Answer:
3/4
Step-by-step explanation:
Average change is change in y / change in x
(y2-y1)-(x2-x1)
(3-0)/(-3-(-7))
3/4
In (-7,0)
-7 is x1, 0 is y1
In (-3,3)
-3 is x2 and 3 is y2
The answer is 2-5i. Hope this helps
Answer:
1-342.1
2-557.2
3-285.2
4-201.6
5-33.1
6-6
7-356.4
8-1000
Step-by-step explanation:
2,380
23 hundred = 2,300
7 tens = 70
10 ones = 10
2,300 + 70 + 10 = 2,380
Answer:
0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24
Step-by-step explanation:
When the distribution is normal, we use 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.
The price is approximately normally distributed with a mean of 20 and a standard deviation of 2.
This means that
What is the probability that in a year the shares will be selling between $21 and $24
This is the pvalue of Z when X = 24 subtracted by the pvalue of Z when X = 21. So
X = 24:
has a pvalue of 0.9772
X = 21:
has a pvalue of 0.6915
0.9772 - 0.6915 = 0.2857
0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24
