The velocity on reaching the ground is  288 m/s.

What is the equations of motion?

We know that we can be able to handle the problems that we have here by the use of the equations of motion and that is what we shall do in the problems that follow.

h = ut - 1/2gt^2

h = height

u = initial velocity

g = acceleration due to gravity

t = time

Thus;

h = (18 * 5) - 1/2 * (-32) * 5^2

h =90 + 400

h = 490 feet

Thus the height after five seconds is 490 feet + 800 feet = 1290 feet

Using h = ut + 1/2gt^2

h = 1290 feet

u = 0 m/s when dropped

1290=  + 1/2 * (32) *t^2

1290 = 16t^2

Thus

t = 9s

The velocity when it hits the ground is;

v = u + gt

u = 0 m/s when dropped

v = 32 * 9

v = 288 m/s

Step-by-step explanation:

Assume the average nightly payroll for a city’s downtown restaurants on the weekend is $2200 with a standard deviation of $300. The distribution has a bell-shaped curve. A manager wants to be 99% sure he has this cost covered for the next four weeks and puts away $10,000. Will he have enough? Use your z-score formula result to justify your answer. Please respond with the dollar amount and round to the nearest dollar.

Hint: Round your z-value to the hundredths place and direction of the graph will matter.

Answers

Given statement solution is :- The manager will have enough funds, and the amount set aside ($10,000) is sufficient to cover the payroll for the next four weeks.

To determine if the manager will have enough funds to cover the nightly payroll for the next four weeks, we need to calculate the total cost for four weeks and compare it to the amount set aside.

The nightly payroll has a mean of $2200 and a standard deviation of $300. Since there are seven nights in a week, the weekly payroll can be calculated as:

Weekly Payroll = Nightly Payroll * Number of Nights in a Week

= $2200 * 7

= $15,400

To calculate the total cost for four weeks, we multiply the weekly payroll by four:

Total Cost for Four Weeks = Weekly Payroll * Number of Weeks

= $15,400 * 4

= $61,600

Now, let's calculate the z-score using the formula:

z = (X - μ) / σ

Where:

X = Total Cost for Four Weeks

μ = Mean of the distribution

σ = Standard deviation of the distribution

z = ($61,600 - $2200) / $300

z = $59,400 / $300

z ≈ 198

To determine if the manager will have enough funds to cover the payroll, we need to find the proportion of the distribution that is less than or equal to the z-score. This can be done by consulting a standard normal distribution table or using statistical software.

For a z-score of 198, the proportion in the tail of the distribution is essentially 1 (or 100%). This means that the manager is virtually guaranteed to have enough funds to cover the payroll for the next four weeks.

Since the manager has set aside $10,000, which is less than the calculated total cost of $61,600, he will indeed have enough funds to cover the payroll.

Therefore, the manager will have enough funds, and the amount set aside ($10,000) is sufficient to cover the payroll for the next four weeks.

A computer processes jobs on a first-come, first served basis in a time-sharing environment. The jobs have Poisson arrival rates average 0.6 jobs per minute. The objective in processing these jobs is that they spend no more than 5 minutes, on average, in the system. Assuming exponential service times, how fast does the computer have to process jobs (in minutes), on average, to meet this objective

Answers

Answer:

0.8 minutes

Step-by-step explanation:

From the given information:

The arrival time for the jobs to the computer obeys a Poisson distribution;

Thus, the arrival rate is:

\(\lambda = 0.6 \ jobs \ per \ minute\)

Assuming the average time spent on the jobs in the system is denoted by:

\(W_s= 5 \ minutes\)

The average time a job process in the system can be expressed as follows:

\(W_s = \dfrac{1}{\mu - \lambda}\)

From above formula:

\(\mu =\) service rate

\(\lambda =\) arrival rate

replacing the values;

\(5 = \dfrac{1}{\mu - 0.6}\)

\(5(\mu - 0.6) = 1\)

Open brackets

\(5 \mu - 3 = 1\)

\(5 \mu = 3+ 1 \\ \\ \mu = \dfrac{4}{5}\)

\(\mu =\) 0.8 minutes

A certain television is advertised as a 85-inch TV (the diagonal length). If the width of the TV is 67 inches, how tall is the TV? Round to the nearest tenth of an inch.

Answers

The height of the TV is approximately 52.3 inches when rounded to the nearest tenth of an inch.Hence, the TV is approximately 52.3 inches tall.

To find the height of the TV, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the diagonal) of a right triangle is equal to the sum of the squares of the other two sides.

In this case, the width and height of the TV form the legs of a right triangle, with the diagonal as the hypotenuse.

Let's denote the height of the TV as h. According to the Pythagorean theorem:

h² + 67² = 85²

Simplifying the equation, we have:

h² + 4489 = 7225

Subtracting 4489 from both sides, we get:

h² = 2736

Taking the square root of both sides, we find:

h ≈ 52.3.

Answers

It will take the money 14 years to grow into $34,458.67

How to determine how long will it take for the money to grow into $34,458.67?

Given: principal (P) = $15,000.00, rate (r) = 6% = 0.06, Amount (A) = $34,458.67, compounded every 4 months.

We want to find the time it will take for the money to grow into $34,458.67

The formula for compound interest is:

A = P (1 + r/n)^nt

where n = 12/4 = 3

34,458.67 = 15,000 (1 + 0.06/3)^(3t)

34,458.67/ 15,000 =  (1.02)^(3t)

log (34,458.67/ 15,000) = 3t log(1.02)

3t = log (34,458.67/ 15,000) / log(1.02)

3t = 42

t = 42/3

t = 14 years

Thus, it will take 14 years to grow

Find the area of a circle and use 3.14 for pi

Find the area of a circle and use 3.14 for pi

Answers

The area of the shaded region of a circle with a 100 degree angle and a radius of 3cm, using pi=3.14, is approximately 25.64 square centimeters.

To find the area of the shaded region of a circle, we need to subtract the area of the sector formed by the shaded region from the area of the whole circle.

The area of the whole circle is given by

A = πr²

where A is the area of the circle, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14 (as given in the question).

Substituting the given values, we get

A = π(3cm)²

A = 28.26 cm² (rounded to two decimal places)

Now, let's find the area of the sector formed by the shaded region.

The angle of the sector is given as 100 degrees. To find the area of the sector, we need to use the formula:

A = (θ/360)πr²

where θ is the angle in degrees, r is the radius of the circle, and π is again approximately equal to 3.14.

Substituting the given values, we get

A = (100/360)π(3cm)²

A = 2.62 cm² (rounded to two decimal places)

Finally, we can find the area of the shaded region by subtracting the area of the sector from the area of the whole circle

Shaded area = Area of circle - Area of sector

Shaded area = 28.26 cm² - 2.62 cm²

Shaded area = 25.64 cm² (rounded to two decimal places)

Therefore, the area of the shaded region of the circle is approximately 25.64 square centimeters.

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 4.

Find the critical value that corresponds to a confidence level of 99.9%. Round to three decimal places.

Answers

The critical value is 9.925, rounded to three decimal places.

How to solve

To calculate the critical value for a 99.9% confidence level with a sample size of 4, we will use the t-distribution, since the population standard deviation is unknown.

The t-distribution is used when the sample size is small (usually n < 30) and the population standard deviation is unknown.

First, find the degrees of freedom (df) for the t-distribution, which is equal to the sample size (n) minus 1:

df = n - 1df = 4 - 1df = 3

Next, we need to find the critical value (t) that corresponds to a 99.9% confidence level (or a 0.999 probability) and 3 degrees of freedom. We will look this up in a t-distribution table or use a t-distribution calculator.

Using a t-distribution calculator or table, the t-score corresponding to a 99.9% confidence level (two-tailed) and 3 degrees of freedom is approximately 9.925.

So, the critical value is 9.925, rounded to three decimal places.

We want to calculate the following probability:

\(P(X>44)\)

then, using the information that we are given, we havE:

\(P(X>44)=P(X-\mu>44-40)=P(\frac{X-\mu}{\sigma}>\frac{44-40}{4})=P(\frac{X-\mu}{\sigma}>1)\)

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans

Answers

Let x be the number of hours Pablo was driving.

We know that he used 5/6 gallons of gas per hour of driving.

So, the total amount of gas he used is 5/6 * x.

We also know that he used a total of 5 3/4 gallons of gas.

So, we can set up the equation:

5/6 * x = 5 3/4

To solve for x, we can first convert 5 3/4 to an improper fraction:

5 3/4 = 23/4

Then, we can multiply both sides of the equation by the reciprocal of 5/6:

x = (5 3/4) / (5/6)

x = (23/4) / (5/6)

x = (23/4) * (6/5)

x = 27.6/4

x = 6.9

Therefore, Pablo was driving for a total of 6.9 hours.

Answer:

16.11 (appx.)

Step-by-step explanation:

since l and m are parallel and a line intersects them, so we can say that the line is the transversal. from the figure we see that

7x + 12 = 12x - 28 [they are internal alternate angles and alternate angles are always equal to one another]

now, we can find the value of x from the equation

12x - 7x = 28 + 12

⇒ 5x = 40

⇒ x = 8

so the angle (7x+12)° is ((7*8)+12) = 68°

so (12x-28)° is also equal to 68° [cause of being alternate angles]

now, look at the figure,

angle (9y-77)° & (12x-28)° add upto a straight line as in 180°

and we know (12x-28)° = 68°

so now,

9y-77 = 68

⇒9y = 68+77

⇒9y = 145

⇒y = 16.11 (appx.)
