Answer:
230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)
Step-by-step explanation:
First I will convert the minutes into seconds to make this a little easier.
1:01.71 would just be 61.71 seconds
400/61.71 is her speed for the first race. (speed is distance/time)
That is approximately 6.5 meters per second
time is distance/speed
1500/6.5= 230.769...
I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.
Seventeen-thousand and one hundred 6 thousandths written in standard form would be 17,000.106
Hope this helped =)
Answer: A difference of about 7.32%.
Step-by-step explanation: To find the percentage of chance, you would need to plug the numbers into this equation: |V1−V2| / ( (V1+V2)/2)×100=
Here is the answer
So as the triangle is congruent their sides angle all are same so the remaining angle in figure 2 (angle P) is 70

Answer:
23.89% probability that a randomly selected firm will earn more than Arc did last year
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If incomes for this industry are distributed normally, what is the probability that a randomly selected firm will earn more than Arc did last year
This is 1 subtracted by the pvalue of Z when X = 85. So
has a pvalue of 0.7611
1 - 0.7611 = 0.2389
23.89% probability that a randomly selected firm will earn more than Arc did last year
