<u>Answer</u>
First diagram shows 1 and 2 vertical angles
<u>Explanation</u>
From the all four diagrams,we get the diagram first shows the vertically opposite angles.
angle 1 and angle 2 are vertically opposite angles
vertically opposite angles are equal in measurements. when two lines are intersect each other form four angles, out of this four angles two pairs of vertically opposite angles are there.
All other figures angle 1 and 2 shows adjacent angles.
Answer:
Step-by-step explanation:
Given that two well-known aviation training schools are being compared using random samples of their graduates
Fly more academy 70 of 140
Blue Yonder 104 of 260
Combined pass = (70+104) out of (140+260)
a) Pooled proportion=
b) H0: p1 = p2
Ha: p1 ≠p2
(two tailed test)
p difference= 
std error for difference (using pooled proportion) = 
Test statistic = p difff/std error = 4.034
c) Critical value for 0.05 is 1.96
d) p value is < 0.005
Since p < 0.05 our significant level we reject H0
There is significant difference between the two proportions.

Step-by-step explanation:
Answer:
The least value plotted on the line plot is 18.0
The greatest value plotted on the line plot is 22.0
The height of inches occurs the most often is 19.5 with 3 times
Step-by-step explanation:
A line plot is a graph that shows frequency (the number of times the data value occur) of data along a number line.
The line plot has dots plotted on it over each value of the number line.
Answer:
The main reason it was important to study this group was:
1) If Whitehead had found that many people had drunk water from the Broad Street pump and not caught cholera, that would have been evidence against Snow's hypothesis.
Step-by-step explanation:
But Dr. John Snow was able to convince many councillors who ensured that the pump handle was removed from the Broad Street pump. Within a few days of this removal, the cholera epidemic ended. This step proved that Dr. Snow was right from the beginning. The pump handle was the means that the cholera epidemic was being spread from one person to another within Broad Street area, since many usually fetch water from the pump.
