Answer: 0.9617
Step-by-step explanation:
Given : The proportion of adults use their phones in meetings or classes : p=0.57
Number of adults randomly selected : n= 9
Let x be the random variable that represents the number of adults use their phones in meetings or classes.
By using binomial probability formula, to find the probability of getting success in x trials.

The probability that at least 3 of them use their smartphones in meetings or classes will be :-

Hence, the required probability is 0.9617 .
We are given the inverse function:
sin-1 (0.65)
We can use a scientific calculator to solve this. Make sure that the mode is in radians and not in degrees
So, the answer is
sin-1 (0.65) = 0.7076 which is in radians
Answer:
x=5
Step-by-step explanation:
x^2+6=31 Find x
Subtract 6 from both sides
x^2=25
take the square root of both sides
x=+5 or -5
