(Do not round until the final answer. Then round to the nearest cent as needed)

Answers

Answer:

$ 28,665.11 must be deposited today into the account.

Step-by-step explanation:

Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:

X x (1 + 4/12) ^ 5x12 = 35,000

X x (1 + 0.333) ^ 60 = 35,000

X x (1,333) ^ 60 = 35,000

X x 1.220999 = 35,000

X = 35,000 / 1.22099

X = 28,665.11

Thus, $ 28,665.11 must be deposited today into the account.

Answer:

A Kite Ahe guessed

Step-by-step explanation:

For a quadrilateral in which the diagonals cross at right angles, such as a rhombus or kite, the area can be found as half the product of the diagonals.

For the purpose here, we can ignore the factor of 1/2, which is the same for both, and simply consider the products of the diagonals.

Kite A has an area proportional to (30 in)(30 in) = 900 in².

Kite B has an area proportional to (20 in)(40 in) = 800 in².

Kite A has a larger area, so will use more paper.

Only Rudy knows why he chose answer C. Perhaps he guessed, rather than doing any math.

Answer:

A. Kite A

Step-by-step explanation:

To determine which of the two kites will use need more paper to make, find the area of each kite.

Kite A:

Area = (d1*d2)/2

d1 = 30 in.

d2 = 30 in.

Area of kite A = (30*30)/2 = 450 in.²

Kite B:

Area = (d1*d2)/2

d1 = 20 in.

d2 = 40 in.

Area of kite B = (20*40)/2 = 400 in.²

✅Kite A will use more paper to make because it has a greater area of 450 in.² than Kite B (400 in.²).

So, Ruby was wrong. He most likely didn't calculate the area of both kites correctly.

A personal identification number (PIN)
consists of four digits. Consider the
PIN 0005 equal to the number 5, etc. Find
the probability that a PIN number is:
a equal to 0000
b less than 8000 and more than 7900
c divisible by 10
d at least 13.

Answers

Using the probability concept, it is found that there is a:

a) 0.0001 = 0.01% probability that a PIN number is equal to 0000.b) 0.0099 = 0.99% probability that a PIN number is less than 8000 and more than 7900.c) 0.1 = 10% probability that a PIN number is divisible by 10.d) 0.9988 = 99.88% probability that a PIN number is at least 13.

What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.

A personal identification number (PIN) consists of four digits, and considering they can repeat, the total number of PINs is:

[tex]T = 10^4 = 10000[/tex]

Item a:

A PIN equals to 0000 is one outcome, hence:

[tex]p = \frac{1}{10000} = 0.0001[/tex]

0.0001 = 0.01% probability that a PIN number is equal to 0000.

Item b:

In this interval, there are 8000 - 7900 - 1 = 99 possible values, hence:

[tex]p = \frac{99}{10000} = 0.0099[/tex]

0.0099 = 0.99% probability that a PIN number is less than 8000 and more than 7900.

Item c:

One in ten numbers are divisible by 10, hence:

[tex]p = \frac{1}{10} = 0.1[/tex]

0.1 = 10% probability that a PIN number is divisible by 10.

Item d:

12 numbers, from 1 to 12, are less than 13, hence 10000 - 12 = 9988 are at least 13, hence:

[tex]p = \frac{9988}{10000} = 0.9988[/tex]

0.9988 = 99.88% probability that a PIN number is at least 13.

Answer:

Step-by-step explanation:

A new pop-up restaurant serving high-end street tacos just opened and is expected to have high demand based on the chef's prior restaurant experience. The pop-up restaurant has only one window where customers order and receive their food. It takes an average of 5 minutes to serve a customer. There is no seating available so the customer exits the system after receiving their order.
Due to the creative marketing strategy of "hiding" the restaurant location, only 10 customers arrive per hour. There is no specific pattern to the distribution of time between arrivals or service times, but from historical data from prior pop-ups, the coefficient of variation for time between arrivals is 2.58 and service time is 0.75.
1. What type of queuing model is this process?
a. single-channel, multi-phase.
b. multi-channel, multi-phase.

3. For new customers, how long do they have to wait in total before they leave with their food?

d. 95 minutes.
e. 15 minutes.
f. 100 minutes.

h. 10 minutes.
i. 0 minutes.
j. 90 minutes.

Answers

Answer:

1. c

2. f

3. d

Step-by-step explanation:

This type of queuing model is an example of "single-channel, single-phase" process.

However, from the information given:

The inter-arrival rate = 10 customers per hour

Arrival time = 6 minutes

Service time = 5 minutes

∴

utilization = service time/arrival time

= 5/6

Time on queue [tex]T_q = p \times \dfrac{utilization }{1 - utilization} \times \dfrac{Cv_a^2 -Cv_b^2}{2}[/tex]

[tex]T_q = 5 \times \dfrac{5/6 }{1 -5/6} \times \dfrac{(2.58^2 -0.75^2)}{2}[/tex]

[tex]T_q = 25 \times 3.60945[/tex]

[tex]T_q = 90.24 \\ \\ T_q \simeq 90 \ mins[/tex]

Thus, customer waiting in the queue line is;

[tex]= \dfrac{T_q}{q} \\ \\ = \dfrac{90}{6} \\ \\ \mathbf{=15}[/tex]

Thus, new customers will have to wait in a total time of;

= waiting time + service time

= 90 + 5

= 95 minutes.

find the diameter of circle Q if angle PQR measures 31° and the arc length of PR is 9 cm

Answers

Answer:

Step-by-step explanation:

Given:

θ = 31°

Arc length of PR = 9 cm

Required:

Diameter

Solution:

Diameter of the circle = 2*radiius = 2*PQl

Arc length = θ/360 × 2πr

Plug in the values into the equation

9 = 31/360 × 2πr

9 = 0.54r

9/0.54 = r

16.6666667 = r

r = 16.7 cm

Radius = 16.7 cm

Therefore,

Diameter = 2*radius = 2*16.7 = 33.4 cm

She pours in red sand until the volume of the sand is 26 1/4 in.3. Then she pours in blue sand. Now the volume of the sand is 43 3/4 in.3. How much does the level of the sand rise when Neelam adds the blue sand?

Answers

The level of the sand rise when Neelam adds the blue sand is 1 inch if Neelam is pouring sand into a clear box to make sand art.

What is volume?

It is defined as a three-dimensional space enclosed by an object or thing.

It is given that:

Neelam is pouring sand into a clear box to make sand art.

The volume of the sand = 43 3/4 - 26 1/4

After simplification:

The volume of the sand = 17 1/2

The height of the sand = 17 1/2 ÷ (7x 2 1/2)

After solving:

The height of the sand = 1 inch

Thus, the level of the sand rise when Neelam adds the blue sand is 1 inch if Neelam is pouring sand into a clear box to make sand art.

A seafood-sales manager collected data on the maximum daily temperature, T, and the daily revenue from salmon sales, R, using sales receipts for 30 days selected at random. Using the data, the manager conducted a regression analysis and found the least-squares regression line to be Rˆ=126+2.37T. A hypothesis test was conducted to investigate whether there is a linear relationship between maximum daily temperature and the daily revenue from salmon sales. The standard error for the slope of the regression line is SEb1=0.65. Assuming the conditions for inference have been met, which of the following is closest to the value of the test statistic for the hypothesis test?

a. t=0.274

b. t=0.65

c. t=1.54

d. t=3.65

e. t=193.85

Answers

Answer: d

Step-by-step explanation:

t= b1- B0/ SE(b1) = 2.37-0/0.65= 3.646 -> 3.65

The closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.

What is a regression line?

A regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.

We have a least-squares regression line to be:

R^ = 126+2.37T

A hypothesis test was conducted to investigate whether there is a linear relationship between maximum daily temperature and the daily revenue from salmon sales.

Using a T-test to find the significance of the slope coefficient is measured:

[tex]\rm t = \frac{b}{SE}[/tex]

Here SE = 0.65

b = 2.37

Put this value in the above expression, we get:

[tex]\rm t = \frac{2.37}{0.65}[/tex]

t = 3.6461 or

t = 3.65

Thus, the closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.
