The directionality of the alternative hypothesis and the support offered by the sample data determine whether the null hypothesis is likewise rejected at the 5% level of significance for a related one-tailed test.

When the two-tailed test rejects the null hypothesis, it means that the sample data, regardless of how we look at it, support the null hypothesis.. A one-tailed test, however, simply considers the evidence in one way. As a result, the null hypothesis should be used if the sample data only show evidence that the alternative hypothesis is true in one direction (for example, greater than).

Both methods are valid and result in the same answer.

In mathematics, the term "congruent" refers to figures and shapes that can be flipped or rearranged to match up with other ones. These forms can be mirrored to produce related shapes.

If two shapes are similar in size and shape, they are congruent. We can also state that if two shapes are congruent, then their mirror images are identical.

Both students are correct.

Student A divides the Z into 4 congruent right triangles and 2 rectangles. The area of the right triangles is found by multiplying the base and height and dividing by 2, while the area of the rectangles is found by multiplying the length and width. Adding the areas of all the shapes together, the total area of the Z is 32 square units.

It will take approximately 29 days for the ant population to drop below 250.

The logarithmic function to the base e is called the natural logarithmic function and it is denoted by loge.

f(x) = loge x

To find out how many days it will take for the ant population to drop below 250, we need to solve for the value of t in the equation:

A(t) = [tex]45000*(0.271)^t[/tex]< 250

We can start by simplifying the equation:

[tex]45000*(0.271)^t[/tex]< 250

[tex](0.271)^t[/tex] < 250/45000

[tex](0.271)^t[/tex]< 0.00555556

Next, we can take the natural logarithm of both sides to isolate t:

ln[[tex](0.271)^t][/tex] < ln(0.00555556)

t*ln(0.271) < ln(0.00555556)

t > ln(0.00555556) / ln(0.271)

Answer:

[tex]4\sqrt{3}[/tex] cm

Step-by-step explanation:

We can use the Pythagorean Theorem to answer this question. Recall that the Pythagorean Theorem is:

[tex]a^2+b^2=c^2[/tex]

where a is the length of a leg, b is the length of the other leg, and c is the length of the hypotenuse.

We are given the hypotenuse (8 cm) and one of the legs (4 cm). Substitute the values and solve for the unknown.

[tex]a^2+b^2=c^2=\\4^2+b^2=8^2=\\16+b^2=64=\\b^2=48=\\b=\sqrt{48} =\\b=\sqrt{16}*\sqrt{3} =\\ b=4\sqrt{3}[/tex]

Therefore, the measure of the other leg is equal to [tex]4\sqrt{3}[/tex] cm.

Hence, it is expected that 14 flights will arrive on time out of the 100 trials of this experiment.

The probability of an occurrence is a number used in mathematics to describe how likely it is that the event will take place. In terms of percentage notation, between 0% and 100% it is expressed as a number between 0 and 1, or . The higher the likelihood, the more likely it is that the event will take place.

 when we refer to an experiment or trial, we mean a random experiment. When difference  between a trial and an experiment, think of the experiment as a larger entity created by the fusion of several trials.

Unless otherwise stated,A trial is any specific outcome of a random experiment. In other words, a trial of the experiment is what we call when we conduct an experiment.

according to question, the number of on-time flights in 100 trials as a binomial random variable with parameters n = 100 (the number of trials) and p (the chance of success, i.e., a flight being on time), presuming that the probability of a flight being on time is the same in all trials.

The expected number of on-time flights in 100 trials is E(X) = np if the same of a flight being on time is p. Given that E(X) = 15, we determine p ,

E(X) = n p = 15 n = 100

p = [tex]\frac{E(X)}{n} = \frac{15}{100}[/tex] = 0.15

Therefore, it is probability that 0.15 %of flights will arrive on time.

To determine the expected  number of trials from a total of 100

Using the probability mass function of the binomial distribution, we can get the expected probability of trials out of 100 that result in precisely 15 flights departing on time:

[tex]P(X = 15)=(100 choose 15) * 0.15^{15} * 0.85^{85}[/tex]

We can calculate this 0.144 get  using a calculator.

therefore it is expected that 14 flights will arrive on time out of the 100 trials of this experiment. It should be noted that while this is an expected value, random fluctuation may cause the actual number of on-time flights in each trial to deviate somewhat from this figure.

The product of 13.5 and 12.1 using a regrouping strategy is 163.35.

To begin with, we can start by breaking down each number into its place value components, which are the ones, tenths, and hundredths places. We can represent 13.5 as 13 + 0.5 and 12.1 as 12 + 0.1.

So, we can rewrite 13.5 as (10 + 3) + 0.5 and 12.1 as (10 + 2) + 0.1. Now, we can use the distributive property of multiplication to multiply 13.5 by 12.1 as follows:

13.5 x 12.1 = (10 + 3 + 0.5) x (10 + 2 + 0.1)

= 10 x 10 + 10 x 2 + 10 x 0.1

+ 3 x 10 + 3 x 2 + 3 x 0.1

+ 0.5 x 10 + 0.5 x 2 + 0.5 x 0.1

Next, we can simplify each of these products by multiplying the numbers in the ones and tenths places separately, and then adding the results. For example, 10 x 10 = 100, 10 x 2 = 20, 10 x 0.1 = 1, 3 x 10 = 30, and so on.

So, continuing from the previous step, we get:

13.5 x 12.1 = 100 + 20 + 1

+ 30 + 6 + 0.3

+ 5 + 1 + 0.05

Finally, we can add up all these products to get the final answer:

13.5 x 12.1 = 163.35

Based on the p-value of 0.21,  the researcher should conclude that option (D) The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time.

A p-value of 0.21 means that if the null hypothesis (the hypothesis that there is no significant difference between groups or no significant relationship between variables) is true, there is a 21% chance of obtaining a test statistic as extreme as the one observed or more extreme.

In general, a p-value of 0.05 or less is considered statistically significant, which means that the probability of obtaining a test statistic as extreme as the one observed or more extreme is less than 5% if the null hypothesis is true. In this case, since the p-value is greater than 0.05, the null hypothesis cannot be rejected and the result is not statistically significant.

Option A is incorrect because multiplying the p-value by 2 assumes a two-tailed test, which may not be the case. Option B is incorrect because a significance level of 0.5 is not commonly used in hypothesis testing.

Option C is incorrect because the statement that "if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time" is not based on the p-value. Option E is incorrect because subtracting the p-value from 1 assumes a one-tailed test, which may not be the case.

line n (and if it is parallel or not) has nothing to do with this solution. it is only there to confuse us.

the sum of all angles around a single point on one side of a line is 180° (because the line can act as the diameter of a circle with the point being is center, and a half-circle stands for 180°).

so,

180 = (6x - 19) + (8x + 3)

The second time when harry feel like consuming 17 kg of sheep after he wakes up is equal to 39.7 hours ( round to nearest tenth of an hour).

Function is equal to

H (t) = 12 sin (2/24t) +15

Where  H(t) models the weight of sheep in kg that Harry like to swallow in 't' hours after wakes up.

't' in radians.

Harry wants to consumes 17kg

⇒ H(t) = 17 for t.

Substituting the given expression for H(t), we get,

⇒ 12 sin(2/24 t) + 15 = 17

⇒ 12 sin(2/24 t) = 2

⇒ sin(2/24 t) = 1/6

⇒ 2/24 t = sin^(-1)(1/6)

We know that sin^(-1)(1/6) = 0.167

Substitute the value we get,

⇒ t = 12 × 0.167

⇒ t = 2.004 radians

This gives us the first time after Harry wakes up that he feels like consuming 17 kg of sheep.

For the second time,

Add one full period to the first time, since the function H(t) has a period of 12π/2 = 6π.

The second time is,

t = 2.004 + 6π

  = 2.004 + 6×3.14

 = 20.844 radians

To round to the nearest tenth of an hour,

Since there are 12 hours in a full revolution.

Convert radians to hours by dividing by 2π and then multiplying by 12.

t = 20.844/(2π) ×  12

 = 3.31 × 12 hours

 = 39.69

  = 39.7 (rounded to the nearest tenth)

The only solution to the system of linear inequalities is (3,2).

Inequality in mathematics is a mathematical statement that two values are not equal. It is usually represented by an inequality sign, such as > or <. Inequality can refer to both numerical and geometric relationships. It is an important concept in all areas of mathematics, from algebra and geometry to calculus and beyond. Inequality can also be used to describe the relationship between two variables, such as the size of an object and its weight.

A. (3, 2)
B. (2, 4)

The ordered pair (3,2) is the only solution to the system of linear inequalities. To check this, we can substitute the values of x and y into the equations. For (3,2), when x = 3 and y = 2, we have x + 2y = 7 and 3x - 4y = 4. As both of these equations are less than the given inequalities, (3,2) is a valid solution. For (2,4), when x = 2 and y = 4, we have x + 2y = 10 and 3x - 4y = -4. The first equation is equal to the given inequality,

while the second equation is less than the given inequality, so the ordered pair (2,4) is not a valid solution. Similarly, for (5,1), when x = 5 and y = 1, we have x + 2y = 7 and 3x - 4y = 11. Again, the first equation is less than the given inequality and the second equation is equal to the given inequality, so (5,1) is not a valid solution. Therefore, the only solution to the system of linear inequalities is (3,2).
