Answer:
1/2
Step-by-step explanation:
First things you have to do is figure out how much they increased the iPads by:
$50 • 10 = $500
They increased the iPad price by $500.
Subtract the total amount from the iPad price:
$5,000 - $500 = $4,500
The actual price of 10 iPads, without an increase is $4,500
Now divide that by 10 to get the amount for one iPad:
$4,500 ÷ 10 = $450
One iPad actually costs $450 to make.
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
