A simple random sample of size n is drawn from a normally distributed population, and the mean of the sample is x Overbar, while the standard deviation is s. What is the 99% confidence interval for the population mean? Use the table below to help you answer the question. Confidence Level 90% 95% 99% z*-score 1. 645 1. 96 2. 58.
Using the z-distribution, as we have the standard deviation for the population, it is found that the 99% confidence interval for the population mean is given by:
[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.s is the standard deviation for the population.99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.58[/tex].
The other parameters are symbolic, hence the interval is given by:
[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]

1. A car is traveling down a road at a constant speed of 50 miles per hour. a. Complete the table with the amounts of time it takes the car to travel certain distances, or the distances traveled for certain amounts of time. Help please and thank you :)
By finding the linear equation that relates distance and time, we can see that the complete table is:
time (hours) distance (miles)
2 100
1.5 75
t (50)*t
1 50
6 300
d/(50) d
How to complete the table?
After a small online search, I've found that the table is:
time (hours) distance (miles)
2
1.5
t
50
300
d
Now, remember the relation:
distance = speed*time.
In this case, we know that the speed is 50 mi/h, so if we define d as the distance and t as the time, we can write:
d = (50mi/h)*t
To complete the table, we just replace the value that appears in the table, and then we solve the equation for the other variable.
First we have t = 2 hours:
d = (50 mi/h)*2h = 100 mi
Then we have t = 1.5 hours
d = (50 mi/h)*1.5 h = 75 mi
Then we assume that we evaluate in t, so there we just write the equation:
d = (50 mi/h)*t
Now we go to the other side of the table, now we evaluate d, so we can write:
t = d/(50 mi/h)
(that is what goes in the table when we need to evaluate in d).
Then the fourth place in the table has d = 50 mi, replacing that:
t = (50mi)/(50 mi/h) = 1h
And finally, we evaluate in d = 300mi
t = (300 mi)/(50 mi/h) = 6h
Then the complete table is just:
time (hours) distance (miles)
2 100
1.5 75
t (50)*t
1 50
6 300
d/(50) d

if the width of a rectangle with perimeter P is 6 units , what is the length.
Answer:
L= P/2 - 6
Step-by-step explanation:
As you know that the Perimeter of a Rectangle = 2(L+W)
since Perimeter = P and Width = 6
Then P = 2(L+6)
Expanding
P=2L+12 --> 2L=P-12
Then L=(P-12)/2=P/2-6
The perimeter is twice the sum of width and length. Then the length of the rectangle is P/2 – 6 units.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
If the width of a rectangle with perimeter P is 6 units.
Perimeter = P
Width = 6 units
Then the length of the rectangle will be
Perimeter = 2 (Width + Length)
P = 2 (6 + L)
L = P/2 – 6
The length of the rectangle is P/2 – 6 units.

Construct an augmented matrix for this linear system: x − y − 4z = 5 2x 2z = 0 4x y z = 3.
The augmented matrix is,
[tex]\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)[/tex]
We have given system of linear equation is,
[tex]x - y - 4z = 5,2x + 2z = 0 ,4x +y +z = 3.[/tex]
What is the meaning of augmented matrix?In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is
[tex]1\ -1\ -4\ 5[/tex]
the second row is
[tex]2\ 0\ 2\ 0[/tex]
and the third row is

First, notice how the partially shaded squares fit perfectly into one another (the squares are perfectly cut from corner to corner). Once you match these squares to one another, you can then figure out that they add up to three full squares.
Secondly, measure how many squares there will be in the diagram after adding up the partial squares (resulting in a total of 15).
Finally, calculate the area of one of the squares (2cm x 2cm), which results in 4cm². As you have 15 total squares, multiply 4cm² by that to get the final answer of 60cm².

You are creating strings picking letters from the English alphabet at random. What is the probability that your randomly created string of length 11 will contain exactly 7 A's
There are 4 positions in the string that each have 25 choices (any letter in the English alphabet except A) and the other positions are filled with A, so there are 25⁴ possible strings containing exactly 7 A's.
Overall, there are 26¹¹ possible strings of length 11.
Then the probability of randomly generating a string containing exactly 7 A's is
25⁴ / 26¹¹ ≈ 0.000000000106427

Answer:
x = 6
Step-by-step explanation:
using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = 12 ( divide both sides by 2 )
