The possible arrangement is 3960.

Permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.

Given that, Bart wants to plant 8 trees in a row along his fence.

Possible arrangement of 4 birches = 5 x 4 x 3 x 2 x 1 = 120

If 3 birches are next to each other, therefore, 6 possible arrangement are possible = A₄⁴ x A₅² = 480

Similarly,

If 2 birches are next to each other, therefore, 6 possible arrangement are possible = A₄⁴ x A₅² = 480

If 4 birches are not next to each other, therefore, possible arrangement are possible = A₄⁴ x A₅⁴ = 2880

Therefore, total arrangements = 120+480+480+2880 = 3960

Hence, the possible arrangement is 3960.

The answer is x(2-5x).

In factorization, you just need to identify the common factors and accordingly solve as per your requirement!

To factor the expression 2x-5x^(2) completely, we need to find the greatest common factor (GCF) of the two terms and factor it out. The GCF of 2x and 5x^(2) is x. So we can factor it out of the expression:

2x-5x^(2) = x(2-5x)

Now, the expression is factored in completely. The final answer is:

x(2-5x)

Therefore, factoring the expression 2x-5x^(2) gives the answer x(2-5x).

Answer:

Step-by-step explanation:

Dang, they made this a little harder. Now we need to actually calculate a slope. Good thing is, it's relatively easy. Slope is basically the rate of change, or the rise of the function over the run, which is shown as:

Δy/Δx

We can use two points to find the slope. I will use (2,795) and (4,1525)

(y1 - y2) / (x2 - x1)

(1525 - 795) / (4 - 2)

730 / 2

365

This is our slope, 365x.

Now we need the y-intercept, which is where the line hits the y-axis. It seems to be at 100, so the new equation is:

y = 365x + 100

If we want to know how many followers Lauren will have in 2018, we just use 7 for x years after 2011, since 2018 is 7 after 2011.

y = 365(7) + 100

y = 2555 + 100

y = 2655

Lauren has 2655 followers in 2018.

Answer:

See below.

Step-by-step explanation:

We are asked to solve this expression.

We should first identify that (-5) will be a positive 5 due to 2 negatives cancelling each other out.

We should have;

[tex]-2 \frac{1}{3}+5[/tex]

To make adding a bit more simpler for this type of problem, we should turn both values into Improper Fractions.

Improper Fractions are 2 or more fractions that have a greater numerator than a denominator. You can see why they're called improper.

Good Examples:

[tex]\frac{4}{3} \ and \ \frac{3}{2} \\4 > 3\\ 3 > 2[/tex]

Bad Examples:

[tex]\frac{3}{4} \ and \ \frac{4}{4} \\3 < 4\\4 = 4[/tex]

Let's turn these values into Improper Fractions.

[tex]\frac{1}{3} - \frac{3}{3} - \frac{3}{3} = -\frac{7}{3}[/tex]

[tex]5=\frac{5}{1}[/tex]

Make the Denominators Equal:

[tex]\frac{5}{1} \times \frac{3}{3} = \frac{15}{3} \ (5)[/tex]

Now, we can simply add.

[tex]-\frac{7}{3} + \frac{15}{3} = \frac{8}{3}[/tex]

Reverse, turn [tex]\frac{8}{3}[/tex] into a mixed fraction.

[tex]\frac{8}{3} - \frac{3}{3} \ (1) - \frac{3}{3} \ (2) = 2\frac{2}{3}[/tex]

Our final answer is [tex]2\frac{2}{3} .[/tex]

The long division process is explained below.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

While doing long division method, you have to follow certain steps.

Consider an example 259 ÷ 9.

259 is the dividend, 9 is the divisor.

First consider the first digit of the dividend, which is 2. But 2 is not greater than or equal to 9.

So take the next digit also and so consider the first two digits.

The first two digits of the dividend is 25.

25 is not a multiple of 9.

The number which is a multiple of 9 nearer to but less than 25 is 18.

18 = 2 × 9.

Write 2 in the quotient and subtract 25 - 18 = 7

Now 7 is less than 9. So bring down the next (third) digit of the dividend, which is 9.

So the number we get is 79.

Again 79 is not a multiple of 9. The nearest lesser multiple of 9 is 72.

72 = 9 × 8

So write 8 in the quotient.

Remainder is 79 - 72 = 7

So we get the quotient as 28 and the remainder is 7.

Hence the simplification of the long division is explained.

This expression will generate all angles coterminal with 240 degrees.

To convert an angle from degrees to degrees, minutes, and seconds, we need to use the following formulas:
1 degree = 60 minutes
1 minute = 60 seconds

First, we need to convert the decimal part of the angle to minutes:
0.32 degrees * 60 minutes/degree = 19.2 minutes

Next, we need to convert the decimal part of the minutes to seconds:
0.2 minutes * 60 seconds/minute = 12 seconds

So, the angle 124.32 degrees is equal to 124 degrees, 19 minutes, and 12 seconds:
124.32 ∘ = 124 ∘ 19 ′ 12 ′′

To convert an angle from degrees, minutes, and seconds to decimal degrees, we need to use the following formulas:
1 degree = 60 minutes
1 minute = 60 seconds

First, we need to convert the minutes to degrees:
36 minutes / 60 minutes/degree = 0.6 degrees

Next, we need to convert the seconds to degrees:
36 seconds / 3600 seconds/degree = 0.01 degrees

So, the angle 48 degrees, 36 minutes, and 36 seconds is equal to 48.61 degrees:
48 ∘ 36 ′ 36 ′′ = 48.61 ∘

To find the angle of least positive measure that is coterminal with a given angle, we need to use the formula:
A = A + 360n

Where A is the given angle, and n is an integer. We need to find the smallest positive value of n that makes the expression equal to a positive angle less than 360 degrees.

For the given angle A = 725 degrees, we can use n = -2:
A = 725 + 360(-2) = 725 - 720 = 5 degrees

So, the angle of least positive measure that is coterminal with 725 degrees is 5 degrees.

To find an expression that generates all angles coterminal with a given angle, we can use the formula:
A = A + 360n

Where A is the given angle, and n is an integer. For the given angle A = 240 degrees, the expression is:
240 ∘ + 360n

This expression will generate all angles coterminal with 240 degrees.

The length of the top of the workbench is 13m and the width is 7m.

To find the length and the width, we can use the formula for the area of a rectangle, which is A = L x W, where A is the area, L is the length, and W is the width. We can plug in the given values and solve for the unknowns.

Let's start by assigning variables to the length and the width. Let's call the width x and the length x + 6 (since the length is 6m greater than the width).

Now we can plug these values into the formula:

A = L x W

91 = (x + 6) x x

91 = x2 + 6x

Now we can rearrange the equation to solve for x:

x2 + 6x - 91 = 0

We can use the quadratic formula to solve for x:

x = (-6 ± √(62 - 4(1)(-91))) / (2(1))

x = (-6 ± √(36 + 364)) / 2

x = (-6 ± √400) / 2

x = (-6 ± 20) / 2

The two possible solutions are:

x = (-6 + 20) / 2 = 7

x = (-6 - 20) / 2 = -13

Since the width cannot be negative, the only valid solution is x = 7. This means that the width is 7m and the length is x + 6 = 7 + 6 = 13m.

So the length of the top of the workbench is 13m and the width is 7m.

Therefore, the retirement account must contain $2,758,686.58 when you retire in order to withdraw $4000 at the end of each quarter for 30 years.

To find the amount that the retirement account must contain when you retire, we can use the formula for the future value of an annuity due:

FV = PMT * [(1 + r/n)^(n*t) - 1] / (r/n) * (1 + r/n)

Where FV is the future value, PMT is the payment amount, r is the interest rate, n is the number of compounding periods per year, and t is the number of years.

In this case, PMT = $4000, r = 0.07, n = 4 (since the account is compounded quarterly), and t = 30.

Plugging these values into the formula, we get:

FV = 4000 * [(1 + 0.07/4)^(4*30) - 1] / (0.07/4) * (1 + 0.07/4)

FV = 4000 * [(1.0175)^120 - 1] / (0.0175) * (1.0175)

FV = 4000 * 11.9478 / 0.0175 * 1.0175

FV = $2,758,686.58

Therefore, the retirement account must contain $2,758,686.58 when you retire in order to withdraw $4000 at the end of each quarter for 30 years.

Iliana needs to play for 16 hours to get a total of 200 XP.

What is  slope-intercept form ?

The slope-intercept form is a way to write the equation of a line in two variables, usually x and y. It is called "slope-intercept" form because it gives the slope of the line and the y-intercept of the line.

The slope-intercept form is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

We can use the points on the graph to find the equation of the line that relates playing time (x) to total XP (y). To do this, we can use the slope-intercept form of a line:

y = mx + b

where m is the slope of the line and b is the y-intercept.

To find the slope, we can use any two points on the line. Let's use points A and B:

m = (y2 - y1) / (x2 - x1) = (50 - 25) / (4 - 2) = 25/2

Now we can write the equation of the line in slope-intercept form:

y = (25/2)x + b

To find the value of b, we can substitute one of the points on the line into the equation. Let's use point A:

25 = (25/2)(2) + b

b = 0

So the equation of the line is:

y = (25/2)x

Now we can use this equation to find how many hours Iliana needs to play to get 200 total XP. We can set y = 200 and solve for x:

200 = (25/2)x

x = (2/25) * 200

x = 16

To solve this problem, we first need to find a common denominator for the fractions in the parentheses.

The common denominator for 12 and 8 is 24, so we can rewrite the fractions as (14/24) and (9/24). Then, we can add these fractions together to get (14/24) + (9/24) = (23/24). Next, we can subtract this fraction from (3/8) by finding a common denominator for 8 and 24, which is 24. We can rewrite (3/8) as (9/24) and then subtract (23/24) from it to get (9/24) - (23/24) = (-14/24). Finally, we can simplify this fraction to get (-7/12).

So, the final answer is:
(3/8) - ((7/12) + (3/8)) = (3/8) - ((14/24) + (9/24)) = (9/24) - (23/24) = (-14/24) = (-7/12)

sqrt(((1.11 - 1.304)²  + (1.13 - 1.304)² + (1.40 - 1.304)² + (1.32 - 1.304)² + (1.14 - 1.304)² + (1.28 - 1.304)² + (1.13 - 1.304)² + (1.8 - 1.304)² + (1.10 - 1.304)² + (1.20 - 1.304)^2) / 9) = 0.247

One common rule of thumb for identifying outliers is to consider any data point that falls more than 2 or 3 standard deviations from the mean to be an outlier. Using this rule, we can identify any values that fall outside the range:

1.304 - 2 * 0.247 = 0.81

1.304 + 2 * 0.247 = 1.798

1.304 - 3 * 0.247 = 0.563

1.304 + 3 * 0.247 = 2.045

Based on this rule, we can see that the data point 1.8 falls outside the range of 1.798, so it can be considered an outlier.
