Answer:
Step-by-step explanation:
The given information is expressed as
Side effect no side effect total
Adult 7 43 50
Children 22 28 50
Total 29 71 100
Probability is expressed as
Number of favorable outcomes/number of total outcomes
For the probability that an adult has side effects,
Total number of outcomes = 50
Number of favorable outcomes = 7
Probability that an adult has side effects = 7/50 = 0.14
For the probability that a child has side effects,
Total number of outcomes = 50
Number of favorable outcomes = 22
Probability that an adult has side effects = 22/50 = 0.44
Therefore, it is more likely that a child has side effects compared to an adult
According to HL theorem if one leg and hypotenuse of one right triangle are equal to one leg and hypotenuse of other right triangle, then the triangles are congruent.
By using this theorem we can set up the system of equations as follows:
x=y+1 ...(1)
2x+3= 3y + 3 ..(2)
By using equation (1) next step is to plug in y+1 for x in equation (2). So,
2 ( y + 1) + 3 = 3y + 3
2y + 2 + 3 = 3y + 3 By using distribution property.
2y + 5 = 3y + 3
2y + 5 - 5 = 3y + 3 - 5 Subtract 5 from each side.
2y = 3y - 2
2y - 3y = -2 Subtract 3y from each sides.
-y = -2
So, y=2
Next step is to plug in y=2 in equation (1) to get the value of x. Hence,
x= 2+1
=3
So, x=3 and y=2 make these triangles congruent.
So, the correct choice is 3. x = 3, y = 2.
