<span>Depletion of the ozone layer has consequences on humans, animals and plants. This typically results from higher UV levels reaching us on earth.
Research confirms that high levels of UV Rays cause non-melanoma skin
cancer. Additionally, it plays a major role in malignant melanoma
development.</span>
I would write to him because I’d like to know why he had left.
where are the answers to choose from? if we have to pick the statement we need to know which answers we can choose
Answer:
1
Explanation:
(x-2)^2 = x equals 2 ( double roots)
(y-3)^2 = y equals 3 (double roots)
(z+4)^2 = -4 (double roots)
2 + 3 -4 =1
What the sample suggests is that; the mean body temperature couldvery possibly bevery possibly be 98.6 °F.
<h3>What is the Confidence Interval?</h3>
For a 99% Confidence Interval and DF = 103 - 1 = 102, the value of z = 2.33.
The formula for confidence interval is;
CI = x⁻ ± z(σ/√n))
We are given;
Sample mean; x⁻ = 98.9
standard deviation; σ = 0.67
sample size; n = 103
Thus the confidence Interval is;
CI = [98.9 - 2.33(0.67/√103)], [98.9 + 2.33(0.67/√103)]
CI = (98.9 - 0.154, 98.5 + 0.154)
CI = (98.36, 98.64)
Thus, 98.6 is contained within the 99% CI,and so we can conclude that the the mean body temperature could very possibly bevery possibly be 98.6 °F.
