Answer:
<h2>See below</h2>
Step-by-step explanation:
Theoretical probability is the actual chance of something happening based on raw numbers.
For example: The theoretical probability of tails on a coin flip is 1/2 or 50%. If you flipped a coin, you would expect 50% to be heads, 50% to be tails.
However, since this almost never happens, experimental probability is used to describe the actual results.
For example: If you flip the coin 50 times and 23 are tails, 27 are heads, then the experimental probability is 46% for tails and 54% for heads.
I'm always happy to help :)
Probability helps us to know the chances of an event occurring. The probability that a randomly selected student is a junior is 0.35.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
The probability that a randomly selected student is a junior will be,
P(Junior) = [(Number of Juniors)\(Number of total students)]
P(Junior) = 35/100 = 0.35
Hence, The probability that a randomly selected student is a junior is 0.35.

The inequality that describes the calories burned is 7x + 9y ≥ 441
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441

Answer:
8 1/2
Step-by-step explanation:
16+25=41+25=66+25=91+25=116+25=131+25=156+25=181+25=201+25=226
so it takes 8 and a half hours
9)=A These two are indications of a chemical change. (I am positive it is A)
10)=A It is not D and the others don't seem as right so I hope this helps.
