0.843 that should be rounded from the nearest 100th
Answer:
a = x and b = 4
Step-by-step explanation:
x^3 - 64 = (x - 4)(x^2 + 4x + 16)
so
a = x and b = 4
Answer:
The numerical limits for a D grade is between 57 and 64.
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:

D: Scores below the top 80% and above the bottom 7%
Between the 7th and the 100 - 80 = 20th percentile.
7th percentile:
X when Z has a pvalue of 0.07. So X when Z = -1.475.




So 57
20th percentile:
X when Z has a pvalue of 0.2. So X when Z = -0.84.




So 64
The numerical limits for a D grade is between 57 and 64.
Answer:Dy/DX=52
Step-by-step explanation:
dy/DX=d/DX(52x)+d/DX(1)
Dy/DX=52
