The perimeter of the paperboard that remains after the semicircle is removed is 93.12 inches

Information given in the problem includes:

A rectangular paperboard measuring 26in long and 16in wide

information for the semicircle are

Width = 16 inches

Radius = 16 / 2 = 8 inches

Length = 26 inches

Circumference of the semi circle is calculated using the formula

= π * radius

Where the radius is 8 inches and π = 3.14.

Substituting in to the formula and solving for the circumference of the semicircle which same as perimeter of the semicircle gives:

= 8 x 3.14

= 25.12

The perimeter would be

Step-by-step explanation:

a) The distance value is the leverage value from the output which is 0.004

b) The 99% prediction interval is [7.676, 9.146]

a) We are interested in finding and reporting the prediction interval on the output.

Thus, the prediction interval on the output is [7.9188, 8.9025]

Let us consider the estimated value for y as yₓ

We have

x₁ = 3.7, x₂ =3.9, x₃ = 6.5, β₀= 7.5891, β₁ = -2.3577, β₂= 1.6122, β₃= 0.5012

We know that yₓ = β₀ +β₁x₁ + β₂x₂ + β₃x₃

By substituting the value

x₁ = 3.7, x₂ =3.9, x₃ = 6.5, β₀= 7.5891, β₁ = -2.3577, β₂= 1.6122, β₃= 0.5012 into the above equation we get

yₓ =7.5891-(2.3577*3.7)+(1.6122*3,9)+(0.5012*6.5) = 8.411

Let us calculate the value for the prediction interval

The 100 (1 - a) \% prediction interval is

yₓ ±(tₐ/₂ * x * s* √ 1+distance value )

The distance value is the leverage value from the output which is 0.004

We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235. By substituting these values we find that the 95% prediction interval is

8, 411 + (2.3788 * 0.235sqrt(1 + 0.04)) = [7.841, 8, 981]

b) If Enterprise Industry's plan to have in inventory of the number of bottles implied by the upper limit of the prediction interval, which is approximately 9, it can be very confident that it will have enough bottles to meet demand for detergent in the future sales period.

Thus, the bottles are approximately 9

By multiplying the number of bottles implied by the lower limit of the prediction interval, that is approximately 8, by the price of the detergent that is $3.7. we get the minimal revenue from detergent in the future sales period that is $29.6

We are interested in calculating a 99% prediction interval for the demand of detergent in the future sales period

We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235 By substituting these values, we find that the 95% prediction interval is as follows

8, 411 ± (3.067 * 0.235sqrt(1 + 0.04)) = [7.676, 9.146]

Therefore the 99% prediction interval is [7.676, 9.146]

The 50th partial sum of the given arithmetic sequence is 4600

From the question, we are to calculate the 50th partial sum of the given arithmetic sequence

The given arithmetic sequence is

-6, -2, 2, 6, ...

To find the 50th partial sum of the sequence, we will find the sum of the first 50 terms in the sequence.

The sum of n terms of a sequence is given by the formula,

S = n/2(a + l)

Where a is the first term

and l is the last term

l is given by

l = a + (n - 1)d

Where d is the common difference

In the given series

a = -6

d = -6 -(-2) = -6 + 2 = 4

To find the 7th term of (3x - 4/x²)¹⁴, we can use the binomial theorem, which states that for any positive integer n and any real numbers a and b:

(a + b)ⁿ = ∑(C(n, k) x a^(n-k) x b^k)

The wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.

The basic idea behind this method is that if we capture a random sample of animals from a population, tag them, and release them back into the population, then later capture another sample of animals, the ratio of tagged to untagged animals in the second sample can be used to estimate the total population size.

To estimate the total population of wild hogs in the area, we can use the capture-recapture method.

In this case, the wildlife group tagged and released 20 wild hogs, and later counted 8 wild hogs out of the 40 they saw. We can set up a proportion to estimate the total population size:

(Tagged hogs in first sample) / (Total population size) = (Tagged hogs in second sample) / (Number of hogs in second sample)

Putting the values,

⇒ 20 / x = 8 / 40

Simplifying and solving for x, we get:

⇒ x = (20 × 40) / 8 = 100

⇒ x = 100

Therefore, the wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.

Therefore, note that every line segments that appear tangent and intersect each other outside the circle have the same length.

Thus, we have:

To find the ordered pair solutions for the system of equations y = -x² + 2 and y = x, we can set the two equations equal to each other:

-x² + 2 = x

Now we can rearrange this equation into standard quadratic form by moving everything to one side:

-x² + x + 2 = 0

We can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = -1, b = 1, and c = 2

Plugging these values into the formula, we get:

x = (-1 ± √(1 - 4(-1)(2))) / 2(-1)

x = (-1 ± √9) / (-2)

x = (-1 ± 3) / (-2)

So the solutions for x are x = -1 and x = -2.

To find the corresponding values of y, we can plug these values of x into either of the original equations. Let's use y = x:

When x = -1, y = -1

When x = -2, y = -2

Therefore, the ordered pair solutions for this system of equations are (-1, -1) and (-2, -2).

The line segment XY is tangent to circle Z by using the Pythagorean theorem to find the radius of the circle, and the formula for the distance between a point and a line to find the distance between the center of the circle and the line.

Now let's look at the information given in the problem. We are given the length of line segment XY, which is 3.6 units. We are also given the lengths of two line segments that connect the endpoints of XY to the center of the circle Z: YZ, which is 1.8 units, and ZX, which is 2.7 units.

To determine if XY is tangent to circle Z, we need to check if it is possible for a circle with center Z and radius r to pass through points X and Y. If it is not possible, then XY must be tangent to the circle.

In this case, we can use the lengths of YZ and ZX as the legs of the right triangle, and r as the hypotenuse. We can set up the following equation:

r² = YZ² + ZX²

Substituting the given values, we get:

r² = 1.8² + 2.7²

r² = 7.29

r = √7.29

r ≈ 2.7

Now that we know the radius of circle Z, we can check if it is possible for it to pass through points X and Y. To do this, we need to find the distance between the center of the circle and the line XY. If this distance is equal to the radius of the circle, then XY is tangent to the circle.

To find the distance between the center of the circle and the line XY, we can use the formula for the distance between a point and a line. This formula is:

distance = |Ax + By + C| / √(A² + B²)

where A, B, and C are constants that depend on the equation of the line, and x and y are the coordinates of any point on the line.

In this case, we can use the equation of line XY, which is:

y = 0

Substituting this into the formula, we get:

distance = |A(0) + B(1) + C| / √(A² + B²)

distance = |B| / √(B²)

distance = 1 / √1

distance = 1

Since the distance between the center of circle Z and line XY is 1 unit, and the radius of circle Z is also 1 unit, we can conclude that XY is tangent to circle Z.

To find the total cost of interest, we first need to find the total payment over the life of the loan:

Total payment = Monthly payment x Number of payments

Total payment = $370.41 x (30 x 12)

Total payment = $133,347.60

Next, we need to subtract the principal (loan) amount to find the total interest paid:

Total interest = Total payment - Principal

Total interest = $133,347.60 - $69,000

Total interest = $64,347.60

Rounding to the nearest whole dollar, the total cost of interest is $64,348.

lesser x = 9

greater x = 11

Step-by-step explanation:

(x-10)² - 1 = 0

(x-10)² = 1

(x-10) = +- root1 (positive and negative root1)

So (x-10) = +1 and (x-10) = -1

Firstly

X - 10 = 1

X = 11

Secondly

X - 10 = -1

X = 9

So you have x = 9, and x = 11

The smaller one is the lesser x (9)

The larger one is the greater x (11)
