CD = 13
6x - 5 = 4x + 1, combine like terms to get
2x = 6, divide 6 by 2
x=3, plug it in...
CD= 4(3)+1, which is 12 + 1
CD = 13
Answer:
-5
Step-by-step explanation:
Given the functions
f(x) = 2x - 20
g(x) = x - 1
f(x)/g(x) = 2x - 20/x-1
f/g(x) = 2x - 20/x-1
Substituting x = -5 int the result
f/g(5) = 2(5) - 20/5-1
f/g(5) = 10 - 20/4
f/g(5) = -10/4
f/g(5) = -5
Hence the result is -5
We know that renting the car will cost $30, regardless of whether you drive it any where or not
So far
C = $30
On the end of this equation, we want to be able to add another value, that can vary depending on the quantity of M (number of miles)
The second value is $0.05 multiplied by how many miles are travelled
Also expressed as $0.05M
Finally, just fix the two parts together
C = $30 + $0.05M

Answer:
The probability that the sample proportion will be at least 3 percent more than the population proportion is 0.6157
Step-by-step explanation:
We need sample proportion between 0.75 - 0.03 = 0.72 and 0.75 +0.03 = 0.78. Here we have p = 0.75 and n= 158.
So z-score for sample proportion q = 0.72
z =
=
= -
= - 0.872
So z-score for sample proportion q = 0.78
z=
=
=
= 0.872
Therefore the probability that the sample proportion will be within 3 percent of the population proportion is
P( 0.72 < q < 0.78) = P ( -0.872 < z < 0.872)
= P( z < 0.872) - P( z < -0.872)
= 0.80785 - 0.19215
= 0.6157
