Answer:
4Cr + 3O2 -----------> 2Cr2O3
Explanation:
We need to balance both the sides of the equation, that is, number of moles of reactants should be equal to the number of moles of products. So,
4Cr + 3O2 -----------> 2Cr2O3
Comparing the moles of elements, we see that the equation is now completely balanced.

When the plant does photosynthesis, the energy transformation happening is from radiant to chemical.
Which energy transformation happens here?
As you know, in really general words, plants transform the energy that comes from the sun into plant food.
So, let's explain that.
The sun generates radiant energy, this is the energy carried by the electromagnetic waves that come from the sun (mostly, in form of light).
The plant's leaves have the capacity of receiving this energy and absorbing it, storing it, and then being able to use this energy for what the plant needs.
This stored energy would be chemical energy.
Then the transformation is the first one:
radiant to chemical.

In ΔHIJ, i = 400 inches,

�
m∠J=7°. Find the length of h, to the nearest 10th of an inch.
The length of h in ΔHIJ with i = 400 inches, m∠I=155°, and m∠J=7° is approximately 32.3 inches to the nearest 10th of an inch, using the Law of Sines.
What is law of sines?
The Law of Sines, also known as the Sine Rule, is a trigonometric formula used to solve triangles. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. Mathematically, the Law of Sines can be expressed as:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angle measurements.
The Law of Sines can be used to solve for the unknown side lengths or angle measurements of a triangle if you have at least one known side length and its opposite angle measurement, or if you have at least two known side lengths and one of their opposite angle measurements.
Given that i = 400 inches, m∠I=155°, and m∠J=7°, we can use the Law of Sines to solve for the length of h. The Law of Sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
Using this, we have:
sin(155°) / i = sin(7°) / h
Solving for h, we get:
h = i * sin(7°) / sin(155°)
Plugging in the values, we get:
h = 400 * sin(7°) / sin(155°) ≈ 32.3 inches
Therefore, the length of h is approximately 32.3 inches to the nearest 10th of an inch.

when 425 is divided by prime number n, the remainder is 17, what is the remainder when 50 is divided by n ?
helpp pleaasseeee
Answer:
Explanation:
If 425 divided by a prime number n leaves a remainder of 17, we can write the equation 425 = n * q + 17, where q is some integer. If 50 is also divided by n with a remainder of r, we can write the equation 50 = n * s + r, where s is some integer.
Since 425 and 50 both leave the same remainder when divided by n, we can set these two equations equal to each other and solve for r:
425 = n * q + 17
50 = n * s + r
Subtracting 17 from both sides of the first equation gives us:
408 = n * q
Then subtracting 50 from both sides of the second equation gives us:
-8 = n * s - n
Adding n to both sides gives us:
0 = n * s
Since n is a prime number, it must be the case that s = 0. Therefore, r = 50.
So the remainder when 50 is divided by n is 50.

Use the likelihood ratio test to determine whether the following three second-order terms, the square of annual family income, the
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.

4. Why did Althea Gibson likely retire from tennis at the top of her game?
Althea Gibson was a groundbreaking athlete and the first African-American woman to break the color barrier in professional tennis. Between 1956 and 1958 she won 56 titles, including 11 Grand Slam titles. Despite her meteoric rise to stardom, she retired from professional tennis at the age of 29 in 1958, at the peak of her career and with three more consecutive Grand Slam victories under her belt. Her decision to retire at the top of her game came as a shock to many, and a significant loss to the sport of tennis.
This paper seeks to explore the various factors that likely motivated Althea Gibson to retire from tennis at the top of her game. It is argued that Gibson's retirement was motivated by a combination of external and internal factors. Firstly, external factors such as racism and sexism likely played a role in her retirement. Gibson was the first African-American woman to dominate the sport, and was hampered by both racial and gender discrimination. Despite the successes she had achieved, Gibson was still not taken seriously in the eyes of many, which may have motivated her to retire from the sport prematurely.
In addition, Gibson's health may have also been an important factor motivating her retirement. After winning 11 Grand Slams by 1958, Gibson suffered multiple joint injuries, including chronic knee injuries. In addition to physical ailments, Gibson also faced mental and emotional exhaustion from the pressures of being a role model and the expectations that came with it. Furthermore, the racial and gender discrimination she had faced during her career likely added additional strain to an already challenging situation.
Finally, the lack of financial stability and security offered by tennis may have also been a motivating factor in Gibson's retirement. Despite her successes in the sport, Gibson did not have the means to maintain her career and support herself. This lack of support likely weighed heavily on her and may have contributed to her early retirement.
To conclude, Althea Gibson likely retired from tennis at the top of her game due to a combination of external and internal factors. Racism, sexism, her health, emotional exhaustion and the lack of financial stability offered by the sport likely all contributed to Gibson's decision to retire prematurely. While her retirement was a significant loss to the sport, her legacy as the first major African-American woman athlete still resonates today.
The first African-American tennis player, Althea Gibson, most likely left the sport while she was at the pinnacle of her game for a variety of reasons.
Here are a few explanations that could apply, albeit the precise causes can differ:
Pecuniary opportunities are scarce.Limited opportunities for tournaments.A need for a new challenge or burnout.The pursuit of other interests.Thus, these elements shed light on the difficulties she had throughout her career and the causes that might have influenced her choice to leave tennis at the pinnacle of her accomplishment.
