Answer:
0.92 and 1.25 respectively
Step-by-step explanation:
0.92 and 1.25 respectively
first the mean of each value which is 9.7 and 9.8 respectively
standard deviation = square root of the mean deviation of each value
then deduct the mean from each element
and square each value and add them together. not you should square each deviation value before you add them
at last divide the result by the number of frequency and find it's square root
U count how many students were walking then multiply it by half itself
absolute value is 8 because the absolute value of a negative is positive and the absolute value of positive stays positive
After a year the
population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after
1 year it will be: <span>
3800 x 0.986
after 2 years it will be:
3800 x 0.986 x 0.986...
after 3 years: 3800 x (0.986)^3
<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 =
which is 3591.62724 or 3592</span></span>
