The question that Diondra would ask that does not allow for variability is A. Which movie did her best friend like the most?

The other three questions ("How many awards did each movie win?", "What is the total dollar amount that each movie made from ticket sales?", and "How many weeks did each movie play in the theater?") all offer metrics by which a movie's popularity could be measured, and those measurements could vary from movie to movie.

However, the question about her best friend's favorite movie depends solely on the opinion of one individual, not a variable measure, and therefore doesn't allow for variability.

According to Cohen's guidelines, a "large" effect size is generally considered to be Cohen's d of 0.8 or higher. However, it is important to consider the specific field and context of the research when interpreting effect sizes.

According to Cohen's guidelines, an effect size can be classified as small, medium, or large. Cohen's d is a commonly used effect size measure, which is calculated by taking the difference between the means of two groups and dividing it by the pooled standard deviation.

The interpretation of what constitutes a "large" effect size can vary across different fields of study. However, Cohen proposed general guidelines for interpreting effect sizes:

Small Effect Size: Cohen's d around 0.2

A small effect size suggests that there is a noticeable, but not substantial, difference between the groups or conditions being compared. It is typically considered a modest effect.

Medium Effect Size: Cohen's d around 0.5

A medium effect size indicates a moderate difference between the groups or conditions. It is generally considered a meaningful effect that is noticeable and important.

Large Effect Size: Cohen's d around 0.8 or higher

A large effect size represents a substantial and substantial difference between the groups or conditions being compared. It is considered a strong and robust effect that is often considered highly significant.

It is important to note that these guidelines are not set in stone and can vary depending on the field of study, the specific research question, and the context of the research. Additionally, effect sizes can also be influenced by factors such as the measurement scale used, the specific statistical analysis, and the sample size.

In summary, according to Cohen's guidelines, a "large" effect size is generally considered to be Cohen's d of 0.8 or higher. However, it is important to consider the specific field and context of the research when interpreting effect sizes.

Approximately 99.7% of scores lie in the shaded region.

We have,

The empirical rule, also known as the 68-95-99.7 rule, provides an estimate of the percentage of scores that lie within a certain number of standard deviations from the mean in a normal distribution.

According to this rule:

Approximately 68% of scores lie within 1 standard deviation of the mean.

Approximately 95% of scores lie within 2 standard deviations of the mean.

Approximately 99.7% of scores lie within 3 standard deviations of the mean.

Now,

In the given scenario, the shaded region represents the area between -2 and 3 standard deviations from the mean on the x-axis.

This encompasses the area within 3 standard deviations of the mean.

And,

Since 99.7% of scores lie within 3 standard deviations of the mean, we can estimate that approximately 99.7% of scores lie in the shaded region.

Therefore,

Approximately 99.7% of scores lie in the shaded region.

84.13% of the printing jobs will be acceptable.

The new standard deviation required to achieve a minimum of 95% of jobs acceptable is 0.121.

The darkness of the print is measured quantitatively using an index. If the index is greater than or equal to 2.0 then the darkness is acceptable. Anything less than 2.0 means the print is too light and not acceptable. The machines print at an average darkness of 2.2 with a standard deviation of 0.20.

The mean of the darkness of the print is µ = 2.2 and the standard deviation is σ = 0.20.Therefore, the z-score can be calculated as; `z = (x - µ) / σ`.The index required for acceptable prints is 2.0. Thus, the percentage of prints that are acceptable can be calculated as follows;P(X ≥ 2.0) = P((X - µ)/σ ≥ (2.0 - 2.2) / 0.20)P(Z ≥ -1) = 1 - P(Z < -1)Using the standard normal table, P(Z < -1) = 0.1587P(Z ≥ -1) = 1 - 0.1587= 0.8413.

To find the new standard deviation, we can use the z-score formula.z = (x - µ) / σz = (2.0 - 2.2) / σz = -1Therefore, P(X ≥ 2.0) = 0.95P(Z ≥ -1) = 0.95P(Z < -1) = 0.05Using the standard normal table, the z-score value of -1.645 corresponds to a cumulative probability of 0.05. Hence,z = (2.0 - 2.2) / σ = -1.645σ = (2.0 - 2.2) / -1.645= 0.121.

The selection can be made in 15 different ways, taking into account the distinct combinations of a boy and a girl from the given group of 5 boys and 3 girls.

To determine the number of ways a boy and a girl can be selected from a group of 5 boys and 3 girls to attend a conference, we can use the concept of combinations.

The number of ways to choose one boy from 5 boys is 5C1, which is equal to 5. Similarly, the number of ways to choose one girl from 3 girls is 3C1, which is equal to 3.

To select one boy and one girl, we need to multiply the number of ways to choose a boy and a girl together. Using the multiplication principle, we multiply the number of choices for each category: 5C1 * 3C1 = 5 * 3 = 15.

Therefore, there are 15 ways to select a boy and a girl from the given group to attend the conference.

Each combination represents a unique pair consisting of one boy and one girl. For example, if the boys are labeled as B1, B2, B3, B4, and B5, and the girls are labeled as G1, G2, and G3, the possible pairs could be (B1, G1), (B1, G2), (B1, G3), (B2, G1), (B2, G2), and so on, up to (B5, G3).

Note angle sum higher than 180 due to rounding inaccuracies

Step-by-step explanation:

(a) <C == 180 - (40 + 60) == 80 (Interior angles on triangle have sum of 180 degrees)

side a = (8*sin(40))/sin(60) == 5.938cm by law of sines

side c = (8*sin(80))/sin(

60) == 9.097cm by law of sines

(b) unsure

(c) b^2 = 17^2 + 11^2 - 2(17)(11)cos(104) --> Law of cosines

b^2 = 289 + 121 - 2(187)cos(104)

b^2 = 400 - -90.479

b^2 = 490.479

b = 22.147 cm

sin(A)/17cm = sin(104)/22.147cm

A = arcsin((17/22.147)*sin(104))

Answer: The acceleration of the car is -6 m/s²

Step-by-step explanation:

The acceleration of the car can be found by using the given below equation:

Acceleration = (final velocity - initial velocity) / time

Given:

Initial velocity (u) = 30 m/s

Final velocity (v) = 0 m/s

Time (t) = 5 seconds

Putting the values in the equation:

acceleration = (0 - 30) m/s / 5 s

acceleration = -30 m/s / 5 s

acceleration = -6 m/s²

Therefore, the acceleration of the car is -6 m/s² (negative sign indicates deceleration).

The machine's resale value Garland Mills purchased in 4 years from now will be; $353,049

We are told that the machines present resale value is $420000. Now formula for future value is;

Future value = present value * exp(cx)

Thus;

$420,000 = $500,000 * exp(2c)

420000/500000 = exp(4c)

2c = In(420000/500000)

c = -0.087

Future value = present value * exp(cx)

Future value = $500,000 * exp(-0.087 * 4)

To find:

The angle classification of the given triangle.

Solution:

Let a,b,c are the three sides of a triangle ABC, where c is the longest side.

1. Triangle ABC is acute, if \(c^2<a^2+b^2\).

2. Triangle ABC is acute, if \(c^2=a^2+b^2\).

3. Triangle ABC is acute, if \(c^2>a^2+b^2\).

The sum of square of two smaller sides is

\(3^2+5^2=9+25\)

\(3^2+5^2=34\)

In the given triangle 7 cm is the longest sides. So,
