Answer:
0.7823 = 78.23% probability that the response time is between 3 and 9 minutes.
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.
Normal distribution with a mean of 7.2 minutes and a standard deviation of 2.1 minutes.
This means that
Probability that the response time is between 3 and 9 minutes.
This is the pvalue of Z when X = 9 subtracted by the pvalue of Z when X = 3. So
X = 9
has a pvalue of 0.8051
X = 3
has a pvalue of 0.0228
0.8051 - 0.0228 = 0.7823
0.7823 = 78.23% probability that the response time is between 3 and 9 minutes.
Answer:
The polynomial equation that cannot be solved using the quadratic formula: Option2:
Step-by-step explanation:
First of all we have to learn what a quadratic polynomial is.
A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.
The quadratic equation is of the form:
From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.
Hence,
The polynomial equation that cannot be solved using the quadratic formula: Option2:
