For this problem you can do it one of two ways. The first way would be simply take the square root because the area of a square is one side squared. The other way using the same rule would be to go up from a reasonable number and square it, if that is not the number you are looking for add 1 to the original number and square it again. if you cannot square and square root in your head, you should be allowed to use a calculator to get the answer or 17 as the length of a side.
Answer: 0.065
Step-by-step explanation:
Given : Sample size : n= 320
The sample proportion of people who rent their home :
Significance level :
Then , Critical value :
The formula to find the margin of error : -
Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065
The answer is D The value of X can be any real number greater than or equal to 0 but the value of Y must be an interger greater than or equal to 0.

Answer:
a) θ = 15° b) θ = 15°, 165°
Step-by-step explanation:
a) Given the equation 2 sin(2θ) = 1
sin(2θ) = 1/2
(2θ) = arcsin(1/2)
2θ = 30°
θ = 15°
b) To find all the solutions between 0 and 2π, we will make reference to the quadrant.
Sinθ is positive in the first and second quadrant.
In the first quadrant, θ = 15°
In the second quadrant, θ = 180°-15°
= 165°
The solutions between 0 and 2π are 15° and 165°
