Step-by-step explanation:

484+479.25=963.25

The general solution of the logistic equation is y = 14 / [1 - C · tⁿ], where a = - 14² / 3 and C is an integration constant. The particular solution for y(0) = 10 is y = 14 / [1 - (4 / 10) · tⁿ], where n = - 14² / 3.

Herein we have a kind of ordinary differential equation with separable variables, that is, that variables t and y can be separated at each side of the expression prior solving the expression:

dy / dt = 3 · y · (1 - y / 14)

dy / [3 · y · (1 - y / 14)] = dt

dy / [- (3  / 14) · y · (y - 14)] = dt

By partial fractions we find the following expression:

- (1 / 14) ∫ dy / y + (1 / 14) ∫ dy / (y - 14) = - (14 / 3) ∫ dt

- (1 / 14) · ln |y| + (1 / 14) · ln |y - 14| = - (14 / 3) · ln |t| + C, where C is the integration constant.

y = 14 / [1 - C · tⁿ], where n = - 14² / 3.

If y(0) = 10, then the particular solution is:

y = 14 / [1 - (4 / 10) · tⁿ], where n = - 14² / 3.

Answer:

$8

Step-by-step explanation:

Answer:

c = 45 and e = 30

Step-by-step explanation:

Since we know that A = 45, B = 90, we can calculate C knowing that the total angle of a triangle is 180, so you do 180-45-90 = 45

Finding the angle C helps us find F by subtracting 45 from 180, since a straight line is 180 degrees, which is 135.

We know that E = 15, and what was said earlier about how the toal angle is 180 in a triangle, we can subtract 15 and 135 from 180, which is 30.

The algorithm justifies the answer of 3/5 as the fraction each person gets.

Representation of the fractions on the second row:

From what you described, two of the loaves were divided into thirds.

This means each person receives one third, and there is one third remaining. Then, this remaining third from the second loaf was further divided into fifths.

Therefore, each person receives one fifth from this remaining third.

So, the representation of the fractions on the second row would be:

Each person receives 1/3 (one third) from the two loaves.

Each person receives 1/5 (one fifth) from the remaining third.

Algorithm/Abstract strategy to justify the 3/5 found as the answer:

To find the final answer of 3/5, we can follow the steps you provided:

Divide two loaves into thirds, giving each person 1/3.

Divide the remaining third from the second loaf into fifths, giving each person 1/5.

Combining the fractions, each person has 1/3 + 1/5.

To add these fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 3 and 5 is 15. We can convert 1/3 and 1/5 to have a denominator of 15:

1/3 = 5/15 (multiplying numerator and denominator by 5)

1/5 = 3/15 (multiplying numerator and denominator by 3)

Now, we can add the fractions:

5/15 + 3/15 = 8/15

Therefore, each person receives 8/15 of a loaf.

Simplifying this fraction, we get 3/5.

Hence, the algorithm justifies the answer of 3/5 as the fraction each person gets.

You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.

When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.

A cuboid has six faces, but each face has a pair that is identical in size and shape.

Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.

To find the surface area of a cuboid, you can add up the areas of all its faces.

However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:

(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.

By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.

Essentially, you are considering one face from each pair and then summing their areas.

Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.

When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.

Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.

Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.

Answer:

The 90% confidence interval is  \(0.445< p < 0.456\)

Step-by-step explanation:

From the  question we are told that

  The sample  size is  \(n = 17592\)

  The number of  binge  drinkers is  \(k = 7851\)

Given that the  confidence level is  90%  then the level of significance is mathematically represented as

          \(\alpha = (100 - 90)\%\)

          \(\alpha = 0.10\)

The critical value  of  \(\frac{\alpha }{2}\)  from the normal distribution table  is  \(Z_{\frac{\alpha }{2} } = 1.645\)

The  sample  proportion is mathematically represented as

      \(\r p = \frac{ 7851}{ 17592}\)

      \(\r p = 0.45\)

Generally the margin of error is mathematically represented as  

      \(E = Z_{ \frac{x}{y} } * \sqrt{\frac{\r p(1 - \r p )}{n} }\)

       \(E =1.645 * \sqrt{\frac{ 0.45 (1 - 0.45 )}{17592} }\)

      \(E =0.00617\)

The  90%  confidence interval is mathematically represented as  

      \(\r p -E < p < \r p +E\)

      \(0.45 -0.00617 < p < 0.45 + 0.00617\)

The degree measure of angle BCD is 130.

What is the measure of angle?

An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, we have

Given:  the diameter EB is parallel to DC, and AB is parallel to ED. The angles AEB and ABE are in the ratio 4: 5.

We can let  ∠AEB be 4x and  ∠ABE be 5x because they are in the ratio 4: 5.

When an inscribed angle contains the diameter, the inscribed angle is a right angle. Therefore by the triangle sum theorem,

= 4x+5x+90 = 180

x = 10 and

∠ABE = 50.

∠ABE =∠BED because they are alternate interior angles and AB||ED.

Opposite angles in a cyclic quadrilateral are supplementary,

so ∠BED + ∠BCD = 180

Use substitution to get ∠ABE + ∠BCD = 180

50 + ∠BCD = 180

∠BCD = 130

Hence, the degree measure of angle BCD is 130.

The construction worker will be able to repaint 6 walls with 4 ½ gallons of paint. Option C

To determine how many walls the construction worker will be able to repaint with 4 ½ gallons of paint, we need to divide the total amount of paint by the amount required per wall.

The worker has 4 ½ gallons of paint, which can be written as 4 + 1/2 gallons.

Each wall requires 3/4 gallon of paint.

To find the number of walls that can be repainted, we divide the total amount of paint by the amount required per wall:

Number of walls = (Total amount of paint) / (Amount required per wall)

Plugging in the values, we have:

Number of walls = (4 + 1/2) gallons / (3/4 gallon)

To simplify the division, we can convert the mixed number 4 1/2 to an improper fraction:

Number of walls = (9/2) gallons / (3/4 gallon)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

Number of walls = (9/2) gallons * (4/3 gallon)

Simplifying the multiplication:

Number of walls = (9 * 4) / (2 * 3) = 36/6 = 6

The rectangle has a length of 8 units along the top and bottom sides, and a height of 6 units along the vertical sides.

A rectangle is a four-sided flat shape with four right angles (90 degree angles) between the sides. It is a type of quadrilateral, which means a shape with four sides.

To find the length of the sides of the rectangle, we can use the distance formula:

d = √((x2 - x1)²+ (y2 - y1)²)

Using the coordinates (-4,4) and (4,4) for the two endpoints of the top side of the rectangle, we get:

d = √((4 - (-4))² + (4 - 4)²) = 8

Since the top side has length 8 and there are two top and two bottom sides of equal length, the perimeter is:

20 = 28 + 2L

where L is the length of one of the vertical sides. Solving for L, we get:

L = (20 - 2*8)/2 = 2

Therefore, the length of the vertical sides of the rectangle is 2 units.

The length of rectangle is 8 units on the x-axis, and the width of rectangle is 4 units along the y-axis.

The whole distance encircling a rectangle's edge is known as its perimeter. It is the total of the measurements of the rectangle's four sides.

The formula for calculating the perimeter P of a rectangle with length L and width W is as follows:

P = 2L + 2W

According to question:

To find the length of the sides of the rectangle, we can use the distance formula:

\(d = \sqrt{((x_{2} - x_{1} )^2+ (y_{2} - y_{1})^2)}\)

Using the coordinates (-4, 4) and (4, 4)

\(d = \sqrt{((4 - (-4) )^2+ (4 - 4)^2)}\) = 8 units

L (length) = 8 Units

So, the length of the horizontal sides (x-axis) of the rectangle is 8 units.

then, the top side has length 8 and there are top and bottom sides are equal length, the perimeter is: P = (8+8) + 2W

20 = 16 + 2W

where, L is the length of one of the vertical sides. Solving for L, we get:

W = (20 - 16)/2 = 2

So, the length of the vertical sides (y-axis) of the rectangle is 2 units.

According to the concept of compound interest, the effective annual yield on your investment of $1800 at a 6.3% interest rate compounded daily is 6.49%.

To find the effective annual yield, we need to use the formula for compound interest:

A = P(1 + r/n)ⁿˣ

Where A is the amount of money at the end of the investment period, P is the principal amount invested, r is the annual interest rate, n is the number of times the interest is compounded in a year, and t is the number of years.

In this case, we know that the principal amount P is $1800, the annual interest rate r is 6.3%, and the interest is compounded daily, which means that n is 365 (the number of days in a year). We need to find the effective annual yield, which is the total amount of interest earned in one year.

To calculate the effective annual yield, we can use the following formula:

Effective Annual Yield = (1 + r/n)ⁿ - 1

Plugging in the values, we get:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

\(L(x) = 40 + 5x\)

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

\(F(x) = 70 + 2x\)

After how many miles the charges for the two companied will be the same?

This is x for which:

\(L(x) = F(x)\)

So
