The graph is attached.
Answer:
(-2.2, 4) and (8.2, 4)
Step-by-step explanation:
In an ellipse, there is a minor radius and a major radius.
Let major radius be = a
Let minor radius be= b
From the graph, we are given:
Major radius, a = 6
Minor radius, b = 3
Now, let's find the distance from the center to the focus using the formula:
Substituting values, we have:
≈ 5.2
We can see from the graph that center coordinate is (3, 4). Therefore, the approximate locations of the foci of the ellipse would be:
(3-5.2, 4) and (3+5.2, 4)
= (-2.2, 4) and (8.2, 4)
793-61 is the correct answer
The ratio of false positives to false negatives is (d) 3.5
<h3>How to determine the ratio?</h3>
The table of values is given as
Activates. Does not activate Row Totals
Lightning in area 88% 2% 90%
No lightning in area 7% 3% 10%
Column Totals 95% 5% 100%
The false negative is when there is lighting and it does not activate
So, we have
False negative = 2%
The false positive is when there is no lighting and it activates
So, we have
False positive = 7%
When represented as ratio, we have
Ratio = 7% : 2%
So, we have
Ratio = 7 : 2
This gives
Ratio = 7/2
Evaluate
Ratio = 3.5
Hence, the ratio is (d) 3.5

Hey!
With the given information, we can form the equation y = 3x + 5, where y is the total and x is the number of miles.
IF the total amount was 29, we set y equal to 29.
29 = 3x + 5
subtract 5 from both sides
24 = 3x
divide both sides by 3
x = 8
Therefore he traveled 8 miles.
Answer:
Addition property of equality
Step-by-step explanation:
Given:
We need to find the missing reason in the proof.
Solution:
By solving the above equation we get;
⇒ Given:
Now by adding both side by 'x' we get;
⇒ Addition property of equality
Hence The missing reason in the proof was Addition Property of equality.
