Answer:
Input
Step-by-step explanation:
Y is the output.
At 95% confidence interval, the z score is 1.96. Using the
formula:
Confidence Interval = x ± z s / sqrt (n)
where x is the average time served, s is standard deviation
and n is number of samples
Confidence interval = 7.5 ± (1.96 * 3) / sqrt (400)
Confidence interval = 7.5 ± 0.294
<span>Confidence interval = 7.206 to 7.794</span>
The conjecture or hypothesis given based on the attached graph is that there has been a general increase in the total loss of the Greenland Ice Sheet since 2007. However, since 2013, the rate at which the total loss increased began to decline.
<h3>What is a conjecture in math?</h3>
In mathematics, a hypothesis or a conjecture is a speculative conclusion or assertion that is stated without evidence.
<h3>How do you write a Conjecture ?</h3>
You must discover a trend or make some type of remark. For example, you may have observed that the list is increasing by twos.
You draw a conclusion based on the pattern you saw, just as you did when you determined that 18 would be the following number.

1 over 5a to the 2nd power
X = -b/2a
x = -8/4
x = -2
Plug -2 in for x and solve for y
y = 2(-2)^2 + 8(-2) -3
y = 8 -16 -3
y = -11
Vertex (-2, -11)
