Answer:
0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.
Step-by-step explanation:
We are given the following information:
We treat adult using smartphones in meetings or classes as a success.
P(Adult using smartphone) = 46% = 0.46
Then the number of adults follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 9
We have to evaluate:
0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.
Answer:
Any number that is multiples of 33,6,9,12
Step-by-step explanation:
Have a great day!!
The answer is 3.
the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
Answer: 9%
Step-by-step explanation:
