0.015 or 3/200
15 divided by 1000 is 0.015
15/5 is 3 1000/5 is 200
Answer:
B. (0,0)
Step-by-step explanation:
The y-intercept of the equation f(x) = 1/2x lies on the y-axis.
This means we need to set x = 0 and solve for y
1/2(0) = 0
Therefore, (0,0) is the y-intercept of this equation.
Answer:
The mean is 
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:

What is the mean of this normal distribution if the probability of scoring above x = 209 is 0.0228?
This means that when X = 209, Z has a pvalue of 1-0.0228 = 0.9772. So when X = 209, Z = 2.





The mean is 
200,000,000+8,000,000+400+70+8=208,000,478
