A retailer is looking to evaluate its customer service. Management has determined that if the retailer wants to stay competitive, then it will have to have at least a 90% satisfaction rate among its customers. Management will take corrective actions if the satisfaction rate falls below 90%. A survey of 1,200 customers showed that 1,068 were satisfied with their customer service.

Answer:

  13

Step-by-step explanation:

You want the sum of f^-1(-7) and f(-7) given the function definition in the table.

The inverse function f^-1(x) consists of ordered pairs that are the reverse of the ordered pairs (x, f(x)). That is ...

  (x, f^-1(x)) ≡ (f(x), x)

Another way to describe f^-1(x) is "the value of z that gives f(z) = x". This means f^-1(-7) is the value of x that gives f(x) = -7. That x-value is 6:

  f^-1(-7) = 6 . . . . . from the 4th column of the table

We can read the function value directly from the table:

  f(-7) = 7 . . . . . . the first column of the table

Then the sum of interest is ...

  f^(-1)(-7) +f(-7) = (6) +(7)

  f^(-1)(-7) +f(-7) = 13

__

Additional comment

The inverse function ordered pairs are ...

  (x, f^-1(x)) = {(7, -7), (12, 11), (8, -13), (-7, 6), (13, 5)}

Based on given diagram we can conclude that d || e.

As per the diagram given there are some lines and angles which are defined and some of them are to be find so that we can conclude answer from the given options.

The attached image shows the Angles which are solved for the solution of the question as follows;

For line 'a' makes an angle of 110° with line 'd' and as total angle made by a line is always 180° Therefor another angle made by line 'a' with line 'd' will be 180° - 110° = 70° a shown in the attached figure.

For line 'c' makes an angle of 115° with line 'd' and as total angle made by a line is always 180° Therefor another angle made by line 'c' with line 'd' will be 180° - 115° = 65° a shown in the attached figure.

For line 'b' makes an angle of 60° with line 'd' and as total angle made by a line is always 180° Therefor another angle made by line 'b' with line 'd' will be 180° - 60° = 120° a shown in the attached figure.

By Comparing All the angles we can conclude that line a ∦ b, a ∦ c, b ∦ c.

∴ Line 'd' is parallel to line 'e'.  => d || e.

The associative property let us associate different terms or factors in order to solve some expression.

We have to find the expression in which this property is more useful.

The only expression where the associative may be helpful is C, as we can associate this way:

In the other expression there is no advantage in applying this property.

Answer: C

a. The length is (3b) meters

b. length of hall is 36m.

We have given,

a. Breadth of the rectangle = b meters,

Since, length of a rectangular hall is 3 times the breadth of the hall,

⇒ Length = 3 × Breadth

⇒ Length = 3b

Hence, the length of the rectangle is (3 b) meters.

b. if the breadth is 12 m

Then, the length of the hall = [tex]3\times 12[/tex]

                                           = 36m.

Length is a measure of distance. In the International System of Quantities, length is a quantity that has a measured distance. In most  measurement systems, a base unit of length is chosen from which all other units are derived. In the International System of Units, the basic unit of length is the meter.  Length generally refers to  the widest dimension of a fixed object.

The coordinates of the point that at 7/8 from a to b are (5, -5/8)

On the segment, we have the following endpoints

A = (-2, 2)

B = (6, -1)

Also, we have the line ratio to be

Ratio, m : n = 7/8

Express the ratio as a ratio

So, we have

m : n = 7 : 8 - 7

Evaluate the difference

So, we have

m : n = 7 : 1

The coordinate of the point at the given distance is then calculated as

Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)

So, we have

Point = 1/(7 + 1) * (7 * 6 + 1 * -2, 7 * -1 + 1 * 2)

Evaluate the products

So, we have

Point = 1/8 * (42 -2, -7 + 2)

Evaluate the sum and the difference

So, we have

Point = 1/8 * (40, -5)

Evaluate the products

So, we have

Point = (5, -5/8)

Hence, the coordinates of the point that is 7/8 of the distance from a to b are (5, -5/8)

∠2 and ∠4 are corresponding angle.

∠3 and ∠6 are alternate interior angle.

∠6 and ∠7 are consecutive interior angle.

When a transversal intersects two or more lines, alternate exterior angles are produced. These angles are created on the various transversal sides' outer sides.Any two parallel lines that cross a transversal produce a few pairs of angles with the transversal. In the area inside the parallel lines, interior angles are generated, whilst alternate external angles are created in the area outside the parallel lines.

Corresponding angles are those that are created when two parallel lines are intersected by another line, whether it be a transversal or a matching corner (i.e. the transversal). Angle p and angle w, for instance, are the matching angles in the illustration below.

The pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. All of these angles are equal. There is another way to look at this. The alternative interior angles can establish the parallelism or non-parallelism of the given lines. The supplied lines that are crossed by a transversal are said to be parallel if these angles are equal.

The pair of interior angles that are not contiguous to one another and are on the same side of the transversal are referred to as consecutive interior angles. Things that follow one another are referred described as being "consecutive." On a transversal's internal side, adjacent interior angles are found next to one another.

∠1 and ∠8 are alternate exterior angle.

As per the long division, the value of 19 divided by 6,927 is 0.002742

Long division:

Long division is the mathematical method for dividing large numbers into multiple smaller groups or parts. The number which we divide into small groups is called the dividend, the number by which we divide is called the divisor.

Given,

Here  we have to divide the number 19 by 6927.

When we divide the number, we have to following the following steps,

1) Set up the problem with long division bracket. Put dividend inside bracket and divisor on outside left.

2) 6927 goes into 19000 (2-times). Put a 2 in the next place of quotient and multiply 6927 by 2 to get 13854. Subtract 13854 from 19000 to get remainder (19000-13854=5146).

3) Now, bring down 0 from the dividend, to make 51460

4) 6927 goes into 51460 (7-times). Put a 7 in the next place of quotient and multiply 6927 by 7 to get 48489. Subtract 48489 from 51460 to get remainder (51460-48489=2971).

5) Now, bring down 0 from the dividend, to make 29710

6) 6927 goes into 29710 (4-times). Put a 4 in the next place of quotient and multiply 6927 by 4 to get 27708. Subtract 27708 from 29710 to get remainder (29710-27708=2002).

7) Now, bring down 0 from the dividend, to make 20020

8) 6927 goes into 20020 (2-times). Put a 2 in the next place of quotient and multiply 6927 by 2 to get 13854. Subtract 13854 from 20020 to get remainder (20020-13854=6166).

This process is continued so we have to take only up to these one.

Then this can be displayed in the following figure.

Step-by-step explanation:

The radius of the hole to the nearest hundredth of a foot will be 0.20 feet.

The problem we are dealing with here is related to volume, which is referred to as may be a degree of involved three-dimensional space. It is regularly measured numerically utilizing SI-inferred units (such as the cubic meter and liter) or by different majestic units (such as the quart, gallon, and cubic inch) and the volume formula we are referring to is of the cylinder which is,

Volume = πr²h

Where r is the radius of the cylinder, π is the constant which is equal to  3.14 and h is the height of the cylinder.

From the information given to us, the volume of the hole ( cylindrical in  this case ) is  3500 cubic feet and the height is   4.8 miles

So First we Converting  the 4.8 miles to feet,

Since we know 1 mile = 5280 feet

therefore, 4.8 miles = 4.7 × 5280 = 25344 feet

Now putting the desired in the formula,

=>3500 = 3.14 × r² × 25344

=> 79580.16r² = 3500

=>r² = 3500/79580.16

=>r²= 0.04398

=>r = √0.04398
