The slope is the value in the term with "x". That is 2/9x has "x".
In this case, the slope will be 2/9
I used Desmos Graphing Calculator. Helps so much!
Hope this helps!
Answer:
Due to the higher z-score, Jane did better in class.
Step-by-step explanation:
Z-score:
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:
Whoever's grade had the better z-score did better in class.
Mary's:
Mean of 85, standard deviation of 5, grade of 88. This means that . So
Jane's
Mean of 80, standard deviation of 10, grade of 88. This means that . So
Due to the higher z-score, Jane did better in class.
By definition the rate of change of a function is given by:
Or equivalently:
Substituting the values given in the problem we have:
Rewriting we have:
Answer:
the rate of change of the ramp is:
