Answer:
The more fish Carl tests, the more likely he is to find a 30% parasite incidence rate.
Step-by-step explanation:
Given that fish inhabiting the river in the town of Glenmeadow have a 30% rate of parasite incidence
Carl is a fisherman who wants to verify the parasite infection rate of Glenmeadow's fish.
Sample size of 1000 i.e. 1000 fish is caught.
The interpretation of the given statement is
The more fish Carl tests, the more likely he is to find a 30% parasite incidence rate.
is the interpretation of population proportion rate for catching fish.
Answer: the investment would be
$110.45
Step-by-step explanation:
Initial amount deposited into the account is $100 This means that the principal is
P = 100
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 4
The rate at which the principal was compounded is 5%. So
r = 5/100 = 0.05
It was compounded for 2 years. So
t = 2
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 100 (1+0.05/4)^4×2
A = 100 (1.0125)^8
A = $110.45
Answer:
(- 2, - 10 )
Step-by-step explanation:
Given the 2 equations
y = x - 8 → (1)
y = 5x → (2)
Substitute y = 5x into (1)
5x = x - 8 ( subtract x from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
Substitute x = - 2 into either of the 2 equations for y
Substituting into (1)
y = - 2 - 8 = - 10
solution is (- 2, - 10 )
Answer:
x=144
Step-by-step explanation:
We got x and x/4 right
If you put x on the same line as x/4, you gon see that x+x/4=180
Then, just do your algebra and get x=144
