1 answer:
Answer:
This is a 5th degree single variable polynomial.
Step-by-step explanation:
We have to classify the given polynomial by degree.
This is a 5th-degree single variable polynomial. (Answer)
Note :
(i) ax + b is the general form of a single degree i.e. linear single variable polynomial.
(ii) cx² + dx + e is the general form of two degrees i.e. quadratic single variable polynomial.
(iii) px³ + qx² + rx + s is the general form of three degrees i.e. cubic single variable polynomial.
In this way, the degree of a polynomial increases with the maximum power of the variable.

Answer:
The width of the scale model is 33 inches.
Step-by-step explanation:
This question is solved making a relation with the scale model.
In the scale, 3 inches are worth 11 real feet.
The actual width of the building is 121 feet, so we find it's scale by a rule of three.
3 inches - 11 feet
x inches - 121 feet
Simplifying by 3, both sides
The width of the scale model is 33 inches.

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 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.
Mean of $8.52 with a standard deviation of $2.38
This means that
The stock price beyond which 0.05 of the distribution fall is
This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.
The stock price beyond which 0.05 of the distribution fall is $12.44.
