Answer:
<em>72 passenger planes</em>
Step-by-step explanation:
ratio passenger to cargo = 8 to 5 = 8/5
Let p = number of passenger planes.
The ratio of passenger to cargo planes that actually landed is p/45.
The ratio in general is 8/5, so 8/5 must equal p/45.
p/45 = 8/5
5p = 45 * 8
p = 9 * 8
p = 72
Answer:
246
Step-by-step explanation:
In the statment is defined our Values.
First que have a 95% Confidence interval
That is exactly in a Standar normal distribution table equal to Z Score = 1.96
The proportion 
= 0.20
And we can and Margin Error (ME) equal to 0.05
Using the formula for the Sample Size (N) through Proportion we have,
or 246
Answer:
- 7 / 4
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
Slope = (1 - -6) / (-5 - -1)
Slope = - 7 / 4
Answer:
Z = 6
Step-by-step explanation:
To solve this equation, we can do the opposite of -6/3 to isolate Z and get our answer. The opposite of -6/3 is +6/3, so we add 6/3 to both sides.
Z - 6/3 = 4
+6/3 +6/3
Z = 4 + 6/3
Z = 4 + 2
Z = 6
