Answer:
3pf² - 21p²f + 6pf - 42p²
= 3pf² + 6pf - 21p²f - 42p²
= 3pf(f +2) - 21p²(f + 2)
= (3pf - 21p²)(f +0 2)
Answer: (3pf - 21p²)(f + 2)
Step-by-step explanation:
You basically just split it right down the middle. if the cost of something is lets say $75.58, then you would divide 75.58 by 2, which is $37.79
hope it helps!!
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.
