Answer:
x= 16.6
Step-by-step explanation:
The circle is unnecessary. You can just use Pythag Theorem
so
9^2+14^2= c^2
81 + 196 = 277
square root 277
16.64
round to the nearest tenth...
16.6
Answer:
The margin of error for the survey is 0.016
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1024
Sample proportion:

We have to find the margin of error associated with a 90% Confidence interval.
Formula for margin of error:


Putting the values, we get:

Thus, the margin of error for the survey is 0.016
Cosine is adjacent/hypotenuse
The adjacent side to angle F is 60, and the hypotenuse is 61
Therfore, C) 60/61 would be the correct choice
