Answer:
0.003
Step-by-step explanation:
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (60,000), m is the mean (63500), sd is the standard deviation (6100) and n is the sample size (35).
Replacing we have:
z (60000) = (60000 - 63500) / [6100 / sqrt (35)]
z = -3.39
If we look in the normal distribution table (attached), we have that the probability is 0.0003.
Answer:
8.43
Step-by-step explanation:
8 + 10 + 10 + 10 + 6 + 7 + 8 = 59
59/7 = 8.43 (or keep as improper fraction)
You need use your strategies multiplie it than simplify to k and than move it to E tens
Answer:
y < x
Step-by-step explanation:
Since the line is dotted and shaded down that mean the sign is <.
The slope is rise over run or 3/4.
Since the line intercepts the y-intercept at (0,0) that means that the y-int is 0
So the full equation is y < 3/4 x
