Does the linear function shown by the graph have a positive slope or a negative slope? Does the linear function shown by the table have a positive slope or a negative slope?

Answer:

Percent decrease in area is 72%

Step-by-step explanation:

Percentage decrease is

100% - 14/50 * 100%

100% - 28% = 72%

Therefore, percentage decrease is 72%

The following distributions has a mean that varies

II. The distribution of sample data

III. The sampling distribution of the sample mean

The correct answer is option v) II and III."

Here, we have,

In the context of statistical distributions:

I. The population distribution refers to the distribution of a specific variable within the entire population. The mean of the population distribution which is fixed and does not vary.

II. The distribution of sample data refers to the distribution of a variable within a specific sample. The mean of the sample data can vary from one sample to another.

III. The sampling distribution of the sample mean refers to the distribution of sample means taken from multiple samples of the same size from a population. The mean of the sampling distribution of the sample mean is equal to the population mean, but the individual sample means can vary from sample to sample.

Therefore, the mean varies in both the distribution of sample data (II) and the sampling distribution of the sample mean (III), but not in the population distribution (I).

In Milgram's first study of obedience, the majority of teachers initially complied but refused to deliver more than slight levels of shock.

In Milgram's first study of obedience, participants were assigned the role of 'teacher' and were instructed to administer electric shocks to a 'learner' whenever they answered a question incorrectly. The shocks ranged from mild to severe, with the highest level labeled as 'XXX.' The learner was actually an actor, and no real shocks were administered.

The study found that the majority of teachers initially complied with the experimenter's orders and delivered shocks, but they refused to deliver more than slight levels of shock. This suggests that while they were willing to follow the instructions to some extent, they had moral reservations about causing significant harm to another person.

It is important to note that the study has been criticized for ethical concerns and the potential psychological harm it may have caused to participants. However, it remains a significant contribution to our understanding of obedience and the power of authority figures.

The portion of the sampling distribution in which values are considered too unlikely to have occurred by chance is region of rejection (option b).

The region of rejection is a critical part of the sampling distribution. It is the portion of the distribution in which values are considered too unlikely to have occurred by chance. In other words, if our sample statistic falls within this region, we reject the null hypothesis that the statistic is representative of the population.

The region of rejection is determined by the critical value, which is a value that divides the sampling distribution into the rejection region and the acceptance region.

The critical value is based on the significance level of the test, which is typically set at 0.05 or 0.01. If the sample statistic falls in the region of rejection, it is considered statistically significant, meaning that it is unlikely to have occurred by chance.

So, the correct option is (b).

Step-by-step explanation:

For the entire independent-measures experiment 24 individuals are participated.

Different participants are utilized in each condition of the independent variable in an experimental design known as an independent measures design, or between-groups. This indicates that a different group of participants is present for each condition of the experiment. A research strategy known as an independent measures design uses numerous experimental groups with subjects only being assigned to one group. Throughout the experiment, each participant is solely exposed to one independent variable condition. A drug trial for a novel medicine would serve as an example. This has the benefit of preventing order effects, which occur when participants behave differently as a result of the order in which conditions are done, often as a result of factors like boredom or exhaustion.

We are given the value  t(22) = 5.30, p < .01

So here degree of freedom (df) is 22 and it is independent so there is two samples,

so df= n₁+n₂-2

⇒ 22 =  n₁+n₂-2

⇒ n₁+n₂ = 24.

Thus for the entire experiment 24 individuals are participated.

Answer:

Step-by-step explanation:

The angle between the two vectors A and B is 90°.

The angle between two vectors A and B can be found using the formula:

cosθ = (A⋅B)/(|A||B|)

Where A⋅B is the dot product of the two vectors, and |A| and |B| are the magnitudes of the vectors.

First, we need to find the dot product of the two vectors:

A⋅B = (2)(5) + (3)(2) + (-4)(4) = 10 + 6 - 16 = 0

Next, we need to find the magnitudes of the vectors:

|A| = √(2^2 + 3^2 + (-4)^2) = √(4 + 9 + 16) = √29

|B| = √(5^2 + 2^2 + 4^2) = √(25 + 4 + 16) = √45

Now we can plug these values into the formula:

cosθ = (0)/(√29√45) = 0

θ = cos^-1(0) = 90°

Therefore, the angle between the two vectors A and B is 90°.

Step-by-step explanation:

Answer:

  (a)  $810.45

Step-by-step explanation:

You want the value of an investment of $300 earning 5% interest compounded quarterly for 20 years.

The compound interest formula tells you the value is ...

  A = P(1 +r/n)^(nt)

where P = 300, r = 0.05, n = 4, t = 20.

Using the given parameters in the given equation, you find the account value to be ...

  A = $300(1 +0.05/4)^(4·20) ≈ $810.45

__

Additional comment

The "rule of 72" tells you the account value will approximately double in a number of years equal to 72 divided by the interest rate percentage: 72/5 = 14.4 years. After 20 years, it will be worth more than that doubled amount, $600. This only leaves one reasonable answer choice.

Step-by-step explanation:

Maria's speed is 100km/(12hr and 40min)

Convert the (12hr and 40min) into a value having a single unit (hr or minutes). I'll choose hours: 12hr + (40/60)hr = 12 2/3 hr.

We can now say that Maria's speed is 100km/(12 2/3 hr), or 7.8947 km/hr.

We want to konw how long it will take to go 1600 meters (1 mile) at that speed. 1600 meters = 1.6 km

(TIme)*(Speed) = Distance

(T)*(7.8947 km/hr) = (1.600 km)/(7.8947 km/hr)

T = 0.2027 hours, or (at 60 minutes/hr) 12.16 minutes.

Answer:

w = 59

Step-by-step explanation:

The probability that the arrangement reads xoxox is 0.099

This question involves the advanced probability involving permutations.

So, whenever we have to get the probability of the events occurring together , we multiply their probabilities.

Here, I am denoting probability of x/o in n position as by 'p(x/o)n'.

So, we start from x in the first position, then p(x1)= 3/5=0.6

Now, for getting o in the second position , we have p(o2)= 2/4 =0.5 as the no. of tiles is now reduced to 4.

Similarly , for p(x3)= 2/3= 0.66

p(o4)= 1/2= 0.5

and in the last p(x5) = 1 since its a sure event as we are left with no tile now.

So, the total probability of xoxox is P= p(x1). p(o2).p(x3).p(o4).p(x5)

 = (0.6)x (0.5) x (0.66) x (0.5) x 1 = 0.099

In 42 6/7 minutes the pool will get filed when all 3 pumps work together.

Given,

Time taken by the pump 1 to fill a pool = 50 minutes

Time taken by pump 2 to fill the same pool = 60 minutes

The time taken by pump 3 to drain the pool = 75 minutes

When all the 3 pumps work together, we have to find the time taken to fill the pool;

Here,

In every minute,

Pump 1 fills 1/50 of pool

Pump 2 fills 1/60 of pool

Pump 3 drains 1/75 of pool

That is,

1/50 + 1/60 - 1/75 = 6/300 + 5/300 - 4/300 = 11 - 4 / 300 = 7/300

The time taken = 300/7 minutes = 42 6/7 minutes

Answer:

\(\frac{a}{1 +bc} = x\)

Step-by-step explanation:

In this question, it appears that you need to solve this equation in terms of x.

Beginning with the equation a = x(1 + bc), we must isolate the 'x' variable and make an equation equivalent to 'x'. This can be done by:

a = x(1 + bc)

Divide (1 + bc) from both sides, giving you:
