Answer:
Step-by-step explanation:
The number of adults that use smartphones in meetings or classes follows a binomial distribution. So, the probability that x adults use their smartphones in meetings or classes is calculated as:
Where, n is the number of identical and independents events, in this case, 7 adults with smartphones. p is the probability of success or the probability that the adult use the smartphone in meeting or classes, in this case, p is equal to 0.58
So, replacing values, we get that the probability that x adults use their smartphones in meetings or classes is:
Now, the probability that at least 2 of them use their smartphones in meetings or classes is calculated as:
Where:
Finally, is equal to:

Answer:
f(3) = 12
Step-by-step explanation:
f(x) = 2x - 12 + 2x²
f(3) = 2(3) - 12 + 2(3)²
f(3) = 6 - 12 + 2(9)
f(3) = -6 + 18
f(3) = 12
Remember that x=3 is being substituted into the equation, so you can apply this to any function rule problem for any value of x.
Answer:
C
Step-by-step explanation:
The distance on the x-axis from 2 to 16 is 14, and the distance on the y-axis from 2 to 8 is 6, so it would be 14 and 6 or 7 and 3
