Answer:
240 miles
Step-by-step explanation:
To solve this we need to write an equation. For this problem let <u>d be the distance traveled</u>. We know that the new train (being much more modern than poor old Thomas who is long retired) can go 20% further. To show this we will take 20% of 200 and then add that to the original distance.
Our equation would look something like this:
d=200+(20%·200)
[one more little note: to find percentage take your percent and convert it into a decimal 20%=0.2)
d=200+(0.2·200)
d=200+40
<u>d=240</u>
The answer is $30 she would save 30 dollars in a 24 week period
Answer:
Step-by-step explanation:
hello :
f(t) = 1/t - 1
calculate : t
f(t)+1 = 1/t so : t = 1/(f(t)+1)
f^ -1 (t)= 1/(t+1)

Answer:
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%
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:
What is the probability an individual large-cap domestic stock fund had a three-year return of at least 19%
This is 1 subtracted by the pvalue of Z when X = 0.19. So
has a pvalue of 0.8519
1 - 0.8519 = 0.1481
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%
