 16 balls, which is calculated using the combination formula:

Total number of combinations = 16 choose 3

= (16 * 15 * 14) / (3 * 2 * 1)

= 560

Calculate the number of combinations that include one ball of each color. There are 3 ways to choose the red ball, 3 ways to choose the black ball (since one of each color has already been chosen), and 1 way to choose the white ball (since there is only 1 white ball left). Therefore, the total number of combinations that include one ball of each color is:

Combinations with one ball of each color = 3 * 3 * 1

= 9

Calculate the probability by dividing the number of combinations with one ball of each color by the total number of combinations:

Probability = 9 combinations / 560 combinations

= 9/560

= 1/62

Therefore, the probability that one of each color is drawn from the bag is 1/62. This is a fraction, so it can also be written as a decimal by dividing the numerator by the denominator: 1/62 = 0.0161.

The lengths of the edges of the considered rectangular box which will give the minimum surface area are all ∛34.

How to find the surface area and volume of a closed rectangular box?

Suppose the dimensions of the rectangular box be 'a', 'b' and 'c' units respectively. Then, we get:

Surface area of the box, S = 2(ab + bc + ca) unit²

Volume of the box, V = abc unit³

For the considered box, let the dimensions be 'a', 'b' and 'c' cm.

Then, as we're provided that the volume of the box is 34 cubic cm, we get:

abc = 34

c = 34/ab

Thus, the surface area of the considered figure would be given as:

S = 2(ab + bc + ca) unit²

S = 2(ab+ c(b+a))

= 2(ab+ (34/ab) (b+a))

=( 2a²b² + 68b + 68a)/ ab cm²

There is symmetry in the equation we obtained for surface area between 'a' and 'b'.

That means, they will be of same measure to minimize or maximize the surface area. It is because if one of them is bigger than other, it is possible to prove that other one, by same tricks, can be proved bigger than first one.

Thus, we have a = b for S to be maximum or minimum.

Thus, we get:

Smax or min = (2a⁴+136a) / a²

= (2a²+ 136) / a

= f(a)

Taking first derivative of f(a), we get:

f'(a) = 4a - 136 / a²

f''(a) = 4 + 272/a³

Putting second rate = 0, we get critical points as:

f'(a) = 0

4a = 136/ a²

a³ = 34

a = ∛34 = b

Thus, the only critical value found is corresponding to minima.

Thus, S is minimum when a = b = ∛34

The value of c is:

c = 34/ab

= 34/ [tex]\sqrt[3]{34^{2} }[/tex]

= (34)¹/³

c = ∛34

Thus, the lengths of the edges of the considered rectangular box which will give the minimum surface area are all ∛34.

The population means may be the same

So, option D is correct.

In statistics, the probability that a population parameter will fall between a set of values a predefined percentage of the time is known as the confidence interval. Analysts typically use confidence intervals that cover 95% or 99% of the expected observations while assessing data. In frequentist statistics, an estimation range for an unknown parameter is referred to as a confidence interval. The most common confidence level for computing confidence intervals is 95%, however other levels, such 90% or 99%, are also occasionally employed. The conclusion is reached that the result is statistically significant if the confidence interval eliminates the value of zero effect.

If (μ₁- μ₂=0) is included in the confidence interval, that means this two means have the same difference that is zero.

The remaining root of f(x) will be 3 - [tex]\sqrt{11}[/tex]

To answer this question we have to find the conjugate of 3+[tex]\sqrt{11}[/tex],

For example, the conjugate of p+q will be p-q or vice versa.

Let us consider x= 2+[tex]\sqrt{11}[/tex]

To simplify the equation let us subtract 3 on both sides of the equation

x - 3 = 3+[tex]\sqrt{11}[/tex] - 3

x - 3 = [tex]\sqrt{11}[/tex]

Square both,

[tex](x - 3)^{2}[/tex] = 11

[tex](x - 3)^{2}[/tex] - 11 =0

Now we will use the principle of Square difference to factorize both sides-

[tex](d^{2} - e^{2}) = (d - e)(d + e)[/tex]

(x - 3) - 11 × (x - 3) + 11 = 0

on solving the equation we get,

(x - 3) - 1 = 0  let us consider this first equation

or (x - 3) + 11 = 0 let us consider this second equation

Add [tex]\sqrt{11}[/tex] on both sides of the first equation,

[tex]x - 3 = \sqrt{11}[/tex]

Subtract [tex]\sqrt{11}[/tex] on both sides of the second equation,

[tex]x - 3 = -\sqrt{11}[/tex]

What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the figure be a square

Now , the sides of the square ABCD is AB , BC , CD and DC

The square ABCD is reflected about the side BC

So , the possible relations are

The reflected square will be A'B'C'D'

Step-by-step explanation:

The slope of the line given by the equation 3x - 8y = -16 is 3/8.

To find the slope of the line given by the equation 3x - 8y = -16, we need to rearrange the equation into slope-intercept form, y = mx + b, where m represents the slope.

Starting with the given equation:

3x - 8y = -16

We can isolate y by subtracting 3x from both sides:

-8y = -3x - 16

Next, we divide both sides of the equation by -8 to solve for y:

y = (3/8)x + 2

Now, we can observe that the equation is in slope-intercept form, y = mx + b, with m = 3/8.

This means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 3/8.
