Answer:
Step-by-step explanation:
If a watch has fewer than three defects, then either 1.) It has no defects, 2.) it has exactly 1 defect, or 3.) it has exactly 2 defects.
1.) The probability that the watch has no defects is 
, because for every chime there is a probability of 
that there is no defect
2.) The probability that the watch has exactly 1 defect is 
times the number of ways you can choose 1 of 75 of the chimes to be defective, which is 
, so the probability that the watch has exactly 1 defect is 
.
3.) For the same reason as 2.), the probability that the watch has exactly two defects is 
Since 1.), 2.), and 3.) are mutually exclusive events, the probability of their union is simply the probability of each of them added together, which is
Answer:
1161 confirmed cases
Step-by-step explanation:
In 2000 the number of cases was 86
Percent means out of a hundred, so if we divide 1350 by 100 we get 13.5.
So, we must multiply 13.5 and 86 to get the amount of cases in 2019.
13.5*86 = 1161 confirmed cases in 2019
Answer:
x + y = 6
Step-by-step explanation:
Standard Form:
y - y1 = m(x - x1)
In this question, the coordinate is (1, 5) with a slope of -1 (the slope is the same as street 1 since street 2 is going to be parallel.
Insert the coordinate and slope into standard form and you'll get this:
y - 5 = -1 ( x - 1 )
y - 5 = -x + 1
y = -x + 6
y + x = 6
hope this helps.
