Answer:
73.6
61.824
.2776
2.3
1.342
.4129
*note* I had trouble reading the standard deviation of the second part, so if it's not 3 then leave a comment and i will fix it*
Step-by-step explanation:
1.)
the mean would be something like 460*.16= 73.6
The variance should be 460*.16(1-.16)= 61.824 which means the standard deviation is √61.824= 7.863
for p to be less than .15 it would have to be less than .15*460= 69
(69-73.6)/7.863= -.59 which has a probability of .2776
2.)
the mean is 2.3
I am not sure if the standard deviation is 3 or .3 (picture is kind of blurry)
I am thinking that it's three which would mean that the standard deviation would be √(3²*(1/5))= 1.342
(2-2.3)/1.342= -.22 = .4129
What's the question she got the answer wrong to?

Answer:
If interest is calculated yearly, it will take Tim approximately 6 years
Step-by-step explanation:
For interest compounded continuously we use this formula
A = pe^rt
Where A = Amount in future ($5,300)
P = Principal amount ($5,000)
r = interest rate (1% or 0.01)
t = time
Now we put the values
5300 = 5000e(0.01)t
1.06 = Ve(0.01)t
㏑1.06 = 0.01t
t = ㏑(2) ÷ 0.01
t = 5.82 years rounded to 6 years
If interest is calculated yearly (simple interest)
n = ( 1.06-1 ) / 0.01 = 6 years.
If interest is calculated yearly, it will take Tim approximately 6 years.
