Answer:
The number of students who were on each bus
Step-by-step explanation:
- Notice there are 70 students, and 70 is the sum of the equation
- We know 6 students weren't on either bus
- The remaining students must represented by 2b
- So if 2b is all the students who got on buses b is half that, representing each group of students per bus
Answer:
About 99.74% of the area is between z = -3 and z = 3
Step-by-step explanation:
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.
Area between z = 3 and z = -3
pvalue of z = 3 subtracted by the pvalue of z = -3
z = 3 has a pvalue of 0.9987
z = -3 has a pvalue of 0.0013
0.9987 - 0.0013 = 0.9974
0.9974*100 = 99.74%
About 99.74% of the area is between z = -3 and z = 3
