Answer:
20 m
Step-by-step explanation:
Data provided in the question
Completed desired distance by Arman, Babken, and Cecilla = 100m
At the time of crossing the finish line by Arman, Babken was 10m behind him
And, Cecilla was 10 m behind him when the Babken crossed the finish line
Based on the above information, the distance between Cecilla behind Arman at the time of finish line crossed is
= 10 m + 10 m
= 20 m

Answer:
B-12
Step-by-step explanation:
Since 24÷12=2 you have to do 6×2 to find the ? and 6×2=12
Answer:
The correlation coefficient is close to -1. There is a strong negative correlation between the amount of time spent working out and the amount of weight lost.
Step-by-step explanation:
I did it on USATestprep. -0.9547 is close to -1. This indicates a strong negative correlation. When the workout time increases, Jason's weight decreases.
<span>Use the log properties: LogA+logB=log(A*B) and log(A/B)=logA-logB.
ALso NlogA=log(A^N).
So 2log4=log4^2=log 16.
2logx=logx^2. Then we have log16-log3+logx^2-4=0.
Bring the 4 to the other side:
log16-log3+logx^2=4 Combine using the properties into one log:
log(16/3)*x^2=4.
With log, the understood base is 10. log _(10) [ (16/3)*(x^2]=4 where_10 means base 10.
We know log_b M=N means b^N=M by the definition of log. We use that here and change log into an exponential equation:
10^4=(16/3)x^2
10000 *(3/16)=x^2
Taking the square root we have + or- 43.30127.
We only want the positive solution since we can only take the log of positive numbers.
Our answer rounded is 43.3013.</span>
