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.
Intersecting lines are lines that meet at some point while perpendicular lines are intersecting lines that makes a right angle at the point of intersection.
Two line can either be intersecting or perpendicular. It is not possible to have two line that is neither intersecting or parallel.
Answer:
3/16
Step-by-step explanation:
since the question has "and" we will be multiplying two unrelated probabilities
P(gray on 1) = 1/4
P(blue on 2) = 3/4
the second probability is not affected since we are not taking away the first space after we land on it
1/4 * 3/4 = 3/16

Answer:
1. 72
2. 60
3. 35
4. 32
Step-by-step explanation:
1. 6 x 4 x 3= 72
2. 5 x 3 x 4= 60
3. 5 x 2 x 2= 20
5 x 3 x 1= 15
20 + 15= 35
4. 5 x 3= 15
2 x 2=4
4 x 8= 32
