13 times 4 is 52
9 times 4 is 36 plus the 20 it takes for reservation
So the maximum amount would be 4
We have that since the chords are equal, the arcs are equal too. Hence AB=RS. We also have that AB=AR+RB and RS=RB+BS. By equating these two, we have that AR=BS. Hence BS=55 degrees. Substituting back, since we know RB and BS, we get: RS=55+66=121 degrees
Answer:
About 16% percent of people should have IQ scores above 118.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 100
Standard deviation = 18
Using the empirical rule, about what percent of people should have IQ scores above 118?
118 = 100 + 18
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean, that is, between 82 and 118. The other 32% is more than 1 standard deviation from the mean. Since the normal distribution is symmetric, 16% are below 82 and 16% are above 118
So
About 16% percent of people should have IQ scores above 118.
