Margin of error for a population proportion is given by = p^ + or - sqrt(p^(1 - p^)/n); where p^ = 10% = 0.1 and n = 300
margin of error = 0.1 + or - sqrt(0.1(1 - 0.1)/300) = 0.1 + or - sqrt(0.09/300) = 0.1 + or - 0.017 = 0.083 to 0.117 = 8.3% to 11.7% = 25 to 35 workers

Step-by-step explanation:
"container" of soap
Answer:
20
Step-by-step explanation:
The first step is to find out the similarity reason of the sides of the triangle, so we just divide the big side by the small side (12/4=3).
Now, for the similarity reason of the areas, we just square that number (3^2=9).
Then we just divide the area of the big triangle by 9, which is 180/9= 20.
Answer:
24% probability that both fund A and fund B will rise in price
Step-by-step explanation:
We have these following probabilities:
40% probability that fund A will rise in price.
If fund B rises in price, 60% probability that fund B does.
What is the probability that both fund A and fund B will rise in price
40% of A, and if A rises, 60% is B. Since the only outcome that interests us is both rising in price, we multiply these probabilities
24% probability that both fund A and fund B will rise in price
Answer:
w = 2.1
Step-by-step explanation:
5w + 9.2 = 19.7
5w + 9.2 - 9.2 = 19.7 - 9.2
5w = 10.5
5w / 5 = 10.5 / 5
w = 2.1
Here is the check:
5w + 9.2 = 19.7
5(2.1) + 9.2 = 19.7
10.5 + 9.2 = 19.7
19.7 = 19.7
