Answers
Answer:
60%
Step-by-step explanation:
New amount - Original amount/ original amount * 100

What is the Volume of the Box?The volume of a box or cuboid is given by the formula:
V = L * W * H
Where:
L is length
W is width
H is height
We are given the external dimensions as:
Length = 22 inches
Width = 15 inches
Height = 12 inches
Since the glass is 1/2 inch thick, then the interior dimensions are:
New length = 22 - 1/2 = 21.5 inches
New Width = 15 - 1/2 = 14.5 inches
New height = 12 - 1/2 = 11.5 inches
Thus:

(round your answers to four decimal places where necessary. report time in minutes.)
Answers
The expected number of customers in the system is 0.96.
Given that the arrivals to the drive-up teller window occur at a rate of 0.4 customers per minute, and the service times are exponentially distributed, we can use queuing theory to determine the operating characteristics of the system.
What is the expected number of customers waiting in line?
We can use the queuing formula Lq = (λ^2) / (μ(μ-λ)), where λ is the arrival rate and μ is the service rate. Here, λ = 0.4 and μ is the reciprocal of the average service time, which we need to calculate.
Assuming the bank tellers can serve customers in an average of 2 minutes, then μ = 1/2 = 0.5.
Plugging these values into the formula, we get:
Lq = (0.4^2) / (0.5(0.5-0.4)) = 0.16 customers
Therefore, the expected number of customers waiting in line is 0.16.
What is the expected time a customer spends in the system?
We can use the queuing formula W = (1/μ) + (Lq/λ), where μ is the service rate and λ is the arrival rate, and Lq is the expected number of customers waiting in line.
Using the same values of λ and μ as before, we can calculate Lq as 0.16 customers. Plugging these values into the formula, we get:
W = (1/0.5) + (0.16/0.4) = 2.4 minutes
Therefore, the expected time a customer spends in the system is 2.4 minutes.
What is the expected number of customers in the system (i.e., both waiting and being served)?
We can use the queuing formula L = λW, where λ is the arrival rate and W is the expected time a customer spends in the system.
Plugging in the values of λ and W that we calculated earlier, we get:
L = 0.4 x 2.4 = 0.96 customers
Therefore, the expected number of customers in the system is 0.96.

Arlene buys a phone case and charging cord for 15% off. The original price of the charging cord, x. enter the correct answers in the boxes. remember to multiply by the discounted percentage as a decimal. the discount is applied to the sum of the cord and the phone case.
Answers
Arlene buys a phone case and charging cord for 15% off
Discount on case and cord = 15%
Original cost of case = $18
Total discount amount = $4.20
Let the original cost of charging cord = x
So, Arlene buys a phone case and charging cord for 15% off = 15% of cost of cord and case
15% of cord and case = 15% of (x + 18)
as the discount amonut ins $18
15% of cord and case = 15% of (x + 18)
15% of cord and case = 4.20
15% of (x + 18) = 4.20
\(\begin{gathered} \text{ 15\% of (x +18) = 4.20} \\ \text{ }\frac{15\times(x+18)}{100}=4.20 \\ 15(x+18)=4.20\times100 \\ 15(x+18)=420 \end{gathered}\)So, the expression is : 15(x + 18) = 420
Simplify the expression for x :
15(x + 18) = 420
15x + 270 = 420
15x = 420 - 270
15x = 150
x = 150/15
x = 10
So, the cost of charging cord is $10

Which function can be used to determine the nth term of the sequence?
Answers
Answer:
Option (C)
Step-by-step explanation:
Recursive formula of sequence is,
\(a_1=-7\)
\(a_n=a_{n-1}-5\)
Therefore, sequence will be in the form of,
-7, -12, -17,......
Therefore, common difference of the given arithmetic sequence,
d = \(a_n-a_{n-1}\)
= -5
Explicit formula for an arithmetic sequence is,
f(n) = a + (n - 1)d
where a = first term of the sequence
n = nth term
d = common difference in each successive term
By substituting the values from the sequence,
f(n) = -7 + (n - 1)(-5)
= - 7 - 5(n - 1)
= -7 - 5n + 5
f(n) = -5n - 2
Option (C) will be the correct option.

1. The outcomes in the sample space of choosing a letter from the word THANKS are: T, H, A, N, K, S.
The outcomes in the sample space of choosing a letter from the word STARK are: S, T, A, R, K.
2. To find the number of outcomes in the sample space, we multiply the number of outcomes for each word.
Number of outcomes in the sample space = Number of outcomes for the first word × Number of outcomes for the second word
Number of outcomes in the sample space = 6 (from THANKS) × 5 (from STARK) = 30.
3. The probability of choosing the letters AA would be the number of favorable outcomes (which is 0 in this case) divided by the total number of outcomes in the sample space.
Probability of choosing AA = Number of favorable outcomes / Total number of outcomes
Probability of choosing AA = 0 / 30 = 0.
Therefore, the probability of choosing the letters AA is 0, as there are no occurrences of the letter A in both words together.

If I choose four cards from a standard -card deck, with replacement, what is the probability that I will end up with one card from each suit
Answers
The probability that I will end up with one card from each suit is 3/32 when I choose four cards from a standard-card deck, with replacement. This can be obtained by finding probability of each draw.
What is the required probability?The probability of drawing first card is one, that is the card can be of any suite.The probability of drawing second card is,
⇒ 52 cards - 13 cards (1 suite) = 39 cards (remaining 3 suites)
On the second draw, we have a (39/52) = (3/4) probability of drawing a different suite from the first draw
The probability of drawing third card is,⇒ 52 cards - 26 cards (2 suite) = 26 cards (remaining 2 suites)
On the third draw we have a (26/52) = (1/2) probability of drawing a suite different from the first two draws
The probability of drawing fourth card is,⇒ 52 cards - 39 cards (3 suite) = 13 cards (remaining 1 suites)
On the last draw we have a (13/52) = (1/4) probability of drawing a different suite from the ones we drew on the first three draws
So the probability = (1) (3/4) (1/2) (1/4) = 3/32
Hence the probability that I will end up with one card from each suit is 3/32 when I choose four cards from a standard-card deck, with replacement.

how many pairs of parallel sides does a pentagon have
Answers
A pentagon can have at most two pairs of parallel sides, but in the case of a regular pentagon, there are no pairs of parallel sides.
A pentagon is a polygon with five sides. To determine the number of pairs of parallel sides a pentagon can have, we need to analyze its properties.
By definition, a polygon with five sides can have at most two pairs of parallel sides. This is because parallel sides are found in parallelograms and trapezoids, and a pentagon is neither.
A parallelogram has two pairs of parallel sides, while a trapezoid has one pair. Since a pentagon does not meet the criteria to be either of these shapes, it cannot have more than two pairs of parallel sides.
In a regular pentagon, where all sides and angles are equal, there are no pairs of parallel sides. Each side intersects with the adjacent sides, forming a continuous, non-parallel arrangement.
Therefore, the maximum number of pairs of parallel sides a pentagon can have is two, but in specific cases, such as a regular pentagon, it can have none.
