Kathi had a rope of 63.45 m. She cut the rope into two pieces. If the length of one piece was 23.59 m, what was the length of the other piece?
Answer:length of the other piece=39.86m
Step-by-step explanation:
Total length of rope =63.45 m
length of one piece = 23.59 m
Since the rope was cut into two pieces, we subtract the length of known first piece from the total length
length of the other piece = 63.45 m-23.59 m=39.86m

Isabel has ridden 16 miles of a bike course. The course is 80 miles long. What percentage of the course has Isabel ridden so far?
Answer:
20%
Step-by-step explanation:
Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%
Isabel has completed 20 percent of the race of 80 miles.
What is the percentage?A percentage is a quantity or ratio that, in mathematics, represents a portion of one hundred. It is one method for illustrating a relationship between two integers that has no dimensions.
Given, Isabel has ridden 16 miles of a bike course. The course is 80 miles long. From the general formula of percentage:
For the percentage, we have to divide the value by the total value and then multiply the result by 100.
percentage of the course has Isabel ridden so far = (16/80) * 100
percentage of the course has Isabel ridden so far = 1/5*100
percentage of the course has Isabel ridden so far = 20%
Therefore, Isabel has ridden 20 percent of the course which is 80 miles.

Pablo grew a plant for school and recorded the growth of the plant
each week. He wrote ordered pairs to organize his data: (1, 5), (2, 8),
(3, 8), (4, 11), (5, 15).
Is this relation a function? Explain.
Answer:
Yes. the relation is a function
Step-by-step explanation:
Here, we want to check if the relation is a function
if a relation is a function, then every x-values (input values) will have one y-value
No two output values (y values) will have a single x value
Looking at the pairs;
It is a function
Although two x values have same y value; 2 and 3 to 8; no two y values have same x value
Hence, the ordered pairs is a function
The outcome of the first event does affect the outcome of the second, so that the probability is changed
Answer:
Dependent Events
Step-by-step explanation:
Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.
If the first ball is chosen the probability will 1/3 leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3. In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.
In this the events are called dependent events.
Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.
