Answer:
2
Explanation:
Degree 4 is the term with the exponent that is 4. The 2 in front of the x is the coefficient.
Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)
The problem is missing some parts but here are the answers:
(a) x is more than 60
z(60) = (60-85)/25 = -1
P(x > 60) = P(z > -1) = 0.158655
(b) x is less than 110
z(110) = (110-85)/25 = 1
P(x < 110) = P(z < 1) = 0.841345
Answer:
-262.8
Step-by-step explanation:
i don't know how to do the step by Step T. T, hooe it helps tho ^^
Assuming the n data values are independent draws from a Poisson distributed population with parameter λ , the MLE of λ from the sample is the sample mean, i.e.

Numerous proves are available online.
It would be x = 4 (plus or minus) the square root of 3.
Hope this helps.
