Use a calculator. 6 square root of 2 and 8 square root of 2. Times both of them and turns to 2304. Then 2304 square root of 2 again
If it is a straight line going across then the slope is 0.
Pablo has $4,200 to invest for college. Pablo's goal is to have $5,000 after 4 years. Question: Is this possible if he invests with a rate of return of 6%?We'll we are not sure with the answer unless we solve it. So let's start solving.=> 6% = 6% / 100% = 0.06Now, we have the value of 6% that will be multiplied with the amount to identify his annual interest rate:=> $4,200 * 0.06 = 252 dollars is his annual interest rateLet's multiply this for 4 years=> 252 dollars * 4 = 1008 dollarsThen, let's sum up:<span>=> $4,200 + 1008 dollars = 5 208 dollars.</span>
Answer:
The confidence interval for the difference of proportions of the population p2003-p2008 is
.
Step-by-step explanation:
In this question we have to construct a 90% confidence interval (CI) for a difference of proportions.
The proportion for 2003 is
.
The proportion for 2008 is
.
The difference in proportions is
.
The standard deviation of the difference of proportions can be estimated as:

For a 90% CI, the z-value is 1.64.
Then we can construct the CI as
