Answer:
97%
Step-by-step explanation:
The EVENT space is a subset of the SAMPLE space. In our case:
EVENT SPACE =[(1+5), (2+3), (3+3), (4+2), (5+1)]. In short all favorable outcomes. (against all POSSIBLE outcomes in the SAMPLE space)
Answer:
6 and 8
Step-by-step explanation:
If you look at the list of multiples for each you will see that the lcm of 8 and 6 is 24.
Answer:
0.5161
Step-by-step explanation:
There is a lot of unnecessary information in this question. We only need info for Smartphone A users since our sample size consists of entirely Smartphone A users, and it's asking about them. So ignore any info that isn't about Smartphone A users.
We have (for Smartphone A users):
x = 15, s = 6.4, n = 16
We want: P(14.5 < x < 17)
We need to find the z-scores for the values of 14.5 and 17 using the data for smartphone a users.
See attached photo for the calculation of the 2 z-scores and the probabilities
Basically you are finding the volume of a rectangular prism of 3 by 2 meters cross section and 30 meters length. Volume = (3 m)(2 m)(30 m) = 180 cubic meters.
If 60% of the water has evaporated, 40% is left. Find 40% of 180 cubic meters to answer the 2nd part of this question.
