Answer:
d = 3 c= 1/4
Step-by-step explanation:
Eq. 1) -4c + 5d = 14
Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )
subtract Eq. 1 and Eq. 2
2d=6
d=3
plug 3 in for d in Eq. 1
-4c + 5(3) = 14
-4c + 15 = 14
-4c = -1
c = 1/4
Answer:
Therefore the correct option is a.) The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
Step-by-step explanation:
i) Let p = 0.47
ii) therefore q = 1 - 0.47 = 0.53
iii) sample size, n =25
iii) standard deviation = 
Therefore the correct option is
a.) The standard deviation is 0.0998. The 10% condition is met because it
is very likely there are more than 250 catfish in the river.
Future amount after 6 years will be: $10720.76
Step-by-step explanation:
Principal = $8000
Interest= 5% compounded annually
Time = 6 years
We need to find A (future amount)
The formula used is:

A= Future amount
P= Principal amount
r= interest rate
n= no of times interest is applied
t= time
Putting values and finding A
P=8000. r=0.05, n=1, t=6

So, Future amount after 6 years will be: $10720.76
