A paper sheet is cut 28 inches to the nearest inches. Find the maximum and minimum length of the patient possible.
Answer:
max: 28.5 inchesmin: 27.5 inchesStep-by-step explanation:
If the actual dimension were different from 28 inches by more than 1/2 inch, it would be reported as a different dimension. So, the minimum that will be reported as 28 is 27.5. The maximum that will be reported as 28 will be 28.4999999.... ≈ 28.5
The maximum and minimum length of the sheet are 28.5 inches and 27.5 inches, respectively.

State the requirements to perform a goodness of Fit test. Choose the correct answer below:
A. at least 80% of expected frequencies > 5
B. all expected frequencies > 5
C. at least 90% of expected frequencies > 5
D. at least 90% of expected frequencies >10 a
E. t least 80% of expected frequencies > 10
F. all expected frequencies > 1
Answer:
B. all expected frequencies > 5
Step-by-step explanation:
The expected number np(i) in any of the classes or cells should not be less than 5. So when the expected number np(i) in any class is less than 5 , we may combine this class with one or more other classes to meet this requirement.
It is clear that chi square will be small when all ni are close to their expected values npi. The chi square will become larger when the difference becomes larger. The chi square thus measures the amount of deviation ( or agreement ) between the observed and expected results.
Thus it is a good approximation if all the expected values npi are sufficiently large and hence chi square distribution confirms with the ( k-1) degrees of freedom.

PLEASE HELP!!!What are the possible rational roots of 2x^2-10x+8 according to the rational root theorem? (1 point)
[tex]\pm 8, \pm 4, \pm 2, \pm 1, \pm \frac{1}{2}[/tex]
================================================
Explanation:
The first coefficient is 2. The last term is 8.
To find the possible rational roots, we look at factors of 2 and 8
factors of 2 = 1, 2
factors of 8 = 1,2,4,8
Then you divide each factor of 8 over the factor of 2. More generally, we divide the factors of the last term over the factors of the first coefficient.
A table is recommended so you can keep everything organized. See the diagram below.
The table shows 8, 4, 2, 1 and 1/2 as the unique results in each cell.
The table only shows the positive results, but the negative results will basically be identical except for the negative sign of course. The plus minus is to account for things like saying "-2 is a factor of 8 since -2*(-4) = 8". I find its easier to just focus on the positive and then stick plus minus at the end when all is said and done.
This is why choice B is the answer.
-----------
Extra info:
Keep in mind this list is the possible rational roots and it does not mean they are all actual rational roots of the given polynomial. You'll need to plug each one into the polynomial to see if you get 0 as an output.
For instance, plugging x = 2 into y = 2x^2-10x+8 leads to y = -4 showing that x = 2 is not a root; however, x = 1 is a root because plugging x = 1 into y = 2x^2-10x+8 leads to y = 0. There's one other rational root for this polynomial.

yesterdays world cup final had a viewing figures of 138,695,157. what is the value of the 3?
Answer:
The number is 138,695,157.
If you want to know the value of a particular number, then follow the steps:
1) Start at the decimal point (in the right) and count the places until you reach the desired number.
For example, the 3 is in the 8th position, so here we take n = 8.
2) Now that you find n, multiply your number by 10^(n-1)
in this case we have:
3*10^(8 - 1) = 3*10^7 → (this means that you add 7 zeros at the right of the 3)
3*10^7 = 30,000,000
So that is the value of the 3 in the given number. (3 ten-millions)

The ratio of a circle radius to its diameter is always 1 to 2. In math class, Russell uses his compass to draw a circle with a radius of 6 centimeters. What is the diameter of the circle Russell drew?
Answer:
The diameter is 12
Step-by-step explanation:
Since it is 1 to 2
The diameter is double the radius.
The radius is 6 and 6 times 2 is 12.
The diameter of the circle Russell drew is 12 centimeters.
A circle is a bounded figure with a point from the center to its circumference is equidistant.
A diameter is a straight line from one point on the circumference of the circle to another point on the circumference of the circle.
Radius is a line from the center of the circle to the circumference of the circle.
The ratio of radius to the diameter is 1 : 2. This means that the diameter is two times the length of the radius. If the radius is 6cm, the diameter = 6 x 2 = 12 cm.

Point C is located at (2,8). If it is reflected across the x axis, where will C be located?
Answer:
(2, -8)
Step-by-step explanation:
The answer is (2, -8) because when you reflect a point across the x-axis, the x-coordinate always remains the same, but the y-coordinate will change. In other words, the y-coordinate becomes the opposite (signs change). In this case, since the y-coordinate was positive 8, when you reflect the point across the x-axis, the y-coordinate will change to -8

A college dormitory houses 200 students. Those who watch an hour or more of television on any day always watch for less than an hour the next day. One-fourth of those who watch television for less than an hour one day will watch an hour or more the next day. Half of the students watched television for an hour or more today. How many will watch television for an hour or more tomorrow, in 2 days, and in 40 days
Answer:
Tomorrow = 25 students
In 2 days = 44 students
In 40 days = 40 students
Step-by-step explanation:
Let A = watch more than an hour
B = watch less than an hour
First of all we need to make a transition matrix
[tex]P = \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix} \binom{A}{B}[/tex]
Also we are given,
X = [100, 100]
A B
Therefore,
[tex]XP=\begin{bmatrix}100 & 100\end{bmatrix} \times \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix}[/tex]
= [25, 175]
Thus, 25 students will watch television for an hour or more tomorrow.
Now for 2 days,
[tex]XP^2=\begin{bmatrix}100 & 100\end{bmatrix} \times \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix} \times \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix}[/tex]
= [43.75, 156.25]
Hence, 44 students will watch television for an hour or more in 2 days.
Now in 40 days,
[tex]XP^40=\begin{bmatrix}100 & 100\end{bmatrix} \times \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix}^{40}[/tex]
But instead of multiplying the above matrix 40 times, we can we can find the long term division method.
Let
x = long term distribution of students watching television >1 hour
y = long term distribution of students watching television <1 hour
Therefore,
[tex]\begin{bmatrix}x & y\end{bmatrix} \times \begin{bmatrix}0 & 1\\ 0.25 & 0.75\end{bmatrix} = \begin{bmatrix}x & y\end{bmatrix}[/tex]
⇒ 0.25 y = x
And we know that x + y = 200
∴ 0.25 y + y = 200
∴ y = 160
And x = 40 ( ∵ x + y = 200)
Thus 40 students will watch televisions in the 40 days for an hour or more.

Turner treated his sister to lunch while visiting her in springdale. their lunch cost $400. and the sales tax in springdale is 11% if turner left an 18% tip on the $400, how much in total did he pay
Answer:
$516
Step-by-step explanation:
Price of lunch: $400
Sales tax: 11% of $400
Tip: 18% of $400
The sales tax and tip combined were 29% of $400 since 11% of $400 + 18% of $400 = 29% of $400.
We calculate the combined sales tax and tip:
29% of $400 =
= 0.29 * $400
= $116
The combined sales tax and tip were $116.
Now we add the combined sales tax and tip to the $400 price of dinner.
total = $400 + $116
total = $516

Rearrange the equation to isolate a . (a+bc)(d−e)=f
Answer:
a = cf - b(d-e)
c(d-e)
Step-by-step explanation:
Kindly check correct question as attached!
Solution
(a+b/c)(d-e) = f
a + b/c = f/d-e
a = [f/d-e] - [b/c]
Lcm = c(d-e)
a = cf - b(d-e)
c(d-e)
The equivalent value of the expression is a = [ f / ( d - e ) ] - ( b/c )
Given data ,
Let the equation be represented as A
Now , the value of A is
( a + b/c ) ( d - e ) = f
On simplifying the equation , we get
( a + b/c ) ( d - e ) = f
So , the left hand side of the equation is equated to the right hand side by the value of f
Divide by ( d - e ) on both sides , we get
a + b/c = f / ( d - e )
Subtracting b/c on both sides , we get
a = [ f / ( d - e ) ] - ( b/c )
a = [ f / ( d - e ) ] - ( b/c )
Therefore , the value of a = [ f / ( d - e ) ] - ( b/c )
Hence , the expression is a = [ f / ( d - e ) ] - ( b/c )
