Answer: The size of sample of 193 is needed.
Step-by-step explanation:
Since we have given that
Margin of error = 6%
At 90% confidence level, z = 1.645
Let p = 0.5
and q = 0.5
( because it is the most conservative estimation).
So, using formula, we get :

Hence, the size of sample of 193 is needed.
Answer:
there was no question, but if your asking how much there shrinking by the top one comes first and the 2nd shrinks down to twice the size.
Step-by-step explanation:
1. 958-236=722
2. 878-247=631
3. 998-346= 652
4. 967-323= 644
5. 998-353= 645
6.876-322= 554
7.948-526= 422
8.968-353=615
9. 798-363= 435
10. 978-735= 243
11. 693-572= 121
12. 867-432= 435
Answer:
7.0 mi
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

step 2
Find the measure of a
Applying the law of sines

substitute the given values

solve for a
