The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

x - y - z = 4

z = x - y - 4                           ....1

In descriptive statistics, the standard deviation measures how widely the data points vary from the mean. It describes how values are distributed throughout the data sample and measures how widely apart data points are from the mean.

Sum of all values divided by the number of values.

The amount of tip is $ 6.40 and the total amount including the tip is given by the equation A = $ 38.40

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount including the tip for family be A

Now , the equation will be

The total amount of the bill without the tip = $ 32.00

The percentage of tip = 20 %

So , the amount of tip is = percentage of tip x total amount of the bill without the tip

Substituting the values in the equation , we get

The amount of tip is = ( 20/100 ) x 32

The amount of tip is = $ 6.40

Now , the total amount including the tip A = total amount of the bill without the tip + amount of tip

Substituting the values in the equation , we get

The total amount including the tip A = $ 32.00 + $ 6.40

The total amount including the tip A = $ 38.40

The probability that one or more of the children is a carrier of the recessive allele is 0.988.

The probability that one or more of the children is a carrier of the recessive allele can be calculated using the binomial theorem. The binomial theorem states that the probability of a success in a given trial is the sum of all probabilities of success minus the probability of none of the successes.

Answer:

You would use one quart of red paint and 2.4 quarts of blue paint.

Step-by-step explanation:

You first want to make 3 2/5 into a decimal. To do that you multiply 3x5 and add 2 which equals 17/5. Then you divide 17 by 5 and you get 3.4. So, now you know that you want your blue paint plus your red paint to equal 3.4 So, add 4/5 and 1/3 which equals 1.13333333333. Multiply 1.13333333333 and 3 which equals 3.4. So use the equation (4/5+1/3)x3 and you'll get 3.4. This shows that everything that you do was right.Then multiply just 1/3 x 3 and you'll get your answer which is 1. Then multiply just 4/5 x 3 and you'll get 2.4.

The monthly payment is $1727.82.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Price of the house = $218,500

Down payment = 3.5%

This means,

= 3.5/100 x 218,500

= 7647.5

Now,

Time of loan = 30 years.

This means,

30 years = 30 x 12 = 360 months.

Now,

Rate = 6.5%

This means,

SI = PRT/100

So,

R = 6.5

SI = (210852.5 x 6.5 x 30)/100

SI = 411162.375

Now,

Total amount to pay in 30 years.

The diameter of the back wheel is 163.68 inches.

Diameter is a straight line passing through the center of a circle, connecting two points on the circumference of a circle. It is the longest possible distance between any two points on the circle and is used to measure the size of a circle. The length of the diameter is twice the radius of the circle. The diameter is also the measure of the distance across a circle, rather than the circumference.

To do this, we first need to calculate the circumference of the front wheel, which is the distance around the edge of the wheel. The circumference of a circle is calculated using the formula C = π x D, where C is the circumference and D is the diameter. Therefore, the circumference of the front wheel is 3.14 x 52 = 163.68 inches.

Next, we need to divide the circumference of the front wheel by the number of spokes on the back wheel. Since there is only one spoke on the back wheel, we can divide the circumference of the front wheel by 1. Therefore, the diameter of the back wheel is 163.68 inches.

Special right triangles are right triangles with specific angle measurements whose side lengths follow a certain pattern.

45-45-90 Triangle

A 45-45-90 special right triangle is a triangle that has two 45-degree angles and one 90-degree angle. Remember that in a right triangle, the two shorter sides are called the legs. Additionally, the longest side that is directly across from the right angle is the hypotenuse. In a special right triangle, the legs are equal. Additionally, the hypotenuse is √2 times the leg length. So, if x is the leg, then the hypotenuse is x * √2.

Solving For x and y

In the problem above, x represents one of the legs and y is the hypotenuse. Since this is a 45-45-90 triangle we know that the legs are equal, and one of the legs is 13 units. So, x must equal 13 as well. Then, we know that y must equal x * √2. So, y equals 13√2. This radical cannot be simplified any further, so the final answers are:

The volume of a swimming pool can be calculated as follows:

Volume = Length * Width * Depth

In this case, the length is 20 m, the width is 6 m, and the depth is 3 m, so the volume is:

Volume = 20 m * 6 m * 3 m = 360 m^3

To convert this volume to cubic feet, we can use the conversion factor:

1 m^3 = 35.3147 ft^3

So, 360 m^3 = 360 * 35.3147 ft^3 = 12611.32 ft^3

Rounding to 3 significant figures, the volume of the swimming pool in cubic feet is:

12611.32 ft^3 ≈ 12611 ft^3

Therefore, the volume of the swimming pool in cubic feet to 3 significant figures is 12611 ft^3.

The volume of the swimming pool is 12,800 ft^3.

To find the volume of the swimming pool in cubic feet, we need to convert the measurements to feet and then multiply them together. One meter is equal to approximately 3.281 feet. So, the length in feet is 20 m × 3.281 ft/m = 65.62 ft, the width is 6 m × 3.281 ft/m = 19.68 ft, and the depth is 3 m × 3.281 ft/m = 9.84 ft.

Now, multiply the length, width, and depth together: 65.62 ft × 19.68 ft × 9.84 ft = 12,848.156 ft3.

Rounding to 3 significant figures, the volume of the swimming pool is approximately 12,800 ft3.
