The answer to this question is II
Answer:
∘F=(9/5)∘C+32).
Explanation:
Coach Ferguson uses a thermometer to measure the temperature (in degrees Celsius) at 20 different locations in the school swimming pool. An analysis of the data yields a mean of
25∘C
and a standard deviation of
2∘C.
Find the mean and standard deviation of the temperature readings in degrees Fahrenheit (recall that
∘F=(9/5)∘C+32).
I would say c , personally but I’m not positive .. sorry
<h3>Answer: </h3>
about 0.296
<h3>Explanation:</h3>
The probability is found from ...
... C(12, 2)×(1/6)^2×(5/6)^10 ≈ 66×0.0044863 ≈ 0.29609
_____
C(n, k) = n!/(k!(n-k)!)
C(12, 2) = (12·11)/(2·1) = 66 . . . . the number of ways 7s can show up in 12 rolls of the dice.
