4 on the outside with three in the inside
Answer:
The probability is 12.66%.
This is a low probability, so it is unlikely for such a combined sample to test positive.
Step-by-step explanation:
If the probability of being infected is 0.005, the probability of not being infected is 0.995.
Then, to find the probability of at least one of the 27 people being infected P(A), we can find the complementary case: all people are not infected: P(A').
Then we can find P(A) using:
This is a low probability, so it is unlikely for such a combined sample to test positive.
Answer:
1 / 1296
Step-by-step explanation:
Rolling a 1 for one of the cubes is 1 / 6
1 / 6 * 1 / 6 * 1 / 6 * 1 / 6 = 1 / 1296
Answer:
y=3x+1
Step-by-step explanation:
The equation will most likely be in slope-intercept form which is
y=mx+b
(m) is the slope,
(b) is the y intercept
First we must find the slope. The formula for slope is (y1-y2)/(x1-x2)
Which means we take the (y) of the second given point and subtract the (y) if the first given point, then divide that by the (x) of the second given point minus the (x) of the first given point.
(10-(-8)/3-(-3)
18/6
Simplify
3/1
3, our slope is 3.
Now we can put this into our formula
y=3x+b
To find the y intercept we just apply one of the given points. (I'll use (3, 10) but either of them would work.
10=3(3)+b
Now solve
10=9+b
Subtract 9 from each side
1=b
Now we put our slope and y intercept into our formula
y=3x+1.
