Answer:
Based on the data provided, Sergei can make the following predictions and set a benchmark for his performance:
Prediction 1: With consistent training and improvement over the summer, Sergei can predict that he will run the mile faster than 8:45 in his upcoming tryouts. This is based on the pattern of improvement he has shown from 9:30 (eighth grade) to 8:45 (freshman year) and his continued training.
Prediction 2: Sergei can aim to break the 8-minute mark for the mile based on the trend of his improvements. This is a reasonable goal given his past progress, and it aligns with his objective of making the varsity team where all runners need to run under 6:15.
Benchmark: The benchmark against which Sergei is measuring his performance is the time required to run a mile. He's tracking his progress in terms of how long it takes him to complete a mile, aiming to continuously improve and meet the varsity team's standard of running under 6:15 for the mile.
Answer:
c=2πr
c= 2*π*11
c=6.28*11
c=69.08
Answer:
Based on the data, the faster the vehicle travels, the less time it takes to reach the destination.
Step-by-step explanation:
The line of best fit is decreasing. This means that as x, the speed of the vehicle, increases, y, the time to reach the destination, decreases.
This means that the faster the vehicle travels, the less time it takes to reach the destination.
Answer:A.
The initial speed is 60 miles/hour, and his speed decreases by 15 miles/hour every hour.
Step-by-step explanation:since 15 is negative you will be decreasing.
Answer:
8/45
Step-by-step explanation:
(-2/-3)=2/3

(2/3)/(15/4)=2/3*4/15=8/45
So the answer is 8/45
Answer:
x > 7
Step-by-step explanation:
