Answer:
The z-score for the 34-week gestation period baby is 0.61
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
We are told in the question that:
Babies born after a gestation period of 32-35 weeks have a mean weight of 2600 grams and a standard deviation of 660 grams. Also, we are supposing a 34-week gestation period baby weighs 3000grams
The z-score for the 34-week gestation period baby is calculated as:
z = (x-μ)/σ
x = 3000, μ = 2600 σ = 660
z = 3000 - 2600/660
= 400/660
=0.6060606061
Approximately, ≈ 0.61
Note: Let us consider, we need to find the 
and 
.
Given:
In the given figure, BD is the angle bisector of ABC.
To find:
The and .
Solution:
BD is the angle bisector of ABC. So,
Divide both sides by 2.
Now,
And,
Therefore, 
and .
Answer:
14
Step-by-step explanation:
-21+-13+20=14
This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.
In short its kind of like using inverse operation in a way.
Hope this helps and have a nice day

Answer:
$391.52
Step-by-step explanation:
The original price was 100% of the original price.
Since it was sold at 34% off, then since 100% - 34% = 66%, it was sold for 66% of the original price.
Let the original price = x.
66% of x = $258.40
0.66x = 258.4
x = 258.4/0.66
x = 391.52
Answer: $391.52
