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 :-
Answer:
Im not sure but hiiiiiiiiii.
Step-by-step explanation:
Let's first think about how many possible outcomes there are to a series of coin flips. One that will help us here is that coin flips are <em>independent</em> - the outcome of one flip has no effect on the outcome of the others. What this means is that there are two possible outcomes <em />for <em>each </em>flip: heads or tails. For an example with fewer coins, let's say we were flipping 2 instead of five.
- Flip 1 can either be heads or tails
- Flip 2 can either be heads or tails
So our possible outcomes are HH, HT, TH, and TT. There are two possible second flips <em />for <em>each</em> of the possible first flips, or 2 x 2 = 4 total combinations of flips. Notice that <em>only one </em>of those combinations has zero tails - the combination with all heads.
If we were to flip a coin 5 times, we'd have two possible fifth flips for each of the two possible fourth flips for each of the two possible third flips for... it gets pretty hairy to describe in words, but I've attached a diagram so you can see how quickly it grows out of control. There are 2 x 2 x 2 x 2 x 2 or
possible combinations of heads and tails! But, in fact, we don't even need to sort through these 32 combinations to answer our question. <em>Every</em> combination will contain at least one tail, except one: the combination which contains all heads (HHHHH). Which means the rest of the 31 must contain at least one tail.
This fact will stay the same regardless of the number of coin flips you make: <em>the number of ways that contain at least one tail will always be the total number of combinations minus one (the case where all of the flips are heads).</em>
Answer:
The other line is y= 8x - 7
Step-by-step explanation:
The given equation in two variable is
y= 8x ± 7
The two equations in two variables are:
Ax + By +C=0
P x + Q y +R=0
Now, the condition that these two equations has no solution is if;
A/P = B/Q ≠ P/R
Another condition is in terms of line , if the two lines have same slope.
For example, y= ax + b and , y = ax + p are two lines having same slope means they are parallel, that is they will never intersect.
If the line is , y = 8x + 7, the other line will be, y= 8x - 7
