Step-by-step explanation:
1) Use point-slope formula to find the slope-intercept form (or y = mx + b form) of the equation. m represents the slope, and
and
represent the x and y values of a point the line intersects. So, substitute
for m, -4 for
, and 7 for
. Then, simplify and isolate y on the left side like so:
Answer:
There is an 84.97% probability that at least six wear glasses.
Step-by-step explanation:
For each adult over 50, there are only two possible outcomes. Either they wear glasses, or they do not. This means that we use the binomial probability distribution to solve this problem.
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 combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
