what is the correct decision in a hypothesis if the data produce a t-statistic that is in the critical region?

The correct **decision** in a hypothesis test when the data produces a t-statistic that is in the **critical** **region** is to reject the null hypothesis.

This is because a t-**statics** in the critical region indicates that the differences between the sample mean and the population mean are statistically significant. This means that the data indicates that the null hypothesis is wrong and that the alternative hypothesis is true. In a hypothesis test, the null **hypothesis** is what the researcher is trying to disprove. It is the general statement that suggests that there is no difference between the sample mean and the population mean. The alternative hypothesis is what the researcher is attempting to prove. It suggests that there is a difference between the sample mean and the population mean. Therefore, when the **data** produces a t-statistic that is in the critical region, it indicates that the alternative hypothesis is true. When a t-statistic is in the critical region, it means that the result is statistically significant. This means that the differences between the sample mean and the **population** mean are unlikely to have occurred by chance and that the alternative hypothesis is likely to be true. Therefore, when the data produces a t-statistic that is in the critical region, the correct decision is to reject the null hypothesis and accept the **alternative** hypothesis.

Dena cuts wood for a treehouse. She has 5 pieces of wood left over with the following lengths in centimeters: 12.7, 26 3/10, 15 4/5, 21 1/4, and 19.2.

A. Write and evaluate an expression to find the total length of wood left over.

______________________________________________________________

B. Dena wants to make a birdhouse with the leftover wood. She needs 105 3/5 centimeters of wood for the birdhouse. Write and evaluate an expression to determine how much more wood will be needed.

______________________________________________________________

A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood. We can represent each piece of wood with a fraction and then add all the fractions. The total length of wood can be represented as:

12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)

To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:

12.7 + 26 3/10 = 12.7 + 26.3

15 4/5 = 15 + 0.8

21 1/4 = 21 + 0.25

3/10 = 0.3

4/5 = 0.8

So the expression becomes:

12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45

Therefore, the total length of wood left over is 104.45 centimeters.

B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:

105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15

Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)

To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:

12.7 + 26 3/10 = 12.7 + 26.3

15 4/5 = 15 + 0.8

21 1/4 = 21 + 0.25

3/10 = 0.3

4/5 = 0.8

So the expression becomes:

12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45

Therefore, the total length of wood left over is 104.45 centimeters.

B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:

105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15

Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

Find the measures of each interior angles of a regular polygon having 15 sides

The **measure **of each interior angle of a regular **polygon **having 15 sides is equal to option B: 156°.

A polygon is an enclosed figure composed of more than three straight lines. To find the measure of each **interior angle **of a regular polygon having n sides, we would first find the total sum of interior angles of this polygon. The formula is:

(n-2) × 180°

= (15-2) × 180°

= 13 × 180°

= 2340°

We, here, found that the sum of all interior angles of a **regular **polygon having 15 sides is equivalent to 2340°. Now, to find the measure of each angle, we can divide this sum by the number of **sides **as:

a) The **median **would be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean.

b) The median should be reported as it is a better measure of **central tendency**, as it is not affected by outliers.

a) The **median **is expected to be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the **mean**. The mean is calculated by adding all the values together and dividing by the number of values, and if there are any values that are much lower or higher than the rest, this will affect the mean significantly. The median, however, is the midpoint of the values, so outliers have less of an influence on it.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers. The median is the midpoint of the values, which means that if there are any values that are much lower or **higher **than the rest, it will not affect the median as much as it does the mean. This makes the median more accurate in representing the life expectancy of countries, as it is not skewed by outliers.

Substituting the expression for y into the equation x - y = 18, we get:

x - (x % 10 * 10 + x / 10) = 18

Expanding and simplifying the right side of the equation, we get:

9x = 180 + 10

Dividing both sides of the equation by 9, we get:

x = 20

Since x must be a two-digit number, 20 is not a valid solution. However, we can check the two numbers that are close to 20, which are 18 and 21.

For x = 18, we have y = 81, which is a two-digit number, so 18 is a valid solution.

For x = 21, we have y = 12, which is a two-digit number, so 21 is also a valid solution.

Therefore, the possible two-digit numbers that meet the criteria are 27 and 36.

What point lies on the line with a slope of m=2/3 that passes through the point (-3,-2)?

PLEASE SHOW WORK

**Answer: **y = 2/3x

**Step-by-step explanation:**

This is pretty easy too

the equation for a line is: y = mx + b, where m is the slope and b is the y intercept

y = 2/3x + b, where we need to find b

substituting the point we are given:

-2 = 2/3(-3) + b

-2 = -2 + b

0 = b

so our line is simply:

y = 2/3x

You’ve saved $45, which is 70% of the amount you want to save. What is the total amount you want to save? (round to nearest cent) * *

Rounding this to the nearest cent, the total **amount** that was wanted to be **saved** is $64.29.

To solve this problem, we can set up a **proportion** using the given **information**. Let x be the total amount that was wanted to be saved.

We know that the amount saved ($45) is 70% of the total amount that was wanted to be saved. Therefore, we can write:

45 = 0.7x

To solve for x, we can **divide** both sides by 0.7:

x = 45 ÷ 0.7

x = 64.28571429

The answer to the **problem** is $64.29, rounded to the nearest cent. This means that the **total amount** that was wanted to be saved was $64.29, and 70% of this amount is equal to the amount that was actually saved ($45). To check our work, we can multiply 64.29 by 0.7 to see if it equals 45. When we do this, we get:

64.29 x 0.7 = 45.003, which **rounds** to $45, so our answer is correct.

A triangle is a two-dimensional geometric shape that has three sides and three angles. It is the simplest polygon and is a fundamental building block in many areas of mathematics and science.

The three sides of a triangle can have different lengths and can be of different types, such as equilateral, isosceles, or scalene. An equilateral triangle has three sides of equal length, while an isosceles triangle has two sides of equal length and a third side of a different length. A scalene triangle has all three sides of different **lengths**.

In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Thus, we have:

sin(IHJ) = IJ/IH

Taking the sine of both sides and **substituting **the given values, we get:

sin(23°) = x/2

Multiplying both sides by 2, we have:

x = 2*sin(23°)

Using a **calculator**, we get:

x ≈ 0.83

Therefore, the value of x is approximately 0.8 cm when rounded to the nearest tenth.
