Answer:
The first quartile of the IQ scores of adults is 82.26.
Step-by-step explanation:
The first quartile is the value that is greater than 25% of the observations and less than 75% of the observation.
The formula to compute the first quartile (Q₁) of a Normal distribution is:
The mean and standard deviation of the IQ scores of adults are:
Compute the first quartile value as follows:
Thus, the first quartile of the IQ scores of adults is 82.26.
<span>Turn the percent to a decimal by moving the decimal point over 2 places to the left. then multiply. so, 1425 * 375</span> = 53.44
Answer:
9.407x10-11
Step-by-step explanation:
8.18(9.407x(10)−11)10−6(1.15(9.407x(10)−11)10−5)
8.18(9.407x(10)−11)10−6(1.15(9.407x(10)−11)10−5)
If there was 31 dogwood trees already there and after there was a total of 96 dogwood trees therefore all you would have to do is subtract (96-31) you would get 65 so the answer is 65
