Answer:
They have an 89% satisfaction rate, less than the goal.
Step-by-step explanation:
To find this, divide 1068/1200, this gives you 0.89
This shows that they have an 89% satisfaction rate.
Since, the satisfaction rate 89% which is less than 90%. Therefore, management will take corrective actions.
Given that, if the retailer wants to stay competitive, then it will have to have at least a 90% satisfaction rate among its customers.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
A survey of 1,200 customers showed that 1,068 were satisfied with their customer service.
Here, the satisfaction rate = 1068/1200 ×100
= 0.89 ×100
= 89%
Since, the satisfaction rate 89% which is less than 90%. Therefore, management will take corrective actions.

Long division worked out 19 divided by 6,927
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.

You roll a six-sided die twice. What is the probability of rolling a 2 and then a 6?A.1 / 3B.1/6C.1/36D.1/12
Answer:
C. 1/36
Explanation:
The probability of rolling a 2 in a six-sided die is 1/6 because there are 6 possible outcomes and 1 of them is 2. In the same way, the probability of rolling a 6 is also 1/6 because there are 6 possible outcomes and 1 of them is 6.
Then, the probability of rolling a 2 and then a 6 can be calculated as:
[tex]P=\frac{1}{6}\times\frac{1}{6}=\frac{1}{36}[/tex]Because they are independent events and each one has a probability of 1/6.
Therefore, the answer is:

What is the least common dominator of 5/12, 7/16
Answer:
the least common denometer for 5/12, 7/16 would be 48.
Step-by-step explanation:
On a coordinate plane, point A is located (-2,2) and point B is located at (6,-1). Determine the coordinates of the point that is 7/8 of the distance from a to b
The coordinates of the point that at 7/8 from a to b are (5, -5/8)
How to determine the coordinate of the point on the line segment?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)

∠3 and ∠6 are alternate interior angle.
∠6 and ∠7 are consecutive interior angle.
What is alternate exterior 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.
what is corresponding angle ?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.
What is alternate interior angle ?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.
What is consecutive interior angle ?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.

Currently, the hole is in the shape of a cylinder whose volume is approximately 3500 cubic feet and whose height is 4.8miles. Find the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are used.)
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

Inverse functionThe 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
Function valueWe can read the function value directly from the table:
f(-7) = 7 . . . . . . the first column of the table

How to find the quotient between the two fractions?So let's define two fractions as:
a/b and c/d.
The quotient between the fractions a/b and c/d can be written as:
(a/b)÷(c/d).
Now, the quotient is equal to the product with the inverse, so we can rewrite this as:
(a/b)÷(c/d) = (a/b)*(d/c)
Now, in this case, we want to find 3/4 divided by 2/3, this will be:
(3/4)÷(2/3) = (3/4)*(3/2) = 9/8
