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.
Answer:
So we divide 128 into 14 which is 9.14285714286 but that eo be impossible so next we round to the nearest number which is now 9 now we multiply 9 by 14 and that gives us 126
I believe this is the answer
90
Plug in 7 for x and solve.
The Answer: 0.35 cents
2.10 divided by 6= 0.35
Answer:
x = 120
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then
x = 70 + 50 = 120
