Answer:
31.25
Step-by-step explanation:
Divide 250 by 8=31.25
A) x + y = 2
B) x * y = -8
B) y = -8 / x we can substitute this into equation A
A) x + -8 /x = 2 multiplying both sides by "x"
A) x² -8 = 2x
x² +2x -8 = 0
(x + 4) * (x -2)
The 2 numbers are -4 and 2
For the given set of numbers:
<span>{1,2,3,4, 5, 6, 7, 8, 9, 10}
the number of elements
n=10
the total number of subsets is given by:
2^10=1024
</span>
Answer: a) 0.8665
b) 0.8190
Step-by-step explanation:
Given : The partial pressure of oxygen PaO2 is a measure ofthe amount of oxygen in the blood. Assume that the distribution ofPaO2 levels among newborns has a
38 mmHg and
9 mmHg.
If we take a random sample n= 25 newborns, then using formula
, we have
At x= 36

At x= 41

Using table for z-values, the probability that the sample mean will be greater than 36 :

The probability that the sample mean will be between 36 and 41 :-
