Choose impossible,unlikely,as likely as not, or certain to describe the event. The spinner lands on numbers 2,3,or 4.
The event can be unlikely.
What is Probability?A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.
As per the given data:
We have to find out whether the event that a spinner lands on the numbers 2, 3, or 4 is impossible,unlikely,as likely as not, or certain.
The event cannot be impossible because there is a chance that it might actually stop on any of the three numbers 2, 3, or 4.
The event can be unlikely because it's not confirmed that it will always stop on any of the three numbers 2, 3, or 4.
The event cannot be as likely as not because the probability of the event happening and not happening is not the same.
The event cannot be certain because it's not confirmed that it will always stop on any of the three numbers 2, 3, or 4.
Hence, The event can be unlikely.

Step-by-step explanation:
In January, a store sold a pack of collectible cards for $1.75. In February, they sold the same pack of collectible cards for $1.89. What is the percent of the increase?
Answer:
8%
Step-by-step explanation:
Step 1: Find the difference (increase) between the two costs
[tex]\$1.89 - \$1.75\\\\= 1.89 - 1.75\\\\= 0.14[/tex]
Step 2: Divide the increase by the original cost
[tex]0.14 \div 1.75\\\\\frac{0.14}{1.75} \\\\= 0.08[/tex]
Step 3: Convert the answer to percent
[tex]\frac{0.08}{1} \times \frac{x}{100}[/tex]
Cross multiply
[tex]0.08 \times 100\\\\= 8 \\\\= 8\%[/tex]
Therefore, 8% is the percent increase.

ota
Answer:
160 m²
384 m²
Step-by-step explanation:
The area of a trapezium is given by :
A = 1/2(a + b)h
h = height ; a and b = lengths
From the diagram :
A = 1/2(12 + 20)10
A = 1/2(32)10
A = 16 * 10
A = 160 m²
2.)
Area of parallelogram = base * height
Base = 24 ; h = 16
A = 24 * 16
A = 384 m²

Part A: Ask Questions
The first stage in designing your paper is to make a list of questions to guide you as you research the
topic. Here are some sample questions to get you started:
What are the biotic and abiotic components of ocean ecosystems?
• What types of resources do humans get from the ocean?
• What types of human activities negatively affect ocean ecosystems?
• Which activity would you like to focus on for this paper?
How does this activity negatively affect ocean ecosystems?
• What are some of the solutions people have come up with to address this problem?
What are the benefits of these solutions? What are the drawbacks?
• Is any one solution clearly the best overall solution, or is each solution effective for different
problems?
• How can ordinary citizens make a difference to this problem?
• How can I communicate the problem to citizens and encourage them to take action?
Once you've decided on your focus for the research paper, write three additional questions that you
about your specific area of focus.
.
Answer:
Biotic factors include plants, animals, and microbes. Abiotic factors include the amount of sunlight, amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature.Humans mine the ocean for minerals such as salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt which can be found in the deep sea and is also drilled for crude oil.Fisheries may overfish some populations and lead them near extinction or some fish practices also damage the environment. Harmful chemicals can easily flow into rivers or into the ocean. Oil spills can coat beaches, smother ocean plant life, and kill a variety of birds, fish, and sea mammals.Fishing PracticesBottom trawling and cyanide fishing both kill more than just fish. Cyanide fishing involves spraying or dumping cyanide onto reefs to stun and capture live fish. This also kills coral polyps and degrades the reef habitat. But bottom trawling destroys far more ocean habitat than any other fishing practice. Large weighted nets are dragged across the ocean floor destroying enormous amounts of fragile seafloor habitats.Ocean habitat restoration would probably be the best as that is where most of the damage is being delt. Many projects are now seeking to restore marine habitats, such as mangroves and seagrass.The easiest way for everyday humans to protect ocean life is to stop using single-use plastics. Many countries have already taken steps to ban items like straws, drink stirrers, and cotton buds.We should look after the Ocean and therefore our planet, not just because it keeps us alive, but because it is our inherent duty to do so.1. Where do microplastics come from?2. What advancements are being made in recycling plastics?3. Will coral reefs survive the recent global bleaching events?Biotic variables incorporate plants, creatures, and organisms. Abiotic components incorporate the sum of daylight, oxygen, and supplements broken up within the water, vicinity to arrive, profundity, and temperature. Humans mine the sea for minerals such as salt, sand, rock, and a few manganese, copper, nickel, press, and cobalt which can be found within the profound ocean and is additionally penetrated for unrefined oil. Fisheries may overfish a few populaces and lead them close termination or a few angles hones to harm the environment. Destructive chemicals can effectively stream into streams or the sea. Oil spills can coat shorelines, cover sea plant life, and slaughter an assortment of winged creatures, angles, and ocean mammals. Fishing Practices Bottom trawling and cyanide angling both murder more than fair angle. Cyanide angling includes showering or dumping cyanide onto reefs to shock and capture live angle. This too murders coral polyps and debases the reef environment. But foot trawling crushes distant more sea living space than any other angling practice

The value are equivalent to the fraction below is 3^2, the correct option is F.
What is a fraction?
A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
3^5/3^8
Now,
A. 3^-3: This is equivalent to 1/3^3 by moving the negative exponent to the denominator. Then we can simplify 1/3^3 to 1/27 by multiplying 3 by itself 3 times. This is not equivalent to 3^5 / 3^8, since 1/27 is not equal to 3^-3.
B. (1/3)^2: This is equivalent to 1/3^2 by applying the exponent to the numerator and denominator. Then we can simplify 1/3^2 to 1/9 by multiplying 3 by itself 2 times. This is not equivalent to 3^5 / 3^8, since 1/9 is not equal to 3^-3.
C. (1/3)^8: This is equivalent to 1/3^8 by applying the exponent to the numerator and denominator. Then we can simplify 1/3^8 to 1/6561 by multiplying 3 by itself 8 times. This is not equivalent to 3^5 / 3^8, since 1/6561 is not equal to 3^-3.
D. 1/9: This is equivalent to (1/3)^2 by writing it as a power of a fraction. Then we can apply the same steps as in option B and get back to 1/9. This is not equivalent to 3^5 / 3^8, since 1/9 is not equal to 3^-3.
E. 3^14: This is not equivalent to 3^5 / 3^8, since it has a positive exponent and does not have a fraction. We cannot simplify it further without changing its value.
F. 3^2: This is not equivalent to 3^5 / 3^8, since it has a positive exponent and does not have a fraction.
Therefore, by the given fraction the answer will be 3^2.

An arc of a circle has a length of 4pi units. If the circle it comes from has a radius of 12 units, what is the measure of the central angle in radians associated with this arc?
NO LINKS PLEASE
If we start with a circle with a marked radius line, and turn the circle a bit, the area marked off looks something like a wedge of pie or a slice of pizza; this is called a "sector" of the circle, and the sector looks like the green portion of this picture:
circle with central angle "θ" and radius "r" marked, delineating the sector, which is shaded a light green
The angle marked off by the original and final locations of the radius line (that is, the angle at the center of the pie / pizza) is the "subtended" angle of the sector. This angle can also be referred to as the "central" angle of the sector. In the picture above, the central angle is labelled as "θ" (which is pronounced as "THAY-tuh").
