The questions on a test consist of 10 multiple choices, 3 essays, and 9 free responses. If the questions are ordered randomly, what is the probability that the first question is a free response?
Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
10 + 3 + 9 = 22This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
9/22 = 0.409Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.
Increased carbon dioxide may cause global warming by trapping more ____________ in the atmosphere
Answer:
Heat
Explanation:
Carbon dioxide absorbs heat. When there is a large amount of CO2 in the atmosphere, it will hold onto the heat that should be escaping from the atmosphere. As a result, the Earth's overall temperature increases.

The terms that make up each category are: Causes of space race (Fear of being outdone, Sputnik) Causes of the arms race (The hydrogen bomb, fear of being outdone)
What was the space race?The space race was a moment in history, during the Cold War, in which the main world powers of the time, which were the United States and the Soviet Union, began an unofficial competition to demonstrate their superiority.
One of the main topics used to demonstrate superiority was the scientific developments related to the study of outer space
Among the most notable events of this era is the landing on the Moon, the development of hundreds of spacecraft and the development of Sputnik, the space study program of the Soviet Union.
What is the arms race?During the Cold War period, not only studies related to the study of outer space were developed, but other fields were developed.
One of these fields was weapons because the threat of war between the United States and the Soviet Union was always latent. Therefore, each of these nations was responsible for developing the best weapons for the moment in order to demonstrate their superiority over the other.
Among the most important developments are atomic bombs (hydrogen bombs) and ballistic missiles.

How long will it take to go 150,000 meters traveling at 50 km/hour?
Answer:
3 hours
Explanation:
1. Convert 150,000 meters into kilometers - 150,000 ÷ 1000 = 150 kilometres
2. Use the equation: time = distance ÷ speed
3. Substitute in the known values: time = 150 km ÷ 50 km/h = 3 hours
Hope this helps!
Answer:
3 hours
Explanation:
First, you have to convert meters to kilometers.
150,000 meters ⇒ 150 kilometers
Then you divide 150 by 50 and see what you get:
150 ÷ 50=3
It will take 3 hours to go 150,000 meters at 50 km/hour

You own a dance studio. You have assets of $512,667 and equity of $268,964. What is your liabilities total?
The liabilities total of the dance studio is the difference between the asset and the equity
The liabilities total of the dance studio is $243,703
How to determine the liabilities total?The given parameters are:
Assets = $512,667
Equity = $268,964
Liability is the difference between assets and equity.
This is represented as:
liabilities = asset - equity
So, we have:
liabilities = $512,667 - $268,964
Evaluate the difference
liabilities = $243,703
Hence, the liabilities total is $243,703

A 60 g ball is tied to the end of a 70 -cm-long string and swung in a vertical circle. The center of the circle, as shown in the figure,(figure 1) is 150 cm above the floor. The ball is swung at the minimum speed necessary to make it over the top without the string going slack.
The tension in the string an instant before it broke is; T = 0.86 N
What is the Tension in the string?
We are given;
mass of ball; m = 60 g = 0.06 kg
Length of string; L = 70 cm = 0.7 m
Height the ball reaches; h = 150 cm = 1.5 m
From Newton's equation of motion;
v² - u² = 2as
where v = 0 m/s Thus;
-u² = 2(-9.81 * (1.5 - 0.7)
u² = 15.696
u = √15.696
u = 3.17 m/s
Thus, tension is;
T = mu²/L
T = (0.06 * 3.17²)/0.7
T = 0.86 N
