Answer:
(1 / 2) * 1 3/5 * 2 7/9 = 2.22222222
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
First, you need to find the difference.
9/12 = .75
you then do:
32 x .75 = 24
ik this won't make much sense but i tried :/
it’s b 3/4 hours because when you split 1 1/2 in half it’s like if you split 150 into 75
Answer:
IQ scores of at least 130.81 are identified with the upper 2%.
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 100 and a standard deviation of 15.
This means that
What IQ score is identified with the upper 2%?
IQ scores of at least the 100 - 2 = 98th percentile, which is X when Z has a p-value of 0.98, so X when Z = 2.054.
IQ scores of at least 130.81 are identified with the upper 2%.
