Answer:

-8/7

Step-by-step explanation:

In fraction form, division means reversed multiply.

You have -3/7 divide 3/8 which also means -3/7 multiply by 8/3, which will be -24/21. The common factor of 24 and 21 is 3 so we simplify both the numerator and denomitator by 3 and the final answer will be -8/7.

The fraction form of 42% is 21/50.

Every fraction's numerator and denominator are split in half by a horizontal bar known as the fractional bar.

The denominator displays the number of pieces into which the whole has been divided. It is situated below the fractional bar in the lower part of the fraction.

The numerator indicates how many portions of the fraction are selected or displayed. It is located at the upper part of the fraction, above the fractional bar.

We have to write 42% into the simplest form fraction.

So, Explicit 42%

42 /100

Now, simplify the fraction by making it in its lowest form

42 /100

2 x 21/ 2x 50 = 21/50

Hence, the fraction is 21/50.

Hypothesis testing provides a systematic approach to examine data and draw conclusions about the population. By following this process, we can gain insights into predictability by evaluating the evidence against the null hypothesis and making informed statistical inferences.

To obtain a sense of predictability, Kelly suggests that we engage in hypothesis testing.

Hypothesis testing is a statistical method used to make inferences or draw conclusions about a population based on sample data. It involves formulating a null hypothesis and an alternative hypothesis, collecting data, and conducting statistical tests to evaluate the evidence against the null hypothesis.

Kelly's suggestion aligns with the idea that hypothesis testing can help us understand and predict outcomes by providing a structured framework for analyzing data and making statistical inferences. Through hypothesis testing, we can assess the significance of relationships, differences, or effects in various fields of study.

Here's a brief overview of the steps involved in hypothesis testing:

Formulate the null hypothesis (H0) and the alternative hypothesis (Ha):

The null hypothesis represents the assumption of no significant difference or relationship, while the alternative hypothesis states the opposite.

Collect and analyze the data:

Gather relevant data through observation, experimentation, or sampling. Perform appropriate statistical analysis to summarize the data and calculate relevant test statistics.

Choose a significance level (α):

The significance level, denoted as α, determines the threshold for rejecting the null hypothesis. It represents the probability of rejecting the null hypothesis when it is actually true.

Calculate the test statistic:

Depending on the nature of the hypothesis and the data, select an appropriate statistical test and calculate the corresponding test statistic.

Determine the critical region and p-value:

The critical region is the range of values for the test statistic that leads to the rejection of the null hypothesis. The p-value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed value under the null hypothesis.

Make a decision:

Compare the calculated test statistic with the critical value or p-value. If the test statistic falls within the critical region or the p-value is smaller than the significance level, reject the null hypothesis. Otherwise, fail to reject the null hypothesis.

Draw conclusions:

Based on the results of the hypothesis test, interpret the findings in the context of the research question and the data. Provide insights into the relationship or effect being tested and assess the predictability or significance of the findings.

In summary, hypothesis testing provides a systematic approach to examine data and draw conclusions about the population. By following this process, we can gain insights into predictability by evaluating the evidence against the null hypothesis and making informed statistical inferences.

Making x the subject of the formula x/y -z=w is

x = y(w+z)

The subject of a formula is the variable which is expressed in terms of the other variable. For example the volume of a cylinder is V = πr^2h.

where V is the volume and r is the radius and h is the height . In the formula V is expressed in term of other variables like radius and height. Therefore V is said to be the subject of the formula

Relating the explanation with the formula x/y -z= w, here w is the subject and we need to make x the subject.

We achieve this by evacuating other variables attached to x

x/y -z= w

add both sides by z

x/y-z+z= w+z

x/y= w+z

multiply both sides by y

x/y×y=(w+z)y

therefore x= y(w+z)

Chin is 0 feet away from the point of tangency.

Since Chin is standing 40 feet away from the center of the round golf course green, and the green has a radius of 40 feet, we can solve for the distance from Chin to a point of tangency using the properties of right triangles.

Let's call the point of tangency "T" and the center of the green "C". Since the tangent line is perpendicular to the radius at the point of tangency, we have a right triangle formed by Chin (vertex A), the point of tangency (vertex T), and the center of the green (vertex C).

Using the Pythagorean theorem (a^2 + b^2 = c^2), where AC is the hypotenuse (c = 40 feet), and TC is one leg (b = 40 feet):

a^2 + (40 feet)^2 = (40 feet)^2

a^2 = 0

a = 0 feet

Answer:

\(x = \frac{ \sqrt{6} }{2} \)

\(y = \frac{3 \sqrt{2} }{2} \)

Step-by-step explanation:

\( \sin(theta) = \frac{opposite}{hypotenuse} \)

\( \cos(theta) = \frac{adjacent}{hypotenuse} \)

\( \tan(theta) = \frac{opposite}{adjacent} \)

theta = 30°

hypotenuse = √6

opposite = x

adjacent = y

\( \sin(theta) = \frac{opposite}{hypotenuse} \)

\( \sin(30) = \frac{x}{ \sqrt{6} } \)

\( \sin(30) \times \sqrt{6} = x\)

\( \frac{ \sqrt{6} }{2} = x\)

\(x = \frac{ \sqrt{6} }{2} \)

\( \cos(theta) = \frac{adjacent}{hypotenuse} \)

\( \cos(30) = \frac{y}{ \sqrt{6} } \)

\( \cos(30) \times \sqrt{6} = y\)

\( \frac{3 \sqrt{2} }{2} = y\)

\(y = \frac{3 \sqrt{2} }{2} \)

The F ratio in a completely randomized ANOVA is a) MSTR/MSE.

The F ratio in ANOVA is a measure of the variability between groups compared to the variability within groups. MSTR (mean square treatment) represents the variability between groups, while MSE (mean square error) represents the variability within groups.

The F ratio is the ratio of MSTR to MSE. A high F ratio indicates that the variability between groups is larger than the variability within groups, suggesting that there is a significant difference between at least two of the group means.

In contrast, a low F ratio suggests that there is little difference between group means, and any observed differences may be due to chance. Therefore, the F ratio is an essential statistic in ANOVA for determining the significance of the observed differences between groups.

Step-by-step explanation:

First, notice how the partially shaded squares fit perfectly into one another (the squares are perfectly cut from corner to corner). Once you match these squares to one another, you can then figure out that they add up to three full squares.

Secondly, measure how many squares there will be in the diagram after adding up the partial squares (resulting in a total of 15).

Finally, calculate the area of one of the squares (2cm x 2cm), which results in 4cm². As you have 15 total squares, multiply 4cm² by that to get the final answer of 60cm².

The angular orientation of lines l and m = horizontal lines

Therefore l and m are parallel lines

The transversal line to lines l and m = Line t

Therefore, we have;

Angles between line t and line l = 1, 2, 3, and 4

The order of arrangement of the angles between line t and line l are from top left in a clockwise order;

1, 3, 4, and 2

Similarly, the order of arrangement of the the angles between the transversal t and the line m are from top left in a clockwise order;

5, 7, 8, and 6

Therefore, we have;

The supplementary angles to ∠4 are;

∠3, ∠2, ∠7, ∠6, and ∠5

∠3 and ∠4, ∠4, and ∠2,  angles on a straight line between lines l and t

∠4 and ∠7 are opposite interior angles (Opposite interior angles are supplementary)

∠7 ≅ ∠6, ∠7 and ∠6 are alternate angles (

∠7 = ∠6 Definition of congruency

∴ ∠4 and ∠6 are supplementary (Transitive property)

∠4 and ∠5 are alternate interior angles (Alternate interior angles are supplementary).

What is Circle ?

In geometry, a circle is a two-dimensional shape consisting of all the points that are equidistant from a given point, called the center. The distance from the center to any point on the circle is called the radius of the circle.

From the given information, we know that V, W, and X are points on a circle with center V, and that VW = WX = 3. We also know that ∠WVX = 90°.

Since WX is a diameter of the circle, it has length equal to twice the radius of the circle. Let r be the radius of the circle, then we have:

VW + WX = 2r

3 + 3 = 2r

r = 3

So the radius of the circle is 3. Since WX is a diameter, its length is 2r = 6. Therefore, the length of ⌢ WX ⌢ expressed as a fraction times π is:6÷π
