Answer:
AB
Step-by-step explanation:
A ray has one endpoint and the rest is a line, so AB would be the only answer that would make sense in this situation (because it's starting from A and B is a point on the ray).
Answer:
(b) 4,445
Step-by-step explanation:
If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?
Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)
So n=(Z/E)^2*p*(1-p)
=(1.96/0.015)^2*0.5*0.5
=4268.444
Take n=4269
Answer:(b) 4,445
Answer:
It will increase by 0.2%.
Step-by-step explanation:
In this problem we need to solve for the monthly interest first.
We use the formula:
Now that we have the formula we now define our variables.
i = 20.87% or 0.2087
n = 12
or 23%
Now we have to find the daily interest rate.
or 23.20%
23.20% - 23% = 0.20% increase.
You are asked to find the error. The error is that 4,100,000 is the answer to 4.1×10^6, not 4.1×10^-6. The correct answer to 4.1×10^-6 is 1/4,100,000.
U is between N and S.
The order of the letters does not matter, thus:
NU = 1 and US = 2 so NS = 3.
This is only possible if NU + US = NS
Proving U is between N and S.
