2. The roots of a polynomial are where the graph crosses the x-axis. Find each of the following polynomials' roots and find the
factorization of the polynomial graphed.
Step 1: Identify the roots for each polynomial. You may assume that each graph crosses the axes at a tick mark. (4 points; 2 points each)

Answer:
27% of the possible Z values are greater than 0.613
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.
In this question, we have that:
27% of the possible Z values are greater than
The 100 - 27 = 73rd percentile, which is X when Z has a pvalue of 0.73. So X when the z-score is 0.613.
27% of the possible Z values are greater than 0.613
