Answer:

Step-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.

Answer:

The second choice, [tex](-1,\, 12)[/tex].

Step-by-step explanation:

Note, that the expression [tex]y = f(x)[/tex] is an equation. A point [tex](x,\, y)[/tex] is on the graph of [tex]y = f(x)\![/tex] if and only if the value of [tex]x[/tex] and [tex]y[/tex] satisfy this equation; that is: in other words, the [tex]y\![/tex]-coordinate of that point (the second number in the tuple) should be equal to [tex]f(x)[/tex], which is equal to [tex](-3\, x +9)[/tex] (evaluated where [tex]x\![/tex] is equal to the first number in the tuple.

For each tuple in the choices, calculate the value of [tex]f(x)[/tex] where [tex]x[/tex] is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on [tex]y = f(x)[/tex] only if these two numbers match.

To get the median of the ages given

2, 4, 5, 6, 7, 8, 8, 8, 0, 3, 5, 9, 1, 4, 7, 6, 1, 2, 4, 4, 8

First we will need to rearrange the median ages in ascending order (from lowest to highest)

0, 1, 1, 2, 2, 3, 4, 4, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8, 8, 9

Next is to locate the middle value of the arranged data

(0, 1, 1, 2, 2, 3, 4, 4, 4, 4), 5, (5, 6, 6, 7, 7, 8, 8, 8, 8, 9)

The total values in both parenthesis are the same(10 in numbers) leaving 5 as the middle number.

Hence the median age of the people in the pool is 5years

Answer:

The commission made is $104

Step-by-step explanation:

Here, given the payment analysis, we want to know the total pay for a day in which 12 demonstrations were made.

From the question, we can deduce the following;

For the first 7 demonstrations , $7 is paid

Now for the remaining 5 out of the total 12, the amount paid per demonstration is $11

So the total commission earned will be;

$7(7) + $11(5)

= $49 + $55 = $104

================================================

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.

Answer:

Step-by-step explanation:

Let the probability of winning from left side be L and from right side by R .

Let the probability of winning by king be K .

Given information can be summarised as follows :

P(L) = .6

P(R) = .75

P K/(L∩R)=.98

P K/(L∩R')= .8

P K/(L'∩R) = .5

P K/(L∩R)' = .2

Probability of win by King can be summarised as follows .

P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'

P(L∩R) = .6 X .75 = .45

P(L∪R) = P(L) +P(R) -  P(L∩R)

= .6 +.75 - .45 = .90

P(L∪R)' = 1 - P(L∪R) = .10

P(L∩R') = P(L)  - P(L∩R) = .6 - .45 = .15

P(L'∩R) = P(R) - P(L∩R) = .75 - .45 = .30

P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'

= .45  x .98 + .15 x .8 + .30 x .5 + .1 x .2

= .441 + .12 + .15 + .02

= .73 approx .  

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.

The graph of equation y=−3x+4 has been drawn below.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given a linear function y=−3x+4

In order to plot a graph, we need to assume one x value, and corresponding to that need to calculate the y value.

Lets say x = 0 than

y = -3(0) + 4

y = 4 ⇒ (0.4) will be the first coordinate of the line.

Now let's say y = 0 than

0 = -3x + 4

x = 1.33 ⇒ (1.33, 0) will be the second coordinate of the line.

So,

Draw a straight line by passing both points gives us an f the equation y=−3x+4.

The graph of the equation y = -3x + 4 is shown in the figure attached with the answer.

We have the following equation of a straight line y = - 3x + 4.

We have to plot the equation of this straight line.

The general equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question -

The equation of line = - 3x + 4

Now, comparing this line with the general equation of line -  y = mx + c, we get -

m = -3

c = 4

Hence, the graph of the equation is shown in the figure attached with the answer.

Answer:

(4,0)

Step-by-step explanation:

So we have the system of equations:

[tex]y=-2x+8\\y=x-4[/tex]

To solve, we can use substitution.

Substitute the second equation into the first. So:

[tex]x-4=-2x+8[/tex]

Add 2x to both sides. The right cancels:

[tex]3x-4=8[/tex]

Add 4 to both sides:

[tex]3x=12[/tex]

Divide both sides by 3:

[tex]x=4[/tex]

Now, let's substitute this back into the second equation to find y:

[tex]y=x-4[/tex]

Substitute 4 for x:

[tex]y=4-4[/tex]

Subtract:

[tex]y=0[/tex]

So, our solution is (4,0).

And we're done!

Steps to solve:

9b + 5 = 23

~Subtract 5 to both sides

9b = 18

~Divide 9 to both sides

b = 9

Answer:

0.006

Step-by-step explanation:

This is the answer because:

Short Way:

1) We know 3 x 2 is 6

2) When we multiply with zeros, how many ever zeros there are in the factors together, should be in the answer. In this case, in the answer we should have 3 zeros, one before the decimal point and two after the decimal point, because in 0.02 there are two zeros while in 0.3 there is only one zero.

3) Finally, the answer would be 0.006

Long Way:

1) You can do long multiplication to solve for the answer.

2) 0.02

   × 0.3

Is 0.006 because 3 x 2 is 6, and then 3 x 0 is 0 and then 3 x 0 is 0.

Answer:

$ 13,563.20

Step-by-step explanation:

Formula for total amount accrued or gathered after interest is compounded monthly = A = P(1 + r/n)^nt

A = Amount after t years

P = Initial amount Invested = $5,000

r = Interest rate = 5% = 0.05

n = compounding frequency = Every month = 12

t = time in years = 20

A = $5000(1 + 0.05/12)^20 × 12

A = $ 13,563.20

Therefore, Peyton will have $13,563.20 in the account after 20 years.

Answer:

FV = PV (1 + )nt

PV = $5,000

r = 0.05

n = 12

t = 20

FV = 5,000 (1 + )12 · 20

= 13,563

Answer:

Proportion of total delivered on time is 70% or 7/10

Step-by-step explanation:

Here, we want to know the proportion of all the packages delivered on time.

Moving away from the percentage, let’s say the total produced package amongst the 3 is 100

So;

Service A has 60% which is 60

Service B has 30% which is 30

Service C has 10% which is 10

Now from here, we move as follows;

on time rate for service A is 80%

This means 80/100 of the 60 is delivered on time

That will be 80/100 * 60 = 48

For service B, 60% is delivered on time; Thus we have ;

60/100 * 30 = 1800/100 = 18

For service C , 40% of 10

40/100 * 10 = 4

So the total on time delivery will be;

18 + 4+ 48 = 70

So the proportion delivered on time will be 70/100 = 7/10 or 70%

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.
