An accident in a laboratory results in a room being contaminated by a radioisotope with a half-life of 8 days. If the radiation is measured to be eight times the maximum permissible level, how much time must elapse before the room is safe to enter?

Answers

Answer:

24 days

Step-by-step explanation:

Let the permissible time be Ro

Let the initial activity be R= 8Ro

From;

0.693/t1/2 × t= 2.303 log R/Ro

Half life of the radionuclide= t1/2 = 8 days.

Hence;

0.693/8 × t = 2.303 log 8

t= 2.1/0.087

t= 24 days

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

x + 5y = 0

3y + 2x = -21

Step 2: Rewrite Systems

x + 5y = 0

Subtract 5y on both sides: x = -5y

Step 3: Redefine Systems

x = -5y

3y + 2x = -21

Step 4: Solve for y

Substitution

Substitute in x: 3y + 2(-5y) = -21Multiply: 3y - 10y = -21Combine like terms: -7y = -21Isolate y: y = 3

Step 5: Solve for x

Define equation: x + 5y = 0Substitute in y: x + 5(3) = 0Multiply: x + 15 = 0Isolate x: x = -15

Answers

Answer:

See Below

Step-by-step explanation:

I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.

We are converting between different units of measurement.

Here are the conversions to know:

12 inches = 1 foot

3 feet = 1 yard

1760 yard = 1 mile

5280 feet = 1 mile

We need to convert 7 feet into inches.

7 feet * 12 inches per foot = 84 inches

Now we know:

84 inches = 7 feet

What's the difference is between 84 inches, and 18 inches?

84 inches - 18 inches = 66 inches

We need 66 more inches to get a length of 7 feet.

We need to convert 2 miles into yards.

2 miles * 1760 yards per mile = 3520 yards.

Now we know:

3520 yards = 2 miles

What's the difference between 3520 yards and 2000 yards?

3520 yards - 2000 yards = 1520 yards

We need 1520 more yards to make 2 miles

We need to convert 108 inches into feet.

108 inches / 12 inches per foot = 9 feet

Since there is no remainder,

9 feet = 108 inches.

Hopefully you can see what is going on here and do the rest yourself.

The American College Testing Corporation has a test called the ACT that is used for admissions to college. The American College Testing Corporation reports that students who attend 2-year colleges in the Midwest United States have an average ACT score of 21.5, with a standard deviation of 3.17. The president of the Minneapolis Community College wonders if students who attend her college have a ACT scores that are significantly different from the ACT scores reported by the American College Teaching Corporation. The president would perform a ___________ test, and use a z-critical value of _____.

Answers

Answer:

Two tailed test

+/-1.96

Step-by-step explanation:

Following this claim, the president would have to perform a two tailed test. Since he wants to know if the Act scores of students in her school are significantly different from what is reported by the ACT corporation.

At a confidence level that is 95%, the level of significance is = 0.05. then the z critical value to be used would be +/- 1.96

Mallie's car dealership expects to sell 18 cars every 6 days. Based on this information, how many days does the dealership expect that it will take to sell 90 cars

Answers

Answer:

30 days

Step-by-step explanation:

1 way:

18 cars/6 days = 3 cars/1 day

90cars/3 cars a day= 30 days

another way:

90 cars/18 cars= 5

6 days * 5= 30 days

A food manufacturer uses an extruder (a machine that produces bite-size cookies and snack food) that yields revenue for the firm at a rate of $200 per hour when in operation. However, the extruder breaks down an average of two times every day it operates. If Y denotes the number of breakdowns per day, and suppose Y follows a Poisson distribution. The daily revenue generated by the machine is R=1600−50Y^2. Find the expected daily revenue for the extruder.

Answers

Answer:

$1300

Step-by-step explanation:

λ = average = 2 per day, Y denotes the number of breakdowns per day,

But E(Y) = λ, E[Y(Y - 1)] = λ²

E(Y²) = E[Y(Y - 1)] + E(Y), hence:

E(Y²) = λ² + λ

The daily revenue is R=1600−50Y². The expected daily revenue for the extruder E(R) is:

E(R) = E(1600−50Y²) = 1600 - 50E(Y²)

E(R) = 1600 - 50(λ² + λ)

Substituting:

E(R) = 1600 - 50(2² + 2)

E(R) = 1600 - 300 = 1300

E(R) = $1300

The car would have traveled 1,018.4 miles in 19 hours because you have to multiply 1 by 19 to get to 19 so you would have to do the same to the miles and 53.6 times 19 is 1,018.4 miles.

g When comparing the 90 percent prediction and confidence intervals for a given regression analysis Multiple Choice the prediction interval is narrower than the confidence interval. the prediction interval is wider than the confidence interval. there is no difference between the size of the prediction and confidence intervals. no generalization is possible about their comparative width.

Answers

Answer:

the prediction interval is wider than the confidence interval

Step-by-step explanation:

Given that the confidence intervals depicts how a researcher got its parameter of interest, for example, regression coefficient, and prediction intervals show the researcher where to find the subsequent sampled data.

Therefore, Prediction intervals must cater to the uncertainty in estimating the population mean, and the random variation of the individual values.

Hence, when comparing the 90 percent prediction and confidence intervals for given regression analysis, a prediction interval is invariably wider than a confidence interval.

This explains the fact that the prediction interval will not collapse to a single value as the sample size rises.
