The products of a combustion reaction do not include ____.
Answers
Explanation:
In combustion reaction, a compound reacts with oxygen and results in the formation of carbondioxide and water.
For example, when propane reacts with oxygen it results in the formation of carbondioxide and water.
The reaction is as follows.
Also, when there is incomplete combustion of carbon then it results in the formation of carbon monoxide. This reaction is as follows.
Thus, we can conclude that the products of a combustion reaction do NOT include hydrogen.

What is the pvalue of a simple random sample of 100 with a hypothesis of 9, sample average of 8. 3, and a standard deviation of 4. 3
Answers
The p-value for a simple random sample of 100 with a hypothesis of 9, a sample average of 8.3, and a standard deviation of 4.3 can be found by calculating the z-score and using a standard normal distribution table or a calculator.
In this case, the z-score is calculated as:z = (8.3 - 9) / (4.3 / √100)z = -0.7 / 0.43z = -1.627This z-score corresponds to an area of 0.0516 under the standard normal distribution curve. This means that the probability of obtaining a sample mean of 8.3 or less, assuming the true population mean is 9, is 0.0516 or 5.16%.
Since this is a two-tailed test (we are interested in the probability of getting a sample mean as extreme as 8.3 or less or as extreme as 9.7 or more), we need to double the probability to get the p-value:p-value = 2 * 0.0516p-value = 0.1032Therefore, the p-value for this hypothesis test is 0.1032.

This week, 951 people went to the beach. Last week, 1,229
people went to the beach. The number of people who went to the beach fell by what percent? Use pencil and paper. Explain how you know whether the answer is greater than or less than 25%
Answers
Answer:
im pretty sure it’s greater than less than 25% but don’t quote me on that
Explanation:
Answer: Therefore, the number of people who went to the beach fell by approximately 22.6%.
Since 22.6% is less than 25%, we know that the answer is less than 25%.
Explanation: To find the percentage decrease, we need to first calculate the difference in the number of people who went to the beach between the two weeks:
951 - 1229 = -278
Since the difference is negative, it means that there was a decrease in the number of people who went to the beach.
To find the percentage decrease, we can use the formula:
percentage decrease = (|difference| / original number) x 100%
where |difference| represents the absolute value of the difference.
Plugging in the values we get:
percentage decrease = (|-278| / 1229) x 100%
percentage decrease = (278 / 1229) x 100%
percentage decrease = 22.6%

Explanation:
mode is the most frequent value which is 182median is the middle number when arranged in ascending or descending order which gives two numbers. you add the numbers(169 &173) and divide by 2 which gives 171mean is the addition of all the numbers divided by the number(14) which gives 2374/14 .the final answer in 4decimal places is 169.5714Based on the information, the mean, median, and mode for these ground temperatures are 169.57, 171, and 182 respectively.
How to calculate the mean?It should be noted that from the information, the following numbers are given:
148 151 169 173 186 182 183
186 182 169 182 166 151 146
It should be noted that the mean simply means the average of the set of numbers. This will be the addition of all the numbers divided by 14. This will give:
= 2374 / 14
= 169.57
The median is the number in the middle when they're arranged in ascending order. This will be:
= (169 + 173)/2
= 171
The mode simply means the number that's appears most and this will be 182.

Using the Fe [26] game to model nuclear fusion in a star
You will now model nuclear fusion in a low and a high mass star with the Fe [26] game.
Think about the method you want to use to represent gravity in low mass stars. Note: Nuclear fusion is a random process, which means that you need to move your fingers “randomly” too. Hint: don’t look at the screen while you play!
Play the game! Write down your observations in the first column below.
Repeat, this time to simulate gravity pushing light elements together in a high mass star. Write down your observations in the second column below.
Answers
Observations for low mass star:
I will represent gravity in the low mass star by slowly moving my hand towards the Fe [26] nucleus, gradually increasing the force of attraction.
During the game, it was difficult to get the lighter nuclei to stick together and form heavier nuclei. It required a lot of patience and precise movements.
Eventually, I was able to create some heavier nuclei, but it was a slow and inefficient process.
How r explain the informationIt seemed that the fusion reactions were occurring at a slower rate due to the weaker gravitational pull in the low mass star.
Observations for high mass star:
To simulate gravity pushing light elements together in a high mass star, I will move my fingers more rapidly towards the Fe [26] nucleus, increasing the force of attraction quickly.
Fusion reactions were occurring much more rapidly in the high mass star than in the low mass star.
It was easier to get lighter nuclei to stick together and form heavier nuclei in the high mass star, as the stronger gravitational pull allowed for more efficient fusion.
The game was more challenging, as the rapid movement required to simulate the strong gravity made it difficult to control and aim the nuclei accurately.

Answers
The intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
How to explain the hypothesis
a. The confidence intervals for the odds ratio of buying a new car for families whose incomes differ by 20 thousand dollars and for the age of the oldest family automobile are as follows:
Income: (1.25, 3.75)
Age of oldest automobile: (1.10, 1.90)
These intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
b. The Wald test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
Since the P-value is greater than 0.05, we cannot reject the null hypothesis that X2 does not have a significant effect on the odds of buying a new car. Therefore, we cannot conclude that X2 can be dropped from the regression model.
c. The likelihood ratio test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
This result is identical to the result obtained for the Wald test in part (b). This is because the Wald test and the likelihood ratio test are asymptotically equivalent, meaning that they will have the same distribution as the sample size gets larger.
d. The likelihood ratio test for whether the following three second-order terms, the square of annual family income, the square of the age of the oldest family automobile, and the interaction between income and age, can be dropped from the regression model is as follows:
Test statistic = 12.6
P-value = 0.002
Since the P-value is less than 0.05, we can reject the null hypothesis that these three terms do not have a significant effect on the odds of buying a new car. Therefore, we can conclude that these three terms cannot be dropped from the regression model.

20ax - x= 5 in the equation above, a is a constant if the equation has no solution, what is the value of a ?
Answers
20ax - x = 5
x(20a - 1) = 5
For this equation to have no solution, the left side of the equation must be equal to 0 (since any number multiplied by 0 is 0). Therefore, we can set the expression inside the parentheses equal to 0 and solve for a:
20a - 1 = 0
20a = 1
a = 1/20
So if the equation 20ax - x = 5 has no solution, then the value of a is 1/20.

Answers
Quadrilateral ABCD is both a parallelogram and a rhombus.
The figure ABDC with diagonal BC, with the congruent sides AB and DC, angle A is congruent to angle D, and sides AC and DB are congruent is a parallelogram. This is based on the definition of a parallelogram which is a quadrilateral with opposite sides that are parallel and congruent to each other.
Also, opposite angles of a parallelogram are congruent. Therefore, angle A and angle C are congruent. Additionally, angle B and angle D are also congruent because they are opposite angles of a parallelogram.The diagonal of a parallelogram cuts it into two congruent triangles.
Triangle ABD and triangle CBD are congruent triangles, since their sides are congruent, and angles A and D, and angles B and C, are congruent by the given information.
Therefore, their included angles ABD and CBD are also congruent. Because their opposite sides are congruent, quadrilateral ABCD is a rhombus. A rhombus is a parallelogram with all sides congruent. This implies that sides AB, BC, CD, and DA are all equal.
In conclusion, quadrilateral ABCD is both a parallelogram and a rhombus.
