Answer:
0.1502 = 15.02% probability that exactly 13 of them use their smartphones in meetings or classes
Step-by-step explanation:
For each adult smartphone users, there are only two possible outcomes. Either they use the phone in meetings or classes, or they do not. The probability of an adult using the phone in these settings is independent of any other adult. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
58% use them in meetings or classes
This means that
20 adult smartphone users are randomly selected
This means that
Find the probability that exactly 13 of them use their smartphones in meetings or classes.
This is . So
0.1502 = 15.02% probability that exactly 13 of them use their smartphones in meetings or classes
Answer:
Height of the oblique prism is 18 units.
Step-by-step explanation:
Volume of an oblique prism =
Area of the base of this prism = 24 square units
And volume of the prism = 144 cubic units
By substituting these values in the formula,
144 =
h =
h =
h = 18 units
Therefore, height of the oblique prism is 18 units.
