Answer:
Y=(-x/2)-3
Step-by-step explanation:
You have two points:
(0,-3) and (-4,-1)
The formula of line trough two points is:
(Y-y1)/(y2-y1)=(x-x1)/(x2-x1)
So put these two point like (x1,y1) and (x2,y2) you will get
(Y+3)/(-1+3)=(x-0)/(-4-0)
Y+3=2x/(-4)
Y=-x/2-3
Answer:
180 students brought their lunch to school on Thursday
Step-by-step explanation:
We are told that out of 900, 5% of the students brought their lunch to school everyday
So the number that brought their lunch on Thursday will be;
5% of 900
= 5/100 * 900 = 180
The probability that at least one of them has been vaccinated is equal to 98.5% if 65% of the people have been vaccinated.
Considering P to be the probability that at least one is vaccinated and q to be the probability that none of the four are vaccinated; the sum of all the probabilities must equal 1; therefore,
P = 1 - q
As 65% of the population is vaccinated, therefore 35% are not vaccinated. Thus any person has a probability of 0.35 of not being vaccinated;
q = 0.35^4 = 0.015
P = 1 - 0.015
P = 0.985
Converting it into percentage;
P = 0.985 × 100 = 98.5%
Therefore the probability that at least one of them has been vaccinated is calculated to be 98.5%
