Cohen's conventions for interpreting d, this effect is small. Therefore, the correct answer is a. small.

According to Cohen's conventions for interpreting the effect size (d), the effect described in the study is considered "small." Cohen's conventions provide a general guideline for categorizing the magnitude of an effect size.

In this case, the effect size (d) is calculated to be 0.02. Cohen's conventions typically classify effect sizes as follows:

Small effect: d = 0.2

Medium effect: d = 0.5

Large effect: d = 0.8

Since the effect size of 0.02 is significantly smaller than the threshold for a small effect (0.2), it falls into the "small" category. This means that the difference in the number of words uttered per day between men and women, as reported in the study, is relatively small or negligible in practical terms.

Therefore, the correct answer is a. small.

Using f -statistic value relationship with population variation , the ratio of population variance lie in interval [0.1008,2.021].

0.1008 <σ₁²/σ₂²< 2.021

So, the correct option is option( d).

A professor wants to compare the variances of scores between two sections of classess.

we have

sample size for first class score (n₁) = 13

sample size for second class score (n₂) = 16

confidence interval is 99%

sample variance of first sample (s₁²) = 203.25

sample variance of second sample (s₂²)= 474.42

Using the relationship

( s₁² /s₂² )/F₁₋ₐ/₂ < σ₁²/σ₂²< ( s₁²/s₂²)/Fₐ/₂

a = 0.005

F at (1- a/2) or F₀.₉₉₅, ₁₃,₁₆= 4.249

F at a/2 or F₀.₀₀₅,₁₃, ₁₆ = 0.2118

plugging all known values in above formula

=> ( 203.25/474.42)/4.249<σ₁²/σ₂²< (203.25/474.42)/0.2118

=> 0.1008 <σ₁²/σ₂²< 2.021

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

Step-by-step explanation:

Given that :

Adult admission :

Adult (a) = $3

Children (b) =$2

60 tickets were sold :

a + b = 60 - - - (1)

Cost of tickets sold :

3a + 2b = 160 - - - (2)

From (1):

a = 60 - b

3(60 - b) + 2b = 160

180 - 3b + 2b = 160

180 - b = 160

180 - 160 = b

20 = b

Number of adults :

a = 60 - b

a = 60 - 20

a = 20

Synchronization using locks or mutexes and Message passing and communication protocols aim to provide a controlled and synchronized access to shared resources.

Two methods that can help remove race conditions are:

1. Synchronization using locks or mutexes:

This method involves using synchronization primitives such as locks or mutexes to enforce mutual exclusion.

By acquiring a lock before accessing shared resources or critical sections of code, multiple threads or processes can be serialized, ensuring that only one thread/process can access the resource at a time. This prevents race conditions by preventing concurrent access to shared resources and maintaining the integrity of the data. However, it can introduce performance overhead and may lead to potential deadlocks if not implemented carefully.

2. Message passing and communication protocols:

In this method, instead of sharing data directly, processes or threads communicate with each other through message passing mechanisms and follow specific communication protocols. The shared resources are encapsulated within the processes/threads, and data access is controlled through message passing. This ensures that only one process/thread can access the shared resource at a time, eliminating the possibility of race conditions. This method promotes a more structured and controlled approach to data sharing and can be particularly useful in distributed systems. However, it may introduce complexity in the system design and require additional overhead for message passing.

Answer:

1. (10, -⁸/₃)

2. (2, ⁸/₃)

3. (12, -4)

Step-by-step explanation:

I will do the first 3 as examples.

1. Y is ⅔ of the distance from X to Z.

Y − X = ⅔ (Z − X)

The x-coordinate of Y is:

x − -6 = ⅔ (18 − -6)

x + 6 = ⅔ (24)

x + 6 = 16

x = 10

The y-coordinate of Y is:

y − 8 = ⅔ (-8 − 8)

y − 8 = ⅔ (-16)

y − 8 = -³²/₃

y = -⁸/₃

Y is at (10, -⁸/₃).

2. The ratio of XY to YZ is 1:2.

(Y − X) / (Z − Y) = 1 / 2

Cross multiply.

2 (Y − X) = Z − Y

The x-coordinate of Y is:

2 (x − -6) = 18 − x

2x + 12 = 18 − x

3x = 6

x = 2

The y-coordinate of Y is:

2 (y − 8) = -8 − y

2y − 16 = -8 − y

3y = 8

y = ⁸/₃

Y is at (2, ⁸/₃).

3. Y is ¼ of the distance from Z to X.

Y − Z = ¼ (X − Z)

The x-coordinate of Y is:

x − 18 = ¼ (-6 − 18)

x − 18 = ¼ (-24)

x − 18 = -6

x = 12

The y-coordinate of Y is:

y − -8 = ¼ (8 − -8)

y + 8 = ¼ (16)

y + 8 = 4

y = -4

Y is at (12, -4).

The true statement about the function of area of by rectangle and width of rectangle are:

The correct answer option is options A and D

A rectangle is a quadrilateral having opposing sides parallel and four right angles.

At point (x, y) = (10, 100) the area is maximum.

This means that the area of the rectangle is maximum when width is 10m.

If the width of the rectangle is more than 10m, the area reduces or decreases.

Therefore, the statement Greater width relates to greater area as long as the width is more than 10 m is false.

The statement "To get the greatest area, the width should be 20" is false.

The correct option is b) 5 meters per second squared. Note that the unit "newton" represents one kilogram meter per second squared (1 N = 1 kg m/s²).

To calculate the acceleration of the 6 kg object when a force of 30 newtons is applied, we can use the formula f=ma and rearrange it to solve for acceleration: a=f/m. Plugging in the values, we get a = 30 N / 6 kg = 5 meters per second squared (m/s^2). Therefore, the correct answer is option b), 5 meters per second squared. It's important to note that acceleration is a measure of how quickly the velocity of an object is changing, and it is expressed in units of distance per time squared (m/s^2 in this case). Using the formula for force, F = ma, where F is force, m is mass, and a is acceleration, we can calculate the acceleration of the 6 kg object acted upon by a 30 N force. First, rearrange the formula to solve for acceleration: a = F/m. Then, plug in the given values: a = (30 N)/(6 kg). The acceleration of the object is 5 meters per second squared (5 m/s²). So, the correct answer is option b) 5 meters per second squared. Note that the unit "newton" represents one kilogram meter per second squared (1 N = 1 kg m/s²).

After 5 people did not come, the amount each person had to pay = 100/10 + 1 = $11 each person paid after.

Let the amount that each person had to pay before 5 people did not come be x.

Therefore, before 5 people did not come, the number of people who came to the party = x + 5.Therefore, the total amount raised is 100 = x(x + 5).

Thus, x² + 5x - 100 = 0. We solve for x to find x = 10 or x = -15. We discard x = -15 as the answer must be positive.

Therefore, x = $10 is the amount each person had to pay before 5 people did not come.

Therefore, the total number of people who came to the party = 10 + 5 = 15.Now, after 5 people did not come, the total number of people who came to the party = 10. Also, the total amount raised was $100.

Therefore, after 5 people did not come, the amount each person had to pay = 100/10 + 1 = $11 each person paid after.
