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.
3(d) and 3 (g)
d represents the price. so you multiply 3 by however much the has cost.
g represents the gallons and 3 represents the cost and again you multiply
we know that
Two angles are supplementary if their sum is equal to
degrees
in this problem we have


so
therefore
<u>the answer is</u>
The two angles are supplementary
