In order to factor, we must pull out factors common to each term. In this case, each term has factors of 2 and y:
4ay = 2 * 2 * a * y
2y = 2 * y
So, we'll pull out the 2y:
To check, distribute the 2y back through the terms in parentheses to ensure you end up with the original expression 4ay - 2y.
4ay = 2 * 2 * a * y
2y = 2 * y
So, we'll pull out the 2y:
To check, distribute the 2y back through the terms in parentheses to ensure you end up with the original expression 4ay - 2y.
Answer:
0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean of $0.35 and a standard deviation of $0.33.
This means that .
What is the probability that a randomly selected stock will close up $0.75 or more?
This is 1 subtracted by the p-value of Z when X = 0.75. So
has a p-value of 0.8869.
1 - 0.8869 = 0.1131
0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.
