6.974 rounded to the nearest tenth is 7.0, because 7 is more than 5, and since 9's there, we make that 6 to a 7.
Answer:
A student must obtain a grade of at least 84.2 in order to get an A.
Step-by-step explanation:
Problems of normally distributed samples 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.
In this problem, we have that:
If only the best 14 % of the students in the class will receive an A, what grade must a student obtain in order to get an A?
This is the value of X when Z is in the (100-14) = 86th percentile.
So it is the value of X when , and higher values of X. So
A student must obtain a grade of at least 84.2 in order to get an A.
Answer:
AD = 11 units
Step-by-step explanation:
d = √(-6+6)²+(5+6)²
d = √11²
d = 11
