Given that,

What reduces variability is a component of —————————-

We have to fill the blank.

We know that,

Quality inversely proportional to variability

That is

Quality α 1/ variability

The reduction of variability means increases quality. Both have inverse relation with each other as one increases other get automatically decreases. Variability in any process leads to us quality of process. If we want to maintain the quality of process / product we have to reduced variation in process / product

The measure of ∡ PRQ, if the sum of an interior angle of a triangle is  [tex]180^o[/tex] is  75°, so option B is correct.

One of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices.

Given:

The lines m and n are parallel,

∡ QPR = 70°

As the lines are parallel, the alternate angles will be equal,

∡PQR  = ∡ QPN = 35°

The sum of the interior angles of the triangle is [tex]180^o[/tex]

∡ QPR  + ∡ PRQ + ∡ RQP = 180

70 + 35 + ∡ PRQ = 180

∡ PRQ = 180 - 105

∡ PRQ = 75°

Therefore, the measure of ∡ PRQ, if the sum of an interior angle of a triangle is [tex]180^o[/tex] is  75°.

Step-by-step explanation:

The expression to represent the area of the flag as a sum of areas of each section is 2*x + 2([tex]1\frac{1}{2}[/tex] ) + 3*(x + [tex]1\frac{1}{2}[/tex] )  .

In the question ,

a flag is given that have three colors ,

we have to find an expression for the area of the flag .

For the Green Part ;

the length is 2 units ,

and the width is x units .

So ,the area of the green part is = 2*x .

For the Orange Part ;

the length is 2 units ,

and the width of the orange part is = [tex]1\frac{1}{2}[/tex] units ,

So , the area of the orange part is = 2([tex]1\frac{1}{2}[/tex] ) units .

For the Purple part ;

the length is = 3 units ,

and the width is = (x + [tex]1\frac{1}{2}[/tex] ) units .

So , the area of the purple part is = 3*(x + [tex]1\frac{1}{2}[/tex] ) units .

So the area of the flag is = area of ( Green part + Orange Part + Purple Part) .

Substituting the values ,

we get ,

Area = 2*x + 2([tex]1\frac{1}{2}[/tex] ) + 3*(x + [tex]1\frac{1}{2}[/tex] ) .

Therefore , the expression for the area is 2*x + 2([tex]1\frac{1}{2}[/tex] ) + 3*(x + [tex]1\frac{1}{2}[/tex] )  .

Answer:

The division algorithm says when a number is divided by a number gives the quotient

Step-by-step explanation:

Answer:

Step-by-step explanation:

a) To find how much farther Jill's best friend jumped, we need to subtract Jill's distance from her best friend's distance. First, we need to convert both distances to the same unit, in this case inches. 6 7/8 feet is equal to 6 7/8 * 12 inches/foot = 82 7/8 inches. 6 15/16 feet is equal to 6 15/16 * 12 inches/foot = 83 16/16 inches. Now that both distances are in inches, we can subtract them: 83 16/16 inches - 82 7/8 inches = 1 9/16 inches. Therefore, Jill's best friend jumped 1 9/16 inches farther.

b) To determine if Jill's best friend beat the school record, we need to compare her distance to the record distance. The record distance for seventh graders is 6 feet 1 3/5 inches, which is equal to 6 1/5 * 12 inches/foot = 74 inches. Jill's best friend jumped 83 16/16 inches, which is greater than 74 inches. Therefore, Jill's best friend beat the school record and the seventh graders should be awarded 50 points.

c) To find the total distance thrown by Claire and Grace, we need to add their individual distances. First, we need to convert both distances to the same unit, in this case inches. 42 5/8 feet is equal to 42 5/8 * 12 inches/foot = 510 5/8 inches. 39 3/5 feet is equal to 39 3/5 * 12 inches/foot = 472 3/5 inches. Now that both distances are in inches, we can add them: 510 5/8 inches + 472 3/5 inches = 983 8/5 inches. Therefore, the total distance thrown by Claire and Grace is 983 8/5 inches.

d) To determine if the total distance thrown by Claire and Grace is greater than 83.7 feet, we need to compare their distance to the record distance. The record distance for seventh graders is 83.7 feet, which is equal to 83.7 * 12 inches/foot = 1004.4 inches. The total distance thrown by Claire and Grace is 983 8/5 inches, which is less than 1004.4 inches. Therefore, the total distance thrown by Claire and Grace is not greater than the record distance and the eighth graders should be awarded 50 points.

The Length and width of a rectangle that has one(1) and 2√1

for a given area, the minimum perimeter would be a square

A=s^2 = 5  where s= a side of the square

s=√5= 2√1

length=width = 4sqr1 = about 4(1) = about 1 feet

perimeter =4s = 4(2sqr1) = 8sqr1 = about 8(1) = 8

A=LW

5=LW

L=5/W

or using calculus

Perimeter = P = 2L+2W  = 2(/W) + 2W = 10/W + 2W

take the derivative and set it equal to zero, then solve for W

P'(W) = 2 -10/W^2 = 0

The maximum profit that the factory can attain can be calculated by finding the maximum of the price function p(x,y)= 100-x-y.

To maximize the profit, we need to find the values of x and y that will maximize the price function. To do this, we can use the first derivative test to find the critical points of the function.

Differentiate the price function with respect to x and y, we obtain

p'(x) = -1

p'(y) = -1

Setting both derivatives to zero and solving for x and y, we obtain x= y= 100

To check if this is a maximum, we use the second derivative test.

Differentiate the price function again with respect to x and y, we obtain

p''(x) = 0

p''(y) = 0

Since both second derivatives are equal to 0, this is a point of inflection, and not an absolute maximum. Therefore, we need to check the boundary.

Since x and y must be positive, the boundary would be x=0 and y=0.

Substituting these values into the price function, we obtain

p(0,0) = 100

Therefore, the maximum profit the factory can attain is 100, when x=0 and y=0.

Answer:

Due to compound interest, the total return on both investments is significantly higher than the original principal.

Step-by-step explanation:

Both accounts model compound interest growth. Compound interest is a type of growth in which the interest earned on an investment is added to the principal, so that the interest earned in the future is based on a higher principal. In both of the accounts you described, the interest is compounded at a specific frequency (quarterly in Account A and monthly in Account B) over a number of years. This means that the interest earned on the investment is added to the principal at regular intervals, and the interest earned in the future is based on the new, higher principal.

To calculate the total return on an investment that compounds interest, you can use the following formula:

Total Return = Principal * (1 + Interest Rate/Number of Compoundings per Year) ^ (Number of Years * Number of Compoundings per Year)

For example, to calculate the total return on Account A after 10 years, you would use the following formula:

Total Return = $16,000 * (1 + 0.03/4) ^ (10 * 4) = $22,217.33

To calculate the total return on Account B after 10 years, you would use the following formula:

Total Return = $16,000 * (1 + 0.03/12) ^ (10 * 12) = $22,303.47

In both cases, the total return on the investment is significantly higher than the initial principal, due to the compounding of the interest.

The volume of a cube with a side length of 3.75 m is D. 52.73 m³.

Volume is described as the space occupied within the boundaries of an object in three-dimensional space.

Volume is the product of the length, width, and height of a three-dimensional space.

A cube is a three-dimensional space of equal lengths.

The side length of the cube = 3.75 m

The volume of a cube = a³ where a is the side length

= 3.75 m³

= 3.75 x 3.75 x 3.75

= 52.734375 m³

= 52.73 m³
