Answer:
65 dinners are expected to show up
The standard deviation of the distribution is 3.13
Step-by-step explanation:
Given
Proportion = 15%
Population = 77
Required
Expected Number that'll show up
Standard Deviation
<em>If 15% won't show up; then</em>
<em>100% - 15% = 85% will show up</em>
Expected Number, E(x) of Dinner is calculated as thus;
Where 
(calculated above)
and 
Convert p to decimal
So;
<em>65 dinners are expected to show up</em>
Calculating Standard Deviation, SD
Standard Deviation is calculated as;
Substitute 0.85 for p and 77 for n
(Approximated)
<em>The standard deviation of the distribution is 3.13</em>
Hey there! I'm happy to help!
So we want to see which of these have the greatest value. Since these are all negative numbers, we want the one that is closest to zero.
So, we know that -1000 is going to furthest from 0. -10 will be further than -8 since it is a larger negative number, so it will be more negative than -8.
-1/2 is just barely negative, so it is going to be closer to -0 than -8, so the correct answer is C. -1/2.
Have a wonderful day and keep on learning! :D
Answer:
Dale would reach his goal with an annual interest rate of 6.18%.
Step-by-step explanation:
For compounding continuously, recall the following equation:
A = final amount ($4200)
P = principal amount ($2000)
r = rate (unknown)
t = time (12 years).
You'll have to use natural logs for these types of questions. Remember that ln (e) = 1.
