The Athens-Clarke Country Wildlife Resource Center wanted to encourage wildlife preservation efforts among students in its summer camp. In the past, it would run a particular curriculum, then gauge students' interest in wildlife preservation in a test at the end of the camp. Historically, the average on this final test to gauge preservation interest was 35.3 (out of 100).

Last summer, the resource Center created a new curriculum focusing on campers interacting directly with wildlife to promote preservation efforts. This included efforts in species dentrication handling of wild animals, and directoration of animals in habitat The Resource Center considers the collection of 40 to be a random samping from the population of campers they will encounter They need your help to determine whether this new curriculum Improves impressions about witte preservation. For their 40 scores at the end of lut summer, they found a sample mean of 26.58 and a standard deviation of 3.18.

Which summation formula is equivalent to the one below?​

Answers

Answer:

The second summation, counting from the top.

Step-by-step explanation:

Remember the relation:

[tex]a^{-n} = \frac{1}{a^n}[/tex]

The first summation is:

4*(  (-1/2)^0 + (-1/2)^1 +  (-1/2)^2 + (-1/2)^3)

4*( 1 - 1/2 + 1/4 - 1/8) = 2.5

Now let's analyze the options.

Let's look at option A, here we only have 2 to different powers, so we never can have a summation equal to 2.5, then we can discard that option.

Let's look at the next one (B), it will be equal to:

= (1/4)*( (-2)^4 + (-2)^3 + (-2)^2 + (-2)^1) =

= (1/4)*( 16 - 8 + 4 - 2) = 2.5

Then this summation is the one equivalent to the first one.

There are 4 points that form a rectangle. Three of the points are: (-5 -1) (-5 3) (2<3 What are the coordinates of the fourth point?

Answers

Answer:

[tex]C = (2,-1)[/tex]

Step-by-step explanation:

Given

[tex]A = (-5,-1)[/tex]

[tex]B = (-5,3)[/tex]

[tex]D = (2,3)[/tex]

Required

The coordinate of the fourth point (C)

The given coordinates indicate the rectangle is vertical/horizontal because it has similar x and y values.

The coordinate of such rectangle can be represented as:

[tex]A = (x_1,y_1)[/tex]

[tex]B = (x_1,y_2)[/tex]

[tex]C = (x_2,y_1)[/tex]

[tex]D = (x_2,y_2)[/tex]

By comparing the general coordinates with the given coordinates, we have:

[tex]x_1 = -5[/tex] --- see A and B

[tex]y_1 = -1[/tex] --- see A and C

[tex]x_2 = 2[/tex] ---- see C and D

[tex]y_2 = 3[/tex] --- see B and D

So, we have:

[tex]C = (x_2,y_1)[/tex]

[tex]C = (2,-1)[/tex]

Answer is:

C. (2, -1)

To graduate this semester, you must pass Statistics 314; and you estimate that you have an 85% chance of passing. You need to pass Math 272 or Math 444, each of which you have an 80% chance of passing: so you will take both in hopes that you will pass at least one. Further, you must pass German 320, which you believe you have a 90% chance of passing. Assuming your chances of passing each class you take are independent, what is your probability of graduating this semester

Answers

Answer:

Probability of graduating this semester is 0.7344

Step-by-step explanation:

Given the data in the question;

let A represent passing STAT-314

B represent passing at least in MATH-272 or MATH-444

M1 represent passing in MATH-272

M2 represent passing in MATH-444

C represent  passing GERMAN-32

now

P( A ) = 0.85, P( C ) = 90, P( M1 ) = P( M2 ) = 0.8

P( B ) = P( pass at least one of either MATH-272 or MATH-444 ) = P( pass in MATH-272 but not MATH-444 ) + ( pass in MATH-444 but not in MATH 272) + P( pass both )

P( B ) =  P( M1 ) × ( 1 - P( M2 ) ) + ( 1 - P( M1 ) ) × P( M2 ) + P( M1 ) × P( M2 )

we substitute

⇒ 0.8×0.2 + 0.2×0.8 + 0.8×0.8 = 0.16 + 0.16 + 0.64 = 0.96

∴ the probability of graduating this semester will be;

⇒ P( A ) × P( B ) × P( C )

we substitute

⇒ 0.85 × 0.96 × 90

0.7344

Probability of graduating this semester is 0.7344

Ryan just got hired for a new job and will make $48,000 in his first year. Ryan was
told that he can expect to get raises of $3,500 every year going forward. How much
money in salary would Ryan make in his 24th year working at this job?

Answers

Answer:

$128,500

Step-by-step explanation:

Find out how much he will earn from his 1st year to 24th.

1st year = 48000

2nd year = 48000 + 3500 = 51500

3rd year = 51500 + 3500 = 55000

4th year = 55000 + 3500 = 58500

5th year = 58500 + 3500 = 62000

6th year = 62000 + 3500 = 65500

7th year = 65500 + 3500 = 69000

8th year = 69000 + 3500 = 72500

9th year = 72500 + 3500 = 76000

10th year = 76000 + 3500 = 79500

11th year = 79500 + 3500 = 83000

12th year = 83000 + 3500 = 86500

13th year = 86500 + 3500 = 90000

14th year = 90000 + 3500 = 93500

15th year = 93500 + 3500 = 97000

16th year = 97000 + 3500 = 100500

17th year = 100500 + 3500 = 104000

18th year = 104000 + 3500 = 107500

19th year = 107500 + 3500 = 111000

20th year = 111000 + 3500 = 114500

21st year = 114500 + 3500 = 118000

22nd year = 118000 + 3500 = 121500

23rd year = 121500 + 3500 = 125000

24th year = 125000 + 3500 = 128500

Step-by-step explanation:

A study9 compared personality characteristics between adult children of alcoholics and a control group matched on age and gender. For the 29 pairs of women, the authors reported a mean of 24.8 on the well-being measure for the children of alcoholics, and a mean of 29.0 for the control group. They reported t = 2.67 for the test comparing the means. Assuming that this is the result of a dependent-samples analysis, identify the df for the t test statistic, report the P-value, and interpret.

Answers

Answer:

df.= 28

P - value = 0.0124 < 0.05

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

Step-by-step explanation:

As the given test is dependent or paired test the degrees of freedom is n-1 = 20-1 = 28

The reported t = 2.67

The P value for ∝= 0.05 at  calculated t= 2.67 and 28 d.f is 0.0124 which is less than 0.05 .

The null hypothesis is rejected.

The null hypothesis is that there is no difference between the means of the two samples.

H0: u1 = u2

The alternate hypotheis is accepted that there is  difference between the means of the two samples.

Ha: u1≠ u2

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

Answers

Answer:

B. g(x) = (1/4x)²

Step-by-step explanation:

g(x) experiences a horizontal stretch where 0<|a|<1

This means we can eliminate A because that would be a horizontal compression since |a|>1

B seems to work because (1/4(4))^2=1

C does not work because you'll get 2 as your y-value

D does not work because you'd be taking 1/4 of x^2 which would give you 4.

Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.Conducting the Experiment and Keeping an Experiment JournalFollowing the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.Collecting DataAll experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.
