Answer:
3.84% probability that it has a low birth weight
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If we randomly select a baby, what is the probability that it has a low birth weight?
This is the pvalue of Z when X = 2500. So
has a pvalue of 0.0384
3.84% probability that it has a low birth weight
Answer:
Therefore the required equation is
Y=5+3X
Step-by-step explanation:
Given that , Joey has 5 collector stamps.
He gets 3 more stamps each week.
The number of week is X.
1st week he got 3 stamps
2nd week he got (3+3)=2.3 stamps
3rd week he got (3+3+3)=3.3 stamps
Stamp that he got=( the number of week ×3)
Therefore at end of Xth week he got =(X × 3) =3X stamps
Total number of stamps that collected after x week
=5+3X
Therefore the required equation is
Y=5+3X

Answer: 8.4 inch
Step-by-step explanation:
To find the size of the square, just find the square root of 70. Because the area of a square is the side length squared
= 8.3666 rounded to the nearest 10th is 8.4 inch
