The average number of callers in the call centre is 112.5.
Number of callers received by the call centre per minute = 25
Average time each person spends on hold = 1 minute
Average time each caller spends talking = 3.5 minutes
The total amount of time of spending by each caller in the call centre is,
= Time spend on hold + Time spend on talking
= 1 + 3.5
= 4.5 minutes
The total amount of time spent by each caller in the call centre is 4.5 minutes.
The average number of callers in the call centre is,
= Total time spent in the call centre × Number of callers per minute
= 4.5 × 25
= 112.5
Therefore, the average number of callers in the call centre is 112.5.

If you can't help me with that answer then can you help me with this one please?
Answer:
73° & 107°
Step-by-step explanation:
1. Those angles are supplementary, so they add up to 180 degrees.
2. (8x - 20) + (8x + 8) = 180
3. You need to add both 8x's together to make 16x. Do the same with -20 & 8. That makes -18. This is binomial addition.
4. 16x - 18 = 180
5. Add 18 to both sides
6. 16x = 198
7. Divide both sides by 16
8. x = 12.375
9. Plug in your x for both angles.

We can not use first two options, because question mentions that x is not negative. So, starting our hit and trial method from 0.
We will keep the value in expression to find the result -
0²>0 + 1
0 > 1
This contradicts or opposes Kevin's statement, as 0 is not greater than 1.
Trying the second number -

These four lines have been graphed on the same coordinate grid. Which lines are parallel to each other?
A. k & m
B. k & l
C. j & l
D. j & m
Answer:
line J and line L are parallel so C.
The parallel line are j and l.
Hence the correct answer is c.
Given are four lines that have been graphed on the same coordinate grid.
We need to check which of these are parallel to each other.
To determine which lines are parallel to each other, we need to compare their slopes. Parallel lines have the same slope.
The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
Let's identify the slopes of the given lines:
Line j: y = (2/3)x + 1/2
Slope of j: 2/3
Line k: y = (1/2)x + 2/3
Slope of k: 1/2
Line l: y = (2/3)x + 3/2
Slope of l: 2/3
Line m: y = (3/2)x + 1/2
Slope of m: 3/2
Now, let's see which lines have the same slope:
A. k & m - The slopes are different (1/2 and 3/2). These lines are not parallel.
B. k & l - The slopes are different (1/2 and 2/3). These lines are not parallel.
C. j & l - The slopes are the same (2/3). These lines are parallel.
D. j & m - The slopes are different (2/3 and 3/2). These lines are not parallel.
So, the correct answer is:

- 5x² - 2x³ - 4x ➜ - 2x³ - 5x² - 4x
To identify the polynomial, we will look at the number of terms. This polynomial has three terms, so it is a trinomial.

Find the perimeter when 121 triangles are put together in the pattern shown below. Assume that all triangle sides are 1 cm long.
Applying the arithmetic sequence formula, the perimeter of the triangle is: 123 cm.
How to Apply the Arithmetic Sequence?An arithmetic sequence formula is given as, T(n) = a + (n - 1)d, where a is the first term; n is the nth number of terms; d is the common difference.
Applying the arithmetic sequence formula to this problem, we have the following:
n = 121
a = 3
d = 1
Substitute
T(121) = 3 + (121 - 1)1
T(121) = 3 + (120)1
T(121) = 3 + 120
T(121) = 123

For each function, find the inverse and the domain and range of the function and its inverse. Determine whether the inverse is a function. f(x)=√x+2
The inverse function of f(x) = √x + 2 would be f⁻¹(x) = x² - 2.
The domain of the function would be {x ∈ R, x ≥ −2}.
The range would be {y ∈ R, y ≥ 0}.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
Considering f(x) = y, to find the inverse function, the x and y values are switched giving the new equation of
x = √y + 2
Simplifying the above equation, we get
x - 2 = √y
x² - 2 = y
x² - 2 = y is the inverse of the function f(x)=√x+2
The domain of the function would be all x, such that x + 2 ≥ 0, or x ≥ −2.
Hence it is {x∈R, x ≥ −2}
For range, consider y =√x + 2.
Since√x+2 ≥ 0, it is obvious that y ≥ 0.
The range would be {y ∈ R, y ≥ 0}

In the morning, the temperature was 15°F. During the day, the temperature decreased 39°F. Which expression can be used to find the temperature at the end of the day?
Responses
The expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.
Given,
The Morning temperature = 15°F
Change in temperature during day time = fall by 39 degree Fahrenheit
The temperature of the end of the day:
Morning temperature + (change in temperature)
Fall by 39° = decrease in temperature by 39° = - 39°
Therefore,
Substitute the values in the expression:
That is,
15°F + (-39°F)
15°F - 39°F
= - 24°F
Therefore, the expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.

What is P(A and B), the probability that a customer has enough cash and a credit card? 4. What is P(A or B), the probability that a customer has enough cash or a credit card?
P(A) = 4 / 20, this is the probability that a customer has enough cash
P (B) =16 / 20, this is the probability that a customer has a credit card.
P (A and B) = 3 / 20, this is the probability that a customer has enough cash and a credit card.

Of the 20 customers,
4 have enough cash to pay for their meal
16 have a credit card and
3 have enough cash and a credit card.
Event A is the probability that a customer has enough cash
Event B is the probability that a customer has a credit card.
P(A) = 4 / 20 = 1 / 5, this is the probability that a customer has enough cash
P (B) =16 / 20 = 4 / 5, this is the probability that a customer has a credit card.
P (A and B) = 3 / 20, this is the probability that a customer has enough cash and a credit card.
To find the probability that a customer has enough cash or a credit card :
The formula used is P(A or B) = P(A) + P(B) - P(A∪B)
P (A or B) = P(A) + P(B) - P (A and B)
= 4 / 20 + 16 /20 - 3 / 20
