Answer (<u>assuming it can be in point-slope form)</u>:
Step-by-step explanation:
Use the point-slope formula to write the equation of the line. Substitute real values for
,
, and
in the formula.
Since represents the slope, substitute 1 in its place. Since
and
represent the x and y values of a point the line intersects, substitute the x and y values of (4,3) in its place. Substitute 4 for
and 3 for
. This gives the following equation and answer in point-slope form:
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 .
