Answer:
The correct option is b) 4.71
Step-by-step explanation:
Consider the provided information.
Test statistic for proportion: 
It is given that the claim is that the proportion of accidental deaths of the elderly attributable to residential falls is more than 0.10, and the sample statistics include n=800 deaths of the elderly with 15 percent of them attribute to residential falls.
Therefore, 
, p = 0.1, q = 1-0.1 = 0.9 and n = 800.
Substitute the respective values in the above formula.
Hence, the correct option is b) 4.71

Step-by-step explanation:
Answer:
3 2/3
Step-by-step explanation:
The x value is the same for both points. So we're only trying to figure out the difference in the y values. One y value is three steps down from zero and one y value is 2/3 of a step up from zero. So the total vertical distance between the two points is 3 and 2/3.
let's notice those tickmarks, meaning those sides are equal, meaning the line inside the triangle is really the midsegment of the triangle, that cuts both sides in equal sides, and it has a parallel side of 16.
Check the picture below.
