If we randomly pick two persons from the population, each one will have a probability of 1-1/28=27/28 of being a non-carrier.
Thus for neither to be non-carrier, the probability is the product of the individual probabilities since the picks are assumed independent (with a large enough population).
Probability = (27/28)*(27/28) = 729/784
or approximately 0.930

Answer:
x = 2
or 14.8
Step-by-step explanation:
First find the missing leg of the right triangle.
8²-3²=x²
x =
then double is to get x in the drawing
x = 2 or 14.8
Answer:
Consistent dependent
3x - 3y = 6 and -x + y = -2
Step-by-step explanation:
<u>Inconsistent</u>: parallel lines, no solutions
<u>Consistent dependent</u>: same line, infinite solutions
<u>Consistent independent</u>: intersects at one point, one solution
Therefore, the pair of lines are Consistent dependent
From inspection of the diagram:
The lines will have equivalent equations.
Therefore, the solution is 3x - 3y = 6 and -x + y = -2
Because:
3x - 3y = 6 ⇒ y = x - 2
-x + y = -2 ⇒ y = x - 2
3s+2c=37
12s+7c=134
To solve we need to multiply the first equation by negative 4
-4(3s+2c=37)
-12s+-8c=-148
12s+7c=134
Cross out the 12s on the two above equations.
-c=-14
c=14
Now let’s plug in value c to first original equation :
3s +2(14)=37
3s+28=37
3s=9
s=3
To recap: senior tickets cost $3 each; children tickets cost $14 each
