Answer:
0
Step-by-step explanation:
-10 + 10
-10 and 10 are additive inverses, so when we add them, it is equal to zero
-10 + 10 = 0
Answer:
45
Step-by-step explanation:
-5x^2 - y^3 when x = -4 and x = -5
~Substitute
-5(-4)^2 - (-5)^3
~Simplify
-5(16) - (-125)
-80 + 125
45
Best of Luck!
You can get the number by dividing 19.2 by 0.40
The number is 19.2/0.40 = 48
Answer:
6.68% of students from this school earn scores that satisfy the admission requirement
Step-by-step explanation:
Problems of normally distributed samples are 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:

The local college includes a minimum score of 1954 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement
This is 1 subtracted by the pvalue of Z when X = 1954. So



has a pvalue of 0.9332
1 - 0.9332 = 0.0668
