Answer: The interval is 0.9 ± 0.0259 and margin of error is 0.0259

Step-by-step explanation: Confidence interval for a proportion in one sample is the estimate of the proportion of a population. It is calculated following the next steps:

1) Find the proportion $p=\frac{x}{n}$ , in which x is the number of people with the desired condition. In our case, p=0.9;

2) Calculate margin of error, i.e.:

$z\sqrt{\frac{p(1-p)}{n}}$

z is z-score, which for a 95% confidence, equals 1.96;

Substituting with the data given:

$1.96(\sqrt{\frac{0.9(1-0.9)}{514}})$ = 0.0259

3) Write: p ± $z\sqrt{\frac{p(1-p)}{n}}$

In our case, the interval will be 0.9 ± 0.0259.

Margin of error is the random sampling error in the results of a survey, i.e.,it shows you how far your result will be from the real value. For the Harris poll, margin of error is 0.0259

Maria leaves her house and walks north for 6 blocks. She then turns and walks directly east for 8 more blocks

Shtirlitz [24]

Answer:

36+64=100 100 to the square root is 10

Step-by-step explanation:

I'm not giving a diagram just draw a triangle and make the base of it 8 and the length of it 6 but the diagonal part 10

It's the pythagorean theorum. a^2 + b^2 = c^2

^2= to the 2nd power. or squared.

In this case it really doesnt matter which one you label for this part of math.

so 8^2 + 6^2 = C^2 where C is the shortest distance between the houses.

and 8 and 6 were the lengths given.

64+36=100

100's square root is 10 because 10^2 is 100 or 10*10 is 100. If you dont know what squaring is.

Its multiplying something by that something once so 1 squared is 1 because its 1*1 you are multiplying it once 2 squared or 2^2 is 4 because 2*2 is 4 3 squared or 3^2 is 9 because 3*3 is 9. 4 squared is 16 because 4*4 is 16. and if you did 2 to the power of 3 of 2 cubed it would be 8 because 2*2*2 is 8.
