The relative minimum point in the graph is (-6, 2)
<h3>How to determine the relative minimum?</h3>
To do this, we simply locate a point that at a lower level, when compared to its neighboring points
Using the above highlight, there is only one relative minimum point in the graph
And the point is located at (-6,2)
Hence, the relative minimum point in the graph is (-6, 2)

Answer:
50 questions
Step-by-step explanation:
Given the following question:
92% of 50
To find the answer we have to use the formula to calculate percentage.
Which means in total there was "50 questions" on the test.
Hope this helps.
Answer:
Step-by-step explanation:
From the information given,
Mean, μ = (10.31 + 17.22 + 26.62 + 22.84)/4 = 19.2475
Standard deviation, σ = √summation(x - mean)/n
Summation(x - mean) = (10.31 - 19.2475)^2+ (17.22 - 19.2475)^2 + (26.62 - 19.2475)^2 + (22.84 - 19.2475)^2 = 151.249475
σ = √(151.249475/4)
σ = 6.15
number of sample, n = 4
The z score for 98% confidence interval is 2.33
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
19.2475 ± 2.33 × 6.15/√4
= 19.2475 ± 2.33 × 3.075
= 19.2475 ± 7.16
The lower end of the confidence interval is 19.2475 - 7.16 = 12.09
The upper end of the confidence interval is 19.2475 + 7.16 = 26.41
