a local bank branch employs three tellers who can each help a customer on average in 6 minutes, with a standard deviation of 3 minutes. on average, 24 customers arrive at this bank per hour (in a random fashion). how long would customers have to wait if we do pool the employees? that is, we make one line to lead to all three servers. group of answer choices
Answers
Customers have to wait for d) approximately 12 minutes if we do pool the employees.
This can be found by calculating the average waiting time per customer, which is the average service time divided by the average number of customers.
In this case, the average service time is 6 minutes (with a standard deviation of 3 minutes) and the average number of customers is 24. So, the average waiting time per customer is 6/24 = 0.25 hours = 15 minutes.
To ensure that customers do not have to wait any longer than necessary, it is best to have three separate lines for the three tellers. This way, customers are served in the order they arrive, rather than having to wait for one teller to serve all the customers.

The required probability is 0.9544
A z-score is a quantitative measure obtained when a data point from a normal population with mean μ and standard deviation
σ is transformed. It describes the position of the data point representing its distance from the average value of the normal population measured in number of standard deviations. It is given by:
z =(X − μ)/σ
A standard normal table (z-score table) provides the probability to the left of the z-score so obtained.
Number of randomly selected steady smokers is, n=100.
Sample mean is, M=$20.
The population standard deviation is, σ = $5.
To compute the probability that a sample of 100 steady smokers spend between 19 and 21.
Using the definition of a z-score, computing the z-score for X =$19,
z =(X − μ)/σ /[tex]\sqrt{n}[/tex]
[tex]z = \frac{19-20}{5}/\sqrt{100}[/tex]
z = -2
Again using the definition of a z-score to compute the z-score for X = $21,
z =(X − μ)/σ /[tex]\sqrt{n}[/tex]
[tex]z = \frac{21-20}{5}/\sqrt{100}[/tex]
z = 2
The probability that a sample of 100 steady smokers spend between 19 and 21 is obtained as:
P(19< X < 21) = P(-2 < X < 2)
= P(z< 2) - P(z < -2)
= P(z < 2) − [1 − P (z < 2)]
= 0.9772 - (1 - 0.9772)
= 0.9772 - 0.0288
= 0.9544

Dottie went to the movies with her friends. She bought a soda for $2.35, a pack of bubble gum for $1.15, and a chocolate bar for $1.65. How much did Dottie spend in total?
Answers
Answer:
Step-by-step explanation:
The candy bar cost, in dollars, is $1.05
Say the price of a piece of bubble gum is x.
This means that we can represent our scenario with the equation (x+1)+x=1.10, with (x+1) representing the price of a candy bar.
We can then solve from there.
We have given that,
(x+1)+x=1.10
Simplify above expression
2x+1=1.10
2x=0.10 - Subtract From Both Sides
x=0.05 - Divide From Both Sides
So now we have the price of the piece of bubble gum, but we want the cost of the candy bar.
What is the cost?
Cost is the value of money that a company had to spend to produce its goods or services.
Fortunately, we know it costs one dollar more than the piece of bubble gum, so just do 0.05 + 1. This means our candy bar costs $1.05.

jim has received scores of 69 and 82 on his first two 100 point tests. what score must he get on his third 100 point test to keep an average of 85 or greater?
Answers
Jim needs a score of 97 on his third test to keep an average of 85 or greater.
Average refers to the sum of a set of numbers divided by the count of numbers in the set. It gives a typical or central value that represents the set of numbers.
Given,
The average of his first two tests is (69 + 82) / 2 = 75.5.
To get an average of 85,
he needs the sum of his three tests to be 3 * 85 = 255.
So, the sum of his first two tests is 255 - x, where x is the score he needs on the third test.
Therefore, x = 255 - (69 + 82) = 255 - 151 = 104.

Answers
The probability that the sum of the two rolls equals 4 is 1/12.
Given in the question that a single die with 6 sides is rolled twice, we have to calculate the probability that the sum of the two rolls equals 4.
the set of possible outcomes when we roll a die are {1,2,3,4,5,6}
So when we roll two dice there are 6 × 6 = 36 possibilities
The number of possible combinations that will result in a sum of 4 is (1, 3), (2, 2), and (3, 1). Since there are 6 possible outcomes for each die, the probability of rolling a specific combination is 1/36. There are 3 combinations that will result in a sum of 4, so the probability of rolling a sum of 4 is 3/36 or 1/12.

Answers
Three consecutives even integers are 42, 44, and 46.
The three consecutives even integers can be represented as x, x+2, and x+4. We can create an equation to solve for x, using the given information.
3(x+4) = 52 + x + (x+2)
3x + 12 = 54 + 2x
x = 42
Therefore, the three consecutives even integers are 42, 44, and 46. To explain this answer, we can use the equation we created. We know that the sum of the smaller two integers is 52 less than three times the largest. We can represent this as 3(x+4) = 52 + x + (x+2). We can then solve for x by subtracting 2x from both sides and adding 12 to both sides, resulting in x = 42. This means that the three consecutives even integers are 42, 44, and 46.

the vertices of triangle wxy are located at w(-14,20). x(10,4) and y (-2,-4). what is the approximate length of the midsegment parallel to xy?
Answers
The approximate length of the midsegment parallel to xy is 6.63
The midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle and has the same length as each of the two sides.
To find the midpoint of a line segment, we average the x-coordinates and the y-coordinates of its endpoints.
Since the question stated that the midsegment is parallel to xy, we need to find midpoint of xw and yw.
First, let's find the midpoint of side xw:
Midpoint of xw : ((-14+10)/2, (20+4)/2) = (-2, 12)
Midpoint of yw : ((-14-2)/2, (20-4)/2) = (-8, 8 )
The length of a line segment between two points (x1, y1) and (x2, y2) in a two-dimensional coordinate system can be calculated using the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Length line of midpoint xw and midpoint yw :
√((-2-(-8))^2 + (12-(8))^2) = √(6^2 + 4^2) = √(36 + 8) = √44
So, the length of the midsegment is parallel to XY, which is approximately equal to √44 = 6.63

Example: 2 + 3x + 4y = 7 is an expression.
We have,
Logan:
Number of lawns each week = L
Number of lawns 8 weeks = 8L
Eve:
Number of lawns each week = )L - 2)
Number of lawns 8 weeks = 8(L- 2)
a)
The expression represents the number of lawns Eve mowed in those 8 weeks.
= 8(L -2)
b)
When L = 3,
8 (L - 2)
= 8 (3 - 2)
= 8 x 1
= 8
c)
Tabular table
Number of weeks Number of lawns
Logan x xL
Eve x x(L - 2)
d)
Logan:
Number of lawns in one week = 5
L = 5
Eve:
Number of lawns in 8 weeks.
= 8 (L - 2)
= 8 (5 - 2)
= 8 x 3
= 24
Thus,
a) 8(L- 2)
b) 8
c) Tabular table is given above.

the distance from the ground of a person riding on a ferris wheel can be modeled by the equation d equals 20 times the sine of the quantity pi over 30 times t end quantity plus 10 comma where d represents the distance, in feet, of the person above the ground after t seconds. how long will it take for the ferris wheel to make one revolution?
Answers
It takes approximately 26.56 seconds for the ferris wheel to make one revolution.
The ferris wheel makes one complete revolution when the distance of the person above the ground returns to the original value after completing a full circle.
This occurs when the sine function returns to its maximum value, which is 1.
Thus, we have the following equation:
20 * sin(π/30 * t) + 10 = 20
Solving for t,
we will get:
sin(π/30 * t) = 0.5
Taking the inverse sine of both sides:
(π/30 * t) = sin^-1(0.5)
Multiplying both sides by 30/π,
we will get the following:
t = (30/π) * sin^-1(0.5)
Now solving the value of t
We will get it as: t ≈ 26.56 seconds.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 74.5 Mbps. The complete list of 50 data speeds has a mean of x= 17.34 Mbps and a standard deviation of s= 20.79 Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]?
Answers
a. The difference between the highest data speed (74.5 Mbps) and the mean of all 50 data speeds (17.34 Mbps) is:
74.5 - 17.34 = 57.16 Mbps
b. To find the number of standard deviations, divide the difference by the standard deviation:
57.16 / 20.79 = 2.75
So, the difference of 57.16 Mbps is 2.75 standard deviations from the mean.
Mbps known as for “Megabits per second.” This is the standard measure of “speed” or “bandwidth” on home internet connections.
It finds how many bits (units of digital information) can be transferred each second. You’ll normally see speeds ranging from 10-1,000 Mbps advertised for home internet plans.

Avery decides to take her puppy for a walk. After 90 feet, they stop to smell some roses. Then, Avery runs into a friend 200 yards up the road. They start talking, and soon it's time for Avery to go home. So, she and her puppy head back to her house. How many feet long was Avery's walk?
Answers
Answer:
Below
Step-by-step explanation:
90 feet + 200 yrads = 90 feet + 200 *3 feet = 690 feet EACH direction for a total of 690 * 2 = 1380 ft
Answer:
1380 ft long
Step-by-step explanation:
1. You would convert 200 yds to feet. (3ft in a yd so 600 ft.)
2. Add 600+90 to figure out how far she walked to her friend.
3. Double it because she walked the same distance to get home.
